1-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 activitys 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 activitys earned value is 100 percent.
2- 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 units 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.
3- Earned value calculation
When calculating earned value using a primary baseline use
- Budgeted values: Choose to use the primary baselines budgeted values for earned value calculations.
- At Completion values: Choose to use the primary baselines At Completion values for earned value calculations.
