Project Management Question of the Week

In a $23 million real-estate development project with a schedule of 18 months, the project plan has already been developed and approved by the stakeholders.  Later, the client requests to add a change to the project without delaying the estimated due data.  The client is willing to pay more for this change.  What is the first thing the project manager should do?

• Start a new project for the change the client is requesting.
• Estimate contingency plans so the project is not delayed.
• Start the integrated change control process.
• Modify the scope per the client's request and send an invoice for the additional costs.
