21 managers of a company of just over 100 employees manufactured high-tech equipment on the west coast of the United States. Three types of ties were collected:

  • friends: managers' answers to the question "Who is your friend?"

  • advice: managers' answers to the question "To whom do you go to for advice?"

  • reports: "To whom do you report?" based on company reports

The data is anonymised, but four nodal attributes are included:

  • age: the manager's age in years

  • tenure: the manager's length of service

  • level: the manager's level in the corporate hierarchy, where 3 = CEO, 2 = Vice President, and 1 = manager

  • dept: one of four departments, B, C, D, E, with the CEO alone in A
