Software Development Effort Estimation based-on multiple classifier system and Lines of Code

The development effort estimation is one of the most difficult problems in software project management. It is one of the most critical aspects in the early stages of the software project. Several software development effort estimation models have been proposed, however, these models are not able to obtain more than a 25 percent of accuracy, neither provide an understandable model for experts in the application area. Therefore, in this paper, we present EEpred, an explanatory model to estimate the development effort based on data of known software projects. It is a serial multiple classifier system based-on several decision trees. The model performance was evaluated by an internal validation procedure, analyzing their robustness and predictive performance. This procedure demonstrates that EEpred is able to estimate the software development effort with a 71 percent of precision. The main advantage of EEpred, regarding to other algorithms, is its ability to translate the process into a collection of simple decision rules, providing more easily interpretable knowledge that can help software engineer to improve decision-making on development planning.
