The Activity Metrics of the General Tab will tell you everything you need to know about the progress of any of your individual Activities to date simply by selecting the Activity in the Gantt Chart. Here is how SmartPM calculates all of these Metrics and what the numbers tell you:
Activity Total Planned Man Hours – This figure shows the Total Planned Man Hours that are planned to be expended in completing the Activity. This figure is based on the Total Man Hours shown in the Activity Attributes or the figure submitted in the Total Man Hours field when the Activity was created
Percent Complete – This figure is representative to the Percent Complete entered in the most currently submitted Field Report for the Activity
Earned Man Hours – This calculation shows how many Man Hours should have been expended based on the Activity’s Percentage Complete compared to the listed Planned Man Hours. In other words, it is an indication of how many of the Activity’s Budgeted Planned Man Hours should have been spent to have achieved the Actual Progress.
- The calculation is the Activity’s Total Planned Man Hours multiplied by the Activity’s Actual % Complete
Actual Man Hours - This will show the sum total of Man Hours submitted via Field Reports for the Activity
Performance Index - This is the average performance index across the entire project. It is equal to the sum of all earned man hours identified for all complete or ongoing activities in the Project Schedule divided by the sum of all Actual Man Hours identified for all complete or ongoing Activities in the Project Schedule.
- The calculation is the Activity’s Earned Man Hours divided by the Activity’s Actual Man Hours
Duration Variance – This metric is simply a ratio comparing the Activity’s Actual or Projected Duration to the Original Planned Duration.
- The calculation is 1 – ((Actual/Projected Duration) / (Original Duration)), expressed in a percentage
Project Original Planned Man Hours - This is the sum of all Planned Man Hours recorded for all Activities entered into the entire Project
Project Current Estimated Man Hours- This is a projection of how many Man Hours will actually be expended over the duration of the Project based on historical data. The calculation is Project Original Planned Man Hours divided by Manpower Performance Index
