If value is "taken" only as 50% and 100% (or other common values such as 25/75. 60/40, etc.), then the EV data will be what you want. John Project MVP

If you have long duration tasks relative to the duration of your project, then you will have unreported value being earned, but actual expenses acruing, throwing off your EV.

Dave, It depends on what you mean by "relatively short". In our case any tasks that were greater than one month but less than three months (yeah that's something like two isn't it), could have a 50/50, 25/75, or 40/60 earned value method (we used monthly statusing/reporting). And yes, such discrete EV methods do throw a skew into the overall data but it balances out. I might add that this method is used and preferred on many Government contracts. John

The more Tasks that you create, and the shorter their durations, the more control and accuracy you obtain and the less you need to be concerned about monitoring and reporting fractions of task completion. You could settle on "no finer level of progress reporting than 50% completion" but if you make enough tasks which are indivually short enough you can happily adopt "no finer level of progress reporting than 100% completion" without acquiring too much over/under reporting error in a given period. What doesn't get picked up this month will get picked up next month (or next week). See the Tracking Toolbar. It is already set for 0, 25%, 50%, 75%, 100%.
