Progress Calculation

I think you have understood correctly.  "MS Project is calculating the progress based on duration only."  In MSP,  "% Complete" is always the ratio (Actual Duration)/(Duration), where (Actual Duration) = (Duration - Remaining Duration).  You can't change this.

So if you work for 5 days on a task with Duration=10 days, %Complete = 50%.  But if you work another 2 days before realizing that you have underestimated the time required to do the work by a factor of 2, now you have worked 7 days and have 13 days remaining; your %Complete is therefore 7/20=35%.  Backward progress!

If you are serious about using MSP for earned value reporting, then you should be using Physical %Complete, not %Complete.  Or better yet, measure and report earned value progress using other tools.

Good luck, tom

Another hint:

Change activty type to fixed work.

In field Work put your relative weight for all activities (Depending on project type: M/H, etc)

Input progress of activities in field % Work Progress (Don't use activity % )

Then your duration does not anymore depend on %

Hope it helps
