Explanation
According to the Project Management Professional (PMP) Reference Materials, the project manager should acknowledge the lack of approval and focus on a resolution that will benefit the customer when a project sponsor is promoting the use of a new technology that has not yet been approved, and the operational support at project completion is uncertain. This is because the project manager needs to balance the interests and expectations of the project sponsor, the customer, and the service organization, and ensure that the project delivers value and quality to the customer. By acknowledging the lack of approval, the project manager can show respect and understanding to the service organization, and avoid further conflicts or risks. By focusing on a resolution that will benefit the customer, the project manager can work with the project sponsor and the service organization to find a way to implement the new technology without compromising the project scope, schedule, budget, or quality. The project manager can also seek the customer's feedback and approval on the use of the new technology, and ensure that the customer's needs and requirements are met. Acknowledging the lack of approval and focusing on a resolution that will benefit the customer can help the project manager to resolve the conflict in a constructive and collaborative way, and deliver a successful project outcome.
