DT088 DT872 EVA: Task-Resource

DI059626 Planned costs (PC)

Cumulated planned costs of the task resource up to the time of creation of the selected status report (PC means Planned Costs). 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 project that were “frozen” in the baseline report serve as planned costs.

DI059625 Actual costs (AC)

Cumulated actual costs of the completed work (AC means Actual Costs) of the task resource. 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.

DI059576 Earned value (EV)

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

Calculation

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

Note

• Planned costs up to the calculated end of the task resource are the Planned Costs (PC) cumulated over the planning time of the resource in the task.

DI059578 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 resource will be more expensive than planned.

DI059577 Schedule performance index (SPI)

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

Calculation

• Schedule Performance Index (SPI) =Earned Value (EV) / Planned Costs (AC)
  • Values > 1 mean that the task resource completes its work faster than initially planned.
  • Values < 1 indicate a delay.

DI059621 Cost variance (CV)

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

Calculation

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

DI059620 Schedule variance (SV)

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

Calculation

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

DI059624 OLE SPI/CPI

The traffic light signalizes, whether the work of the task resource is delayed or whether the costs for the task resource 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
