DT088 Earned value parameter: TAR

DI059626 Planned costs (PC)

Cumulated planned costs of the task resource up to the time of creation of the selected status report. 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 duration of the project. As a result, you receive a planned budget in the project at a particular point in time. This budget may then be used up by this point in time. 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 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 earned value analysis.

Details

Actual costs are all costs of the project that have incurred by a particular date.

DI059576 Earned value (EV)

Calculated earned value (completion value) of the task resource.

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 of the project

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 smaller than 1 are bad since the earned value is lower than the actual costs (e.g. CPI = 0.75). Such values show that the work of the task resource will be more expensive than planned.

DI059577 Schedule performance index (SPI)

Calculated schedule performance of the task. 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 (PC)
- Values greater than 1 mean that the task resource completes its work faster than initially planned.
- Values smaller than 1 indicate a delay.

DI059621 Cost variance (CV)

Calculated cost deviation of the work of the task resource

Calculation

Cost variance (CV) = Earned value (EV) - Actual costs (AC)

DI059620 Schedule variance (SV)

Calculated deviation of the schedule of the task. 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)

DI059583 Work progress

Here, the work progress of the task resource calculated by the program is displayed in percent.

Information

The work progress is the basis on which the earned value is calculated.

Calculation

Work progress = Actual costs * 100 / Total costs

Note

The corresponding data field is hidden by default but the user can unhide it if required.

059624 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
