as the number of people one can reasonably get to know in an
organisation. I found it interesting that Gore Associates settled on the
number 150. A pretty big difference. I wonder if they meant different things?

validation of the power and importance of groups/community. A powerful
confirmation that how well we know each other determines how well knowledge
flows between us.
The scientist who pioneered this work is Daniel Wegner and his original
paper on this is:
Wegner, D. M. (1986). Transactive memory: A contemporary analysis of the
group mind. In B. Mullen & G. R. Goethals (Eds.), Theories of group
behavior (pp. 185-208). New York: Springer-Verlag.
which is not available on the web however an article that discusses his
theory among other models is available:
"What Do We Know About organisational Memories and Can Current Theories
Contribute to the Development of Knowledge Management Systems?" by Frans
Unfortunately the article is more focused on memory storage than process
but it still gives a reasonable overview of Wegner's model.

Tony and Steve,
thanks for the conversation on Glover's book. I have had it mentioned now by three different groups as a 'must' so have to get it tomorrow.
On the size, I remember that Gore was a military man in WW2. He realised the power of the relationships in a unit - I am not sure what is the name of the one which jumps from 150 to 1000+, however it is this boundary where he saw a real difference. Keeping to these numbers has also assured that Gore does not need the overhead of Personnel department - people act as mentors to each other.
Also, in Heidi's Junior school Headmistress prided herself on knowing the names of all kids by the end of first week. They had between 140-160 kids in the school every year.
Observation - we are doing viral marketing on Glover's book here. Will it spread?
- Hi Lilly,
Great comment. I love the Heidi link and the background on Gore.
