When changes to the project scope are needed, you handle them through a formal process and then authorize the modification with a specific document. The document that actually authorizes and implements the modification is the change order. It captures the new scope, any cost implications, and schedule impacts, and it becomes part of the contract.

The broader framework that governs how changes are proposed, reviewed, approved, and tracked is the change management process. This ensures everyone follows the same steps, maintains documentation, and keeps a clear record of approvals and outcomes.

So, implementing changes relies on issuing a change order within the structured change management process. The other terms don’t fit as the primary instrument: a control account is a budgeting and performance-tracking point, not the authorization document for changes, and a change control board is a governance body that may review changes but does not itself execute the contract modification.
