| Achieving high software quality, in particular high reliability, is vital for the competitiveness in today's world. The problem investigated by this research is how to design the process for developing software with given quality requirements, in order to achieve product requirements while maintaining the balance between software quality, project cost, and delivery time. The solution proposed here is to develop a framework for customizing a project by selecting software reliability engineering practices for achieving specified software reliability requirements, and modeling the resulting process in order to assess, by simulation, the impact of these practices on project cost, schedule and software quality throughout the development life cycle. The framework is implemented by a decision support system (DSS) for software reliability engineering strategy selection and assessment. This dissertation describes the framework, presents the methodology used for developing it, as well as framework implementation and the results of using the fuzzy expert system for strategy selection and the system dynamics process simulator for practices effect evaluation. |
