  Optimum software release time problem has been an interesting area of
research for several decades now. We introduce here a new concept of
size-biased modelling to solve for the optimum software release time. Bayesian
approach is used to solve the problem. We also discuss about the applicability
of the model for a specific data set, though we believe that the model is
applicable to all kind of software reliability data collected in a discrete
framework. It has applications in other fields like oil exploration also.
Finally, we compare favourably our model with another similar model published
recently. We also provide in this article some future possibilities of research
work.
