This network represents the friendship ties of 36 employees of a small hi-tech company.

Background:

The case is a small hi-tech computer firm which sells, installs, and maintains computer systems. The network contains the friendship ties among the employees, which were gathered by means of the question: Who do you consider to be a personal friend? Three employees (Fran, Quincy, and York) did not return the questionnaire. Note that most friendship nominations are reciprocated, but not all (112 out of 147). A friendship choice (arc) is only included in the network if both persons involved acknowledge it.
