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: 7.3 Determine Budget
Definition: The process of aggregating the estimated costs of individual activities or work packages to establish an authorized 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.

7.2.2.9 Vendor Bid Analysis
Cost estimating methods may include analysis of what the project should cost, based on the responsive bids from qualified vendors. When projects are awarded to a vendor under competitive processes, additional cost estimating work may be required of the project team to examine the price of individual deliverables and to derive a cost that supports the final total project cost.
Process: 7.2 Estimate Costs
Definition: The process of developing an approximation of the monetary resources needed to complete project activities.
Key Benefit: The key benefit of this process is that it determines the amount of cost required to complete project work.
