Project Management Question of the Week

In a project to install last generation automatic elevators, the main deliverable and the test results were sent to the client to get his formal approval.  However, 25 days have passed and the client is nowhere to be found.  The project manager has tried to communicate with the client many times, but he is not returning phone calls.  What is the best thing to do?

• Stop the project until the client formally approves the deliverables.
• Request general management's assistance.
• Ask the client why is he not returing the calls.
• Document the facts in the issues log.
