An owner estimate cost model: Testing for medium software projects

One of the most crucial factors for software project managers is determining the project s cost before the project is executed. Likewise, for clients, the price offered to third parties should neither be too high nor too low. Therefore, they need a method or model to determine the correct cost or price for a software project. In a previous study, we have proposed an owner estimate cost (OEC) model for a software project on which small scale. The model has had three parts: personnel direct cost (PDC), non-personnel direct cost (NPDC), and taxes. The PDC was obtained by applying the use case points (UCP) method that has been developed. Originally, UCP was a method of calculating effort for software projects. In this study, we tested the model using a medium-scale software project to know the consistency of the model. The test results show that the model tested is acceptable.
