Is keeping two project plans ever appropriate?

Question

I feel that if I publish a project plan that shows completion on date X, I can't very well push for completion at date (X - 3 weeks). But If I publish a plan that shows date (X-3 weeks), how can I track the "most likely" completion date (which is likely date X)?

Answer 1

You may want to look at a Project Add-in which allows for Monte-Carlo modeling. This will allow you to see probability to reaching completion dates and will allow you to model various scenarios.
