An MVP brief that makes development estimates comparable
Define users, workflows and acceptance criteria so proposals describe the same release.
Two estimates can look very different because they describe different products. Before comparing prices or dates, give each builder the same account of who the first release serves, what it must do and what is intentionally outside the scope.
- 01
Begin with a concrete scenario. For example: a small agency receives a client request, assigns an owner and lets the client see progress. Name the actors and their permissions. Explain whether the client needs an account, whether attachments are essential and whether an administrator can correct a mistake. These details change the implementation more than a broad label such as dashboard.
- 02
Describe the expected result of each step. A request should appear once even if the submit button is pressed twice. A client should see only their own requests. Closing a request should preserve its history. Such examples give a developer something to verify and give the founder a way to accept the work.
- 03
List dependencies separately: existing customer data, email delivery, payment access, design assets and an external system that must be connected. State who will supply each item. A short development estimate is not a launch commitment if the team is waiting for access to an essential service.
- 04
Include an explicit later list. Team-level reporting, several languages and a mobile app may be valuable, but moving them outside the first acceptance boundary makes the initial proposal easier to compare. A proposed shortcut should also name its operational cost, such as manually approving the first accounts.
- 05
Finally, ask each proposal to identify assumptions, handover materials, support boundaries and the process for changing scope. Compare an example change request across proposals: what happens if clients need a second role? An estimate becomes decision-ready when it explains the release you receive and the work required to keep it usable afterward.
