Have you ever used an online collaboration app for a Microsoft Project file (.mpp)? 2017-03-22T20:03:01-04:00 SGT Private RallyPoint Member 2440796 <div class="images-v2-count-0"></div>I&#39;m asking because I just found out about Seavus Project Viewer, Gantter, and ProjectPlan365.

This was a purchased program loaded on my employee PC. It was good to gather info, track, costs, tasks, time, and was relatively easy too Learn. However, our PM&#39;s used Primavera, a much more detailed program that is very expensive and requires taking classes (seminar) to learn to use effectively. I attended a three day seminar for Primvera users, but did not use it daily, therefore was NOT very good as the Projest Managers who lived and breathed this program. Project Management tracking is an important task required for large and mega projects generally done by a smal team of people who understand the thousands of tasks involved in both engineering and construction.
