For a project that must deliver value incrementally, what should the project manager do to enable successful execution?

The question asks what a project manager should do for a project that must deliver value incrementally. Creating a project schedule with milestones is crucial because milestones represent significant points in the project lifecycle where value can be demonstrated or delivered. This aligns directly with an incremental delivery approach, allowing for regular checks on progress and value realization. Identifying tangible and intangible benefits is part of project justification and business case development, not the primary mechanism for enabling incremental execution. Engaging the project sponsor to understand scope is a foundational activity but doesn't specifically address the incremental delivery aspect. Developing a comprehensive set of requirements is important, but in an incremental context, requirements are often refined and delivered in smaller batches rather than a single, comprehensive upfront document.
