After you have completed the baseline estimate, you can create a revised version of the baseline using the Estimate to Complete (ETC) view in the Integrated Planning window. The ETC view is identical in look and feel to the Baseline view. Changes you make to the ETC do not change the baseline estimate, making it possible to compare current estimates to the original baseline estimates.
The original monthly baseline estimate data is automatically maintained by MPM to provide performance measurement of the baseline plan. Baseline and ETC dates are displayed in various Gantt and Time Analysis reports.
When you have created the ETC, MPM can use it to:
Generate Estimate to Complete reports
Generate Latest Revised Estimate (LRE) reports
Graph LRE data in Graphic Drill Down (GDD)
Calculate Estimate at Completion (EAC) reports
There are two ways to create the ETC:
You can save the resources estimates to the ETC as you create the Baseline.
You can copy the Baseline estimates to the ETC using the Project Replan function
Estimating completion costs is described in Revising the Forecast (ETC).
