7.3.3.1 Cost Baseline
The cost baseline is the approved version of the time-phased project budget, excluding any management reserves, which can only be changed through formal change control procedures and is used as a basis for comparison to actual results. It is developed as a summation of the approved budgets for the different schedule activities.
Process: 7.4 Control Costs
Definition: The process of monitoring the status of the project to update the project costs and managing changes to the cost baseline.
Key Benefit: The key benefit of this process is that it determines the cost baseline against which project performance can be monitored and controlled.

4.4.1.5 Work Performance Information
Work performance information is the performance data collected from various controlling processes, analyzed in context, and integrated based on relationships across areas. Thus work performance data has been transformed into work performance information. Data in itself cannot be used in the decision-making process as it has only out-of-context meaning. Work performance information, however, is correlated and contextualized, and provides a sound foundation for project decisions.
Work performance information is circulated through communication processes. Examples of performance information are status of deliverables, implementation status for change requests, and forecasted estimates to complete.
