A customer indicates that they would like to add a functionality to a product in development. Although this request is made during the execution stage of the project, the project manager determines that the cost for the addition would be small. The additional functionality, if successful, would increase the opportunity for profit. What should the project manager do next?

Question $3$ options:

Move forward, using the projects management reserve to add the requested functionality

Submit a change request and then evaluate the impact to the project.

Identify and already$-$developed feature that could be combined with the new functionality, and use the combination to meet the customer's request.

Acknowledge that the functionality would offer a great opportunity, but determine that the proposed addition is out of scope.

Add it to the product backlog for future refinement.
