The utilization of the logic model as a system level planning and evaluation device

Many questions exist about how to evaluate the impacts of local human services delivery systems. This paper presents a potential mechanism for such evaluations and describes the experiences of a large, urban United Way. The mechanism focuses olm Tool called the logic model. ii description of the local United Way planning and evaluation process and how this process was enhanced through the utilization of the logic model is provided. The United Way experience suggests that the logic model may, have application to planning domains where the desire is to achieve long term social objectives through the implementation of multiple, shorter term interventions. The logic model provides a mechanism and conceptual basis for identifying and measuring system impacts. (C) 1997 Elsevier Science Ltd.
