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

A Control Account is a management control point at a specific level of the WBS where scope, schedule, and cost are integrated and compared for performance measurement (using EVM). Each Control Account has a designated Control Account Manager (CAM) responsible for its performance. Control Accounts roll up to the total project performance measurement baseline.

**Why not A:** A summary of approved change requests is maintained in the change log, not a control account. Control accounts are performance measurement structures within the WBS, not change management records.

**Why not B:** Accounting records for vendor payments are part of the organization's financial or accounts payable system. Control accounts in project management are management control points for performance measurement, not financial accounting instruments.

**Why not D:** A control account is not a bank account. The term "account" in this context refers to a management control point in the WBS where scope, schedule, and cost converge for earned value measurement — not a financial institution account holding project funds.
