MVP development creates a shippable version that tests one explicit product assumption with real users.
Before sprint one, we document the audience, learning goal, smallest testable scope, measurement points and acceptance criteria. Workshop, prototype and core feature are developed only as far as that decision requires.
Convenience features that do not influence the learning goal stay outside scope, while necessary security, privacy and operational foundations remain part of delivery quality.
Twelve weeks can be a planning scenario for a suitably bounded product after discovery; it is not a blanket delivery commitment. The evidence then supports a conscious decision to scale, refine, pivot or stop.
