This monograph discusses how to bring about changes and reforms in the area of human services. The introduction defines human services and briefly discusses some reform movements and whether or not viable change methods are available. Section I discusses the roles of various change participants including the change agent, lobbyist, ombudsman, coordinator, advocate, and citizen participation. Different change processes are examined in the second section. Included among these are project planning management; coalitions; community organization; community development; program evaluation; negotiating and bargaining; social change and the courts; and militancy and conflict. The third and final section treats the future of American human services in the 1980s under four interacting influences: evolving ideologies and social values, emerging technologies, changing administrative practices, and modified program patterns. An appendix contains case studies documenting actual implementation of reform methods in the human services field. (Author/RM)
