Abstract :As software applications infuse our day today li fe, reliability becomes a very important factor of the software. In this paper, a new model is propos ed to find the expected software release time using Poisson count process. The testing cost, fault removal co st and risk cost due to uncovered fault codes after the release time are incorporated to obtain an analy tical expression for expected total cost. Numerical illustrations are given for the better understanding of the model
