Specifics of Quality Assessment Models Application at Development and Use Stages of Software Systems

The article examines the peculiarities of applying quality models at different stages of development and utilization of software systems to ensure their high quality. The main aim of the research is to identify new combined approaches for evaluating the effectiveness and impact of quality models usage at various stages of software product life cycles. The work employs a systematic approach to analysis, considering the interaction of quality models with different stages of software design, development, testing, and operation. Specifically, the role of quality models in enhancing the efficiency of development processes and their impact on the final product quality is discussed. The methodology involves analyzing existing quality models, adapting them to specific project conditions, and studying practical examples of quality model implementation in real projects. An analysis of existing quality models, their adaptation to specific conditions of software system projects, and an analysis of implementation in real projects are carried out. This approach has enabled us to obtain specific results and reveal key aspects of quality model implementation. The interaction of quality models with overall quality assurance strategies and their impact on improving the productivity and reliability of software systems is considered. In a general scientific aspect, the research boils down to evaluating the effectiveness of this approach and determining its key features. Further examination showed that the use of new combined quality models in the stages of design, development, and testing contributes to the improvement of various aspects of software quality. They not only define quality criteria but also ensure compliance with these criteria throughout the project life cycle. The obtained results confirm the importance of using combined quality models at all stages of software development. This contributes not only to the improvement of the final product quality but also to the efficiency of the entire development process. Our results can serve as a basis for the practical implementation of quality models in software projects and improving the overall quality level in this field.
