A General Approach of Quality Cost Management Suitable for Effective Implementation in Software Systems

Abstract

Investments in quality are best quantified by implementing and managing quality cost systems. A review of various opinions coming from practitioners and researchers about the existent quality cost models reveals a set of drawbacks (e.g. too theoretical and too close to ideal cases; too academic, with less practical impact; too much personalized to particular business processes, with difficulties in extrapolating to other cases; not comprising all dimensions of a business system). Using concepts and tools in quality management theory and practice and algorithms of innovative problem solving, this paper formulates a novel approach to improve practical usability, comprehensiveness, flexibility and customizability of a quality cost management system (QCMS) when implementing it in a specific software application. Conclusions arising from the implementation in real industrial cases are also highlighted
