This research aims to investigate the accuracy of time estimates made during the planning and progress of activities in a systems development project.
Conducted a historical analysis of time estimates from contractors on a systems development project.
Tested two hypotheses regarding the timing of activity estimates and their accuracy.
Developed models to adjust estimates based on the estimator's past performance.
Found that accuracy of time estimates improves as the start date approaches.
Observed that estimates become more accurate as completion dates come nearer.
The results serve as preliminary evidence of the feasibility of the proposed methods for improving time estimates.
