The project manager should choose option A. Create a prioritized backlog and define iteration review sessions with stakeholders. In a project where the scope is frequently changing due to new knowledge, it’s important to have a flexible and iterative approach. Creating a prioritized backlog allows the team to focus on the most important tasks first. Regular iteration review sessions with stakeholders ensure that everyone is aligned on the project’s progress and any changes to the scope. This approach allows for continuous feedback and adjustment, which can help prevent misunderstandings and ensure that the project outcomes meet business goals. Remember, the goal of project management is to deliver value to the stakeholders, and this approach helps ensure that the project is always aligned with their needs and expectations. It’s not just about scheduling meetings or creating detailed plans, but about creating a flexible and responsive project management process.
