CPI vs. TCPI EAC Chart
The CPI vs. TCPI EAC chart on the EAC Realism tab compares, over time, the cumulative or current cost performance index (CPI) and the to-complete performance index (TCPI to EAC). CPI indicates actual cost efficiency to date, and TCPI to EAC indicates the efficiency required in the future to meet the estimate to complete.
Chart Format
By default, the CPI vs. TCPI EAC chart is a line chart, with a separate line for each variance. Use the Fast Change icon (
) to switch to a pivot table that displays the actual values for the data points and enables you to drill down to the period-by-period variances for each element.
