Abstract:Software quality models are a well-accepted means to support quality management of software systems. Over the last 30 years, a multitude of quality models have been pro- posed and applied with varying degrees of success. De- spite successes and standardisation efforts, quality models are still being criticised, as their application in practice ex- hibits various problems. To some extent, this criticism is caused by an unclear definition of what quality models are and which purposes they serve. Beyond this, there is a lack of explicitly stated requirements for quality models with re- spect to their intended mode of application. To remedy this, this paper describes purposes and usage scenarios of qual- ity models and, based on the literature and experiences from the authors, collects critique of existing models. From this, general requirements for quality models are derived. The requirements can be used to support the evaluation of ex- isting quality models for a given context or to guide further quality model development.
