Explanation
According to the PMP reference materials, a project that is required to deliver value on an incremental basis should follow the agile project management approach12. This approach emphasizes delivering working product frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale3. To enable successful project execution, the project manager should identify the tangible and intangible benefits that each product increment will deliver to the customer and the organization4. This will help the project manager prioritize the product features, plan the iterations, and measure the progress and value of the project4. The other options are not the best actions to take for an incremental project, as they may not align with the agile principles and practices. Engaging with the project sponsor to understand the scope (A) is important, but not sufficient, as the scope may change or evolve based on customer feedback and changing requirements. Developing a comprehensive set ofrequirements (B) is not advisable, as it may lead to over-analysis and delay the delivery of value. Creating a project schedule containing milestones is not consistent with the agile approach, as it may impose rigid constraints and limit the flexibility and adaptability of the project team.
