Currently the organization has been concerned with the analysis of the impact of IT investments. Economic pressures, combined with years of significant IT spending without demonstrating clear returns, forced companies to improve their financial practices and justify better and more clearly every penny invested way. Thus, this paper presents the model to calculate the return on investment after deploying software. This model was generated from two experiments conducted in the laboratory and in the field, which showed effective action to catch the post-deployment time metrics. Nevertheless, this paper may be applicable to all companies wishing to calculate the temporal return from a deployment.
