Project schedule & cost Monte Carlo
Native CPM + Monte Carlo engine — the model a desktop MS-Project add-in will feed. Durations and lags are in working days (per the work-week calendar); dependencies support the four link types with lag (e.g. D:SS+5, C:FF-2), plus task constraints and deadlines. Edit the tasks, costs and risk register, then simulate.
Joint confidence level — target convergence
Pick a probability of meeting BOTH the finish date and the budget together. iziRisk iteratively raises both targets over the last simulation’s joint distribution until that joint confidence is reached — giving you the date and budget to commit.

Correlated inputs — bands that move together
Two estimates made the same way by the same team, or two rates driven by one market, do not move independently. Pair them and say how strongly (−1 to 1). A band in no pair is drawn exactly as before.
