What you get at the end of a product design phase
In the way we run it, a product design phase ends with nine deliverables: a user story map, an estimated feature breakdown, a release plan, a prototype of the primary journeys, design system foundations, technical architecture documentation, a recommended team capacity, a cost and timeline projection and a summary for budget holders. Other companies structure the phase differently, so the list is a reference point rather than a standard. Each deliverable has a test a buyer can run before the final presentation, and the prototype, which gets the most attention in that meeting, says the least about whether development can start.
