David Krackhardt collected cognitive social
structure data from 21 management personnel
in a high-tech, machine manufacturing firm
to assess the effects of a recent management
intervention program. The relation queried
was "Who does X go to for advice and help
with work?" (KRACKAD) and "Who is a friend
of X?" (KRACKFR). Each person indicated not
only his or her own advice and friendship
relationships, but also the relations he or she
perceived among all other managers, generating
a full 21 x 21 matrix of adjacency ratings from
each person in the group.
