The concept of quality information system (QIS)

The product quality characteristics should be the prime drivers when assessing and improving the quality of the software development process as we are concerned with the product quality. The quality of the software product is determined by the quality of the software process. This seems intuitive but there is no empirical evidence to prove its validity yet. QIS establishes a system that enables to analyse the relation between base practices and processes of the SPICE model and the eleven product quality factors and criteria of McCall´s (1977) model for software product evaluation. The main goal of QIS is to evaluate and verify benefits gained by improving the process maturity level. In front line of both, the process model and product quality model is the software product improvement, resulting in a high quality software product delivered on time and at less cost.
