Preface—Reliability and Maintainability

Demystifying Maintainability * 1. Assessing Maintainability 1.1 Myths

Due to its economic impact “maintainability” is broadly accepted as an important quality attribute of software systems. But in contrast to attributes such as performance and correctness, there is no common understanding of what maintainability actually is, how it can be achieved, measured, or assessed. In fact, every software organization of significant size seems to have its own definition of ...

Deening and Measuring Maintainability

Maintainability is a measure of the ease with which a software system can be maintained. In this paper we propose a quantitative deenition of maintainability, and discuss means to estimate the maintainability of a software system on the basis of a static analysis of its deliverables. Such an estimation eeort is useful inasmuchas it allows us to predict the maintainability of a software system a...

Requirem nts Risk and Maintainability

In order to continue to make progress in software measurement as it pertains to reliability and maintainability, we must shift the emphasis from design and code metrics to metrics that characterize the risk of making requirements changes. By doing so we can improve the quality of delivered software, because defects related to problems in requirements specifications will be identified early in t...
