Dear Doug, Dear Sean,

Thank you for starting this interesting discussion. I would like to add to
the list a book about working groups in organizations:

Holly Arow, Joseph E. McGrath & Jennifer L. Berdahl (2000) Small groups as
complex systems. Formation, Coordination Development, and Adaption.
Thousands Oaks, London, New Delhi: Sage Publications (ISBN 0-8039-7230-X)

The book includes a critical review of the field of small group research,
and introduces the coordination network. A coordination network includes the
coordination networks of a working group, i.e., the networks of all ties
between members, tasks, and tools. As I interprete it, this network includes
not only the social (member) network, but also two other one-mode networks
(the tasks network and the tools network), and three two-mode networks
(task-member, task-tools, member-tools). According to Arrow et al. external
and global dynamics necessitate the group to adapt the coordination network.

I used these ideas for formulating a theory on (collective) performance of
activist groups. I tried to predict failure of the group from the structure
of the entire coordination network (which means that even as the social
network seems to be 'ideal', the group might fail because one or more of the
other five networks harbours problems). Because it could be expected from
social movement theory that the performance of activist groups depends
considerably on adaptation to external and global dynamics, I directed my
study to the effects of incomplete adaptation of the coordination networks
on failure. The idea is very simple: external and global dynamics often
brings about units (members, tasks or resources) exiting or popping up,
which imbalances the coordination network, urging groups to adapt. Because
this seems so logical to do, and many scientific fields intersect here, I
now feel as if I have somehow reinvented the wheel. Therefore, I am glad
that you brought up the subject, and I'm eager to read all literature that
comes up.

Onderwerp: Re: business cases for SNA?


You are looking for the grail, and I sure hope you find it. In my searches
and discussions with other SNA advocates it seems apparent there is a dearth
of research into specific antecedents and consequences of SNA metrics with
relation to organisational performance. This is a potential problem for us
as a research many people asked me when I first entered the
SNA domain..."OK, so you found these what".

Indeed I would like to propose that perhaps those who have an interest in
this area from the SOCNET community may wish to send in refs they know of,
and if there are none, then we could exchange suggestions about what SNA
metrics might be related to organisational performance. I would be happy to
do the collating if people want to send any references and suggestions to
me, and I can post out the mass of results.

The biggest problem as I see it is that every organisation varies in what it
is trying to do, and the processes that it develops and evolves. The network
patterns that exist in an organisation are analogous to the forming of
neural connections when an organism learns. From a learning perspective, the
'best' pattern is one which best suits the task...and the variation between
organisations is so huge that generalisation of findings in any one domain
is problematic. However some suggestions follow:

You may wish to contact Jim Coplien at UMIST...he has done some quantitative
work on looking at SNA metrics across a large number of software development
companies and has identified certain heuristics about patterns which he sees
as indicative of good organisational performance. His email is
[log in to unmask] <mailto:[log in to unmask]>   He has a book in progress which
you may be able to get from him.

Also Kathleen Carley [log in to unmask]
<mailto:[log in to unmask]>  at Cargegie Mellon University has done a
lot of work in modelling organisations with respect to structures and
performance. You may find her work of use.

There is some general work in the management sciences are on the
relationships between different organisational structures (i.e. hierarchies,
matrix structures, anarchic structures, etc) and grouping (functional,
geographical etc) and organisational performance in relation to different
environments and industry types. SNA can offer avenues to assess the degree
to which an organisation follows such patterns, and limited inferences could
be made from such data I suppose.

Some specific (at hand) references follow...relevance may vary:

Subject: business cases for SNA?

*****  To join INSNA, visit
<>   *****


I'm looking for references to or anecdotes of business cases for social
network analysis (SNA).  I'm familiar with research literature that
correlates social network properties with a wide variety of performance
characteristics -- everything from family planning uptake to high-tech
patents.  But are there any more direct, documented cases in the area of
organizational performace?  Something where organizational performace was
measured, SNA was applied and indicated changes were made, and then
organizational performance increased?

thanks much,

Doug Bryan
