Metrics, models and measurements in software reliability

Abstract

Reliability is always important in all systems but sometimes it is more important than other quality attributes. Software reliability engineering approach is focused on comprehensive techniques for developing reliable software and for proper assessment and improvement of the reliability. Reliability metrics, models and measurements form an essential part of software reliability engineering process. We should apply appropriate metrics, models and measurement techniques in SRE to produce reliable software, as no metric or model can be used in all situations. So, we should have profound knowledge of metrics, models and measurement process before applying them in SRE. In this paper, we present an in-depth analysis of all metrics, models and measurements used in software reliability.
