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

A work authorization system controls the sequence and timing of work initiation. It ensures that: work begins only when properly authorized; predecessors are complete; resources are available; and the work is within the current approved scope. This prevents teams from working on unauthorized work or starting activities before their predecessors are complete.

**Why not A:** Managing approvals for change requests is the function of integrated change control and the Change Control Board. The work authorization system controls when work begins, not whether changes to the project are approved.

**Why not B:** Authorizing payment of vendor invoices is a financial/procurement administration function. The work authorization system controls the initiation and sequencing of project work, not the payment processing for completed vendor work.

**Why not C:** Authorizing team members to make scope decisions is a governance and authority matter defined in the project management plan. The work authorization system controls work sequencing and timing, not decision-making authority over project scope.
