CPC Schedule Intelligence

Automated QSRA

Monte Carlo schedule risk simulation with P50, P70, P80 and P90 completion confidence. Upload your XER, pick a sector-appropriate risk profile or feed it your own LEI history, and see where your project actually lands — plus which activities are driving that outcome.

Upload Your P6 Schedule
Drag and drop your .xer file, or click to browse. Everything runs in your browser — nothing is uploaded to a server.
Uncertainty Basis
Pick a sector profile or fine-tune your own optimistic and pessimistic range. Or let the tool derive the range from your own LEI Tracker history for a data-driven simulation.
Optimistic: -10%
Pessimistic: +30%
Manual Activity Overrides
Set explicit optimistic / most likely / pessimistic durations (in days) for specific activities — these replace the uncertainty basis above for that activity only. Use this for known high-risk items: long-lead procurement, permitting, first-of-kind installs.
Iterations
Completion Confidence
Forecast completion dates at increasing confidence levels — P80 is the industry standard for programme commitment.
Completion Probability Distribution (S-Curve)
Simulated outcomes bucketed by finish date, with cumulative probability line. The dashed line marks the P80 threshold.
Top Schedule Risk Drivers (Criticality Index)
How often each activity sat on the driving path across all simulated outcomes, and the min / likely / max duration (days) the simulation sampled it against — the higher the percentage, the more it controls the project finish date.

Schedule Sensitivity (Tornado Chart)
How strongly each activity's duration correlates with the overall project finish date across every simulated outcome — captures near-critical activities that rarely sit on the driving path but still swing the result.
