Assumptions Are Risks
Every product idea rests on assumptions — about the user, the problem, the solution, and the market. The riskiest assumptions are the ones that, if wrong, would make the entire product fail. Discovery prioritises testing these first.
Experiment Types
- Fake door test — measure demand before building
- Concierge MVP — deliver the service manually to validate value
- Wizard of Oz — simulate automation with human effort behind the scenes
- A/B test — compare two variants with real users
Key Takeaway
Test your riskiest assumption first with the cheapest experiment possible.
