CAPM Practice: Determine how to document project controls of predictive, plan-based projects

Control Costs is the project management process of monitoring project costs, updating the cost baseline when approved, and managing changes to the cost baseline. It involves calculating EVM metrics (EV, AC, CV, CPI, EAC) to measure performance and identify variances requiring corrective action. The other options are planning processes.

**Why not A:** Estimate Costs is a planning process that develops cost approximations for project activities. It occurs before execution and produces cost estimates that feed into budget determination. It is not focused on controlling costs during project execution.

**Why not B:** Plan Cost Management establishes how costs will be planned, structured, and controlled throughout the project. It creates the cost management plan — the framework for cost control — but is itself a planning process, not the execution-phase control process.

**Why not D:** Determine Budget aggregates individual activity cost estimates into an authorized cost baseline. It is a planning process that establishes the baseline against which Control Costs will later measure actual performance. It does not actively control costs during execution.
