The report describes the Shared Process Evaluation System (SHAPES), a process analysis system designed to facilitate documenting, rationalizing, and evaluating community development projects. The evaluation process requires five steps. First, the project is described with respect to statements about the original problem situation and demographic conditions of the community prior to the project. Second, the Fields (the project actors) are identified and described. Third, Critical Incidents (events judged as essential to the continuation of the project) are identified and described. Fourth, the Fields are asked to identify and describe Critical Incidents according to a six-category Phase designation (pre-identification of needs, need identification, objective setting, planning, action, and assessment and monitoring of effects). Fifth, the data collected are plotted on descriptive matrices in which the three variables (Fields, Critical Incidents, and Phases) illustrate patterns of Field participation, patterns of shared change, and patterns of individual Field change; data may also be arranged in a time-line display of Critical Incidents. An appended case study describes a field test of SHAPES in a community development program in Williams, Arizona, and provides visual demonstrations of the matrices and time-line display of step five.
