Sutton, Robert I.

& Hargadon, Andrew (1996) - "Brainstorming Groups in Context:


Effectiveness in a Product Design Team"

Authors' Key Points:


The conclusion drawn by psychology researchers that brainstorming is an inefficient technique
is based on a single measure of efficiency (idea generation) and is detached of organizational
context (based on experimental research). The authors contest that approach by suggesting
that organizations that use brainstorming routinely will benefit from this technique in a
variety of ways that can be best understood by understanding its organizational context. The
authors also contest the validity of the notion that brainstorming is a widely used technique
and discuss in great detail the problems of defining performance variables.

Theoretical Strain:

Osborn's concept of Brainstorming is the departure point and extensive literature on


experimental psychology is analyzed and contested (see Stroebe and Diehl, 1994, for an
illustrative example of this approach). Literature on organizational effectiveness is referred to
express the need of developing multidimensional constructs for organizational performance
and a specification of Hackman's
(1985,1987) groups performance criteria is suggested. A diverse literature is called
upon to sustain or help explain the findings of the study.

Research Methods Used:

ethnographic study of a product design consulting firm (IDEO). The study took more than 2
years and was intended to discover how IDEO was able to be so innovative. Afterwards the
focus was directed to brainstorming giving the extensive use of this technique at IDEO. The
research methodology involved observing 24 brainstorming sessions, conducting 60 semi-
structured interviews, having hundreds of informal conversations, tracking the development
of several design teams, collecting company and public data and developing a survey. The
approach to theory used in the study is "knowledge growth by extension" (Weick, 1992, 177).

Findings:

Face to face brainstorming sessions at IDEO serve as more than idea generators, having six
other important consequences:
supporting the organizational memory of design solutions (IDEO acts as a broker of
knowledge)
providing skill variety (and motivation for employees)
supporting an attitude of wisdom (knowledge with awareness of doubt and ignorance)
and experimentation
creating a status auction (competition based on technical skill - peer oriented
meritocracy)
impressing clients
providing income (cost of sessions were billed to clients)
Strengths of Paper:

excellent use of a variety of literature to explain and expand the main points. Very strong and
well developed arguments.

Weaknesses of Paper:

The fact that the study is based in only one case study (and assumedly an extreme one in the
use of brainstorming) hinders the generalization of the results (but is excellent to illustrate
the author's points).

Contribution to the Literature:

extraordinary, in the sense that contests an extensive line of experimental psychology


research and argues for a closer proximity of researchers to the organizational context.
