Software Reliability Model Selection Criteria:A Literature Review

Computer systems are booming exponentially and their correct functioning has become extraordinarily critical. Software reliability is the most dynamic quality characteristic which can measure and predict the operational quality of the software system during its intended life cycle. Software reliability models (SRM) are used for the estimation and prediction of software reliability. Although there are many SRM suggested and studied to estimate software reliability measures such as the number of remaining faults, software failure rate, and software reliability. However, selection of an optimal SRM for use in a particular case has been an area of interest for researchers in the field of software reliability. In this paper, we have identified and defined a number of criteria for software reliability model selection. We will also throw light on issues why despite having plethora of SRM, none of them are valid at all times and there is no unique model which can perform well for all situations.
