The paper focuses on catalysts needed for interagency cooperation in multi-service delivery systems for handicapped individuals. The importance of interfacing personal and environmental profiles is emphasized, and an approach matching aspects of the person and the environment is described. A behavioral skill profile of the person would be matched with environmental characteristics (including available living-work options, behaviors required to adapt successfully to the environments, and the personality characteristics of the environment). Two case histories illustrate ways in which a person-environmental profile can be used in skill training, procuring prostheses, and modifying the environment. A second catalyst, systematic transitional planning, is considered in terms of an ITP (Individualized Transition Plan) model which addresses client and systems-level needs. (CL)
