Prediction of Optimum release time of software ensuring high achievable reliability

IEEE Standard 729 [1] defines the reliability of software as one of the most important quality aspects. Various software reliability growth models have been simulated for analyzing the growth of software reliability and it has been observed that a particular model is suitable for particular industry. During this study, we implemented Weibull model, Exponential model, Rayleigh SRGM model and Musa model in MATLAB to analyse data in graphical representation so that comparison can be done efficiently. Initially industries recognize the model that is appropriate for them. Knowing the customer is also very important. Once they came to know their customer's expectations and best- suited model, it becomes very easy to estimate the earliest delivery time. The objective of this paper is to predict optimum release time of software ensuring high achievable reliability because delay in release may lead to business opportunity loss. To ensure that software must be released on time with desired level of reliability, team leaders need to allocate human resources, time and money accurately for that project.
