Software Quality Tradeoffs, Return on Investment, and Software Safe ty

摘要

In this paper, we discuss what we believe is the grand challenge facing the software quality research community: the ability to accurately define, in the very earliest stages of development, the techniques that will be needed to achieve the needed levels of what we consider to be the key non-functional attributes: reliability, availability, fault toleran ;e, testability, maintainability, performance, software safety, and software security. We will further explore the associated technical and economic tradeoffs that must be made in order to achieve quality and to also certify software quality. Also, we will ;ake into account the fact that satisfying a particular level of each attribute requires specific cost expenditures, and account for attribute conflicts.
