The organizational dimension of participation is relevant to planning organizations as well as to service organizations. In this case the organizational output is not direct services but the production of specific plans and proposals. The objective of group participation is to establish plans which call for maximum benefits for a particular population or for the population of a particular district or neighborhood. In either a service organization or a planning organization group participation along the organizational dimension involves persons with a common and primary interest in a particular service or planning organization.
