Wicked
Problems
in
Design
Thinking
Introduction
Despite
efforts to discover
the foundations
of design
thinking
in
the fine arts,
the natural
sciences,
or most recently,
the social
sci-
ences, design
eludes reduction and
remains
a surprisingly
flexible
activity. No single definition of design, or branches of profes-
sionalized
practice such as
industrial or graphic design,
adequately
covers the
diversity
of ideas and methods
gathered together
under
the label.
Indeed,
the variety
of research
reported
in conference
papers, journal
articles, and
books suggests
that
design
continues
to expand
in its meanings
and connections,
revealing unexpected
dimensions
in practice
as well as understanding.
This follows the
trend of design thinking
in the
twentieth
century,
for
we have seen
design grow
from
a trade
activity
to a
segmentedprofession
to afield
for technical research and to what
now should be recognized
as a
new liberal
art of technological
culture.
It may seem
unusual to talk about
design
as a liberal
art,
par-
ticularly when many people are accustomed to identifying the
liberal arts with the traditional "arts
and sciences" that are
insti-
tutionalized
in colleges and universities. But the liberal arts
are
undergoing
a revolutionary transformation
in twentieth-century
culture,
and
design
is one of the
areas
in which
this
transformation
is strikingly
evident.
To understand the change that is now underway,
it is important
to recognize
that what are
commonly regarded as the liberal
arts
today
are
not
outside
of history. They
originated
in the
Renaissance
and underwent
prolonged
development that culminated
in
the
nine-
teenth
century
as a vision of an
encyclopedic education of beaux
arts,
belles
lettres,
history,
various
natural
sciences
and mathematics,
phi-
losophy, and
the fledgling social
sciences. This circle of learning
was divided into particular subject
matters, each with a proper
method
or set of methods suitable to its exploration. At their
peak
as liberal
arts,
these
subject
matters
provided
an
integrated under-
standing
of human experience and the
array of available
knowledge.
By the end of the nineteenth
century, however, existing
subjects
were
explored with progressively
more refined methods, and
new
subjects
were added to accord
with advances
in knowledge.
As a
This essay is based on a paper
presented
at
'Colloque Recherches sur le Design:
Incitations, Implications, Interactions,"
the
first French university symposium on
design research held October 1990 at
l'Universit6 de Technologie
de Compiegne,
Compiegne, France.
Design Issues: Vol. VIII, Number 2 Spring 1992 5
result,
the circle
of learning
was further
divided
and subdivided,
until
all
that remained
was a patchwork
quilt
of specializations.
Today,
these
subject
matters
retain
an echo of their
old status
as
liberal
arts,
but
they
flourish
as
specialized
studies,
leading
to the
perception
of an ever
more
rich
and detailed
array
of facts
and
val-
ues.
Although
these
subjects
contribute
to the advance
of knowledge,
they
also
contribute
to its
fragmentation,
as they
have become
pro-
gressively narrow in scope, more numerous, and have lost
"connection
with each
other
and
with the common
problems
and
matters
of daily life from which they select aspects
for precise
methodological
analysis."
The search
for new integrative
disci-
plines
to complement
the arts
and
sciences
has
become
one of the
central
themes
of intellectual
and practical
life
in the
twentieth
cen-
tury. Without integrative disciplines of understanding,
communication,
and
action,
there
is little
hope
of sensibly
extend-
ing knowledge
beyond
the library
or laboratory
in order
to serve
the
purpose
of enriching
human
life.
The emergence
of design
thinking
in the twentieth
century
is
important
in this context.
The significance
of seeking
a scientific
basis
for design
does
not lie in the likelihood
of reducing
design
to
one or another
of the sciences-an
extension
of the neo-positivist
project
and
still presented
in these
terms
by some
design
theorists
2
Rather,
it lies in a concern
to connect
and
integrate
useful
knowl-
edge
from the arts
and sciences
alike,
but in ways that are
suited
to the problems
and
purposes
of the present.
Designers,
are
explor-
ing concrete
integrations
of knowledge
that
will combine
theory
with practice
for new productive
purposes,
and
this is the reason
why we turn
to design
thinking
for
insight
into
the
new liberal
arts
of technological
culture3
Design and Intentional Operations
The beginning
of the study
of design
as a liberal
art can
be traced
to the
cultural upheaval
that
occurred
in the early
part
of the
twen-
tieth century.
The key feature
of this upheaval
was described
by
John
Dewey in The
Questfor
Certainty
as
the
perception
of a
new
center
of the universe.
The old
center
of the
universe
was the
mind
knowing
by.
means
of an
equipment
of
powers
complete
within
itself,
and
merely
exercised upon
an
antecedent
external
mate-
rial
equally
complete
within itself.
The new center
is
indefinite
interactions
taking
place
within a course
of
nature
which
is
not
fixed and
complete,
but
which
is
capa-
ble of direction
to new
and
different
results
through
the
mediation
of intentional
operations.'
What Dewey describes
here
is the root of the difference
between
the
old and
new liberal
arts,
between
specialization
in the
facts
of a
subject
matter
and
the
use of new
disciplines
of integrative
thinking.

2) Neo-positivism,
pragmatism,
and
var-
ious forms
of phenomenology
have
strongly
influenced
design
education
and practice
in the
twentieth
century.
If design theory has often tended
toward
neo-positivism,
design
prac-
tice has tended
toward
pragmatism
and pluralism,
with
phenomenologists
in both
areas.
Such
philosophical
dif-
ferences
are
illustrated
in
the
split
that
developed
between
the
theoretical
and
studio
courses
at the
Hochschule
fur
Gestaltung
(HfG)
Ulm before
its clos-
ing. The split between theory and
practice
in
design
is an
echo
of the
dif-
ference
between
the predominantly
neo-positivist
philosophy
of science
and
the exceptionally
diverse
philoso-
phies
of practicing
scientists.

history,
theory,
and criticism

to the
pluralism
of views that
guide
actual
design practice.
3) Walter
Groupius
was one of the
first to
recognize
the beginnings
of a new
lib-
eral
art
in design.
In an
essay
written
in 1937,
he reflected
on the
founding
of the Bauhaus as an institution
grounded
on the idea
of an architec-
tonic art: "Thus
the Bauhaus
was
inaugurated
in 1919
with the
specific
object
of realizing
a modern
architec-
tonic
art,
which
like
human
nature
was
meant
to be
all-embracing
in
its scope.
. . . Our guiding
principle
was that
design
is neither
an intellectual
nor
a
material
affair,
but
simply
an
integral
part
of the stuff
of life,
necessary
for
everyone
in
a
civilized
society."
Scope
of Total Architecture
(New York:
Collier Books,
1970),
19-20.
The
term
"architectonic,"
in this
case,
transcends
the derivative
term "architecture"
as
it is commonly
used in the modern
world.
Throughout
Western
culture,
the liberal arts have similarly
been
described
as "architectonic"
because
of their integrative
capacity.
Groupius
appeared
to understand
that
architec-
ture,
regarded
as
a liberal
art
in its own
right
in the ancient
world,
was only
one manifestation
of the
architecton-
ic art of design in the twentieth
century.

Dewey,
The
Quest
for
Certainty:
A Study
of the
Relation
of Knowledge
and Action (1929;
rpt. New York:
Capricorn
Books,
1960),
290-91.

Dewey observes,
however,
that
the meaning
and
implications
of the new direction
are
still
not fully understood.
Nowadays
we have
a
messy conjunction
of notions
that
are consistent
neither with one another
nor with the
tenor of our actual life.
Knowledge
is still
regarded by
most
thinkers
as direct
grasp
of ultimate
reality,
although
the
practice
of knowing
has been
assimilated
to the
pro-
cedure of the useful
arts;-involving,
that
is to say, doing
that
manipulates and
arranges
natural
energies.
Again
while science is said to lay hold of reality,
yet "art"
instead of being
assigned
a
lower
rank is equally
esteemed
and honored.
Carrying
these observations
further,
Dewey explores
the new
rela-
tionship
between
science, art,
and
practice.
He suggests
in
Experience
and Nature
that
knowledge
is no longer
achieved
by direct con-
formity of ideas with the fixed orders
of nature;
knowledge
is
achieved
by a new kind of art directed
toward orders of change.
But if modern tendencies are
justified
in
putting
art and
creation
first, then the implications
of this position
should be avowed and
carried
through.
It would then
be seen that science
is an art, that art is practice,
and
that the
only distinction
worth
drawing
is not between
practice
and
theory,
but
between those modes of prac-
tice that are not intelligent, not inherently and
immediately
enjoyable, and those which are full of
enjoyed
meanings.
Although the neo-positivists
courted
Dewey for a time,
it was
apparent
that his understanding of the development of science
in
the twentieth
century
was quite
different
from their
understand-
ing7.
Instead
of treating science
as primary and
art as secondary,
Dewey pointed
toward
science as art.
The
consideration
that
completes
the
ground
for assim-
ilating science to art is the fact that assignment of
scientific
status
in any given case
rests
upon facts which
are
experimentally produced.
Science
is now the
prod-
uct
of operations
deliberately
undertaken
in conformity
with
a plan or
project that
has the
properties of a work-
ing hypothesis.
What
Dewey
means
by "art"
in this
context
is crucial
to understand-
ing the new
role of design and
technology in contemporary
culture.
After a
period
in
which
natural
knowledge
progressed by
borrowing
from the
industrial
crafts,
science
entered upon
a
period
of steady
and
ever-accelerated
growth
by means
of deliberate
invention of such appliances on its own
account.
In
order to mark this
differential feature
of the art
which is science,
I shall
now use the
word
"technology."
... Because
of
technologies,
a
circular
relationship between
the
arts
of production
and
science has
been
established.

What Dewey defines as technology is not what is commonly
understood
in today's philosophy of technology.
Instead of mean-
ing knowledge
of how to make and use artifacts or the artifacts
themselves,
technology for Dewey is an art of experimental think-
ing. It is, in fact,
intentional operations
themselves carried out in
the
sciences, the
arts of production," or social
and political action.
We mistakenly
identify technology with one particular type of
product-hardware-that may result from experimental think-
ing,
but
overlook
the art that lies behind and
provides the basis for
creating other
types of products.
From this
perspective, it is easy to understand why design and
design thinking continue to expand their
meanings and connec-
tions in contemporary culture. There is no area
of contemporary
life
where design-the plan, project,
or
working
hypothesis which
constitutes the "intention"
in intentional
operations-is not a sig-
nificant factor in shaping human experience.
Design even extends
into the core of traditional scientific
activities,
where it is employed
to cultivate the subject matters that are the focus of scientific
curiosity. But perceiving
the existence of such an art
only opens
the door to further
inquiry, to explain
what that art is, how it
operates,
and
why it succeeds or fails
in particular
situations. The
challenge
is to gain
a deeper understanding
of design thinking
so
that more cooperation
and mutual benefit is possible between
those who apply
design thinking
to remarkably
different
problems
and
subject
matters. This will
help
to make the
practical
exploration
of design,
particularly in the arts of production,
more intelligent
and
meaningful.
However,
a persistent
problem
in this
regard
is that discussions
between
designers
and members
of the scientific
community
tend
to leave little room for reflection on the broader nature of design
and its relation to the arts and
sciences, industry
and manufactur-
ing, marketing and
distribution, and
the
general public
that
ultimately
uses the results of design thinking.
Instead of yielding productive
integrations,
the
result
is often confusion and a breakdown
of com-
munication,
with a lack of intelligent practice
to carry
innovative
ideas into
objective,
concrete embodiment.
In
turn,
this undermines
efforts to reach a clearer
understanding
of design
itself,
sometimes
driving designers
back into a defense of their work in the context
of traditional
arts
and
crafts.
Without
appropriate
reflection
to help
clarify
the
basis
of communication
among
all the
participants,
there
is little
hope
of understanding
the
foundations and
value of design
thinking
in an
increasingly complex technological
culture.

vative application.
Perhaps
this is what Herbert Simon meant in The
Sciences
of the Artificial, one of the major works of design theory
in the twentieth century, when he wrote: "the proper study of
mankind is the science of design, not only as the professional com-
ponent of a technical education but as a core discipline for every
liberally
educated
man."" One may reasonably
disagree
with aspects
of Simon's positivist and empiricist view of design as a science
(as one may disagree
with the pragmatic
principles
that stand
behind
Dewey's observation of the importance of intentional operations
in modern culture),"3
but there is little reason to disagree with the
idea that all men and women may benefit from an early under-
standing of the disciplines of design in the contemporary world.
The beginning of such an understanding has already turned the
study of the traditional arts and sciences toward a new engage-
ment with the problems of everyday experience, evident in the
development of diverse new products which incorporate knowl-
edge from many fields of specialized inquiry.
To gain some idea of how extensively design affects contem-
porary
life, consider the four broad
areas
in which design is explored
throughout the world by professional designers and by many oth-
ers who may not regard
themselves as designers. The first of these
areas is the design of symbolic and visual communications. This
includes the traditional work of graphic design, such as typogra-
phy and advertising,
book and magazine
production, and scientific
illustration, but has expanded into communication through pho-
tography, film, television, and computer display. The area of
communications design is rapidly evolving into a broad explo-
ration of the problems of communicating information, ideas, and
arguments through a new synthesis of words and images that is
transforming the "bookish culture" of the past.'4
The second area is the design of material objects.
This includes
traditional concern for the form and visual appearance
of everyday
products-clothing, domestic objects, tools, instruments, machin-
ery, and vehicles-but has expanded into a more thorough and
diverse interpretation of the physical, psychological, social, and
cultural
relationships
between products
and human beings.
This area
is rapidly evolving into an exploration of the problems of con-
struction in which form and visual appearance
must carry a deeper,
more integrative argument that unites aspects of art, engineering
and natural science, and the human sciences. 5
The third area
is the design of activities and organized services,
which includes the traditional management concern for logistics,
combining physical resources,
instrumentalities,
and human beings
in efficient sequences and schedules to reach specified objectives.
However, this area has expanded into a concern for logical deci-
sion making and strategic planning and is rapidly evolving into an
exploration of how better design thinking can contribute to achiev-
ing an organic
flow of experience
in concrete
situations,
making
such

Although
Simon's
The Sciences

is cited repeatedly
in
design
literature
because
of its definition
of
design,
it is often read
with little
atten-
tion given to the full argument.
A
careful
analysis
from the standpoint
of industrial design
would
be a use-
ful contribution
to the
literature.
Such
a reading
would
reveal the positivist
features
of Simon's
approach
and
help
to explain
why many
designers
are
somewhat disenchanted with the
book. Nonetheless, it remains
an
exceptionally
useful work.

of material

includes,

work in materials sci-
ence,
where

focused form of

thinking
is evident.

experiences more intelligent, meaningful, and satisfying. The cen-
tral theme of this area
is connections and consequences. Designers
are exploring a progressively wider range of connections in every-
day experience and how different types of connections affect the
structure of action.'6
The fourth area is the design of complex systems or environ-
ments for living, working, playing, and learning. This includes the
traditional
concerns of systems engineering, architecture, and urban
planning or the functional analysis of the parts of complex wholes
and their subsequent integration in hierarchies. But this area has
also expanded and reflects more consciousness of the central idea,
thought, or value that expresses the unity of any balanced and func-
tioning whole. This area
is more and more concerned with exploring
the role of design in sustaining, developing, and integrating
human
beings into broader ecological and cultural environments, shaping
these environments when desirable and possible or adapting to
them when necessary.
Reflecting on this list of the areas
of design thinking, it is tempt-
ing to identify and limit specific design professions within each
area-graphic designers with communication, industrial
designers
and engineers
with material
objects, designers-cum-managers
with
activities and
services,
and
architects and urban
planners
with systems
and environments. But this would not be adequate,
because these
areas are not simply categories of objects that reflect the results of
design. Properly understood and used, they are
also
places of inven-
tion shared
by all
designers, places
where one discovers the dimensions
of design thinking by a reconsideration
of problems and solutions.
True, these four areas
point toward certain kinds of objectivi-
ty in human experience, and the work of designers in each of these
areas has created a framework for human experience in contem-
porary culture. But these areas are also interconnected, with no
priority given to any single one. For example,
the sequence of signs,
things, actions, and thought could be regarded as an ascent from
confusing parts to orderly wholes. Signs and images are
fragments
of experience
that
reflect
our perception
of material objects. Material
objects, in turn, become instruments of action. Signs, things, and
actions are organized in complex environments by a unifying idea
or thought. But there is no reason to believe that parts and wholes
must be treated in ascending rather than descending order. Parts
and whole are of many types and may be defined in many ways. 8
Depending on how a designer
wishes to explore and organize expe-
rience,
the sequence
could just as reasonably
be regarded
as a descent
from chaotic environments to the unity provided by symbols and
images. In fact, signs, things, actions, and thoughts are not only
interconnected, they also interpenetrate and merge in contempo-
rary design thinking with surprising consequences for innovation.
These areas
suggest the lineage of design's past and present, as well
as point to where design is headed in the future.

and social
dimensions of this area
are
illustrated
in
works as diverse as George

It is easy to understand that industrial
designers
are
primarily con-
cerned with material
objects.
But the research
reported
in design
literature shows that industrial
designers
have
found new avenues
of exploration
by thinking
about material
objects
in the context
of
signs,
actions,
and thoughts.
For example,
some have considered
material
objects
communicative,
yielding
reflections on the
seman-
tic and rhetorical
aspects
of products.
Others have
placed
material
objects
in the context of experience
and
action,
asking
new ques-
tions about how products function
in situations of use and how
they may
contribute
to or inhibit the
flow of activities.
(Of course,
this is a significant shift from questions
about the internal
func-
tioning
of products and
how the
visual form of a
product
expresses
such
functioning.)
Finally,
others are
exploring
material
objects
as
part
of larger
systems, cycles,
and
environments,
opening
up
a
wide
range
of new questions and
practical concerns or reenergizing
old
debates. Issues
include conservation
and
recycling,
alternative
tech-
nologies, elaborate
simulation
environments,
"smart"
products,
virtual
reality,
artificial
life, and the
ethical,
political,
and
legal dimen-
sions of design.
Comparable
movements
are evident
in each
of the design pro-
fessions: their
primary
concern
begins
in one area, but innovation
comes
when the
initial selection is repositioned
at another
point
in
the framework,
raising
new questions and ideas.
Examples
of this
repositioning
abound. For example,
architecture has
traditionally
been
concerned with buildings
as large
systems
or environments.
For
nearly
twenty
years,
however,
a
group
of architects
have aggres-
sively sought to reposition architecture
in the context of signs,
symbols, and visual communication,
yielding the postmodern
experiment
and trends such as deconstructionist
architecture.
Oxymorons
such
as
"deconstructionist
architecture" are
often the
result of attempts
at innovative
repositioning.
They
indicate
a desire
to break old categories,
as
in the now familiar
and
accepted "con-
structivist art"
and "action
painting."
The
test,
of course,
is whether
experiments
in innovation
yield
productive
results, judged
by indi-
viduals and
by society
as a whole.'9
Some
experiments have
fallen
like
dead leaves at the
first
frost, swept
away
to merciful oblivion.
At present,
the results of deconstructionist
architecture
are mixed,
but the
experiment
will continue until
individuals or groups repo-
sition the problems of architecture and shift general attention
20
toward new questions.
A strikingly different
repositioning is now beginning
in the pro-
fession of graphic
design
and visual
communication. In the late
nineteenth
and
early
twentieth
centuries, graphic
design
was ori-
ented
toward
personal
expression
through image
making.
It
was
an
extension
of the expressiveness
of the fine arts,
pressed
into com-
mercial or scientific
service. This was
modified
under the influence
of "communication
theory"
and semiotics when the role of the
graphic
designer
was shifted
toward that of an
interpreter
of mes-
19) Such
judgments are the
measure
of objec-
tivity in
contemporary
design thinking.
Without
objectivity to ground
the possi-
bilities discoveredin
design,
design thinking
becomes
design sophistry.
20) Architect Richard
Rogers
seeks to repo-
sition the problems of architecture
in a
new perception of multiple
overlapping
systems, rejecting
the notion of a sys-
tem as "linear, static, hierarchical and
mechanical order." According to
Rogers: "Today we know that design
based on linear reasoning must be
superseded by an open-ended archi-
tecture of overlapping systems. This
'systems' approach
allows us to appre-
ciate the world as an indivisible whole;
we are, in architecture, as in other fields,
approaching a holistic ecological view
of the globe and the way we live on it."
Architecture: A Modern View (New
York:
Thames
and
Hudson Inc., 1991),
58. Rogers's notion of "indeterminate
form" derives
not from the ideas of lit-
erary deconstruction but from his
innovative view of multiple systems.

of postmodern architecture from the
perspective of multiple systems, see

A Modern View, 26.

sages. For example, the graphic designer introduced emotional col-
orings of corporate or public "messages" or, in technical terms,
the graphic designer "coded" the corporate message. As a result,
the products of graphic design were viewed as "things" or "enti-
ties" (material texts) to be "decoded" by spectators. Recently,
however, a new approach in graphic design thinking has begun to
question the essentially linguistic or grammatical approach of com-
munications theory and semiotics by regarding visual
communication as persuasive argumentation. As this work unfolds,
it will likely seek to reposition graphic design within the dynam-
ic flow of experience and communication, emphasizing rhetorical
relationships among graphic designers, audiences, and the content
of communication. In this situation, designers would no longer be
viewed as individuals who decorate messages, but as communica-
tors who seek to discover convincing arguments by means of a
new synthesis of images and words. In turn, this will shift atten-
tion toward audiences
as active
participants
in reaching
conclusions
rather than passive recipients of preformed messages.
What works for movements within a design profession also
works for individual designers and their clients in addressing spe-
cific problems. Managers of a large retail chain were puzzled that
customers had difficulty navigating through their stores to find
merchandise. Traditional
graphic design yielded larger signs but no
apparent improvement in navigation-the larger
the sign, the more
likely people were to ignore it. Finally,
a design consultant
suggested
that the problem should be studied from the perspective of the
flow of customer experience. After a period of observing shoppers
walking through stores, the consultant concluded that people often
navigate among different sections of a store by looking for the
most familiar and representative examples of a particular type of
product. This led to a change in display strategy, placing those
products that people are most likely to identify in prominent posi-
tions. Although this is a minor example, it does illustrate a double
repositioning of the design problem: first, from signs to action,
with an insight that people look for familiar
products to guide their
movements; second, from action to signs,
a redesign
of display strat-
egy to employ products themselves as signs or clues to the
organization of a store.
There are so many examples of conceptual repositioning in
design that it is surprising
no one has recognized the systematic pat-
tern of invention that lies behind design thinking in the twentieth
century. The pattern is found not in a set of categories
but in a rich,
diverse, and changing set of placements, such as those identified
by signs, things, actions, and thoughts.
Understanding the difference between a category and a place-
ment is essential if design thinking is to be regarded as more than
a series of creative accidents. Categories have fixed meanings that
are
accepted
within the framework of a theory or a philosophy, and
21) Although
stil a common and
usefuil
way
of studying
visual communication,
this
approach
has lost some of its initial force
in actual design practice
because
it has
moved into personal
idiosyncracy
and a
search
for novelty,
which often distracts
one from the central
tasks of effective
communication. This is evident, for
example, among
those graphic
designers
who have made pedestrian readings
of
deconstructionist literary theory the
rationale
for their
work. Visual experi-
mentation
is
an
important part
of graphic
design thinking, but experimentation
must
finally
be judged
by relevance and
effectiveness
of communication.

discussion of the limits
of semiotics and
design, see Seppo Vakeva, "What Do
We Need Semiotics For?," Semantic
Visions in Design, ed. Susann Vihma

of Industrial Arts

22) Swiss
graphic
designer
Ruedi
Ruegg
has
recently spoken of the need for more
fantasy
and freedom in graphic
design
thinking. Based on his approach, one
might argue that efforts to introduce
deconstructionist literary theory into
graphic
design
have often led to a loss of
freedom and imagination in effective
communication,
contrary
to the claims
of its proponents.

serve as the basis for analyzing
what already
exists. Placements
have boundaries to shape
and constrain
meaning,
but are
not rigid-
ly fixed and determinate. The boundary
of a placement gives a
context
or orientation
to thinking,
but the application
to a specif-
ic situation
can generate
a new perception
of that situation
and,
hence,
a new possibility
to be tested.
Therefore, placements
are
sources
of new ideas and
possibilities
when
applied
to problems
in
concrete circumstances
As an ordered
or systematic approach to the invention of possi-
bilities, the doctrine of placements provides a useful means of
understanding
what many designers
describe as the intuitive or
serendipitous
quality
of their work.
Individual
designers
often
pos-
sess a
personal
set
of placements, developed and
tested
by experience.
The
inventiveness of the designer
lies
in a natural
or cultivated and
artful ability
to return to those
placements
and
apply
them
to a
new
situation,
discovering aspects
of the situation
that affect the final
design. What
is regarded
as
the designer's style,
then,
is sometimes
more
than
just
a
personal
preference
for certain
types
of visual
forms,
materials,
or techniques;
it is a characteristic
way of seeing possibil-
ities
through
conceptual placements. However,
when a designer's
conceptual placements
become
categories
of thinking,
the result can
be mannered imitations of an earlier
invention that are no longer
relevant to the
discovery
of specific possibilities
in a new situation.
Ideas are then
forced
onto a situation rather than discovered
in the
particularities
and novel
possibilities
of that situation..2
For the practicing designer, placements are
primary
and
cate-
gories
are
secondary.
The reverse holds true for design history,
theory,
and
criticism, except
at those moments when a new direc-
tion for inquiry
is opened.
At such times,
a repositioning
of the
problems of design,
such as a change
in the subject matter to be
addressed,
the methods to be employed,
or the principles
to be
explored,
occurs
by means of placements.
Then, history, theory,
or criticism
are "redesigned"
for the individual
investigator and
sometimes
for
groups
of investigators.
As the
discipline
of design
studies adds a reflective and
philosophic
dimension to design his-
tory, theory, and criticism, positive consequences
are
possible.
Historians,
for example, may
reconsider the placement
of design
history
as it has
been
practiced throughout
most of the twentieth
century and work to discover other innovative possibilities.
Discontent
with the results
of current
design
history suggests that
new repositionings
are
called for if the
discipline
is to retain vital-
27
ity and relevance
to contemporary problems.
The doctrine of placements
will require
further
development
if
it is to be recognized
as a tool in design
studies and
design
think-
ing, but it can also be a surprisingly precise
way of addressing
conceptual space
and the
non-dimensional
images
from which
con-
28
crete
possibilities
emerge
for testing
in objective
circumstances.
The natural and spontaneous
use of placements
by designers
is
23) The concept of placements
will remain
difficult to grasp as long as individuals
are
trained
to believe that the only path
of reasoning
begins with categories
and
proceeds
in deductive chains
of propo-
sitions. Designers are concerned with
invention as
well as judgment,
and
their
reasoning is practical because it takes
place in situations where the results are
influenced
by diverse opinions.
24) Some placements have
become so com-
mon in twentieth-century design that
they hardly attract attention.
Nonetheless, such placements are
clas-
sic features
of design thinking, and in
the hands of a skilled designer retain
their inventive
potential. Designer Jay
Doblin sometimes
employed a cascade
of placements
stemming from the basic
placement
"intrinsic/extrinsic."
Doblin's
placements serve as a heuristic device
to reveal the factors
in design thinking
and
product
development.
Other
place-
ments are described by Doblin in
"Innovation, A Cook Book Approach,"
n.d.
(Typewritten.) With different
intent,
Ezio Manzini recently argued
that the
designer
needs two mental instruments
with opposite qualities to examine a
design situation: a microscope and a
macroscope.
The mental
microscope
is
for examining
"how
things work, down
to the smallest
details," particularly
in
regard
to advances
in materials
science.
A further
series of placements
fill out
the microscope to give it efficacy. See
Ezio Manzini, The Materials of
Invention: Materials and Design
(Cambridge:
M.I.T. Press, 1989),
58.
25) The ease with which placements are
converted into categories
should make
any designer or design educator cau-
tious in how they share the conceptual
tools of their work. The placements
that might
shape
an innovative
approach
for the founder of a school of design
thinking often become categories of
truth
in the hands
of disciples
or descen-
dants.
26) Thomas Kuhn was interested in the
repositionings
that
mark revolutions
in
scientific
theory. His study of this phe-
nomenon, perhaps contrary to his
initial
expectations, has helped to alter
the neo-positivist interpretation
of the
history of science. But Kuhn's
Design Issues: Vol. VIII, Number 2 Spring 1992 13
already evident; an explicit understanding of the doctrine
of place-
ments will make it an important element of design as a liberal art.
All men and women require a liberal art of design to live well
in the complexity of the framework based in signs, things,
actions,
and thoughts. On one hand, such an art will enable individuals
to
participate more directly
in this framework and contribute
to its
development. On the other, professional designers could be
regard-
ed as masters
in its
exploration. The ability of designers to discover
new
relationships among signs, things, actions, and thoughts
is one
indication that design is not merely a technical specialization
but
a new liberal art.
The Wicked
Problems Theory of Design
Recent conferences on design are evidence of a coherent,
if not
always systematic, effort
to reach a clearer understanding
of design
as an
integrative discipline. However,
the
participants,
who increas-
ingly come from diverse professions and academic disciplines,
are
not drawn together because they share a common definition
of
design;
a common
methodology,
a common
philosophy,
or even
a
common set of objects to which everyone agrees
that the term
"design"
should
be applied. They
are drawn
together
because
they
share a mutual interest
in a common theme: the conception
and
planning of the artificial.
Different definitions
of design
and differ-
ent specifications
of the methodology
of design
are
variations of
this broad
theme,
each a concrete
exploration
of what is possible
in
the
development
of its
meanings
and
implications.
Communication
is possible
at
such
meetings
because
the
results
of research and
dis-
cussion, despite wide differences
in intellectual and practical
perspectives,
are
always
connected
by this theme
and,
therefore,
supplemental.
This is only possible,
of course,
if individuals
have
the wit to discover what is useful
in each other's
work and can cast
the material
in terms of their
own vision
of design
thinking.
Members of the scientific
community, however,
must be puz-
zled by the
types
of problems
addressed
by professional
designers
and by the patterns
of reasoning they employ. While scientists
share
in the new liberal art of design thinking, they are also mas-
ters of specialized subject
matters
and their related
methods,
as
found
in physics, chemistry, biology, mathematics,
the social
sci-
ences,
or one of the many
subfields into
which
these sciences
have
been divided. This creates one of the central
problems
of com-
munication between
scientists and
designers,
because
the
problems
addressed
by designers
seldom fall
solely
within
the boundaries
of
any one of these
subject
matters.
The
problem
of communication between
scientists
and
design-
ers was evident
in a special
conference
on design
theory held in
New York in 1974.30
This conference was interesting
for several
reasons,
the most significant directly
related
to the content of the
meeting
itself. Reviewed
in one of the initial
papers,"
the "wicked
"paradigm
shifts" were
never devel-
oped to their fullest intellectual
roots
in rhetorical
and dialectical
invention,
which are
based on the theory
of top-
ics. Chaim
Perelman has
developed an
important
contemporary
approach to
what is called here the doctrine of
placements.
See Chaim Perelman
and
L. Olbrechts-Tyteca, The New
Rhetoric:
A Treatise on Argumentation
(Notre Dame: University
of Notre
Dame
Press, 1969).
See also, Stephen E.
Toulmin, The Uses of Argument
(Cambridge:
Cambridge
University
Press,
1958)
for a modern
discovery
of
dialectical topics. Although
remote
from the immediate interests
of
design-
ers,
these
works are cited because
they
deal with
practical
reasoning
and have
important
bearing
on
aspects
of design
theory,
including
the
logic
of decision
making discussed in Simon's The
Sciences of the Artificial.
27)
In
order to solve such
problems,
more
attention should
be given
to the
vari-
ous conceptions
of design held by
designers
in the
past.
This
would
repo-
sition design history from material
objects
or "things"
to thought
and
action.
In other
words,
what
design-
ers
say
and
do, the
history
of their art
as
philosophy
and
practice.
For
a dis-
cussion
of the
subject
matter
of design
history,

Margolin's

coming

Matter and
Methods,"

The
phrase
"non-dimensional
images"
refers to all
images
created
in
the mind
as
part
of design thinking
and,
in
par-
ticular,
to the
various schematizations
of conceptual placements
(e.g.
hierar-
chical,
horizontal,
or in matrix and
table
form)
that
may
aid
invention.
29)
This list could
also
include
the human-
istic
disciplines
and
the fine
arts,
because
there
is as
much
difficulty
in commu-
nicating between some traditional
humanists
and
designers
as between
designers
and
scientists.
This
is evident
in
the
persistent
view that
design
is sim-
ply a decorative
art, adapting
the
principles
of the fine
arts
to utilitarian
ends,
held
by many
humanists.

approach to design proved
to be one of the
central
themes
to which the
participants
often
returned
when
seeking
a connection
between their
remarkably
diverse
and
seemingly
incommensurate
applications
of design. Also significant
was
the
difficulty
that most
of the participants
had
in understanding
each other.
Although
an
observation
of an outsider on the
dynamics
of the meeting,
it is an
excellent
example
of a "wicked
problem"
of design
thinking.
The
wicked
problems
approach
was formulated
by Horst Rittel
in the 1960s,
when design
methodology
was a subject of intense
interest.33
A mathematician, designer,
and former teacher at the
Hochschule
fur Gestaltung (HfG) Ulm, Rittel
sought
an alterna-
tive to the linear,
step-by-step
model of the design
process being
explored by many designers
and
design
theorists.34
Although
there
are
many
variations of the linear
model,
its
proponents
hold
that the
design process
is divided into two distinct
phases: problem
defini-
tion and
problem
solution. Problem
definition
is an
analytic sequence
in which
the
designer determines
all of the
elements of the
problem
and
specifies
all of the requirements
that a successful
design
solu-
tion must have.
Problem solution is a synthetic sequence
in which
the various
requirements
are combined and balanced
against
each
other,
yielding
a final
plan
to be carried
into production.
In the abstract,
such a model
may appear
attractive because
it
suggests
a methodological
precision
that
is,
in its
key
features,
inde-
pendent
from the perspective
of the individual
designer.
In fact,
many
scientists and business
professionals,
as well as some
design-
ers,
continue
to find
the
idea of a linear model
attractive, believing
that it represents
the
only hope
for a "logical"
understanding
of the
design process.
However,
some critics were
quick
to point
out two
obvious points of weakness:
one, the actual
sequence
of design
thinking
and decision
making
is not a
simple
linear
process;
and
two,
the problems addressed
by designers
do not, in actual practice,
yield to any linear
analysis and
synthesis yet proposed.
Rittel argued
that most
of the problems
addressed
by designers
36
are wicked
problems. As described
in the first
published
report of
Rittel's
idea,
wicked
problems
are
a "class of social
system
problems
which are
ill-formulated, where the
information is confusing, where
there are
many
clients and
decision makers with
conflicting values,
and
where the ramifications
in the whole system
are
thoroughly
confusing."37
This is an amusing
description
of what confronts
designers
in every new situation.
But most important,
it points
toward a fundamental
issue
that
lies behind
practice:
the relation-
ship between
determinacy and
indeterminacy
in design thinking.
The
linear model
of design
thinking
is based on determinate
prob-
lems which
have definite
conditions. The
designer's
task is to identify
those conditions
precisely
and then calculate
a solution. In con-
trast, the wicked-problems
approach
suggests that there is a
fundamental
indeterminacy
in all
but the most trivial
design prob-
32) Graph theory, developed by the math-
ematician
Frank
Harary,
also served to
connect the work of researchers in
many
areas. It was reported by the
orga-
nizers that Harary, who attended this
conference and delivered the paper
"Graphs as Designs," suggested that
the basic structure of design theory
could be found in his work on structural
models. Whether or not Harary
made
such a suggestion,
it is possible to see in
graph theory, and, notably, the theory
of directed graphs, a mathematical
expression of the doctrine of place-
ments. Comparison may establish a
surprising
connection between the arts
of words and the mathematical
arts of
things,
with further
significance
for the
view of design as a new liberal art.
"Schemata" are the connecting link,
for
placements
may be schematized as fig-
ures
of thought, and schemata
are
forms
of graphs, directed or otherwise. For
more on graph theory see F. Harary,
R. Norman, and D. Cartwright,
Structural
Models: An Introduction to
the Theory of Directed Graphs (New
York: Wiley, 1965).
33) A series of conferences on Design
Methods held in the United Kingdom
in 1962, 1965, and 1967, led to the for-
mation of the Design Research
Society
in 1967,
that
today continues to publish
the journal Design Studies. Parallel
interest in the United States
led to the
establishment
of the Design Methods
Group in 1966, which published the
DMG Newsletter (1966-71), renamed
the DMG-DRS Journal: Design
Research and Methods, and then
renamed
in 1976 and published to the
present as Design Methods and
Theories. For one attempt to describe
and integrate
a set of methods used in
design thinking, see J. Christopher
Jones, Design Methods: Seeds of
Human Futures
(1970; rpt New York:
John Wiley & Sons, 1981). Many
of the
methodsJones presents
are conscious-
ly transposed from other disciplines.
However, they all can be interpreted
as techniques for repositioning design
problems, using placements
to discov-
er new possibilities.
34) Rittel,
who died in 1990, completed his
career
by teaching
at the University of
California at Berkeley and the
University of Stuttgart.

graphical

lems-problems where,
as Rittel suggests, the "wickedness"
has
already been
taken
out to yield
determinate or analytic
problems.
To understand
what this
means, it is important
to recognize
that
indeterminacy
is quite
different from
undetermined.
Indeterminacy
implies
that
there
are
no definitive
conditions
or limits to design
problems.
This is evident, for example,
in the ten properties
of
wicked
problems
that
Rittel
initially
identified
in 1972.3
(1) Wicked
problems
have no definitive
formulation,
but
every
formulation of a
wickedproblem
corresponds
to the formulation of a solution.
(2) Wicked
problems
have
no stopping
rules.
(3) Solutions to wicked
problems
cannot
be
true
or
false,
only good or bad.
(4)
In
solving
wicked
problems
there is no exhaustive list
of admissible
operations.
(5)
For
every
wicked
problem there is always more than
one
possible
explanation, with
explanations
depending
on the Weltanschauung
of the designer.39
(6) Every wicked
problem
is a symptom of another,
"higher
level,"
problem."
(7) No formulation and
solution of a wicked
problem
has a definitive
test.
(8)
Solving
a
wicked
problem is a "one shot"
operation,
with no room for trial and error. 1
(9) Every
wicked
problem
is unique.
(10) The wicked
problem solver has no right to be
wrong-they are
fully responsible
for their
actions.
This is a remarkable
list,
and
it is tempting
to go no further
than
elaborate the meaning
of each
property,
providing
concrete
exam-
ples
drawn
from
every
area of design
thinking.
But
to do so would
leave a
fundamental
question
unanswered.
Why
are design
problems
indeterminate
and, therefore, wicked? Neither Rittel nor any of
those
studying wicked
problems
has
attempted
to answer this
ques-
tion,
so
the
wicked-problems
approach
has
remained
only
a
description
of the
social
reality
of designing
rather
than the
beginnings
of a well-
grounded
theory of design.
However,
the answer to the question
lies in something
rarely
considered: the
peculiar
nature
of the
subject
matter
of design.
Design
problems
are
"indeterminate" and
"wicked"
because
design
has no
special
subject
matter
of its
own
apart
from
what
a
designer
conceives
it to be. The
subject
matter of design
is
potentially universal
in
scope,
because
design
thinking
may
be
applied
to any
area of human
expe-
rience. But
in the
process of application,
the
designer
must
discover
or invent
a
particular
subject
out of the
problems
and issues of spe-
cific circumstances. This sharply contrasts with the disciplines
of
science,
which are
concerned
with understanding
the principles,
laws,
rules,
or
structures that
are
necessarily
embodied
in
existing
sub-
ject matters. Such subject matters are undetermined or
35) Bazjanac presents an interesting com-
parison of linear models and the wicked
problems approach.
36) The phrase wicked problems was bor-
rowed from philosopher Karl Popper.
However, Rittel developed the idea in
a different direction. Rittel is another
example
of someone initially influenced
by neo-positivist
ideas
who, when con-
fronted with the actual processes of
practical reasoning in concrete circum-
stances, sought to develop a new
approach
related to rhetoric.
37) The first published report of Rittel's
concept of wicked problems was pre-
sented by C. West Churchman,
"Wicked Problems," Management
Science, (December 1967), vol. 4, no.
14, B-141-42. His editorial is particu-
larly interesting
for its discussion
of the
moral problems
of design and planning
that can occur when individuals mis-
takenly
believe that
they
have
effectively
taken the "wickedness"
out of design
problems.

more properties
to his
initial list.
39) Weltanschauung
identifies the intellec-
tual perspective of the designer as an
integral part of the design process.
40) This property suggests the systems
aspect of Rittel's approach.
41) Rittel's example is drawn from archi-
tecture,
where it is not feasible to rebuild
a flawed building. Perhaps
the general
property should be described as
.entrapment"
in a line of design think-
ing. Designers
as well as their
clients or
managers
are often "entrapped"
dur-
ing the development phase of a new
product and are unable, for good or
bad
reasons,
to terminate a weak
design.
For a brief illustration of entrapment
in the product development process of
a small midwestern company, see

Buchanan,

Managing the Entrapment Trap,"

under-determined, requiring further investigation to make them
more fully determinate.
But they are not radically
indeterminate
in
42
a way directly comparable
to that of design.
Designers conceive their subject matter
in two ways on two lev-
els: general and particular.
On a general level, a designer forms an
idea or a working hypothesis about the nature of products or the
nature of the humanmade
in the world. This is the designer's view
of what is meant, for example, by the "artificial" in relation to the
"natural."
In this sense,
the designer
holds a broad view of the nature
of design and the proper scope of its application. Indeed, most
designers, to the degree that they have reflected on their discipline,
will gladly, if not insistently, explain on a general level what the
subject matter of design is. When developed and well presented,
these explanations
are
philosophies or proto-philosophies of design
that exist within a plurality of alternative views. 3 They provide an
essential framework for each
designer
to understand and explore
the
materials, methods, and principles of design thinking. But such
philosophies do not and cannot constitute sciences of design in the
sense of any natural, social, or humanistic science. The reason for
this is simple: design is fundamentally concerned with the particu-
lar, and there is no science of the particular.
In actual practice, the designer
begins with what should be called
a quasi-subject matter, tenuously existing within the problems and
issues of specific circumstances. Out of the specific possibilities of
a concrete situation, the designer must conceive a design that will
lead to this or that particular product. A quasi-subject matter is
not an undetermined subject waiting to be made determinate. It is
an indeterminate subject waiting to be made specific and concrete.
For example,
a client's brief does not present
a definition of the sub-
ject matter of a particular design application. It presents a problem
and a set of issues to be considered in resolving that problem. In
situations where a brief specifies in great detail the particular fea-
tures of the product to be planned, it often does so because an
owner, corporate executive, or manager
has attempted to perform
the critical task of transforming problems and issues into a work-
ing hypothesis about the particular
features of the product to be
designed.
In effect,
someone has attempted
to take the "wickedness"
out. Even in this situation, however, the conception of particular
features remains only a possibility that may be subject to change
through discussion and argument.
This is where placements take on special significance as tools of
design thinking. They allow the designer to position and reposi-
tion the problems and issues at hand. Placements are the tools by
which a designer intuitively or deliberately shapes a design situa-
tion, identifying the views of all participants, the issues which
concern
them, and
the invention
that
will serve as a working hypoth-
esis for exploration and development. In this sense, the placements
selected by a designer are the same as what determinate subject
42) There is one case
in which even the
sub-
ject matters of the sciences are
indeterminate. The
working hypothe-
ses of scientists invariably
reflect
distinctive philosophic
perspectives
on
and interpretations of
what constitutes
nature and natural processes.
This
is a
factor
in
accounting
for
the
surprising
pluralism of philosophies
among prac-
ticing scientists and suggests
that even
science is shaped by an
application
of
design thinking,
developed along
the
lines of Dewey's notion
of "intention-
al operations." Even from this
perspective, however,
scientists
are con-
cerned with understanding
the universal
properties of
what
is,
while designers
are
concerned
with
conceiving
and
plan-
ning
a
particular
that does not yet exist.
Indeterminacy
for
the
scientist
is
on
the
level of second-intention,
while the sub-
ject matter remains, at the level of
first-intention, determinate
in the man-
ner described. For the designer,
indeterminacy belongs
to both first-
and second-intention.
43) For
a brief
discussion
of different
con-
ceptions of subject
matter on this level
held by three contemporary
designers,
Ezio Manzini, Gaetano
Pesce, and
Emilio Ambaz,
see Richard
Buchanan,
"Metaphors,
Narratives,
and Fables
in
New Design
Thinking," Design
Issues
VII-1 (Fall, 1990): 78-84. Without
understanding
a
designer's
view of sub-
ject
matter
on
the
general
level,
there is
little
intelligibility
in
the shifts that occur
when a designer moves,
for example,
from
designing
domestic products to
graphic design
or architecture. Such
shifts
are
usually
described
in terms
of
the designer's "personality"
or "cir-
cumstances,"
rather than the continued
development
of a
coherent
intellectual
perspective
on the artificial.
44)
Failure
to include
professional
design-
ers as
early
as
possible
in the
product
development process is one of the
sources of entrapment
in corporate
culture. Professional
designers
should
be
recognized
for their
ability
to con-
ceive
products
as well as
plan
them.
Design Issues: Vol. VIII, Number 2 Spring 1992 17
matters
are for the scientist.
They are
the quasi-subject
matter of
design thinking, from which the designer fashions a working
hypothesis
suited to special
circumstances.
This helps to explain how design functions
as
an integrative
dis-
cipline. By using placements
to discover or invent a working
hypothesis,
the designer establishes
a principle
of relevance
for
knowledge
from the arts and sciences,
determining
how such
knowl-
edge
may be useful
to design
thinking
in a particular
circumstance
without
immediately
reducing
design to one or another
of these
dis-
ciplines. In effect, the working hypothesis that will lead to a
particular
product
is the principle
of relevance,
guiding the
efforts
of designers to gather
all available knowledge
bearing on how a
product
is finally
planned.
But
does the designer's
working hypothesis
or principle
of rele-
vance suggest
that
the product
itself is a determinate
subject
matter?
The answer involves
a critical
but often
blurred distinction
between
design
thinking
and the activity
of production
or making.
Once a
product
is conceived,
planned,
and produced,
it may indeed
become
an object
for study by any of the arts
and sciences-history, eco-
nomics,
psychology,
sociology,
or anthropology.
It may even
become
an object for study by a new humanistic science
of production
that
we could
call the "science of the artificial,"
directed
toward
under-
standing
the nature, form,
and uses of humanmade
products
in all
of their
generic
kinds.45
But in all such studies, the activities
of design
thinking
are
easily forgotten
or are reduced to the kind of product
that
is
finally produced.
The
problem
for
designers
is to conceive and
plan
what does not
yet exist,
and this occurs
in
the context
of the inde-
terminacy
of wicked
problems,
before
the
final
result
is known.
This
is the creative or inventive
activity
that Herbert Simon
has
in mind when
he speaks
of design
as a science
of the artificial.
What
he means is "devising
artifacts
to attain
goals"
or, more
broadly,
"doctrine
about
the design
process."46
In this sense,
Simon's
sci-
ence of the artificial is perhaps
closer to what Dewey means
by
technology as a systematic
discipline
of experimental
thinking.
However, Simon has little to say about the difference between
designing
a
product
and
making
it.
Consequently,
the "search"
pro-
cedures
and
decision-making protocols
that he
proposes
for
design
are
largely analytic,
shaped
by his philosophic
view of the deter-
minacies that
follow
from the natural
laws that surround
artifacts.
For
all of the
insight
Simon
has
in distinguishing
the artificial
as
a domain
of humanmade
products
different
from
objects
created
by
natural
processes,
he does not capture
the radical
sense
in which
designers
explore
the essence
of what the artificial
may
be
in human
48
experience.
This is
a synthetic
activity
related to indeterminacy,
not
an activity
of making
what is undetermined
in natural
laws more
determinate
in artifacts.
In short,
Simon
appears
to have conflated
two sciences of the artificial:
an inventive
science
of design
think-
ing which has no subject matter aside from what the designer
45)
The
earliest example
of this science
is
Aristotle's
Poetics. Although
this
work
is
directed
toward
the
analysis
of liter-
ary productions and tragedy in
particular,
Aristotle
frequently
discusses
useful
objects
in terms
of the princi-
ples
of poetic
analysis.
"Poetics,"
from
the Greek
word for
"making,"
is used
by
Aristotle
to refer to productive
sci-
ence or the science
of the artificial,
which he
distinguishes
both
from
the-
oretic and practical
sciences. Few
investigators
have
recognized
that poet-
ic
analysis
can
be extended
to the
study
of making
"useful" objects.
When
designer
and
architect
Emilio Ambaz
refers
to
the
"poetics
of the
pragmatic,"
he means
not only esthetic
or elegant
features
of everyday
objects,
but also
a method
or
discipline
of analysis
that
may
contribute to design
thinking.
46) Simon,
The
Sciences
of the Artificial,
52-53.
47)
For
Simon,
the
"artificial"
is an
"inter-
face" created within a materialist
reality:
"I
have
shown
that
a
science
of
artificial phenomena is always in
imminent danger
of dissolving
and
vanishing.
The peculiar
properties
of
the artifact lie on the thin interface
between
the
natural
laws within it and
the natural
laws without."
Simon,
The
Sciences
of the Artificial,
57. This is
18
conceives it to be, and a science of existing humanmade products
whose nature Simon happens to believe is a manipulation
of mate-
49
rial and behavioral laws of nature.
Design is a remarkably supple discipline, amenable to radical-
ly different interpretations
in philosophy as well as in practice.
But
the flexibility of design often leads to popular misunderstanding
and clouds efforts to understand its nature. The history of design
is not merely
a history of objects. It is a history of the changing
views
of subject matter held by designers and the concrete objects con-
ceived, planned, and produced as expressions of those views. One
could go further and say that the history of design
history
is a record
of the design historians'
views regarding what they conceive to be
the subject matter of design.
We have been slow to recognize the peculiar indeterminacy of
subject
matter
in design
and its impact
on the nature of design think-
ing. As a consequence, each of the sciences that have come into
contact with design has tended to regard
design as an "applied"
ver-
sion of its own knowledge, methods, and principles. They see in
design an instance of their own subject matter
and treat design as a
practical
demonstration
of the scientific
principles
of that
subject
mat-
ter. Thus, we have the odd, recurring situation in which design is
alternately regarded
as "applied"
natural science, "applied" social
science, or "applied"
fine art. No wonder designers and members
of the scientific community often have difficulty communicating.
Design and Technology
Many problems remain to be explored
in establishing
design
as a lib-
eral
art of technological culture. But as it continues to unfold in the
work of individual
designers
and in reflection
on the nature of their
work,50 design is slowly restoring the richer meaning of the term
"technology" that was all but lost with the rise of the Industrial
Revolution. Most people continue to think of technology in terms
of its
product rather
than its form as a discipline
of systematic
think-
ing. They regard
technology as things and machines,
observing
with
concern that the machines
of our culture often appear
out of human
control,
threatening
to trap
and
enslave rather than liberate. But there
was a time in an earlier period of Western culture
when technology
was a human activity operating
throughout the liberal
arts. Every
liberal
art had its own technologia
or systematic
discipline.
To pos-
sess that
technology or discipline
of thinking
was to possess
the liberal
art,
to be human, and to be free in seeking one's place in the world.
Design also has a technologia, and it is manifested in the plan
for every new product. The plan is an argument, reflecting the
deliberations of designers and their efforts to integrate knowledge
in new ways, suited to specific circumstances and needs. In this
sense, design is emerging as a new discipline of practical reason-
ing and argumentation,
directed
by individual
designers
toward one
or another of its major thematic variations in the twentieth cen-
one expression of the positivist or
empiricist philosophy that guides
Simon's theory of design.
48) For Simon, the equivalent
of a wicked
problem is an "ill-structured prob-
lem." For Simon's views on how
ill-structured problems may be
addressed, see "The Structure of Ill-
Structured Problems," Models of
Discovery (Boston: D. Reidel, 1977),
305-25. This paper
has interesting
con-
nections with the doctrine of
placements because placements may
be used to organize and store memo-
ries, and Simon is particularly
concerned with the role of long-term
memory in solving ill-structured
prob-
lems. But Simon's methods are still
analytic, directed toward the discov-
ery of solutions in some sense already
known rather than the invention of
solutions yet unknown.
49) Although Simon's title, The Sciences
of the Artificial,
is a perfectly
adequate
translation of what we have come to
know in Western culture
as Aristotle's
Poetics, Simon seems unaware of the
humanistic tradition of poetic and
rhetorical
analysis of the artificial that
followed from Aristotle. This is not
an antiquarian
issue, because the study
of literary production-the artificial
formed
in words-prefigures the issues
that surround the study of the artifi-
cial in all other types of useful objects.
Aristotle carefully distinguished the
science of the artificial from the art of
rhetoric.
When Aristotle comes to dis-
cuss the thought that is presented in
an artificial object such as a tragedy,
he pointedly refers the reader to his
treatise on the inventive art of rhetoric
for the fullest elaboration
of the issue.
However, Simon deserves less criti-
cism for overlooking this connection
than humanists
who have been amaz-
ingly neglectful, if not scornful, of the
rise of design and technology in the
twentieth century.
50) One example of such reflection is the
interdisciplinary
conference "Discovering
Design,"
organized
by R. Buchanan
and
V. Margolin
and held at the University
of Illinois at Chicago in 1990. The col-
lected
papers
from this
conference will be
published as Discovering Design:
Explorations
in Design Studies.

tury: design
as communication, construction, strategic planning,
or
systemic integration.52
The
power
of design as deliberation and
argument
lies in overcoming the limitations of mere verbal or
symbolic argument-the separation
of words and things, or the-
ory
and
practice
that remains a
source
of disruption and confusion
in contemporary
culture.
Argument
in design thinking moves
toward the concrete
interplay
and
interconnection of signs, things,
actions, and thoughts. Every designer's sketch, blueprint, flow
chart, graph, three-dimensional model, or other product propos-
al is an
example of such
argumentation.
However, there
is
persistent confusion about the different modes
of
argumentation employed by the various design professions. For
example,
industrial
design, engineering, and marketing each employ
the discipline
of design thinking, yet their
arguments
are often
framed in sharply
different
logical
modalities. Industrial
design
tends to stress what is
possible
in the
conception
and
planning of
products; engineering tends
to stress what is necessary
in consid-
ering materials, mechanisms, structures,
and
systems; while
marketing
tends to stress
what
is contingent
in
the
changing
atti-
tudes and
preferences
of potential
users. Because of these
modal
differences
in approaching design problems,
three
of the most
important professions
of
design thinking
are
often regarded
as bit-
ter
opponents
in
the
design enterprise, irreconcilably
distant
from
each other.54
What
design
as
a liberal art
contributes
to this
situation is
a new
awareness of how
argument
is the central theme that cuts across
the
many
technical
methodologies employed
in each
design pro-
fession.
Differences
of modality may
be complementary ways
of
arguing-reciprocal expressions
of
what conditions
and
shapes
the
"useful"
in
human
experience.
As
a liberal art
of
technological
cul-
ture, design points
toward
a new
attitude about the
appearance
of
products. Appearance
must
carry
a deeper, integrative argument
about the nature of
the
artificial
in
human
experience.
This
argument
is a
synthesis
of three lines
of reasoning:
the ideas
of designers
and
manufacturers
about
their
products;
the internal
operational logic
of
products;
and the desire and
ability
of
human
beings
to use
prod-
ucts
in
everyday
life
in
ways
that reflect
personal
and social values.
Effective
design depends
on the
ability
of designers
to integrate
all
three
lines
of reasoning.
But
not as isolated factors
that
can
be
added
together
in
a simple
mathematical
total,
or as isolated sub-
ject
matters that
can
be studied
separately
and
joined late
in the
product development process.
The new liberal art of design thinking
is
turning
to the
modality
of impossibility.
It
points,
for
example,
toward the
impossibility
of
rigid
boundaries between industrial
design, engineering,
and
mar-
keting.
It
points
toward the
impossibility of relying on any one of
the
sciences
(natural, social,
or
humanistic)
for
adequate
solutions to
what are the
inherently
wicked
problems
of
design thinking. Finally,
52) For Rittel's view of argumentation
in
design, see Rittel and Webber,
Dilemmas, 19. Also discussed in
Bazjanac, "Architectural
Design
Theory:
Models of the Design Process," Basic
Questions of Design Theory. Students
report
that late
in his career Rittel came
to recognize the affinity between his
approach
and rhetoric.
53) The necessary is sometimes referred
to as "capacity"
or "capability"
in engi-
neering. For a useful introduction to
engineering design, see M. J. French,
Invention and Evolution: Design in
Nature and Engineering
(Cambridge:
Cambridge University Press, 1988).
54) Philip Kotler, the internationally rec-
ognized expert on marketing, has
suggested that what many industrial
designers
object to in marketing
should
not be regarded
as marketing itself,
but
as bad marketing. For new develop-
ments in marketing,
see Philip Kotler,
"Humanistic Marketing: Beyond the
Marketing Concept," Philosophical
and Radical Thought in Marketing,

Firat,

P. Bagozzi (Lexington,

it points toward
something
that is often
forgotten,
that what
many
people
call "impossible"
may actually
only be a limitation
of imag-
ination
that can be overcome
by better
design
thinking. This is not
thinking directed
toward a technological
"quick
fix"
in hardware
but toward
new integrations
of signs,
things,
actions, and
environ-
ments that
address the concrete
needs and values of human
beings
in diverse circumstances.
Individuals
trained
in the
traditional arts
and
sciences
may con-
tinue to be puzzled
by the neoteric
art of design."
But the masters
of this new liberal
art are
practical
men
and
women,
and
the dis-
cipline
of thinking
that
they
employ
is gradually
becoming
accessible
to all individuals
in everyday
life.
A common
discipline
of design
thinking-more than
the particular
products created
by that dis-
cipline today-is changing our culture, not only in its external
manifestations but in its internal
character.
55) "Neoteric" is a term often associated
in Western culture with the emergence
of new liberal arts. Neoteric arts are
arts of "new learning." For a discus-
sion of neoteric and paleoteric liberal
arts, see Richard Buchanan, "Design
as a Liberal Art," Papers: The 1990
