Function of Progress Analysis
If you want to effectively control your project, you need to do more than individually studying costs, resources, and schedules. You can draw informed conclusions on the progress and current status of your project only when you compare these values with actual results. Progress analysis enables you to do this. This analysis is suitable for both internal control of a project and external reporting.
You can estimate the POC of WBS elements, activities, and activity elements. You can also calculate POC automatically using existing data. In both cases, a planned POC (expected progress at a specific point in time) and an actual POC (progress actually made at a specific point in time) are determined. By specifying a weighting factor (planned costs, for example), you can aggregate these values in the WBS.
The system uses a factor, such as planned costs, to calculate progress values from POCs:
BCWS: budgeted cost of work scheduled (costs according to planned progress)
BCWP: budgeted cost of work performed (target costs according to actual progress)
Actual costs: costs actually incurred
Comparing earned values provides important information. By comparing BCWS with BCWP, you can determine any deviations from the schedule (for example, if the project is progressing too slowly). By comparing the BCWP with actual costs, you can determine any cost variances (for example, if the project is too expensive).
You can store earned value analysis in a separate plan version and evaluate it using the structure information system or controlling information system.
