Creating a Historical Database for Estimation Using the EPCU Approximation Approach for COSMIC (ISO 19761)

In the actual competitive software industry, software development organizations need a better and formal estimation approaches in order to increase the success rate of software projects. However, currently the estimation approach typically employed in industry is the expert judgment ('experience-based'). Using measures and estimations that continue to be based on researchers' intuition does not contribute to obtaining successful projects nor to mature software engineering. Any organization that aims to have or develop estimation approaches needs historical data, and the majority of the organizations do not have this information. Additionally acquisition of this information has expensive cost and time/effort consuming. This paper proposed the use of the EPCU approximation approach-that has demonstrated a several benefits-aiming to create a formal database with low cost and effort, that can be employed as a starting point to improve estimations in organizations without historical databases.
