A prototype is a model of a product used to explore or communicate an idea, often with simulated functionality. An MVP is a working product, small in scope, that people actually use, so you can learn whether your core assumption holds. Prototypes answer 'does this make sense?'; MVPs answer 'will people actually use it?'
When to prototype
- Stakeholders cannot picture the idea
- You need feedback on a workflow or interface
- Several design options must be compared quickly
When to build an MVP
- The concept is understood but demand is unproven
- You need evidence that people will change behaviour or pay
- The core action can be delivered with a small, reliable product
Limitations and considerations
- Positive prototype feedback does not prove people will use the product.
