Abstract: Windows analysis is one of the more effective and widely accepted methods of conducting forensic schedule analysis. Creation of a mid-period, or progress-only, schedule is essential to effective Windows analysis, in that it separates the effects of progress on the critical path from the effects of revisions to the network, thereby isolating causes of delay from efforts meant to mitigate those delays. AACE's Recommended Practice for Forensic Schedule Analysis outlines methods for creating mid-period schedules; however, Primavera Version 6 has introduced a wide variety of new functions which, while beneficial to project managers during construction, may cause problems with the creation of mid-period schedules during delay analysis. As a result, there is a risk that the advanced global features of enterprise scheduling software, like P6, can introduce errors into the created schedules. In addition to making recommendations for best practices in creating mid-period schedules, this paper will examine the risks and potential sources of error, through case studies, and make recommendations for tracking, mitigating, or eliminating risks associated with the creation of mid-period schedules.
