Improving quality model construction through knowledge reuse

Abstract

Software quality models provide a framework to measure and evaluate software quality of software systems. They are the basis upon which classify requirements and may be eventually used to guide the quantification of these requirements, especially non-functional requirements. Lots of approaches for building quality models have been proposed in the last decades, but still their reuse along different projects is a challenge. In this paper we present several types of knowledge repositories and reuse processes to bridge this gap. The approach implements the idea of software factory and uses some well-known standards and notations like ISO/IEC 25010 as quality standard and the i? framework to codify knowledge patterns. We will illustrate how this reusebased approach helps in obtaining composite quality models for systems that integrate several software components with an individual quality model each.
