Applying software reliability engineering in the 1990s

摘要

This paper reviews the progress in software-reliability sincen1975, and discusses the best tools and practices that can be appliedntoday. The best development practices are recommended herein, fornmanaging the reliability of software. The development ofnsoftware-reliability models and user-friendly tool kits is described.nThese tools allow software-reliability to be measured, tracked, andnimproved to meet the customer-specified reliability. The ability tonmeasure software-reliability promotes development focus, andnconsequently, its improvement. The 1990s have seen much growth in thensoftware content of products. The problems have grown as the softwarenmushrooms both in size and complexity. Further, software is increasinglynimportant in safety critical applications. To counter these concerns,nthere has been a great collective effort to improve the reliability andnquality of software, through better development-focus exemplified by thenSoftware Engineering Institute's Capability-Maturing-Model levels.nSoftware-reliability-engineering has shown best practices for developingnand measuring software-reliability. The 1990s have brought collectivenfocus on managing reliability. Such collaboration has been in packagingnsoftware-reliability models in user-friendly packages such as SMERFS andnCASRE
