model we defined has been examinated by the analysis of a case study in order to
further investigate the ideas suggested by the theory. The research method we used is
the one of the case study as suggested by Yin [19]. This method has been selected as a
consequence of the exploratory purpose of our paper. Our analysis has been
conducted in the Italian office of Martinelli Consultants, one of the leading groups
worldwide in organization and technology consulting.
We used three techniques for data collection, so respecting the principle of
triangulation: participant-observation, qualitative interview and document analysis.
Participant-observation took place for a period of more than six months, during
which one of the authors joined the Italy Knowledge Management team of Martinelli
Consulting. In this period the researcher has been equiparated to the other members of
the team, carrying out the same activities, having the same working instruments than
his colleagues (desk, laptop, corporate e-mail, telephone), sharing the same working
spaces, and participating to all the events of the team life (meetings, work-in-
progress, training courses, presentations and so on). This helped to avoid the
“observer paradox” described by Labov [10], making the behavior of the observed
people not reactive.
A significant part of the data collection has been developed by carrying out
qualitative semi-structured interviews we made to 52 consultants in Martinelli. The
choice of the people and the groups to be interviewed was made following a
systematic approach in order to have a good representation of the entire Martinelli.
With the help of the Head of Knowledge Management Office we selected eight
groups working on the typical Martinelli business, and we intervewed people
covering all the organizational positions and different roles within the workgroups.
The contents of our interviews were related first of all to the composition of the
workgroup, to better interpret the information we obtained. A second section of the
interview protocol referred to the five or six macro tasks that the workgroup carried
out. In the same section was asked to specify the knowledge areas used to execute the
tasks that had been indicated. In the third section of the interview protocol we
investigated the four characteristics of codifiability, epistemic complexity, task
dependence and organizational competitiveness of the knowledge areas indicated by
the respondents, using the following scale: 1-3 (low), 4-6 (intermediate), 7-9 (high).
The scales were taken from Zander and Kogut’s [17] work on practices and their
transfer, and were adapted to the concept of knowledge areas that were critical in this
study. While the “codificability” construct was quite well-defined and applicable to
our context, some adaptations were necessary to measure “complexity.” We
considered “teachability” and “output observability” as part of a more expanded
knowledge complexity construct. Indeed, in this study the ease of defining cause-and-
effect relationships, and the variety of problems and solutions, are also part of the
complexity measure. Questions related to codifiability: Existing work manuals and
operating procedures describe precisely what people working in this knowledge area
actually do; most of the solutions to the problems related to this knowledge area are
described in written manuals; the outputs related to this knowledge area are well
documented. Questions related to epistemic complexity: a competitor can easily learn
how we produce outputs related to this knowledge area by analysing carefully all the
related resources used and produced for these outputs; the quality of the output
depends more on the judgment of the experts than on well defined rules; within the
practice of this knowledge area, a given action has a known outcome; the problems
