11.1. How Are Tasks Scheduled in a Project?

Applies to:
@RISK 6.7/7.x, Professional and Industrial Editions

We sometimes get questions like, "If I edit the _____ field, what will @RISK will do with the project schedule?"

The answer is that all schedule computations are done by Microsoft Project. In each iteration, @RISK computes the random numbers from your input distributions, ships them to Project, and retrieves the values for @RISK output fields after Project does all the schedule computations. So the schedule computations are exactly the same as if you put those random numbers into the project fields yourself. There are no special rules for computing project schedules, just because @RISK is involved.

For details of project computations, see the Microsoft article How Project schedules tasks: Behind the scenes.
