Abstract: The half-step analysis method segregates and quantifies schedule progress and revisions on an update-by-update basis. The power of the method lies in the ability to assess the performance of a plan (progress) and how that plan changed (revisions) over project time, providing a unique understanding of a project’s evolution. For example, a project milestone could be losing progress on a monthly basis, yet the project milestone could appear to be making as-expected progress if the contractor minimized the progress loss by revising the remaining schedule activities.
Two prior Technical Papers, CDR.2305 and PS.2491, provided macro-level examples of how this method could be used to better understand a project both during and after its completion. This paper will explain how to perform a half-step analysis using Primavera P6 in a step-by-step fashion and using clear graphics. The process to complete the half-step analysis is simple; however, there are options and steps that must be followed to ensure an accurate bifurcation result. As with most successful analyses, the “devil” is in the details.
After demonstrating how to progress a schedule, the paper will also demonstrate how to analyze schedule revisions, and more importantly, critical schedule revisions. Finally, the paper will cover real-life applications of the half-step analysis on multiple projects, both for a monthly schedule review and a forensic schedule analysis.
