Explanation
The project manager should help the sponsors and stakeholders create a clear and shared product vision that describes the purpose, features, and benefits of the product. The product vision guides the project scope and provides a common understanding of what the project aims to deliver. The project manager should also facilitate collaboration and communication between the team and the product owner, who is responsible fordefining and prioritizing the product requirements. The team and the product owner should work together to refine and validate the requirements throughout the project, using feedback loops and iterative delivery. This way, the project scope is continuously aligned with the customer needs and expectations, and any changes or uncertainties are managed effectively.
