Abstract: When updating a critical path method (CPM) schedule, calculating remaining durations based on remaining original duration versus remaining work duration, provides profoundly different information. Updating in-progress activities based on remaining original duration can more accurately quantify the impact of a delay or acceleration, whereas progress based on remaining work can more accurately show the cause of delay. Thus, both are important to calculate. When using remaining original duration, progress is linear, which allows calculations to be accurately broken down to the unit day. This provides a continuity and a trajectory over time, which can be used to anticipate delays before their occurrence, allowing mitigation measures to be considered and put in place. This paper examines the differences between the two updating methods, providing simple examples of how the two methods of updating can provide insights on different aspects of a forensic schedule analysis.
