Where'd my float go!?
Have you worked on project schedules where the progress updates are looking great and close to the planned finish date, only to then go off the rails? What happened?
Michael speaks with Tyler Konter from Point Construction to discuss forensic analysis techniques like bifurcation and half-step analysis to dive deeper into the schedules to find out what's really going on.

Is it just me, or the bifurcation analysis would never be possible for 99.9% of the schedules because schedulers status their projects WHILE ALSO adjusting durations, lags, and dates, and wouldn't save a 2nd version of the same schedule with the same data date to have a progress vs. revision for every update?

Hi Sir - Good question. The process to split the updates into two copies (Progress and Revisions) is documented in AACE technical papers going back to at least 2016. Search "bifurcated" or "half-step" analysis and you should be able to find a 3-part series I co-authored with several people on how to do this process in P6 (we've also replicated in Microsoft Project and other formats, but there are some differences to the process). The process allows the analyst to understand where the schedule would have been before any revisions were made to the remaining plan, and then understand the net effect of the revisions to the remaining plan. Tyler was discussing one of the outputs for running the process on an actual project. Hope that helps.
