Abstract : Software metrics (or measurements) which are used to indicate and predict levels of software quality were extended from previous research to include considerations for distributed computing systems. Aspects of the products of software life-cycle activities which could affect the quality levels of software, and metrics to measure them, were identified. Two new quality factors, survivability and expandability, were validated. A Guidebook for Software Quality Measurement was produced to aid in setting quality goals, applying metric measurements, and making quality level assessments. New metrics for interoperability and reusability were also included in the guidebook. The objective of this contract was to conduct exploratory development of techniques to measure system quality with a perspective on both software and hardware from a life cycle viewpoint. The effort was expected to develop and validate metrics for software quality on networked computers and distributed systems; i.e., systems whose functions may be tightly distributed over microprocessors or specialized devices such as data base machines. At the same time, the effects hardware has on software was to be studied, as well as the trade-offs between hardware, firmware, and software. The results of this research are reported in this volume.
