Fixed-Price, Fixed-Outcome MVPs: How to Avoid Scope Creep and Missed Deadlines

The operating model that gets founders to market on time: fixed price, clear outcomes, tight scope control, and weekly demos that keep momentum.

Scope creep kills timelines. A fixed-price, fixed-outcome model keeps teams aligned and shipping.

The Model

  • Fixed budget and deadline
  • 3 feature cap with explicit acceptance criteria
  • Weekly demos; anything not demoed is not “done”

Controls

  • One change request meeting per week
  • “Later list” for good ideas that threaten scope
  • Feature flag non-essentials
  • MVP timeline: /blog/mvp-development-timeline-2025-two-to-four-weeks
  • The 7-page spec: /blog/seven-page-product-spec-for-fast-mvp-builds

Predictable delivery is a process choice, not a personality trait.
