DT089 DT872 EVA: Task

DI059615 Planned costs (PC)

Cumulated planned costs of the task up to the time of creation of the selected status report (PC means Planned Cost). The value stems from the baseline status report (plan).

The planned costs are defined at the beginning of a project and are distributed throughout the entire duration of the project. As a result, at a particular point in time in a project, you get a planned budget that must have been used up by then. If these costs are exceeded, the total budget may be exceeded by the end of the project (source: Wikipedia).

Notes

• In PLANTA project, the term Planned costs is only used for the Earned Value Analysis. In project planning, planned costs are named Remaining/Planned Costs.
• I.e., in PLANTA project the initially planned remaining/planned costs of the task that were “frozen” in the baseline report serve as planned costs.

DI059614 Actual costs (AC)

Cumulated actual costs of the task (AC means Actual Costs). The value stems from the released status report that is used for the Earned Value Analysis.

Details

• Actual costs are all costs of the project that incur by a particular date.

DI059609 Earned value (EV)

Calculated earned value (completion value) of the task (EV means Earned Value)

Calculation

• Earned Value (EV) = Planned Costs (PC) up to the calculated end of the task * Work Progress of the task

Note

• Planned costs at the task end are the Planned costs (PC) cumulated over the entire time of the task.

DI059611 Cost performance index (CPI)

Calculated cost performance index of the task (CPI means Cost Performance Index)

Calculation

• Cost Performance Index (CPI) =Earned Value (EV) / Actual Costs (AC)
  • Values greater than 1 are good, since the earned value exceeds the actual costs (e.g. CPI = 1.2). Such values indicate cost savings.
  • Values less than 1 are bad, since the earned value is lower than the actual costs (e.g. CPI = 0.75). Such values show that the task will be more expensive than planned.

DI059610 Schedule performance index (SPI)

Calculated schedule performance index of the task (SPI means Schedule Performance Index). The Schedule Performance Index is used to evaluate how far the project is from the planned target in terms of time.

Calculation

• Scheduled Performance Index (SPI) =Earned Value (EV) / Planned Costs (PC)
  • Values > 1 mean that the project proceeds faster than initially planned.
  • Values < 1 indicate a project delay.

DI059613 Cost variance (CV)

Calculated cost variance of the task (CV means Cost Variance)

Calculation

• Cost Variance (CV) = Earned Value (EV) - Actual Costs (AC)

DI059612 Schedule variance (SV)

Calculated deviation of the schedule of the task (SV means Schedule Variance). A negative schedule variance indicates that the schedule for the entire project cannot be met.

Calculation

• Schedule variance (SV) =Earned Value (EV) / Planned Costs (PC)

DI059623 OLE SPI/CPI

Traffic light for SPI/CPI codes. The traffic light signalizes whether the task is delayed or whether the costs for the task are greater than planned or not.

Values

• Red traffic light: CPI or SPI < 1
• Green traffic light: CPI and SPI > = 1
• No traffic light: no CPI/SPI values available
