The project manager should submit a change request to the change control board (CCB) if they realize that the project will not be completed on time due to resource constraints. A change request is a formal proposal to modify any aspect of the project, such as scope, schedule, cost, quality, or resources. A change request must be submitted to the CCB, which is a group of stakeholders who are authorized to review and approve changes. Submitting a change request can help to document the impact of the resource constraints on the project and seek approval for any corrective actions or preventive actions12
