Can Functional Size Measures Improve Effort Estimation in SCRUM
Valentina Lenarduzzi, Davide Taibi · 2014
Abstract—In SCRUM projects, effort estimations are carried out at the beginning of each sprint, usually based on story points. The usage of functional size measures, specifically selected for the type of application and development conditions, is expected to allow for more accurate effort estimates. The goal of the work presented here is to verify this hypothesis, based on experimental data. The association of story measures to actual effort and the accuracy of the resulting effort model was evaluated. The study shows that developers ’ estimation is more accurate than those based on functional measurement. In conclusion, our study shows that, easy to collect functional measures do not help developers in improving the accuracy of the effort estimation in Moonlight SCRUM.
