Systems engineering: A problem-solving approach to improving program performance

Evaluation methodologies have generally emphasized the measurement and assessment of program merit, as reflected by the achievement of program objectives. Less attention has been devoted to analyzing and explaining the reasons for deficient performance and, more importantly, what needs to be modified to improve performance. While evaluators do identify performance problems, the identified problems are not always analyzed. Consequently, the information reported to decision makers may be incomplete, inconclusive, and of limited utility in the decision-making process. This article describes an evaluation methodology based on problem solving techniques which can be effective and efficient in defining and analyzing problems which impair program performance. The model can be applied in evaluations where the purpose is to provide decision makers with information and recommendations to improve program performance and provide an alternative to those evaluation models which emphasize the assessment of program merit. The model also provides a potentially unique cost/benefit methodology for estimating the potential worth of improving program performance (i.e., solving the problem).
