Required Characteristics for Software Reliability Growth Models
Renyan Jiang · 2009
Software reliability growth models are used to estimate and predict software quality. Many software reliability growth models (SRGM) have been developed in the literature. It is a key issue how to appropriately select them since an inappropriate SRGM can give unreasonable prediction. This paper deals with this issue. It first discusses some characteristics for a SRGM to have, then presents five flexible SRGMs, and finally discusses how to determine the best SRGM from a list of candidate models for a given set of data. The usefulness of the suggested models and method are illustrated by a real-world example. The results show that all the suggested models outperform the well-known exponential model in terms of goodness-of-fit and predictive capability.
