First up:
Liquid Planner. We saw this product at Demo 2008 but it will be on stage again at the
Under the Radar conference that I'm moderating on Thursday. This tool's special sauce is its embrace of uncertainty. Users can put in best-case and worst-case estimates for their tasks, and the product combines all the estimates to tell you how likely you are to make deadlines, and also which sub-tasks are the most critical to achieving project goals.
