Project Cost Management includes processes for planning, estimating, budgeting, and controlling costs throughout a project. The key processes are:
1. Plan Cost Management to establish policies and procedures for managing project costs.
2. Estimate Costs by developing approximations for completing project activities.
3. Determine Budget by aggregating activity cost estimates to establish a cost baseline.
4. Control Costs by monitoring costs, identifying variances from the baseline, and managing changes to keep costs within approved limits.
