Abstract

Look for the continuous improvement of the effort estimate precision can drive the organization to improve its capacity do carry out its commitments, delivering its software products on time and, therefore, bring competitive advantage. We argue that defining a framework of characteristics that impact on software project productivity can improve comparison between finished projects and the new ones that need an effort estimate. This article presents an approach to effort estimate with continuous improvement of the estimates. It is also presented an application of this approach.

Keywords: Continuous Improvement, Effort Estimation, Software Development
