The Approach to Estimating Software Quality Based on Cognitive Model

The article studies generally accepted estimation of software quality, which shows its compliance with users’ expectations. The research deals with investigation of software quality and requirements to it and focuses on the fact that software quality depends on its correspondence to GOST R ISO/MEK 25010-2015. It is proposed to use a common model of quality in order to estimate software by analyzing expert appraisals and their aggregation through the mathematic tool of cognitive maps. The use of cognitive maps gives an opportunity to estimate the quality of software product. At the same time we can get a possibility to identify controlled factors of software product quality, affecting which we can increase its target factor of quality. Findings of the research can be used in practice to develop and estimate software quality on different levels of difficulty and specialization.
