Effective Leadership Behavior: What We Know and
What Questions Need More Attention
by Gary Yukl
Executive Overview
Extensive research on leadership behavior during the past half century has yielded many different behavior
taxonomies and a lack of clear results about effective behaviors. One purpose of this article is to describe
what has been learned about effective leadership behavior in organizations. A hierarchical taxonomy with
four meta-categories and 15 specific component behaviors was used to interpret results in the diverse and
extensive literature and to identify conditions that influence the effectiveness of these behaviors. Limita-
tions and potential extensions of the hierarchical taxonomy are discussed, and suggestions for improving
research on effective leadership behavior are provided.
The essence of leadership in organizations is
influencing and facilitating individual and col-
lective efforts to accomplish shared objectives.
Leaders can improve the performance of a team or
organization by influencing the processes that de-
termine performance. An important objective in
much of the leadership research has been to iden-
tify aspects of behavior that explain leader influ-
ence on the performance of a team, work unit, or
organization. To be highly useful for designing
research and formulating theories, leader behavior
categories should be observable, distinct, measur-
able, and relevant for many types of leaders, and
taxonomies of leader behaviors should be compre-
hensive but parsimonious.
Thousands of studies on leader behavior and its
effects have been conducted over the past half
century, but the bewildering variety of behavior
constructs used for this research makes it difficult
to compare and integrate the findings (Bass, 2008;
Yukl, in press). The behavior taxonomies guiding
past research have substantial differences in the
number and type of behaviors they include. Some
taxonomies have only a few broadly defined be-
havior meta-categories, whereas other taxonomies
have a larger number of narrowly defined behavior
categories. Some taxonomies are intended to
cover the full range of leader behaviors, whereas
others include only the behaviors identified in a
particular leadership theory. Some taxonomies
describe leader behaviors used to motivate indi-
vidual subordinates, whereas other taxonomies de-
scribe behaviors used to lead groups or organiza-
tions. Some taxonomies include other types of
constructs along with behaviors, such as leader
roles, skills, and values. Additional confusion is
created by lack of consistency in the use of cate-
gory labels. Sometimes different terms are used to
refer to the same type of behavior, and sometimes
the same term is used for different forms of
behavior.
The primary purpose of this article is to review
what has been learned about effective leadership
behavior from research conducted over more than
half a century. To integrate results from a large
number of studies with many different ways of

classifying and measuring leadership behavior, it
was first necessary to develop a comprehensive
behavior taxonomy. The article begins by describ-
ing how decades of behavior research provides the
basis for a hierarchical taxonomy with four broad
meta-categories and 15 specific component be-
haviors. Next is a brief overview of research on
the effects of widely used behavior categories, fol-
lowed by a more detailed description of what has
been learned about the relevance of each specific
behavior in the hierarchical taxonomy. Several
conditions that influence the effects of the behav-
iors are described, and the need for more research
on them is explained. The article ends with a
summary and suggestions for improving future
research.
Research on Behavior Taxonomies
The method used most often to identify catego-
ries of leadership behavior is factor analysis
of behavior description questionnaires. This
method is most useful when clear, relevant items
are selected for the initial questionnaire and re-
spondents are able to remember the leader’s past
behavior and provide accurate ratings. Unfortu-
nately, the selection of behavior items for a ques-
tionnaire is usually influenced by preconceptions
about effective leadership or the desire to develop
a measure of key behaviors in a leadership theory.
The sample of respondents is seldom systematic,
and the accuracy of most behavior questionnaires
is seriously reduced by respondent biases and at-
tributions. Finally, the basic assumptions of factor
analysis (high correlation among examples from
the same category) do not apply very well when a
behavior category includes several alternative
ways to achieve the same objective and a leader
needs to use only one or two of them. The limi-
tations of this method may help to explain the
substantial differences among leader behavior
taxonomies.
Another common method for identifying dis-
tinct behavior categories is to have subject matter
experts sort behavior descriptions into categories
based on similarity of purpose and content, but
this method also has limitations. The selection of
categories may be biased by prior assumptions and
implicit leadership theories, and disagreements
among subject matter experts are not easily re-
solved. A behavior taxonomy is more likely to be
useful if it is based on multiple methods and is
supported by research on the antecedents and
outcomes of the behaviors.
From 1950 to 1980 most of the research on
leadership behavior was focused on explaining
how leaders influence the attitudes and perfor-
mance of individual subordinates. In the early
survey research, factor analysis of leadership be-
havior questionnaires found support for two
broadly defined behavior categories involving
task-oriented and relations-oriented behaviors.
Different labels were used for these meta-catego-
ries, including initiating structure and consider-
ation (Fleishman, 1953; Halpin & Winer, 1957),
production-centered and employee-centered lead-
ership (Likert, 1961), instrumental and supportive
leadership (House, 1971), and performance and
maintenance behavior (Misumi & Peterson,
1985). The specific behaviors defining the two
meta-categories varied somewhat from one taxon-
omy to another, and some relevant behaviors
were not adequately represented in any of these
taxonomies. Finding the two meta-categories was
a good start, but researchers failed to conduct
systematic follow-up research to build on the ini-
tial discoveries.
Leadership behaviors directly concerned with
encouraging and facilitating change did not get
much attention in the early leadership research.
Change behaviors are more relevant for execu-
tives than for the low-level leaders studied in
much of the early research, and they are more
important for the dynamic, uncertain environ-
ments that have become so common for organi-
zations in recent decades. In the 1980s one or two
specific change-oriented behaviors were included
in questionnaires used to measure charismatic and
transformational leadership, but leading change
was still not explicitly recognized as a distinct
meta-category. Researchers in Sweden and the
United States (Ekvall & Arvonen, 1991; Yukl,
1999; Yukl, Gordon, & Taber, 2002) eventually
found evidence for the construct validity of a
leading-change meta-category. The classification
of change-oriented behavior as a distinct and
2012 67Yukl
meaningful meta-category provided important
new insights about effective leadership.
In most of the early research on leadership
behavior the focus was on describing how leaders
influence subordinates and internal activities in
the work unit. Leader behavior descriptions were
usually obtained from subordinates who had little
opportunity to observe their leaders interacting
with people outside the work unit. Thus, it is not
surprising that few leadership studies examined
external (“boundary-spanning”) behavior, and
only a few leader behavior taxonomies included
any external behaviors (e.g., Stogdill, Goode, &
Day, 1962). However, in the late 1970s and early
1980s, descriptive research on managers found
that it is important to influence bosses, peers, and
outsiders as well as subordinates (Kaplan, 1984;
Kotter, 1982; Mintzberg, 1973), and later research
on teams found that boundary-spanning behavior
is important for effective team performance (e.g.,
Ancona & Caldwell, 1992; Joshi, Pandey, & Han,
2009; Marrone, 2010). The importance and
uniqueness of external leadership behavior pro-
vides justification for classifying it as a separate
meta-category.
Hierarchical Behavior Taxonomy
The hierarchical taxonomy proposed in this
article describes leadership behaviors used
to influence the performance of a team, work
unit, or organization. The four meta-categories
and their component behaviors are shown in
Table 1. Each meta-category has a different
primary objective, but the objectives all involve
determinants of performance. For task-oriented
behavior the primary objective is to accomplish
work in an efficient and reliable way. For rela-
tions-oriented behavior the primary objective is
to increase the quality of human resources and
relations, which is sometimes called “human
capital.” For change-oriented behavior the pri-
mary objectives are to increase innovation, col-
lective learning, and adaptation to the external
environment. For external leadership behavior
the primary objectives are to acquire necessary
information and resources, and to promote and
defend the interests of the team or organization.
In addition to these differences in primary objec-
tives, each meta-category includes unique specific
behaviors for achieving the objectives. The rele-
vance of each component behavior depends on
aspects of the situation, and the effect is not
always positive for the primary objective or for
other outcomes.
The proposed taxonomy builds on the exten-
sive factor analysis research by Yukl and col-
leagues (2002), and it also reflects findings in
other taxonomic research linking specific behav-
iors to the performance of a team or organization.
The three meta-categories in the Yukl and col-
leagues (2002) taxonomy were retained, but an-
other component on task-oriented behavior
(problem solving) was added, consulting and del-
egating were combined into a broader relations-
oriented component (empowering), and taking
risks to promote change was included in a broader
change-oriented component (advocating change).
The new taxonomy also includes a fourth meta-
category (external behavior). Two of the compo-
nent behaviors (networking and representing)
were not included in the questionnaire used for
the Yukl and colleagues (2002) research, and the
third component (external monitoring) was in
their questionnaire but it was included in the
change-oriented meta-category.

Overview of Research on Effects of
Leader Behavior
Much of the research on effects of leader be-
havior has been guided by popular leadership
theories that emphasized one or two broadly
defined behaviors. Early leadership theories such
as path-goal theory (House, 1971), leadership sub-
stitutes theory (Kerr & Jermier, 1978), situational
leadership theory (Hersey & Blanchard, 1977),
and the managerial grid (Blake & Mouton, 1964)
emphasized task-oriented and relations-oriented
behavior, and these meta-categories were used in
much of the research conducted from 1960 to
1980. Reviews and meta-analyses of results from
hundreds of studies concluded that both meta-
categories are related to independent measures of
leadership effectiveness (DeRue, Nahrgang, Well-
man, & Humphrey, 2011; Judge, Piccolo, &
Ilies, 2004).
Since the 1980s, much of the research on the
effects of leadership behavior has been based on
theories of transformational and charismatic lead-
ership (Avolio, Bass, & Jung, 1999; Bass, 1985;
Conger & Kanungo, 1987; House, 1977; Shamir,
House, & Arthur, 1993). As in the earlier re-
search, most of these studies reported results only
for composite scores on behavior meta-categories
included in the theory. Reviews and meta-analy-
ses of this research found that transformational
leadership was related to indicators of leadership
effectiveness in a majority of studies, but results
were inconsistent for transactional leadership and
charismatic leadership (De Groot, Kiker, & Cross,
2000; Judge & Piccolo, 2004; Lowe, Kroeck, &
Sivasubramaniam, 1996; Wang, Oh, Courtright,
& Colbert, 2011; Yukl, 2013).
The research on effects of broadly defined be-
haviors has limitations that make the results dif-
ficult to interpret. The limitations include differ-
ences in the way behavior is defined and measured
from study to study, use of composite scores based
on diverse component behaviors that do not have
the same effects, the exclusion of other relevant
behaviors likely to be confounded with the mea-
sured behaviors, and over-reliance on weak re-
search methods such as same-source survey stud-
ies. The results found for independent measures of
leadership effectiveness were much weaker than
results found for same-source measures, especially
when objective performance measures were
used (Burke et al., 2006; Kaiser, Hogan, &
Craig, 2008).
The popularity of survey research on meta-
categories may have inhibited research on effects
of specific behaviors, because the number of stud-
ies on them is much smaller. The research on
effects of specific leadership behaviors included
several types of studies. Some studies used a be-
havior description questionnaire, but other studies
used behavior descriptions from observation, dia-
ries, or critical incidents. Several multiple-case
studies used interviews, records, and other data
collection methods to investigate how leader de-
cisions and actions influenced performance for a
team or organization, and the behavior of effective
and ineffective leaders was usually compared. A
few studies used laboratory or field experiments in
which leader behavior was manipulated to assess
the effects on subordinate performance. The find-
ings in this research provide evidence that each of
the 15 specific behaviors in the proposed taxon-
omy is relevant for effective leadership.
Effectiveness of Specific Leader Behaviors
In this section, the relevance of each specific
component behavior is briefly explained, and
the research linking it to effective leadership is
cited. The research includes studies on dyadic,
group, and organizational leadership. Most studies
examined effects of behavior by individual leaders
and included an independent source of informa-
tion about leadership effectiveness, such as ratings
by superiors or objective performance measures.
Task-Oriented Behaviors
As noted earlier, the primary purpose of task-
oriented behaviors is to ensure that people, equip-
ment, and other resources are used in an efficient
way to accomplish the mission of a group or or-
ganization. Specific component behaviors include
planning and organizing work-unit activities, clar-
ifying roles and objectives, monitoring work-unit
operations, and resolving work-related problems.

Planning
This broadly defined behavior includes making
decisions about objectives and priorities, organiz-
ing work, assigning responsibilities, scheduling ac-
tivities, and allocating resources among different
activities. More specifically, activity planning in-
volves scheduling activities and assigning tasks in
a way that will accomplish task objectives and
avoid delays, duplication of effort, and wasted
resources. Project planning includes identifying
essential action steps; determining an appropriate
sequence and schedule for them; deciding who
should do each action step; and determining what
supplies, equipment, and other resources are nec-
essary. The planning often requires information
provided by other people such as subordinates,
peers, bosses, and outsiders. Negative forms of this
behavior include making plans that are superficial
or unrealistic. Several types of research provide
evidence that planning can enhance a leader’s
effectiveness, including survey studies (e.g., Kim
& Yukl, 1995; Shipper, 1991; Shipper & Dillard,
2000; Shipper & Wilson, 1992; Yukl, Wall, &
Lepsinger, 1990), incident and diary studies
(e.g., Ancona & Caldwell, 1992; Morse & Wag-
ner, 1978; Yukl & Van Fleet, 1982), and mul-
tiple-case studies (e.g., Kotter, 1982; Van Fleet
& Yukl, 1986).
Clarifying
Leaders use clarifying to ensure that people under-
stand what to do, how to do it, and the expected
results. Clarifying includes explaining work re-
sponsibilities; assigning tasks; communicating ob-
jectives, priorities, and deadlines; setting perfor-
mance standards; and explaining any relevant
rules, policies, and standard procedures. Setting
clear, specific, and challenging but realistic goals
usually improves performance by a group (Locke
& Latham, 1990). Negative forms of clarifying
include failing to provide clear assignments, set-
ting vague or easy goals, providing inconsistent
instructions that create role ambiguity, and giving
excessively detailed directions (micromanaging).
Evidence that clarifying can enhance leadership
effectiveness is provided by survey studies (e.g.,
Kim & Yukl, 1995; Shipper, 1991; Shipper &
Dillard, 2000; Shipper & Wilson, 1992; Yukl &
Kanuk, 1979; Yukl et al., 1990), incident and
diary studies (e.g., Amabile, Schatzel, Moneta, &
Kramer, 2004; Yukl & Van Fleet, 1982), compar-
ative case studies (e.g., Van Fleet & Yukl, 1986),
an executive team simulation study (Zalatan,
2005), a laboratory experiment (Kirkpatrick &
Locke, 1996), and field experiments (Latham &
Baldes, 1975; Latham & Yukl, 1976).
Monitoring
Leaders use monitoring to assess whether people
are carrying out their assigned tasks, the work is
progressing as planned, and tasks are being per-
formed adequately. Information gathered from
monitoring is used to identify problems and op-
portunities and to determine if changes are needed
in plans and procedures. Information from moni-
toring can also be used to guide the use of rela-
tions-oriented behaviors such as praise or coach-
ing. There are many different ways to monitor
operations, including directly observing activities,
examining recorded activities or communications,
using information systems, examining required re-
ports, and holding performance review sessions.
Negative examples include types of monitoring
that are intrusive, excessive, superficial, or irrele-
vant. Evidence that monitoring can improve lead-
ership effectiveness is provided by survey studies
(e.g., Kim & Yukl, 1995; Wang, Tsui, & Xin,
2011; Yukl et al., 1990), studies using direct ob-
servation or diaries (e.g., Amabile et al., 2004;
Brewer, Wilson, & Beck, 1994; Komaki, 1986),
comparative case studies (e.g., Peters & Austin,
1975; Van Fleet & Yukl, 1986), and a laboratory
experiment (Larson & Callahan, 1990).
Problem Solving
Leaders use problem solving to deal with disrup-
tions of normal operations and member behavior
that is illegal, destructive, or unsafe. Serious dis-
ruptions of the work usually require leadership
intervention, and other terms for problem solving
include “crisis management” and “disturbance
handling.” Effective leaders try to quickly identify
the cause of the problem, and they provide firm,
confident direction to their team or work unit as
they cope with the problem. It is important to
70 NovemberAcademy of Management Perspectives
recognize the difference between operational
problems that can be resolved quickly and com-
plex problems likely to require change-oriented
behaviors and involvement by other leaders. Prob-
lem solving also includes disciplinary actions in
response to destructive, dangerous, or illegal be-
havior by members of the work unit (e.g., theft,
sabotage, violation of safety regulations, falsifica-
tion of records). Problem solving can be proactive
as well as reactive, and effective leaders take the
initiative to identify likely problems and deter-
mine how to avoid them or minimize their adverse
effects. Many things can be done to prepare the
work unit or organization to respond effectively to
predictable types of disruptions such as accidents,
equipment failures, natural disasters, health emer-
gencies, supply shortages, computer hacking, and
terrorist attacks. Negative forms of problem solv-
ing include ignoring signs of a serious problem,
making a hasty response before identifying the
cause of the problem, discouraging useful input
from subordinates, and reacting in ways that cre-
ate more serious problems. Evidence that problem
solving is related to leadership effectiveness is
provided by survey studies (e.g., Kim & Yukl,
1995; Morgeson, 2005; Yukl & Van Fleet, 1982;
Yukl et al., 1990), studies using critical incidents
or diaries (e.g., Amabile et al., 2004; Boyatzis,
1982; Yukl & Van Fleet, 1982), and comparative
case studies (e.g., Van Fleet & Yukl, 1986).
Relations-Oriented Behaviors
Leaders use relations-oriented behaviors to en-
hance member skills, the leader–member relation-
ship, identification with the work unit or organi-
zation, and commitment to the mission. Specific
component behaviors include supporting, devel-
oping, recognizing, and empowering.
Supporting
Leaders use supporting to show positive regard,
build cooperative relationships, and help people
cope with stressful situations. Examples include
showing concern for the needs and feelings of
individual team members, listening carefully when
a member is worried or upset, providing support
and encouragement when there is a difficult or
stressful task, and expressing confidence that
someone can perform a difficult task. Supporting
also includes encouraging cooperation and mutual
trust and mediating conflicts among subordinates.
A significant relationship between supporting and
leadership effectiveness was found in survey stud-
ies (e.g., Dorfman, Howell, Cotton, & Tate, 1992;
Kim & Yukl, 1995; McDonough & Barczak, 1991;
Yukl & Van Fleet, 1982; Yukl et al., 1990), in
studies using incidents or diaries (e.g., Amabile et
al., 2004; Druskat & Wheeler, 2003; Yukl & Van
Fleet, 1982), and in a laboratory experiment
(Gilmore, Beehr, & Richter, 1979). Negative
forms of supporting include hostile, abusive be-
havior. Research on abusive supervision finds that
it reduces trust, elicits resentment, and invites
retaliation (Mitchell & Ambrose, 2007; Tep-
per, 2000).
Developing
Leaders use developing to increase the skills and
confidence of work-unit members and to facilitate
their career advancement. Examples of developing
include providing helpful career advice, informing
people about relevant training opportunities,
making assignments that allow learning from ex-
perience, providing developmental coaching
when it is needed, asking a group member to
provide instruction to a new member, arranging
practice sessions or simulations to help members
improve their skills, and providing opportunities
to apply new skills on the job. Developing is
mostly done with a subordinate or team, but some
aspects may be used with a colleague or an inex-
perienced new boss. A positive relationship be-
tween developing subordinate skills and indicators
of leadership effectiveness was found in survey
studies (e.g., Kim & Yukl, 1995; Yukl et al., 1990),
in research using critical incidents and interviews
(e.g., Morse & Wagner, 1978), in comparative
case studies (e.g., Bradford & Cohen, 1984; Ed-
mondson, 2003b; Peters & Austin, 1985), and in
an experiment (Tannenbaum, Smith-Jentsch,
Salas, & Brannick, 1998).
Recognizing
Leaders use praise and other forms of recognition
to show appreciation to others for effective per-
2012 71Yukl
formance, significant achievements, and impor-
tant contributions to the team or organization.
Recognizing may involve an award presented in a
ceremony, or the leader’s recommendation for a
tangible reward such as a pay increase or bonus.
Effective leaders are proactive in looking for
things that deserve recognition, and they provide
recognition that is sincere, specific, and timely.
Negative examples include providing excessive
recognition for trivial achievements, failing to
recognize an important contribution, and taking
credit for another person’s ideas or achievements.
Evidence for the positive effects of praise and
recognition on subordinate performance is pro-
vided by survey research (e.g., Kim & Yukl, 1995;
Shipper, 1991; Shipper & Wilson, 1992; Yukl &
Kanuk, 1979), research with incidents or diaries
(e.g., Amabile et al., 2004; Atwater, Dionne,
Avolio, Camobreco, & Lau, 1996), and descrip-
tive case studies (e.g., Kouzes & Posner, 1987;
Peters & Waterman, 1982). A field experiment
found that increased use of praise by supervisors
improved performance by employees (Wikoff, An-
derson, & Crowell, 1983).
Empowering
Leaders can empower subordinates by giving them
more autonomy and influence over decisions
about the work. One empowering decision proce-
dure called consultation includes asking other
people for ideas and suggestions and taking them
into consideration when making a decision. An
even stronger empowering decision procedure
called delegation involves giving an individual or
group the authority to make decisions formerly
made by the leader. When used in appropriate
ways, empowerment can increase decision quality,
decision acceptance, job satisfaction, and skill de-
velopment (Vroom & Yetton, 1973; Yukl, in
press). Ineffective forms of the behavior include
using the supposedly empowering decision proce-
dures in a way that allows no real influence, and
giving too much autonomy or influence to people
who are unable or unwilling to make good
decisions.
The term “participative leadership” is some-
times used to describe extensive use of empower-
ing decision procedures, and many studies have
assessed the effects on subordinate attitudes and
performance. Meta-analyses of this research found
a weak positive relationship with leadership effec-
tiveness (e.g., Miller & Monge, 1986; Spector,
1986; Wagner & Gooding, 1987). Stronger evi-
dence that specific empowering decision proce-
dures are related to leadership effectiveness has
been provided by survey studies that measured a
leader’s use of consultation and delegation (e.g.,
Kim & Yukl, 1995; Shipper & Wilson, 1992; Yukl
et al., 1990), by research with critical incidents
and diaries (e.g., Amabile and colleagues, 2004;
Druskat & Wheeler, 2003), by comparative case
studies (e.g., Bradford & Cohen, 1984; Edmond-
son, 2003b; Kanter, 1983; Leana, 1986), and by
field experiments (Bragg & Andrews, 1973; Coch
& French, 1948; Korsgaard, Schweiger, & Sapi-
enza, 1995).
Change-Oriented Behaviors
Leaders use change-oriented behaviors to increase
innovation, collective learning, and adaptation to
external changes. Specific component behaviors
include advocating change, articulating an inspir-
ing vision, encouraging innovation, and encour-
aging collective learning. The first two compo-
nent behaviors emphasize leader initiation and
encouragement of change, whereas the second
two component behaviors emphasize leader facil-
itation of emergent change processes.
Advocating Change
Explaining why change is urgently needed is a key
leadership behavior in theories of change manage-
ment (e.g., Kotter, 1996; Nadler et al., 1995).
When changes in the environment are gradual
and no obvious crisis has occurred, people may fail
to recognize emerging threats or opportunities.
Leaders can provide information showing how
similar work units or competitors have better per-
formance. Leaders can explain the undesirable
outcomes that are likely to occur if emerging prob-
lems are ignored or new opportunities are ex-
ploited by competitors. Influencing people to ac-
cept the need for change involves increasing their
awareness of problems without creating an exces-
sive level of distress that causes either denial of
the problem or acceptance of easy but ineffective
72 NovemberAcademy of Management Perspectives
solutions (Heifetz, 1994). Resistance to change is
common in organizations, and courage is required
to persistently push for it when the leader’s career
is at risk. It is easier to gain support for making
innovative changes when a leader can frame un-
favorable events as an opportunity rather than a
threat. The leader can propose a strategy for re-
sponding to a threat or opportunity, but involving
people with relevant expertise usually results in a
better strategy and more commitment to imple-
ment it. Negative forms of the behavior include
advocating a costly major change when only in-
cremental adjustments are necessary (McClelland,
Liang, & Barker, 2009), or advocating acceptance
of a costly new initiative without considering the
serious risks and obstacles (Finkelstein, 2003). Ev-
idence that advocating relevant change is related
to effective leadership is provided by comparative
case studies (e.g., Beer, 1988; Edmondson, 2003b;
Heifetz, 1994; Kotter & Cohen, 2002; Tichy &
Devanna, 1986) and by an experiment using a
simulated team task (Marks, Zaccaro, & Ma-
thieu, 2000).
Envisioning Change
An effective way for leaders to build commitment
to new strategies and initiatives is to articulate a
clear, appealing vision of what can be attained by
the work unit or organization. A vision will be
more inspiring and motivating if it is relevant to
the values, ideals, and needs of followers and is
communicated with colorful, emotional language
(e.g., vivid imagery, metaphors, stories, symbols,
and slogans). An ambitious, innovative vision is
usually risky, and members of the team or organi-
zation are more likely to accept it if the leader can
build confidence that they will be successful (Na-
dler, 1988). However, an appealing vision based
on false assumptions and wishful thinking can
divert attention from innovative solutions that
are more likely to be successful (Mumford, Scott,
Gaddis, & Strange, 2002). Consistently pursuing a
risky and unrealistic vision is a major reason for
serious performance declines in organizations with
a charismatic leader (Finkelstein, 2003). Evidence
that articulating an appealing and inspiring vision
is relevant for effective leadership is provided by
survey studies (e.g., Baum, Locke, & Kirkpatrick,

Feldman, & Garland, 2001; Kotter & Cohen,
2002; Roberts, 1985; Tichy & Devanna, 1986),
and laboratory experiments (e.g., Awamleh &
Gardner, 1999; Kirkpatrick & Locke, 1996).
Encouraging Innovation
There are many ways leaders can encourage, nur-
ture, and facilitate creative ideas and innovation
in a team or organization. Other terms that de-
scribe aspects of this behavior include “intellec-
tual stimulation” and “encouraging innovative
thinking.” Leaders can encourage people to look
at problems from different perspectives, to think
outside the box when solving problems, to exper-
iment with new ideas, and to find ideas in other
fields that can be applied to their current problem
or task. By creating a climate of psychological
safety and mutual trust, a leader can encourage
members of the team or organization to suggest
novel ideas. Leaders can also help to create an
organizational culture that values creativity and
entrepreneurial activities, they can provide oppor-
tunities and resources to develop new products or
services, and they can serve as champions or spon-
sors for acceptance of innovative proposals. Evi-
dence linking this type of change behavior to
indicators of effective leadership is provided by
survey studies (e.g., Bass & Yammarino, 1991;
Elenkov, Judge, & Wright, 2005; Howell & Avo-
lio, 1993; Keller, 2006; Waldman, Javidan, &
Varella, 2004; Zhu, Chew & Spangler, 2005),
comparative case studies (e.g., Edmondson,
2003b; Eisenhardt, 1989; Kanter, 1983; Peters &
Austin, 1985), a laboratory experiment (Red-
mond, Mumford, & Teach, 1993), and a field
experiment (Barling, Weber, & Kelloway, 1996).
Facilitating Collective Learning
There are many ways leaders can encourage and
facilitate collective learning of new knowledge
relevant for improving the performance of a group
or organization (Berson, Nemanich, Waldman,
Galvin, & Keller, 2006; Popper & Lipshitz, 1998).
Collective learning may involve improvement of
2012 73Yukl
current strategies and work methods (exploita-
tion) or discovery of new ones (exploration).
Leaders can support internal activities used to
discover new knowledge (e.g., research projects,
small-scale experiments) or activities to acquire
new knowledge from external sources. Leaders can
use practices that facilitate learning by an opera-
tions team (e.g., after-activity reviews, bench-
marking) or a project development team (e.g.,
providing resources and opportunity to test new
ideas). By helping to create a climate of psycho-
logical safety, leaders can increase learning from
mistakes and failures. To enhance collective
learning from both successes and failures, leaders
must avoid common tendencies to misinterpret
causes and over-generalize implications (Baumard
& Starbuck, 2005). Leaders can help their teams
to better recognize failures, analyze their causes,
and identify remedies to avoid a future recurrence
(Cannon & Edmondson, 2005). Leaders can also
influence how new knowledge or a new technol-
ogy is diffused and applied by explaining why it is
important, guiding the process of learning how to
use it, and encouraging the use of knowledge-
sharing programs. Leaders can help people de-
velop a better understanding about the determi-
nants of organizational performance. More
accurate, shared mental models will improve stra-
tegic decisions and organizational performance.
Evidence that facilitating collective learning is
related to effective leadership is provided by com-
parative case studies (e.g., Baumard & Starbuck,
2005; Beer, 1988; Edmondson, 1999; Edmondson
2002, 2003a) and by experiments with teams (e.g.,
Ellis, Mendel, & Nir, 2006; Tannenbaum, Smith-
Jentsch, & Behson, 1998).
External Leadership Behaviors
In addition to influencing internal events in the
work unit, most leaders can facilitate performance
with behaviors that provide relevant information
about outside events, get necessary resources and
assistance, and promote the reputation and inter-
ests of the work unit. Three distinct external
behaviors include networking, external monitor-
ing, and representing.
Networking
It is important for most leaders to build and main-
tain favorable relationships with peers, superiors,
and outsiders who can provide information, re-
sources, and political support (Ibarra & Hunter,
2007; Kaplan, 1984; Kotter, 1982; Michael &
Yukl, 1973). Networking includes attending
meetings, professional conferences, and ceremo-
nies; joining relevant associations, clubs, and so-
cial networks; socializing informally or communi-
cating with network members; and using
relationship-building tactics (e.g., finding com-
mon interests, doing favors, using ingratiation). In
addition to developing their own networks, lead-
ers can encourage relevant networking by subor-
dinates. Networking is a source of information
that facilitates other leadership behaviors, but
there are potential costs if it is overdone (e.g.,
time demands, role conflicts). Evidence that net-
working can facilitate leadership effectiveness is
provided by survey studies (e.g., Kim & Yukl,
1995; Yukl et al., 1990); studies with incident
diaries, interviews, or observation (e.g., Amabile
et al., 2004; Ancona & Caldwell, 1992; Druskat &
Wheeler, 2003; Luthans, Rosenkrantz, & Hen-
nessey, 1985); and comparative case studies (e.g.,
Katz & Tushman, 1983; Tushman & Katz, 1980).
External Monitoring
This external behavior includes analyzing infor-
mation about relevant events and changes in the
external environment and identifying threats and
opportunities for the leader’s group or organiza-
tion. Information may be acquired from the lead-
er’s network of contacts with outsiders, by study-
ing relevant publications and industry reports, by
conducting market research, and by studying the
decisions and actions of competitors and oppo-
nents. Other terms for external monitoring are
“environmental scanning” or “scouting.” The ex-
tent to which top executives accurately perceive
the external environment of their organization is
related to financial performance (Bourgeois,
1985), and it is more important when the envi-
ronment is dynamic and competitive. For a team
or work unit in an organization, the importance of
external monitoring depends on how much their
74 NovemberAcademy of Management Perspectives
performance is likely to be affected by external
events. Likewise, the need to closely monitor
events in other subunits is determined by depen-
dence on them. Evidence that external monitor-
ing is related to indicators of effective leadership is
provided by survey research (Dol-
linger, 1984), research with critical incidents and
diaries (e.g., Druskat & Wheeler, 2003; Katz &
Tushman, 1981; Luthans et al., 1985), research
with comparative cases (e.g., Geletkanycz &
Hambrick, 1997; Grinyer, Mayes, & McKiernan,
1990; Van Fleet & Yukl, 1986), and a study using
an executive team simulation (Zalatan, 2005).
Representing
Leaders usually represent their team or organiza-
tion in transactions with superiors, peers, and out-
siders (e.g., clients, suppliers, investors, and joint
venture partners). Representing includes lobbying
for resources and assistance, promoting and de-
fending the reputation of the team or organiza-
tion, negotiating agreements, and coordinating
related activities. Other terms used to describe
this type of leadership responsibility include “pro-
moter,” “ambassador,” and “external coordinator.”
Leaders of project teams have more successful
projects when they have sufficient influence to
obtain essential resources and support from top
management (Katz & Allen, 1985). For work
units that have high interdependence with other
subunits of the organization or with outsiders such
as suppliers, clients, and distributors, it is impor-
tant for the leaders to coordinate activities, re-
solve disagreements, and buffer work-unit mem-
bers from interference (Ancona & Caldwell,
1992). Top executives need to influence external
stakeholders whose confidence and support are
important to the success and survival of the
organization (Fanelli & Misangyi, 2006). Repre-
senting also includes some political tactics that
can be used to influence decisions relevant for a
leader’s work unit or organization, but research on
the use of political tactics by leaders in organiza-
tions is still very limited. Evidence that represent-
ing is related to effective leadership is provided by
research using survey questionnaires (e.g., Ancona
& Caldwell, 1992; Dorfman, Howell, Cotton, &
Tate, 1992; Yukl, Wall, & Lepsinger, 1990), re-
search with incident diaries and interviews (e.g.,
Amabile et al., 2004; Ancona & Caldwell, 1992;
Campbell, Dunnette, Arvey, & Hellervik, 1973;
Druskat & Wheeler, 2003), and comparative case
studies (e.g., Ancona & Caldwell, 1992; Edmond-
son, 2003b; Kanter, 1983; Van Fleet &
Yukl, 1986).
Future Research
Much of the research on effects of leader be-
havior has examined how often the behavior
is used, but the effects also depend on other
conditions that are seldom considered. To im-
prove leadership theory and practice we need to
know more about how much the behaviors are
used, when they are used, how well they are used,
why they are used, who uses them, the context for
their use, and joint effects on different outcomes.
This part of the article explains the need for more
research on the quality and timing of behavior,
patterns of behavior, leader skills, leader values,
trade-offs for multiple outcomes, situational vari-
ables, the joint effects of multiple leaders, and the
joint effects of behavior and formal programs.
Quality and Timing of Behavior
Most leader behavior studies emphasize how much
the behavior is used rather than how well it is
used. Few studies have examined the quality and
timing of the behavior or checked the possibility
of a non-linear relationship between behavior and
the performance criterion. There is growing evi-
dence that most types of leadership behavior can
be overused as well as underused, and the optimal
amount of behavior is often a moderate amount
rather than the maximum amount (e.g., Fleish-
man & Harris, 1962; Gebert, Boerner, & Lan-
wehr, 2003; Pierce & Aguinis, in press). For ex-
ample, too much clarifying can limit innovation,
empowerment of subordinates, and development
of their problem-solving skills, but too much au-
tonomy can result in coordination problems,
lower efficiency, and inconsistent treatment of
clients. Even when doing more of a behavior
does not reduce the benefits or have negative side
effects, spending more time than necessary on a
behavior means that the leader is losing the op-
portunity to use more beneficial types of behavior.
2012 75Yukl
Timing is often a critical determinant of effec-
tiveness for a behavior, and acting too early or too
late can reduce the effectiveness of many behav-
iors. For example, taking action to avoid a prob-
lem or resolve it quickly is usually more effective
than waiting until the problem becomes very se-
rious and difficult to resolve. Praise for an achieve-
ment or contribution is usually more effective
when it is given promptly rather than waiting
months to mention it in a formal performance
review. Research is needed to identify optimal
levels of the behaviors and when the behaviors are
most likely to be effective.
Patterns of Behavior
In most research on the effects of leader behavior
the focus is on the independent effects of each
meta-category or individual behavior, but in many
cases the effects depend in part on what other
behaviors the leader uses. To understand why a
leader is effective requires that we examine how
different behaviors interact in a mutually consis-
tent way. The effective pattern of behavior may
involve multiple components of the same meta-
category or component behaviors from different
meta-categories. For example, monitoring opera-
tions is useful for discovering problems, but unless
something is done to solve the problems, moni-
toring will not contribute to leader effectiveness.
Monitoring is more effective when used together
with other behaviors such as problem solving,
coaching, and recognizing.
The descriptive research on effective leaders
suggests that they use complementary behaviors
woven together into a complex tapestry, and the
whole is greater than the sum of the parts (Kaplan,
1988). Similar results were found in research using
incident diaries from team members (Amabile et
al., 2004). The pattern of specific component
behaviors is usually more important than how
much each behavior is used, and more than one
pattern of behavior may be used to accomplish the
same outcome. Sometimes it is necessary for a
leader to find an appropriate balance for behaviors
that appear inconsistent, such as directing versus
empowering (Kaiser & Overfield, 2010). More
research is needed to determine how interacting
behaviors are used effectively by leaders in differ-
ent situations.
Multiple Outcomes and Trade-Offs
Each specific type of leadership behavior can in-
fluence more than one type of outcome or perfor-
mance determinant. For example, developing is
classified as a relations-oriented behavior because
the primary objective is usually to help people
improve their capabilities and advance their ca-
reers. But some types of developing are used to
improve performance in the current job (a task
objective) or facilitate the successful use of an
innovative new technology (a change objective).
Consulting with team members about the action
plan for a new project may increase member com-
mitment (human relations), improve the use of
available personnel and resources (efficiency), and
identify more innovative ways to satisfy clients
(adaptation).
Specific behaviors with positive outcomes for
more than one objective are desirable and can
increase a leader’s effectiveness. However, some
leader behaviors have unintended side effects that
are negative rather than positive. A behavior can
have positive effects for some outcomes and neg-
ative effects for other outcomes. For example,
delegating responsibility for determining how to
do a task to someone with little experience may
increase learning for the person, but it can reduce
short-term efficiency (e.g., more errors, slower task
completion, lower quality). Some decisions in-
tended to benefit employees (e.g., increasing pay
and benefits) may increase costs and reduce short-
term financial performance. Some decisions in-
tended to reduce costs can reduce human relations
and resources (i.e., downsizing can result in less
commitment for remaining employees and loss of
unique knowledge). Some decisions made to re-
duce costs (e.g., reducing research activities, out-
sourcing operations that involve unique knowl-
edge) can also reduce future adaptation. The
trade-offs for different outcomes are described by
leadership theories such as competing values the-
ory (Quinn & Rohrbaugh, 1983) and flexible
leadership theory (Yukl, 2008). More research is
needed to discover how effective leaders use spe-
cific behaviors that enhance multiple outcomes,
76 NovemberAcademy of Management Perspectives
minimize negative side effects, and balance diffi-
cult trade-offs.
Situational Variables
The effects of a leader’s behavior also depend on
the situation. Each meta-category includes behav-
iors that are often relevant for influencing perfor-
mance outcomes, but aspects of the situation de-
termine which component behaviors are relevant.
Effective leaders analyze the situation and identify
the specific behaviors that are relevant. The abil-
ity to use a wide range of specific behaviors and
adapt them to the situation is sometimes called
“behavioral flexibility,” and it is related to effec-
tive leadership (Hart & Quinn, 1993; Hooijberg,
1996; Yukl & Mahsud, 2010). Unfortunately,
most studies on situational moderator variables
have used behavior meta-categories, and the re-
sults are weaker and more difficult to interpret for
a broad category than for specific behaviors. For
example, the research testing contingency theo-
ries about the effects of task-oriented and rela-
tions-oriented behaviors failed to find strong, con-
sistent results (Podsakoff, MacKenzie, Ahearne, &
Bommer, 1995). There has been less research on
situational moderators for the other meta-catego-
ries, and there is little systematic research to iden-
tify situations where specific leadership behaviors
are most likely to impact performance outcomes.
More research is needed to learn how leaders
adapt their behavior to changing situations and to
assess the importance of behavioral flexibility for
different types of leaders. The common practice of
examining one situational variable at a time is less
useful than examining how the situational vari-
ables that define common situations for leaders
jointly determine which behaviors are most
relevant.
Leader Skills
Skills involve the ability to perform some type of
activity or task, and some studies on effective
leadership use skills rather than observable behav-
iors as the independent variables. Different tax-
onomies have been proposed for classifying skills,
and some scholars define them more broadly than
others. The early research identified three broadly
defined skills (Katz, 1955; Mann, 1965): Techni-
cal skills are primarily concerned with things, in-
terpersonal skills are primarily concerned with
people, and conceptual skills are primarily con-
cerned with ideas and concepts. Other types of
skills that have been used in leadership research
include political skills (Ferris, Treadway, Perrewé,
Brouer, Douglas, & Lux, 2007), administrative
skills, and competencies involving the ability to
use specific types of behavior such as planning and
coaching (e.g., Mumford, Campion, & Morgeson,
2007). Skills are not equivalent to actual behav-
ior, but they can help us understand why some
leaders are able to select relevant behaviors and
use them more effectively. A combination of skills
and traits can help to explain why some leaders
are able to recognize what pattern of behavior is
relevant, how much of each behavior is optimal,
and when to use the behaviors. The research on
how skills can enhance the effects of leader be-
havior is still very limited, and more studies are
needed to discover how a leader’s skills and per-
sonality traits influence the choice of behaviors
and leader flexibility in adapting behavior to dif-
ferent situations.
Leader Values and Integrity
The effects of the specific component behaviors
also depend on how much the leader is trusted by
people he or she wants to influence. Most types of
leadership behavior can be used in ethical or un-
ethical ways, and a leader who is not trusted will
have less influence. Leader values and integrity
did not get much attention in the early research
on effective leadership, but interest in them has
increased in recent years (Brown & Trevino,
2006). Values such as honesty, altruism, compas-
sion, fairness, courage, and humility are empha-
sized in servant leadership theory (Greenleaf,
1970), spiritual leadership theory (Fry, 2003), and
authentic leadership theory (Avolio, Gardner,
Walumbwa, Luthans, & Mayo, 2004; George,
2003). Proponents of these theories contend that
leaders whose behavior reflects these values will
be more effective. However, research on these
subjects is still very limited, and more studies are
needed to understand how leader values influence
the use of the specific behaviors and the effects of
the behaviors.

Multiple Leaders and Shared Leadership
Most of the research on the outcomes of leader-
ship behavior examines relationships only for in-
dividual leaders. However, organizations have
many leaders who can influence important deci-
sions and determine how successfully they are
implemented (Mintzberg, Raisinghani, & Theo-
ret, 1976; Schweiger, Anderson, & Locke, 1985).
Sometimes two or more leaders have shared re-
sponsibility for an activity or project, and some-
times leaders have different but interdependent
responsibilities. The performance of an organiza-
tion depends in part on the level of cooperation
and coordination among interdependent leaders
(Yukl, 2008; Yukl & Lepsinger, 2004). It is more
difficult to achieve a high level of cooperation
when the leaders do not share the same objectives
or have the same priorities. In some cases, one
leader’s actions to improve subunit performance
can be detrimental to the performance of other
subunits and the overall organization. For exam-
ple, a subunit leader may gain control of resources
that other subunits need and could use more ef-
fectively. Several scholars have discussed how
shared or distributed leadership is related to team
or organizational effectiveness (e.g., Brown &
Gioia, 2002; Carson, Tesluk, & Marrone, 2007;
Denis, Lamothe, & Langley, 2001; Friedrich,
Vessey, Schuelke, Ruark, & Mumford, 2009;
Pearce & Conger, 2003). However, more research
is needed to discover how the use of the specific
behaviors by different leaders can influence their
effectiveness.
Behaviors and Formal Programs
Management programs and systems can enhance
the effects of direct leadership behaviors. For ex-
ample, encouraging innovative thinking is more
likely to increase innovation when an organiza-
tion has a climate of psychological safety for risk
taking and appropriate rewards for creative ideas
about improving products and processes. Programs
and structures can also limit the use of leadership
behaviors or nullify their effects. For example, it is
difficult to empower subordinates when they must
follow elaborate rules and standard procedures for
doing the work. Management programs and sys-
tems can also serve as substitutes for some types of
direct behaviors. For example, company-wide
training programs for widely relevant skills can
reduce the amount of training that managers need
to give their immediate subordinates. Top execu-
tives have responsibility for implementing and
revising programs, and the effectiveness of pro-
grams depends on support by lower-level manag-
ers. The effects of leader behavior and manage-
ment programs have been examined separately,
but more systematic research is needed to examine
their joint and interacting effects on organiza-
tional performance.
Summary and Recommendations
The proposed hierarchical taxonomy facilitates
the integration of important findings in re-
search on leader behavior constructs and re-
search about the effects of specific behaviors on
team or organizational performance. More than
half a century of research provides support for the
conclusion that leaders can enhance the perfor-
mance of a team, work unit, or organization by
using a combination of specific task, relations,
change, and external behaviors that are relevant
for their situation. Why the behaviors are impor-
tant for effective leadership is explained better by
theories about the determinants of group and or-
ganizational performance than by leadership the-
ories focused on motivating individual followers.
A limitation of the conclusions about effective
leadership is that enhancing performance is not
the only basis for evaluating effectiveness, and the
importance accorded different criteria affects the
selection of relevant behaviors for a taxonomy.
The hierarchical taxonomy can be used to ex-
plain results found in the extensive research on
behavior meta-categories not used in the taxon-
omy, such as transformational and transactional
leadership. The results found in survey research on
transformational leadership can be explained as
effects of specific behaviors used to compute the
composite score for each leader (e.g., Yukl, 1999;
Yukl, O’Donnell, & Taber, 2009). Individualized
consideration includes supporting and develop-
ing, inspirational motivation includes envision-
ing change, and intellectual stimulation in-
cludes aspects of encouraging innovation.
78 NovemberAcademy of Management Perspectives
Idealized influence is primarily a measure of
perceived leader integrity involving consistency
between leader actions and espoused values.
Transactional leadership includes one task-ori-
ented behavior (monitoring), one relations-ori-
ented behavior (recognizing), and communica-
tion of reward contingencies, which are usually
specified by the formal compensation program.
The taxonomy described in this article
should not be viewed as the final solution for
classifying leadership behavior. Behavior con-
structs are conceptual tools, and there is no ob-
jective reality for them. They are most useful
when they can be measured accurately, they can
predict and explain leader influence on important
outcomes, and they can improve leadership devel-
opment programs. Future research may discover
additional component behaviors that should be
included (e.g., implementing change). Some com-
ponent behaviors may need to be expanded to
include forms of the behavior not explicitly in-
cluded in the current descriptions. Some of the
broader component behaviors in the current tax-
onomy may need to be subdivided in the future if
it is found that narrower components would pro-
vide a better explanation of leadership effective-
ness. However, at this time it does not appear
worthwhile to make the taxonomy any more com-
plex. The current version is easy to remember and
easy to use for developing an observation checklist
or a coding guide (the behavior definitions are
provided in the appendix).
Future research may also provide justification
for adding more meta-categories, and a possible
candidate is ethical and socially responsible lead-
ership. One component of this meta-category
could be leadership behavior that encourages eth-
ical practices. Some examples are communicating
ethical standards, encouraging ethical conduct,
modeling ethical behavior, and opposing unethi-
cal conduct. Another component could be lead-
ership behavior that encourages corporate social
responsibility. Examples include making decisions
that consider the needs of different stakeholders,
encouraging support of worthy community service
activities, encouraging improvements in product
safety, and recommending practices that reduce
harmful effects for the environment. Leadership
decisions and actions intended to benefit employ-
ees, customers, or the environment are controver-
sial if they do not also benefit the organization
(Cameron, 2011; Waldman, 2011; Waldman &
Siegel, 2008). Research on the effects of ethical
and responsible leadership is still very limited, and
more research is needed to identify relevant be-
haviors and assess their short-term and long-term
effects. The focus of this article is on leadership
behaviors intended to improve performance, and
more research is needed to determine if ethical
and responsible leadership should be included as a
separate meta-category in a taxonomy for describ-
ing performance-enhancing behaviors.
The hierarchical taxonomy provides a broad
perspective for understanding the types of behav-
ior that determine how effective a leader will be,
but the specific component behaviors are much
more useful than the meta-categories for develop-
ing better contingency theories and practical
guidelines for leaders. Moderator variables for
some of the specific behaviors have been suggested
(Yukl, 2013), but more research is needed on the
joint effects of situational variables. Other rele-
vant conditions that need more attention in fu-
ture research include non-linear relationships be-
tween behavior and outcomes, reciprocal
causality, lagged effects, effects for different out-
comes, effects of negative forms of the behaviors,
effects of different combinations of specific behav-
iors, mediating processes that explain why the
behaviors influence performance, the joint effects
of multiple leaders, multi-level effects of behav-
iors, and joint effects for behaviors and programs.
When designing future studies on leadership it
is important to select research methods that are
appropriate for the type of knowledge sought
rather than merely using a method that is familiar
or convenient. Each research method has limita-
tions, and it is desirable to use multiple methods
whenever feasible. Strong research methods
should be used more often, including longitudinal
field studies and experiments with manipulation
of leader behaviors in simulated teams or organi-
zations to assess immediate and delayed effects.
More studies should include incident diaries or
video recording of leaders. When behavior ques-
tionnaires are used, more effort should be made to
2012 79Yukl
improve measurement accuracy and minimize re-
spondent biases (e.g., train respondents to under-
stand and recognize the behaviors). If a survey is
conducted for a sample of homogeneous leaders
(e.g., project team managers, coaches of athletic
teams, public administrators), it should include
some behavior items that are directly relevant for
the sample rather than relying only on a behavior
questionnaire with generic examples. Leadership
effectiveness should be assessed from the perspec-
tive of multiple stakeholders and with multiple
criteria that include objective measures of work
unit or organizational performance.
Finally, it is important to recognize that observ-
able leadership behaviors are not the same as
skills, values, personality traits, or roles. These
other constructs can be useful for understanding
effective leadership, but they differ in important
ways from observable behaviors. When feasible,
future studies should investigate how the different
types of constructs jointly explain leader influence
on work unit performance and other outcomes.

... In a comprehensive factor analysis review of 'more than half a century of research' on leadership behaviour, Yukl (2012;p.78) identified four meta-categories of leadership. ...
... The four meta-categories encompass fifteen specific behaviours that were commonly found in the literature, as represented in Table 1: For this research, the participants' interview responses were analysed with reference to this taxonomy. There have been more recent systematic reviews of leadership literature (for example, see Mehrad et al., 2020;Deshwal & Ali, 2020;Gumus et al., 2018), but none of these more recent publications offer a taxonomy against which the data under review may be analysed, nor do their findings differ significantly than Yukl's (2012) findings. ...
... By assigning those codes to broader categories, common themes emerged, and by referring those themes back to the original data, the significance of each to the participants collectively and individually was carefully re-examined (Miles et al., 2018). The final stage of the process, the themes emergent from the data was compared to Yukl's (2012) taxonomy to identify the areas of salience and discrepancy which are outlined in the findings section below. ...

This article offers an interpretative reading of research interview data gathered with seven academics in a small English university that caters predominantly to widening participation students. The original interviews aimed to explore the most effective ways academics can support students in developing leadership capability. For this article, the author revisited the digital recordings of those original interviews and conducted an interpretive reanalysis of the data. This reanalysis aimed to ascertain the extent to which the conceptions of leadership that the academics hold align with the academic literature on the concept. Leadership is notoriously an ill-defined concept, and so, for this article, the author used Yukl’s (2012) taxonomy of leadership behaviours drawn from a systematic review of the literature as the basis for comparative analysis. The literature indicates that developing students’ leadership capability is a desirable educational outcome, but this presupposes that academics understand what the term leadership means. This article explores this by evaluating how well the academics' understanding of the concept of leadership aligned with the literature presented in Yukl’s (2012) taxonomy and considers the implications of this for their teaching. The article concludes with recommendations for adopting a coherent framework for academics to work within, especially for institutions that serve widening participation students. This article contributes to the knowledge of teaching practice by evaluating how well academics understand a concept they are (implicitly or explicitly) expected to teach and recommends further research to develop the scholarship.

Human factors are often linked to unsafe events in civil aviation transport, with the competency level and decision-making abilities of flight crews playing a significant role. The leadership and teamwork competency of the flight crew in the cockpit directly influences the occurrence of aviation safety incidents. Leadership is a developmental and trainable skill. This study aims to explore the key components of leadership and the competency model for civil aviation flight cadets. Based on classic leadership theories and leadership development theories, the research adopts a qualitative analysis using grounded theory and utilizes Nvivo 11.0 software for data analysis. An initial leadership evaluation index system for flight cadets was developed. Through a survey of 319 civil aviation pilots and using SPSS 26.0 software for data processing, an evaluation index system was established, covering 4 dimensions—core values, leader competency, outstanding thinking, and positive behavior—with 22 indicators. The study also applied AMOS 24.0 software to conduct validation factor analysis and path analysis and construct the BLVT model of leadership development for civil aviation flight cadets. The findings indicate that, within the 4 dimensions of leadership and the BLVT model, core values influence positive behavior through leader competency and outstanding thinking, resulting in appropriate performance by flight cadets. Outstanding thinking directly affects leader competency, thereby driving the leadership development of flight cadets, who form the development of their leadership skills by recognizing their leadership competencies. The results of this study clarify the 4 key elements of leadership composition and development for civil aviation flight cadets, providing valuable insights into leadership training and development. This study significantly contributes to bridging the gap in civil aviation pilot leadership training and offers a clear pathway for enhancing pilot leadership.
... Organizations have long been concerned with assessing the leadership ability and potential of their leaders and future leaders, hereafter "subordinate leaders" (Marshall-Mies et al., 2000). There have long been debates on which qualities make great leaders (Bass, 1985;Kirkpatrick & Locke, 1991) and limitations in the ability to accurately assess desired leadership skills and behaviors (Kolb, 1995;Yukl & = % of raters who said ratee being strong in this area leads to high raƟngs = % of raters who said ratee being weak in this area leads to low raƟngs Arrow displayed only if 20% or more of the leaders specifically menƟoned that criteria RF= RaƟng Factor= (% said strong leads to high raƟngs + % said weak leads to low raƟngs)/2 ...
... This selflessness is central to ethical and transformational leadership, where leaders act as role models, transforming followers' values and beliefs (Bass, 1999;Hendrix et al., 2015;Mayer et al., 2012). Yukl (2012) identifies task, relations, and change-oriented behaviors as key to organizational influence. Additionally, strong leader character links to greater organizational commitment, satisfaction, work group performance, and organizational citizenship behaviors (Hendrix, 2015). ...

This study investigates a paradox in leadership assessment, which we term the Leader Rating Gap (LRG). Through content analysis of interviews with 25 West Point cadets and tactical officers, we found that raters primarily cited influence behaviors when describing great leadership in general. However, when evaluating their own subordinate leaders’ job performance, raters emphasized individual performance behaviors over influence behaviors. These findings have implications for leadership development and assessment practices in military and civilian organizations, highlighting the need for organizations to align their leadership evaluation criteria with desired leadership behaviors and outcomes.
... Problem-solving is a task-oriented managerial behaviour (Yukl, 2012) and in line with Yukl, more studies are needed to discover how a leader's crea ve ability a ributes influence the choice and use of problem-solving behaviour. Crea vity, a desirable personality-oriented trait, is relevant in people's problems solving efforts (Lin, 2010). ...

The study examined the linkages between creative problem-solving ability attributes and the specific components of the institutional (corporate) brand personality dimensions; as well as the predictive influence of creative problem solving ability attributes on the aggregated institutional brand personality of Ghanaian basic schools. Two hundred and seventy-nine headteachers and 558 teachers provided data using the creative problem-solving ability attributes and brand personality dimensions inventories. The structural equation modelling result showed that the hypothesised model of the linkage between creative problem-solving ability attributes and institutional brand personality fit the data. Results also indicated that divergent thinking had a significant indirect effect on brand personality, with motivation and knowledge showing significant direct effects. The implication of the findings when it comes to school leaders creatively providing solutions and determining the schools brand personality was discussed.
... However, integrating all aspects of leadership behavior, leadership could be defined as "developing ideas and a vision, upholding that values support them, influencing others to adapt those values into their own actions and making difficult decisions about human and other resources. Further hierarchical taxonomy explains the types of leadership behaviors that impact an organizations teams or work unit performance [18]. There are four meta categories. ...

This study examines the impact of strategic leadership on organizational well-being, with external factors acting as a moderating influence, using the Sri Lanka Police as a case study. Strategic leadership plays a crucial role in fostering organizational success, particularly in complex and dynamic environments. The research explores key dimensions of strategic leadership, including alignment, decision-making and interpretation, and their effects on financial, social and human resource well-being. Additionally, external factors such as political, regulatory, technological, social, and cultural changes, as well as global crises, were analyzed to determine their moderating effect on the relationship between leadership and well-being. The study employed a quantitative research methodology, utilizing structural equation modeling through AMOS software to analyze the relationships among variables. Factor analysis confirmed the validity of measurement items, leading to the refinement of the dataset. The findings indicate a significant positive relationship between strategic leadership and organizational well-being, particularly in terms of social and human resource well-being. However, financial well-being did not show a statistically significant relationship with strategic leadership. Among external factors, political instability was found to have a negative moderating effect, whereas technological and social changes enhanced the relationship between strategic leadership and organizational well-being. Based on these findings, the study recommends strengthening leadership development programs, implementing participatory leadership approaches, and establishing structured frameworks to address external changes. Policymakers and law enforcement agencies can utilize these insights to refine leadership models and enhance organizational resilience.
... Organizational success demands leaders with a blend of commitment and enhanced leadership skills (Yukl 2012), because leadership is a pivotal factor in shaping organizational performance and achieving the intended learning outcomes. Scholarly investigations underscore the pivotal role of organizational commitment in shaping various organizational outcomes, including performance, absenteeism, turnover intentions, and positive citizenship behaviors, all of which bear direct implications for an organization's growth and success (Herrera and De Las Heras-Rosas 2021). ...

Abstract: The study aimed to assess the commitment levels of school leaders in the Sidama Regional State context with respect to enhancing the academic performance of secondary school students. Employing a concurrent embedded design, the research involved 163 teachers and 72 leaders selected from secondary schools using simple random and five supervisors through purposive sampling methods. The validity of data collection instruments was ensured by expert reviewers, and the reliability was checked through pilot testing (Cronbach alpha value = .827). Data collection utilized questionnaires, semi-structured interviews, and document analysis. One-sample t-tests analyzed questionnaire data, while thematic analysis provided insight into qualitative data. Results indicated that school principals show a moderate level of affective commitment to their roles and have better alternatives; they would consider leaving their positions, highlighting the crucial role of leadership commitment in improving students’ academic success and achieving school objectives. Additionally, the study identified challenges faced by principals, including inadequate resources, workload, external interference, limited experience, and low compensation, hindering their motivation to demonstrate the expected commitment levels. Consequently, the study suggests government intervention by providing sufficient financial resources, minimizing external interference, and implementing attractive incentive strategies to increase school leaders’ commitment toward enhancing students’ academic performance.

Purpose This study aims to examine how the leadership-as-practice (L-A-P) framework aligns with the socioeconomic approach to management (SEAM) to address complex organizational change. It explores how L-A-P’s emergent, relational leadership principles can be operationalized through SEAM’s participatory tools to foster sustainable and adaptive transformation. Design/methodology/approach A qualitative, comparative case study approach was used, focusing on SEAM interventions in higher education, performing arts and health care. Data was collected through interviews, participatory workshops, stakeholder feedback (mirror effect) and quantitative assessments (hidden cost calculations). Analysis included pattern matching and reflexive interpretation to link empirical evidence with theoretical constructs. Findings The study identifies six key L-A-P aspects – socially constructed leadership, contextual leadership, future-oriented leadership, navigating power dynamics, tool-mediated leadership and holistic and multilevel leadership. These were effectively operationalized through SEAM methods. The intervener emerged as a contextual leader by fostering trust, mediating tensions and tailoring strategies to specific organizational cultures, which enabled transformative outcomes across the three cases. Research limitations/implications The study is based on three cases within specific sectors, limiting generalizability. Future research should explore broader applications of L-A-P and SEAM integration in diverse organizational and cultural contexts and assess long-term impact. Practical implications The findings offer practical insights into how SEAM tools can be used to enact relational leadership, foster collaboration and address hidden costs. Organizations can leverage this integrated framework to drive context-sensitive, sustainable change by engaging employees and aligning socioeconomic goals. Social implications By promoting participatory leadership and transparency, the approach enhances employee engagement and well-being, contributing to inclusive and resilient organizational cultures. Originality/value This research bridges L-A-P’s theoretical principles with SEAM’s practical methodologies, providing a novel perspective on relational and context-sensitive leadership. It highlights how these frameworks complement each other to foster systemic and sustainable organizational change. The study contributes actionable insights for practitioners and enriches leadership and change management literature by showcasing the transformative potential of integrating L-A-P with SEAM.

The article focuses on the leadership skills required across organizational levels. Leadership skill requirements across organizational levels can be usefully described using a strataplex. The term 'strataplex' is derived from the term 'strata' which comes from the word 'stratify' meaning having a number of layers, levels, or classes in an organized system, and the term 'plex' which comes from the word complex, meaning divided into a specified number of parts. Thus, the term 'strataplex' captures the stratified and complex (composite) nature of the leadership skill requirement categories and their relationship with level in the organization. The leadership skills required at various organizational levels can be understood in terms of four general categories: Basic leadership skills, supervisory leadership skills, managerial leadership skills, and executive leadership skills. There are several hypotheses implicit in the leadership skill requirement strataplex. First, it suggests that basic leadership skills are the most fundamental of the leadership skills. Leadership skill requirements will vary by skill type such that basic leadership skill requirements will be the highest, followed by supervisory, managerial, and executive leadership skills respectively. The second hypothesis states that overall leadership skill requirements will be positively related to job level.
