Why a product design phase comes before the build budget
A product design phase is four to six weeks of structured work sitting between an approved idea and a committed build budget. It produces a validated prototype, a prioritised feature breakdown with ranged estimates, a technical architecture with integration risk resolved, and a release plan with cost scenarios attached. The output is not a set of design artifacts. It is a narrower cone of uncertainty, and a scope that can be cut without breaking. Teams that skip the phase rarely save the money. They move it into the build, where it gets spent on rework nobody planned for.
