This article proposes aframework for determining strategies in nonprofit social services organizutions. A review of the literature concerning strategy choice models is combined with an analysis of the unique characteristics of nonprofit social services organizations to develop the proposedframework, which improves on existing models by encompassing a wider array of strategicfactors and being applicable to a wide variety ofnonprofit organizations. The author provides examples of the model's applications, discusses the usefulness and limifations of the model, and concludes with suggestionsforfuture research.HE success of a nonprofit social services organization (NPSO) often depends on formulating strategies appropriate for the com-T petitive and environmental realities that the organization faces.These realities are increasingly important given the increased demands for services, accompanied by decreased funding caused by government cutbacks (Nielsen, 1986) and societal changes. Nonprofit organizations are also facing increased environmental turbulence (Perlmutter and Gummer, 1994;McMurtry, Netting, and Kettner, 1990), which often requires organizational adaptations. This article proposes a framework for strategy formulation in NPSOs. The article is organized as follows: The unique characteristics of NPSOs are examined, followed by a survey of the literature on strategy choice models. Models that have been applied to nonprofit organizations are given special consideration, and the need for a better model is examined. The strategic needs and unique characteristics of NPSOs are then considered in developing a strategy choice framework. The article concludes with a demonstration of the use of the model, a discussion of the limitations and usefulness of the framework, and suggestions for future research.
