Abstract In this study, we discuss a framework for software reliability growth modeling with a change of testing-environment for improving the accuracy of the reliability assessment based on software reliability growth models, and develop specific NHPP (nonhomogeneous Poisson process) models based on our modeling framework based on typical NHPP models. Finally, we investigate usefulness of our proposed models by conducting goodness-of-fit comparisons with corresponding existing models by using actual data. Further, we derive a software optimal release policy, which are interesting issues in software development management based on our proposed models.
