possibly one of the best kept secrets amongst Project Management tools, RiskyProject is currently delivered as a desktop application that actually maintains the Project Schedule and Risk Register in the same place and allows the Project Manager to model the probabilistic schedule based on risk exposure, mitigants and probabilities.

RiskyProject Professional is engagedprojects tool of choice as it combines Project Planning with a Risk Register to provide Quantitative Risk Analysis. It integrates with Microsoft Project, Primavera and other PM Tools.

engagedprojects uses  MindManager to provide an initial Critical Path or Event Chain netwoirk that is then ported to RiskyProject, updated with the Schedule and Task Risks from the Risk Register to alllow a Monte Carlo analysis to be carried out.

There is bidirectional integration with MS Project if required; however RiskyProject is more than good enough for the Planning, Risk Management, Analisys and Tracking of most projects.

better still RiskyProject allows the modeling of uncertainty - it's a great product that needs a serious look...

engagedprojects is a licenced reseller of the RiskyProject toolset.
