Ranger for Microsoft® Project


Ranger is an inexpensive tool that allows you to understand risk on your projects. Built on the idea of range-based estimating, Ranger lets you use ranges to accurately estimate project effort (work) and project duration. Then, with a simple click, calculate effort uncertainty or duration uncertainty. Best of all, it works with your Microsoft Project files (2002-2003). (Ranger for Microsoft Project 2007 is coming soon!)
