Discovery: Problems Worth Solving
Continuous discovery, user interviews that avoid leading questions, jobs to be done, opportunity solution trees, assumption mapping and the riskiest assumption, cheap experiments (fake doors, prototypes, concierge), and using support tickets and data as discovery inputs.

Outcomes, opportunities and jobs
Discovery is the work of reducing value risk before building. Teams that skip it ship features on time that move nothing.

the outcome
Start from a measurable outcome the business cares about, not a feature: the Letter of Non-Indebtedness generates 249 manual support issues a month; halve them.

Interviews and assumption tests
interviewing without leading
- Ask about specific past behaviour: "Tell me about the last time you needed a clearance letter." Not "Would you use…?"
- Follow the story: what triggered it, what they tried, what was hard, what it cost them.
- Do not pitch your idea; you will hear politeness, not truth.
- Talk to five to eight people per segment before drawing conclusions; record and share clips.
| assumption type | example | cheap test |
|---|---|---|
| desirability | customers want letters in the app | fake-door button; count taps |
| usability | they can find and download it | clickable prototype, five users |
| feasibility | balances are accurate in real time | an engineering spike against the ledger |
| viability | receiving banks accept QR verification | call two partner banks |
