Project Ranger v3.1 for Microsoft® Project

Ranger is an inexpensive tool that allows you to understand risk on your projects.


Ranger is built on the idea of range-based estimating. With Ranger you can range-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).
