From page 175...
... The previous studies covered the application of statistical, system engineering, and software engineering techniques to improve the development of defense systems. Many of the conclusions and recommendations of these studies are relevant to the development of reliable defense systems, the topic of this study.

... The objectivity of the scoring procedures that were actually imple mented should be assessed and included in the reporting of results. The sensitivity of final reliability, availability, and maintainability estimates to plausible alternative interpretations of test data, as well as subse quent assumptions concerning operating tempo and logistics support, should be discussed in the reporting.

... 125) RECOMMENDATION 7.12  Military reliability, availability, and maintainability testing should be informed and guided by a new battery of military handbooks containing a modern treatment of all pertinent topics in the fields of reliability and life testing, including, but not lim ited to, the design and analysis of standard and accelerated tests, the

... This study covered statistically oriented software engineering methods that were useful for the development of defense systems. RECOMMENDATION 1  Given the current lack of implementation of state-of-the-art methods in software engineering in the service test agencies, initial steps should be taken to develop access to -- either in house or in a closely affiliated relationship -- state-of-the-art software engineering expertise in the operational or developmental service test service agencies.

... This lack of rigorous assessment occurs in the generation of system requirements; in the timing of the delivery of prototype components, subsystems, and systems from the developer to the government for developmental testing; and in the delivery of production-representative system prototypes for operational testing. As a result, throughout early development, systems are allowed to advance to later stages of development when substantial design problems remain.
