Teams often use prototype and MVP as if they mean the same thing. They do not. A prototype helps you learn how the product should work and feel. An MVP helps you learn whether the product deserves a place in someone’s routine.
The difference in one view
| Question | Prototype | MVP |
|---|---|---|
| Main job | Test the idea, flow, and interface. | Test a valuable task with real users. |
| Typical output | Clickable screens or a simulated workflow. | A deployed, usable product with a narrow scope. |
| Evidence | People understand and can navigate the experience. | People return, complete the task, or take a commercial action. |
Start with a prototype when the flow is uncertain
- The problem is known but the workflow is unclear.
- Several stakeholders disagree about what the product should do.
- The cost of changing the interface after engineering would be high.
- You need to test navigation, language, or interaction patterns first.
Move to an MVP when value is the question
Move on when you trust the basic flow and need proof that the product earns a place in the user’s routine. At that point, the question is no longer ‘can they use it?’ It is ‘will they keep using it, recommend it, or pay for it?’
Do not use either to avoid a decision
A prototype that never reaches a user is expensive theatre. An MVP with every possible feature is a disguised full build. Set one learning goal, one audience, and one decision date before you start.
"A prototype answers, Can they use it? An MVP answers, Will they keep it?"
