Case Study: EDS Uses Actual Results To Calibrate Estimates

Systems integrators live and die by the accuracy of their project estimates. To improve ad hoc estimation methods that were producing inaccurate results, EDS began capturing actual project data in a central repository and trained estimators to consult the repository as a standard part of the estimating process. Sixty-five percent of projects now come in within an exemplary 10% of both effort and duration estimates. EDS's repository holds data on over 10,000 projects and provides its estimators with a key resource to make EDS more competitive.
