Before a change request is presented to the change control board, which of the following should the project manager do?

Asking the board to study the cost shifts the PM's analytical responsibility onto the reviewers, which is contrary to the PM's duty to prepare a complete change request package.

The PM is responsible for assessing the full impact of a proposed change on scope, schedule, cost, quality, risk, and resources before the CCB review, ensuring the board has complete and accurate information to make an informed approval or rejection decision - this is the core of the integrated change control process.

Reviewing the change with the project sponsor is not a required prerequisite step before the CCB, as the CCB is the formal governance body designated to evaluate and authorize changes.

Soliciting team input on the value of a change is not the PM's primary pre-CCB task; the PM's role is to conduct and present an objective impact assessment, not to gather value opinions.
