Monte-Carlo schedule risk for P6 & MS Project · ScheduleSignal
See · Schedule Risk

Turn one finish date into a probability.

Monte-Carlo simulation over your real schedule network — triangular uncertainty, per-activity three-point overrides, 500 to 5,000 iterations — gives you P50/P80/P90 finishes, the probability of making the plan, and the activities that actually drive the risk.

Milestone confidence

Not just the project finish — the dates your client asks about.

P50 and P80 dates for the first eight open milestones, plus the probability of meeting the CPM date for the project as a whole.

01

Criticality index

How often each activity sat on the driving path across iterations — your watch list for the month, ranked.

02

Driving path

The deterministic driving path, traced through the CPM engine’s driver tracking — see which chain actually sets the finish.

03

The risk narrative

An auto-written paragraph explaining the distribution and its drivers — ready to paste into the monthly report.

Method, stated plainly

Triangular uncertainty, tuned per activity.

Apply a global range or override any activity with its own three-point estimate. Simulations run 500 to 5,000 iterations, chunked with progress shown. Scheduling is day-granular — documented in Honest limits.
