An Insight of software quality models applied in predicting software quality attributes: A comparative analysis

Software is crucial in giving a competitive edge to most of the organizations. Software has become main part of business products, systems and services. Software products quality was seen as a significant element in success of business. The purpose of the research is to the existing models related to software quality which is used for predicting the quality attributes in the software. SQM models selected for this study to compare are ISO 9126, Bertoa, ISO 25010, CBQM and Alvaro model. Main characteristics selected are portability, maintainability, flexibility, usability, reliability and efficiency and sub characteristics are accuracy, testability, extendibility, compatibility, understandability and performance. This study adopts secondary source of data. It was noticed that for the selected set of quality attributes characteristics, Alvaro model excel well in main characteristics as well as other sub characteristics namely understandability, accuracy and testability.
