WBS Earned Value Detail Window of the Activities Page

Overview

Use this detail window to configure the technique for computing earned value components including the Performance Percent Complete and Estimate to Complete (ETC) for the selected WBS. Earned Value cost is the portion of the planned total cost of the activity that is actually completed as of the project data date; it is calculated as:

Earned Value =Performance % Complete x Budget At Completion (BAC)

The method for computing the Performance Percent Complete depends on the earned-value technique you select for the activity's WBS.

Note: To view WBS detail windows, group your view by all levels of the WBS.

Screen Elements

Technique for computing performance percent complete section

The options for computing the performance percent complete.

Activity Percent Complete option

Determines whether to calculate earned value according to current activity completion percentages.

Use resource curves/future period buckets option

Determines whether to use resource curves or future period buckets in the calculation of earned value instead of using current activity completion percentages.

When selected, this setting overrides the Activity Percent Complete type for activities that have a resource curve assigned to at least one of the resource assignments, or for activities that have assignments with manually-defined future period bucket values. If a curve is assigned, Units Percent Complete is always multiplied by the Budget at Completion to calculate earned value.

WBS Milestones Percent Complete option

Determines whether to calculate earned value based on the completion of weighted WBS milestones.

As progress occurs and you check off each completed milestone, the WBS element's performance percent complete is calculated based on the weights of the milestones.

For example, if four WBS milestones are weighted 2.0, 1.0, 1.0, and 1.0, and you mark the first one completed, the percent complete would be set to 40%.

0/100 option

Determines whether to calculate earned value as either 0 or 100 percent. An activity's performance percent complete remains 0% until it is completed and then its percent complete is set to 100%.

50/50 option

Determines whether to calculate performance percent complete as either 50 or 100 percent. An activity's performance percent complete remains 0% until it is started and then its percent complete is set to 50%. When the activity is complete, its percent complete is set to 100%.

Custom percent complete option

Determines whether earned value is calculated based on a percentage you specify between 0 and 100. This percentage applies after the activity starts until it ends. After the activity is completed, its percent complete is 100%.

Technique for computing Estimate to Complete (ETC) section

The options for computing the Estimate to Complete (ETC).

ETC=remaining cost for activity option

Determines whether to calculate ETC values as the remaining cost to complete an activity.

The remaining cost is calculated as the remaining duration of an activity in units of time multiplied by its applicable resource rates in units of currency.

ETC=PF * (Budget at Completion - Earned Value) option

Determines whether ETC is equal to a performance factor (PF) multiplied by (Budget at Completion minus Earned Value). If you select this option, you must select one of four options to set a value for the performance factor:

PF=1: The performance factor will equal 1. This method yields an optimistic result with ETC equal to the Budget At Completion (BAC) minus Earned Value Cost.

PF=1/Cost Performance Index:The performance factor will equal 1 divided by the Cost Performance Index (CPI), where the CPI = Earned Value Cost divided by Actual Cost. This method yields the most likely result.

PF=1/(Cost Performance Index * Schedule Performance Index): The performance factor will equal 1 divided by the Cost Performance Index multiplied by the Schedule Performance Index (the Earned Value Cost divided by the Planned Value Cost). The equation can be interpreted as: PF equals 1 divided by (EVC divided by AC) multiplied by (EVC divided by PVC). This method yields a pessimistic result.

PF=<value>: The performance factor will equal a value you specify. If you select this option, enter a factor in the field.

Tips

If you have more than one WBS selected, the detail window will not be visible.
