A distillation of RAND experience and research in the measurement and evaluation of computer system performance into a procedural framework for an improvement effort consisting of seven phases: (1) understanding the system, (2) analyzing operations, (3) formulating performance improvement hypotheses, (4) analyzing probable cost-effectiveness of modifications, (5) testing specific hypotheses, (6) implementing appropriate combinations of modifications, and (7) testing the effectiveness of the implemented modifications. All phases are discussed briefly, but the report concentrates on the critical first three. A preliminary questionnaire is provided that will produce the information necessary for phase 1, and a detailed questionnaire is suggested that will provide the more specific and quantitative information necessary for phase 2. Methods of analysis are indicated for the transition from phase 2 to phase 3, and a number of general hypotheses are presented in the categories of reducing workload, tuning, and upgrading the system. 62 pp. Ref.
