Index Performance Portlet of the Workspace PageOverview Use this portlet to view the schedule performance index (SPI), cost performance index (CPI), and to complete performance index (TCPI) calculations. Use the status indicators to help you gauge whether these index values are within an acceptable range or whether you will need to take corrective action, based on thresholds you define. Screen Elements Legend Key to performance threshold indicators. Use these visual indicators to quickly scan values based on thresholds you define:
Schedule Performance Index (SPI) field A measure of the work accomplished as a percentage of the work scheduled. SPI indicates whether you are meeting earned and planned values within your schedule. You can set performance thresholds for SPI calculated values to determine whether you need to take corrective action. Calculated as: Earned Value of Cost or Quantity divided by Planned Value of Cost or Quantity The variance percentage is calculated as: Earned Value divided by Planned Value. Cost Performance Index (CPI) field A measure of the value of work accomplished as a percentage of the actual costs of a project. CPI indicates whether you have spent money over the budget to date. You can set performance thresholds for CPI calculated values to determine whether you need to take corrective action. Calculated as: Earned Value divided by Actual Cost Where: Actual Cost equals actual equipment cost plus actual expense cost plus actual work cost plus actual material cost The variance percentage is calculated as: Earned Value divided by Actual Cost. To Complete Performance Index (TCPI) field A measure of the value of the project work that is remaining. TCPI is essentially a ratio of the remaining work to the remaining funds. It helps determine the level of performance that must be achieved on the remaining work to meet recognized business goals, such as the Budget at Completion (BAC) or the Estimate at Completion (EAC). You can set performance thresholds for calculated TCPI values to display visual indicators that help you determine whether you need to take corrective action. Calculated as: (BAC minus Earned Value) divided by (EAC minus Actual Cost or Units) Where: BAC equals base equipment cost plus base expense cost plus base work cost plus base material cost; EAC equals (actual equipment cost plus actual expense cost plus actual work cost plus actual material cost) plus (remaining equipment cost plus remaining expense cost plus remaining work cost plus remaining material cost); Actual Cost equals actual equipment cost plus actual expense cost plus actual work cost plus actual material cost Tips The Index Performance portlet data is derived from your choice of cost or labor units.
