Expert software development estimation with uncertainty correction

摘要

Creation of an effective metrics and estimation program is an important but daunting step for the maturing software development organization This paper outlines a roadmap for implemenríng a process that establishes a program that will reap a large portion of the benefits early in the process with a minimum of implementation effort and cost This process includes a mechanism to improve software estimation accuracy as historical data becomes available for more sophisticated methods. Furthermore, we present a practical proposal for software estimation in industry based on software task size, complexity, and uncertainty.
