Metrics and models for Software Reliability: A systematic review

Software Reliability is an important factor affecting the software quality. Quality measured by counting the number of faults in the program. Software reliability covers a number of relative factors, and these factors have an impact on the software reliability individually as well as collectively also there is no other model that covers all reliability parameters. Another problem is to assign the weightage to these parameters. This paper is focused on the study of different parameters that affects the software reliability and will compare different models used to calculate the software reliability.
