The Earned Value tab enables you to specify default settings for calculating earned value.
Technique for computing performance percent complete
Activity % Complete: Choose to calculate earned value according to current activity completion percentages.
Use WBS Milestones: Choose to calculate earned value by defining milestones at the WBS level and assigning a level of significance or weight to each of them. As progress occurs and you mark each milestone complete, the WBS element's performance percent complete is calculated based on the weight of the milestone.
0/100 % Complete: Choose to calculate earned value as 100 percent only after the activity ends.
50/50% Complete: Choose to calculate earned value as 50 percent after the activity starts and until the activity ends. After the activity ends, the activity's earned value is 100 percent.
Custom% Complete: Choose to calculate earned value as a percentage you specify. This percentage applies after the activity starts and until the activity ends. After the activity ends, the activity's earned value is 100 percent.
Technique for computing Estimate To Complete (ETC)
ETC = remaining cost for activity: Choose to calculate Estimate to Complete (ETC) values as the remaining cost to complete an activity (ETC = remaining duration of activity * applicable resource rates).
ETC = PF * (Budget at Completion – Earned Value Cost), where
PF = 1: Choose to calculate Estimate To Complete (ETC) values as a Performance Factor (PF) of 1 multiplied by Budget At Completion (BAC) less Earned Value Cost.
PF = 1/Cost Performance Index: Choose to calculate Estimate To Complete (ETC) values as a Performance Factor (PF) of 1 divided by the Cost Performance Index (CPI).
PF = 1/ (Cost Performance Index * Schedule Performance Index): Choose to calculate Estimate To Complete (ETC) values as a Performance Factor (PF) of 1 divided by the product of the Cost Performance Index (CPI) and Schedule Performance Index (SPI).
PF =: Choose to calculate Estimate To Complete (ETC) values as a Performance Factor (PF) you specify multiplied by Budget At Completion (BAC) less Earned Value Cost. If you choose this option, type a factor in the PF field.
Earned value calculation
When calculating earned value from a baseline use
Choose to use the baseline's At Completion values and current dates, budgeted or planned values with planned dates, or budgeted or planned values with current dates when calculating earned value from a baseline.
The current dates options use the Start/Finish dates for an activity or resource assignment.
A preference setting (Project Details, Settings tab) controls, per project, the baseline that is used to calculate earned value: the project baseline or each user's defined primary baseline.
Tip
- You can change the earned value settings for specific WBS elements in the Work Breakdown Structure window.
