Software Quality Models: A Comparative Study

Abstract

Software quality is the totality of features and characteristics of a product or a service that bears on its ability to satisfy the given needs. Software quality model is the representation of the characteristics of the software that describe the quality. The benefit of quality models is that they are simpler to use and the benefit of quality management is that they probably more to the point capture the idea of quality. So the quality of the project should be maintained at appropriate label. To maintain the quality, there are different quality models. "A high quality product is one which has associated with it a number of quality factors. These could be described in the requirements specification; they could be cultured, in that they are normally associated with the artifact through familiarity of use and through the shared experience of users. In this paper, we will compare all the quality models: McCall’s quality model, Boehm’s quality model, Dromey's quality model, and ISO 9126 quality model and focus on a comparison between these models, and find the key differences between them.
