Model Quality Assessment in Practice: How to Measure and Assess the Quality of Software Models During the Embedded Software Development Process

International audience ; In this paper we present an approach for assessing the quality of model-based software projects. We demonstrate this approach in embedded software projects in the automotive domain. Our methodology can however be extended to other fields of software development. In general, the quality assessment of software projects is often based on quality criteria such as maintainability, testability, readability of the software or the software model. Our approach expands this basic assessment in that we assess the quality of a project on the basis of the success or degree of realization of quality operations (testing, reviews, etc.) respectively. Furthermore, we do not focus on single artifacts of the development process (e.g. model or code); rather we take all relevant development artifacts into account and use their interrelations to obtain metrics and key figures. We demonstrate our approach using our tool, Model Quality Assessment Center (MQAC), which was expressly developed for this purpose.
