Project time estimation is difficult to accomplish effectively. Each project has distinctive features and system programming requirements. Therefore, each project has unique time requirements. ITS management can implement several procedures to improve time estimates. For example, additional project detail is needed for accurate estimates.
Time estimates for tasks are more accurate when tasks are clearly defined and restricted in scope.
In addition, realistic project estimates, based on an analysis of project requirements, are not developed in some cases. Subsequently, time estimates are not reviewed and revised periodically. The original project budget hours are not consistently revised to reflect an accurate estimate after a thorough analysis has been conducted. The Information Technology Services Unit should improve project time estimation by including additional detail in project documentation, requiring development of time estimates based upon a thorough analysis of project requirements, reviewing and revising time estimates periodically throughout the project, and reporting and tracking budget and actual time on projects to aid in estimating future projects. The successful implementation of this recommendation is dependent on the full implementation of Enterprise PM anticipated to be completed in December 1995.
