This inverts the default instinct to open a roadmap conversation with "what are we building."

If I give you the problem, I empower you."
Closing checklist for any roadmap or backlog item: why does it exist, what problem does it solve, how will success be measured, and what evidence exists that it's valuable, usable, feasible, and viable. Feeds into Transitional Roadmap and Outcome-Based Roadmap Reframing.
