Software Reliability Model Metrics: Precision and Robustness

Software reliability is the key factor among the characteristics software quality, and it is also the important index that hard to control and measure. On the basis of introducing the mechanism of software reliability models, this paper summarizes the present situation of the shortage of the generalization of the model. And it introduces two kinds of software reliability metrics. With the classification of software reliability of software life cycle, it will provide a useful criterion for the effective selection of software reliability. At last, it presents the conclusion and introduces the future work.
