The Integrated Delay Theory (IDT) is an innovative approach to project delay analysis that addresses limitations in traditional scheduling practices.
IDT brings a delay analysis framework that improves upon conventional methods by integrating both forensic properties and stochastic causal modeling from Graphical Path Method (GPM) schedules. IDT challenges the reliance on deterministic schedules, especially contemporaneous ones used during project execution, which often fail to accurately predict actual completion dates when delays occur.
Instead of using outdated predictive schedules in post-completion analysis, IDT emphasizes the use of the Fully Progressed Update (FPU), which contains factual data such as actual durations, dates, and total floats. By leveraging the algorithmic characteristics of FPUs and acknowledging the limited predictive value of deterministic schedules, IDT provides a more accurate and causally sound method for analyzing delays.[/vc_column_text][vc_btn title=”Download the Presentation” style=”outline” shape=”square” color=”black” align=”left” css=”” link=”url:https%3A%2F%2F2023050.fs1.hubspotusercontent-na1.net%2Fhubfs%2F2023050%2FPublications%2FIntegrated%2520Delay%2520Theory%2520Expo%2520USA%25202025%2520Presentation%252003%2520Oct%252025%25202nd%2520Submittal.pdf|target:_blank”][vc_column_text css=””]As presented at the Project Controls Expo, October 7, 2025, Washington, DC[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][/vc_column][/vc_row]
