A photo-grab of the primary critical path of the schedule being analyzed before the start of the SQRA is shown below.
This is the project’s primary critical path generated from Primavera that can be used in contrast to the quantified criticality resulting from running a schedule quantitative risk analysis. The latter provides a semblance of dynamic criticality brought about by multiple simulation and iteration. I call the criticality result of schedule quantitative risk analysis (SQRA) as dynamic critical path (criticality index).
The critical paths from SQRA are in reality, more dynamic in nature than static. Multiple iteration demonstrates the changes a schedule undertakes after each task is updated. It means activities, specially those with high criticality can switch paths, with some ending up as non-critical.
What one can glean from a P6 deterministic schedule at a given time are static critical paths. It is essentially just a snapshot of the paths in time. That snapshot is equivalent to a singular iteration run using our risk analysis tool such as OPRA or Acumen Risk. Never rely on static path with blind confidence. It is best to regularly crosscheck with periodic schedule risk analysis.
