Özet

In this study, we compared the effectiveness of two approaches to effort estimation for organizations utilizing SCRUM. We compared SCRUM's native effort estimation method Story Points and poker planning, with effort estimation models based on COSMIC Function Points (CFP) for a selection of projects. We utilized different regression models and ANN methodology to develop estimation model from the backlog stories. Results indicated that, estimation model built with COSMIC measurement results prove to be a better method for effort estimation than SCRUM's story points.
