This study verifies certain testing policies and procedures for evaluating mixed online/batch workload systems that had intuitively been thought to be worthwhile. The evaluation was conducted to determine the feasibility of removing an online system and one megabyte of core from RAND's IBM 360/65. The following policies were verified: (1) Complete test planning and pilot testing are extremely valuable; (2) metrics should be chosen prior to test design; (3) decision criteria should be chosen prior to data collection; (4) useful measurement of online systems is possible without expensive equipment. Testing procedures measured areas reflecting the level of service provided to users. 32 pp. Ref.
