This research is concerned with identifying a model of the source selection process as used in Aeronautical Systems Division, Air Force Systems Command (ASD) and evaluating the strengths and weaknesses of the process in relation to stated Department of Defense and Air force objectives. Information was gathered from a review of past source selection cases and a series of interviews with ASD source selection personnel. A computer model was constructed to simulate the effects of the decision forming techniques observed on the possible outcomes of source selections. A resulting descriptive model provides a basis for better understanding of the quality of decision information provided by the process and forms a framework for improving the source selection process.
