When unexpected events occur, IT project teams need to react appropriately in order to limit the potentially negative, and sometimes disastrous consequences of such events. Yet, while past research has identified unexpected events as being an important aspect to consider when managing projects, the existing literature does not provide a clear conce...

Purpose To help reduce the increasing number of information security breaches that are caused by insiders, past research has examined employee non-compliance with information security policy. However, existent studies have observed mixed results, which suggest that an interaction is likely to exist among the variables that explain employee non-comp...

en The objective of the present paper is to identify and develop a framework of IS habits that individuals tend to develop in organizational contexts. Based on Duhigg's (2012) framework of habit, the paper develops a new conceptualization of IS habit as a cue–routine–reward loop. The key difference between the proposed conceptualization and those t...

Purpose The purpose of this paper is to introduce activity theory (AT) as a new theoretical lens to the field of information security non-compliance by explaining how research in that field can benefit from AT and to suggest eight propositions for future research. Design/methodology/approach Based on AT, the paper suggests that employees, IT syste...

Researchers and practitioners have long been interested in identifying the criteria that users consider important in assessing whether a system is worth using. However, past research in this domain has not taken into account the characteristics of a system's design and their quality in a systematic and comprehensive manner, which is likely to have...

Purpose The purpose of this paper is to develop a clear and generalizable conceptualization of project team momentum, as well as a detailed and engaging research agenda on this concept. Design/methodology/approach A literature review was conducted to achieve the study’s objectives. The review acknowledges the meanings that researchers in the field...

While meetings are a frequently used management tool, they also tend to be costly and less effective than desired. Multicommunication in meetings (Meeting MC)—being simultaneously engaged both in an organizational meeting and in one or more technology-mediated secondary conversations—has become increasingly prevalent and can affect meeting outcomes...

Empirical Research in Information Systems: 2001-2015 provides a first step in providing empirical evidence and knowledge about the practical relevance of IS research. The monograph first develops a broad yet sufficiently fine-grained framework of IS research by integrating earlier frameworks. It then identifies all empirical IS research published f...

The present study examined how patients’ emotional responses to a Portal (i.e., a patient-centric health IT designed to help patients self-manage their chronic condition) influenced their effective use of the Portal. Based on interview data collected from 34 asthma patients, we identified six categories of emotions that the Portal’s usage evoked in...

Multicommunicating (MC) represents a form of multitasking in which employees such as IS analysts and managers engage in multiple conversations at the same time (e.g., by sending texts while on a telephone call). MC can occur either during group meetings or during one-on-one conversations: the present paper focuses on the latter, termed dyadic MC. M...

Information system development (ISD) projects are knowledge-intensive settings that involve varying levels of uncertainty and equivocality. The objective of the present paper is to better understand how project managers can enhance ISD project performance by adapting their level of interactive use of a project's control system (PCS) to the project'...

Social network sites (SNS) are venues for information sharing that provide a variety of communication features capable of stirring emotions, attitudes and beliefs. This paper highlights the role of SNS feedback features and the meanings they communicate to their users, as design elements capable of enhancing the SNS experience. Based on the theorie...

Although ability, benevolence, and integrity are generally recognized to be three key characteristics of trustworthiness that explain much of the within-truster variation in trustworthiness, some researchers have noted conceptual issues regarding how these characteristics are related to trust and have detected empirical inconsistencies in past rese...

Social network sites (SNS) have increasingly become widely used technologies that are well integrated in the daily routines of many individuals. As venues for information sharing, SNS provide a diversity of communication capabilities and feedback features that can stir emotions, attitudes, beliefs, as well as influencing many decisions. In this pap...

Privacy is a highly dynamic concept and individuals with distinct life experiences and knowledge can perceive it differently. Despite the advances made by past IS research, little is still known about the antecedents of Privacy Concerns Related to IT (PCIT), their formation, and the relationship between general PCIT and PCIT regarding specific tech...

Adopting an alternative, yet complimentary view to the traditional, performance-based task/technology fit perspective, we examine the post-adoption of social network sites (SNS) by extending the concept of IT desirability as a central predictor of SNS continuous-use. We conceptualize SNS desirability as reflecting the affective relationship individ...

Unexpected events occur during many IT projects and need to be adequately addressed so that their potentially negative impacts can be mitigated. While various tools and methodologies are available to help IT project teams better manage projects, our knowledge of unexpected events remains limited. To better understand such events, their impacts, and...

Assurance has different meanings, depending on the source, audience, and interpretation. We applied institutional theory and the Capability Maturity Model to conceptualize assurance: its symbolic aspects to gain social acceptance, and its substantive aspects to improve organizational capability and effectiveness in performing IS security risk manag...

We attempted to determine how formal management control systems (MCS) are used by project managers in IS development (ISD) contexts. This involved investigating the antecedents of two types of project MCS use (interactive and diagnostic), and their direct and moderated impact on project performance. PLS analysis of data collected in a survey of 93...

Information system (IS) researchers have long noted that IS analysts need to understand users' needs if they are to design better systems and improve project outcomes. While researchers agree that analyst communication activities are an important prerequisite for such an understanding, little is known about the nature of different communication beh...

Continuous-use, a key post-adoption behavior, has been typically explored based on adoption theories, portraying individuals as rational actors whose decisions are driven by intentions. Yet, continuous-use may not always be shaped by conscious rationality as emotions have been suggested to directly influence post-adoption and to overcome the format...

Although habit and intention have both been used to explain post-adoptive behaviors in IS acceptance research, their relationship remains unclear. The present paper provides definitions for the two constructs, identifies their differences and similarities, and hypothesizes that the correlation between the two constructs is stronger for non-reflecti...

Drawing on the concept of organizational integration, we developed a typology that allows us to classify organizational IT applications and better understand, explain, and potentially predict their impacts. As a preliminary test of the typology, the empirical evidence of past research on the impacts of IT on organizational performance was reviewed....

An important factor that can influence the user-analyst relationship during information systems development is how analysts communicate with users. The present study examines the extent to which analyst multicommunicating behaviors during meetings with users influence perceptions of the analyst and willingness to help the analyst with subsequent ta...

This paper examines user participation in information systems security risk management and its influence in the context of regulatory compliance via a multi-method study at the organizational level. First, eleven informants across five organizations were interviewed to gain an understanding of the types of activities and security controls in which...

Empirical results both from information technology acceptance research as well as from other fields suggest that attitude and subjective norms may have a nonlinear relationship. Based on the economic theory of complementarities, the present paper hypothesizes a substitution relationship or negative synergy between attitude and subjective norms in o...

Conceptualization and measurement of constructs provide many opportunities for contributing to information systems research and practice by providing a better understanding and explanation of interesting and important phenomena. To assist researchers in such endeavors, this paper describes four approaches to construct conceptualization and illustra...

The present paper proposes psychological ownership of IT (POIT) as a construct that can provide a much needed linkage between the IT implementation and IT acceptance research streams. To assess this idea, a research model was developed where POIT was hypothesized to mediate the influence of user participation on perceived usefulness (PU) and percei...

Despite increased research interest on e-government, the field currently lacks sound theoretical frameworks that can be useful in addressing two key issues concerning the implementation of e-government systems: (1) a better understanding of the factors influencing the adoption of e-government systems, and (2) the integration of various e-government...

Research has shown that some groups using electronic brainstorming generate more unique ideas than groups using nominal group brainstorming, while others do not. This study examined two factors through which group size may affect brainstorming performance: synergy and social loafing. Groups brainstormed using three techniques to manipulate synergy...

Conceptualizing e-government at the level of municipalities, the objective of this research is to provide a conceptual and methodological framework to understand and measure the linear and non-linear relationships that exist between the different factors affecting e-government acceptance, use and impact. It aims at empirically showing why some loca...

Despite calls for improving current approaches to conceptualizing and measuring the construct of information system use, theoretical advances in this regard are still insufficient. The present paper proposes to expand the focus of existing conceptualizations that exclusively focus on technology interaction behaviors via the construct of IS use-rela...

The Technology Acceptance model (TAM) is one of the most influential theories in Information Systems. However, despite the model's significant contributions, the intense focus on TAM has diverted researchers’ attention away from other important research issues and has created an illusion of progress in knowledge accumulation. Furthermore, the indep...

Despite increased research interest on e-government, existing research has not adequately addressed two key issues concerning the implementation and integration of e-government systems: a better understanding of the factors influencing the adoption and acceptance of e-government systems, and a better understanding of the factors that influence the...

Previous research has shown that some groups using electronic brainstorming generate more unique ideas than groups using nominal group brainstorming, while others do not. This study examined two factors through which group size may affect brainstorming performance: synergy and social loafing. Groups brainstormed using three techniques to manipulate...

This paper reports on an ongoing research project on intranet usability. Intranets are web-based information systems that are thought to boost employee productivity and improve organizational performance. For its part, usability is considered to be a key factor that influences the quality of computer-human interactions. The objective of the researc...

Past research on IT acceptance and use has largely focused on relationships between constructs in models that are based on a small number of overlapping theoretical frameworks, and has neglected to integratively examine the IT artifact-related antecedents of these models’ constructs. The present paper addresses this issue by incorporating into the...

The implementation of information systems in organizations is a long standing research topic that has preoccupied researchers ever since computer-based information systems started being used in businesses in the early 1960s. However, despite more than 40 years of research, the implementation phenomenon continues to present both practical and resear...

The notion of integration is central to the understanding of organizations in general as well as of contemporary phenomena such as e-commerce, virtual organizations, virtual teams, and enterprise resource planning (ERP) implementation. Yet, the concept of integration is ill-defined in the literature, and the impact of achieving high levels of integ...

Many ERP implementations fail to achieve their hoped-for benefits and require investments that are often much larger than originally estimated. There is also a need to progress toward more theoretically grounded ERP implementation research. The present paper constitutes a step in that direction and proposes a conceptualization of ERP implementation...

The lack of a clear conceptualization and operationalization of the construct of interpersonal conflict makes it difficult to compare the results of different studies and hinders the accumulation of knowledge in the conflict domain. Defining interpersonal conflict as a dynamic process that occurs between interdependent parties as they experience ne...

Notwithstanding the domain of activities where they are conducted, projects often entail risks, and risk management has been widely recognized as a success factor in project management. While several lists of risk factors have been proposed in several domains, there exists no generic tool for helping the assessment of the risk level of a given proj...

Researchers in Organization Theory have suggested that the way an organization, business unit or department is managed should vary according to the uncertainty inherent in its environment.

In a recent commentary, Dennis and Valacich (1999) raise several issues concerning the effectiveness of electronic brainstorming (EBS) and conclude that, when brainstorming groups contain more than eight individuals, EBS technology is more effective than nominal brainstorming. The present paper offers several theoretical and empirical reasons to ju...

While the construct of IS use is a key research variable in IS, its past conceptualizations and measurement have important shortcomings. The present paper proposes a behavioral and perceptual framework that can be used to provide a more fine grained and richer conceptualization of the IS use construct.

Organizational theories often rely on notions of coordination, interdependence, and responsiveness to analyze how business processes and units depend on each other and contribute to organizational performance. Defined as the responsiveness of the distinct processes and technologies of the entire value chain of an organization, the construct of orga...

Few conflict researchers clearly specify, not only their chosen definitions and means of assessing interpersonal conflict, but also how their conceptualization is similar or different from other researchers' perspectives. The lack of a clear conceptualization and operationalization of the construct of interpersonal conflict makes it difficult to co...

Many ERP implementations fail to achieve their hoped-for benefits and efforts invested in ERP implementations are often much larger than originally estimated. In addition, research on ERP implementation is still in its early stages and needs to be grounded in theory. To provide a theoretical foundation for ERP implementation research, the present p...

Despite more than sixty years of research, the construct of interpersonal conflict remains relatively poorly defined and measured which significantly hinders the accumulation of knowledge in the conflict domain. The present paper addresses this issue by proposing a general definition for the construct of interpersonal conflict, as well as a two-dim...

Researchers from a wide range of management areas agree that conflicts are an important part of organizational life and that their study is important. Yet, interpersonal conflict is a neglected topic in information system development (ISD). Based on definitional properties of interpersonal conflict identified in the management and organizational be...

Idea quality is the most important indicator of group brainstorming performance. Yet, little electronic brainstorming (EBS) research has assessed idea quality directly. This article provides a closer look at EBS and nominal brainstorming groups in terms of idea quality. This study employed an unbalanced repeated measures experimental design to comp...

User participation is defined as the extent to which users or their representatives carry out assignments and perform various activities and behaviors during the system development process. This work has identified three dimensions of user participation: responsibility, the user-IS (information system) relationship and hands-on activity. However, t...

Drawing both from the IS literature on software project risk management and the contingency research in Organization Theory literature, the present study develops an integrative contingency model of software project risk management. Adopting a profile deviation perspective of fit, the outcome of a software development project (Performance) is hypot...

A After discussing how group size might affect the effectiveness of electronic brainstorming (EBS) as an idea generating tool, Dennis and Valacich (1999) conclude that EBS is not likely to surpass nominal brainstorming for small groups, but that for large groups (i.e., nine or more members), "EBS offers clear performance benefits over nominal group...

Electronic brainstorming (EBS) has been proposed as a superior approach to both nominal brainstorming (working alone) and face-to-face brainstorming (verbal). However, existing empirical evidence regarding EBS's superiority over nominal brainstorming is weak. Through a comprehensive examination of the process gains and process losses inherent to di...

The topics of conflict and conflict resolution are important to an understanding of the information system development (ISD) process. The present paper explores conflict management behaviors and relates their use to the satisfactory resolution of conflicts in ISD. Project-level scores representing users' and analysts' typical modes of behavior were...

This case describes the implementation of the payroll and human resources modules of an integrated software product in a large manufacturing organization.

User participation has long been considered a key ingredient in information system development (ISD). However, research has generally failed to clearly demonstrate the benefits of user participation. A better description of interpersonal processes which occur during system development could be used to help explain the weak results. The present stud...

Even though user participation in information system development has long been considered to be a critical factor in achieving system success, research has failed to clearly demonstrate its benefits. This paper proposes user involvement as an intervening variable between user participation and system use. Embedding the constructs of participation a...

Defining user participation as the activities performed by users during systems development, user involvement as the importance and personal relevance of a system to its user, and user attitude as the affective evaluation of a system by the user, this study aims to: (1) develop separate measures of user participation, user involvement, and user att...

Despite the introduction and use of a wide variety of system development methods and tools, software projects are still plagued by time and cost overruns, and unmet user requirements. To avoid these problems, it is frequently recommended that the risk associated with a software project be managed. A task that is critical to the proper management of...

Defining user participation as the activities performed by users during system development and user involvement as the importance and personal relevance of a system to its user, the authors examine the empirical relationship of participation and involvement with system usage. Based on a field survey of 74 users of management support systems and 31...

This paper reports the results of a field study of 32 decision support systems (DSS) in 9 organizations that was conducted to examine the effects of certain factors which influence DSS implementation success.

Attribution, expectation, disconfirmation and performance effects are suggested as possible determinants of user satisfaction judgements relating to information systems and their relationship is investigated in a field study. The results indicate that while all four factors are significant in explaining judgments of user satisfaction with informati...

Within the field of information systems, user involvement generally refers to participation in the systems development process by potential users of their representatives and is measured as a set of behaviors or activities that such individuals perform. This article argues for a separation of the constructs of user participation (a set of behaviors...

Information systems researchers, while helping others build better information systems, have done little in supporting their own information needs. The large amount of knowledge accumulated in IS today has created a situation where the researcher needs some sort of organizing mechanism to map the IS territory and relate its different components. A...

It is generally recognized that user attitudes are important determinants of success in the implementation of information systems. Among these, users' attitudes towards the changes introduced by a system are thought to be especially important in the implementation of MIS and OR/MS applications. Based on the results of a survey of 32 decision suppor...

Research on implementation of computer‐based information systems has now reached a stage where in‐depth investigations of the relationships and contingencies between variables influencing the eventual “success'' of a system, have become possible. This paper proposes a research framework for studying the contingencies between variables influencing t...
