Although it has become widely accepted in software development engineering that quality assurance – and thus software testing – is essential, the application of the concept of software reliability as a relevant quality criterion has apparently not yet been established. The aim of this work is therefore to provide an insight into the basics and concepts of software reliability. For this purpose, basic concepts and background information from software development and software testing will be

Subsequently, important probability distributions in this context and the maximum likelihood principle are presented and applied. Finally, two NHPP models are considered and discussed. Thereby difficulties with their use can be identified. On the one hand, model assumptions are problematic in terms of their implementation in practice, on the other hand, the application – from the selection of an appropriate model via data acquisition through to the estimation of reliability – proves to be extensive and complex.
