Retrospective Analysis

Retrospective analyses are performed after the delay event has occurred and the impacts are known. The timing may be soon after the delay event but prior to the completion of the overall project, or after the completion of the entire project. Note that forward-looking analysis (such as ‘additive modeling’) performed after project completion is still retrospective in terms of timing. What is classified here is the real-time point-of-view of the analyst, and not the mode of analysis (forward-looking or hindsight). In other words even forward-looking analysis methods implemented retrospectively have the full benefit of hindsight at the option of the analyst.
