A basic tenet of this article is that the nature of an organization’s or group’s boundaries influences the ability of its members to exert influence on other organizations and groups. The organizations in the study are of different size and form, including an informal group, institutional sub-units, educational institutions and a virtual organization. A framework of interpretation is developed to assist in the distinction between organizations on the basis of their boundary properties. The framework is applied to the setting up and development of a virtual organization. It is used to interpret how three key developments between the organizations were possible due to differences in their respective boundary characteristics. The findings are critiqued and implications are suggested.
