A hybrid project requires a key input from the outcome of another project that uses agile. What should the project manager do next?

The correct answer is to align high-level project timelines with the other project manager. This is a crucial step for managing dependencies between projects, especially when one project's outcome is an input for another. Aligning timelines ensures that the necessary input will be available when the hybrid project needs it, preventing delays and facilitating smooth integration. Participating in daily standups of another project is generally not an efficient use of time for a project manager, as it's too granular and not directly focused on managing the dependency at a strategic level. Asking another project manager to change their delivery methodology is inappropriate and unrealistic; each project uses the methodology best suited for its context. Requesting a WBS from an agile project is also inappropriate, as agile projects typically use backlogs and user stories instead of a traditional WBS.
