Usually a project manager will drop into MS Project and later emerge with the project plan. I saw a nice counter example today where someone acknowledged the uncertainty of a dynamic project situation. ‘We can go off and build what we think you want for the lowest price in the shortest time and plan time to revise it. Or we can do a more conventional project and we’ll place the end date in a four-week time span.‘ Not a hard launch date, but a span of time when they’d probably be finished. Nice.
