This setting is used to
ensure that Earned Value is not calculated unnecessarily against
duration based projects or any project where time entry is not being
captured. Since IBM Rational Portfolio Manager uses project baseline
information to provide performance variances that do not rely on Earned
Value metrics, this setting is used to define whether Earned Value
metrics are calculated on a project by project basis and only on those
projects required.
Earned Value in IBM Rational Portfolio Manager can be viewed in two ways:
It also provides the ability to view the information graphically.

The Earned Value header displays the date for which the Earned Value is valid. Since team members continue to enter time past this date, once the earned value has been calculated the EV (BCWPRoll Up ), BAC and EAC remain constant until such time as the background execution has been performed. The AC (ACWP) is updated immediately when additional time is entered and the resulting indices calculations are performed. Since these values are based on up to date EV (BCWP) they may not reflect the current situationRoll Up |
BAC | Budget
at Completion
The sum total of the task or project time-phased budget |
Sum of the assignment baseline effort * assignment baseline cost |
ETC | Estimate to Complete | BAC - ACWP (BAC - AC) |
EAC | Estimate
at Completion
The expected total cost of an activity or project when the defined scope of work is completed |
ACWP + ETC (AC + ETC) |
ACWP (AC) | Actual Cost of Work Performed (Actual Cost) | Sum of the (assignment actual regular effort * assignment actual regular cost ) + the sum of (assignment actual special effort * assignment actual special cost ) |
BCWS (PV) | Budgeted Cost of Work Scheduled (Planned Value) | Accumulated weekly baseline work in hours * Baseline hourly rate |
BCWP (EV) | Budgeted Cost of Work Performed (Earned Value) | Current task level percent complete (%C) * BAC |
VAC (CVAC) | Variance
At Completion (Cost
Variance At Completion)
The difference between the budget at completion less the estimate at completion |
BAC - EAC negative result indicates the task or project is over budget |
SV | Schedule
Variance
The difference between the scheduled completion of an activity and the actual completion of that activity |
BCWP - BCWS (EV - PV) |
CV | Cost
Variance
The difference between the estimated cost of an activity and the actual cost of that activity |
BCWP - ACWP (EV - AC) |
SPI | Schedule
Performance Index
The ratio of schedule efficiency that indicates the percent of work performed out of the total work scheduled |
BCWP / BCWS (EV / PV) A number less than 1 indicates that the project is behind schedule. |
CPI | Cost
Performance Index
The ratio of cost efficiency or value earned per unit actual cost. A number less than 1 indicates that the project is spending more money than budgeted |
BCWP / ACWP (EV / AC) A number less than 1 indicates that the project is spending more money thRoll Up an budgeted. |
