 According to the PMBOK Guide, the project manager is responsible for managing the project work according to the project management plan and implementing approved changes1. If the project manager discovers that the blueprints received from the client appear incomplete, the first thing to do is to consult with the client to determine if project execution should be continued or if changes are needed. The client is the source of the project requirements and the ultimate authority on the project scope2. The other options are not the best actions for the project manager to do first. Rescheduling the project execution date is a change that requires a formal change request and approval from the change control board3. Continuing project execution using the current blueprints from the client may result in rework, waste, or defects if the blueprints are not accurate or complete4. Escalating this issue to the project sponsor is not the first step, as the project sponsor is not the owner of the project requirements or scope. References:
