Assessing Software Reliability Based on NHPP Using SPC

Software reliability in the software development process is an important issue. Software process improvement helps in finishing with reliable software product. In this field, SPC (Statistical process control) is a method of process management through application of statistical analysis, which involves and includes the defining, measuring, controlling, and improving of the processes. In measuring software reliability control charts can be used as efficient and appropriate SPC Tools. The proposed process involves evaluation of the parameter of the mean value function and hence the values of the mean value function at various inter failure times to develop relevant time control chart. In this paper, was proposed a control mechanism, based on time between failures observations using Burr distribution property, which is based on Non Homogenous Poisson Process (NHPP).
