PSPO I: Product Discovery & Validation practice questions
20 questions on Product Discovery & Validation, one of the 7 areas assessed in Professional Scrum Product Owner I. Untimed, with an explanation after every answer.
This topic covers how a Product Owner tests assumptions before investing heavily: hypotheses, experiments, spikes, prototypes, fake door tests and the Minimum Viable Product. Discovery is ordinary Product Backlog work that can run alongside delivery. Test first the assumptions that gate a large investment, lack evidence and are cheap to check.
The minimum in MVP refers to scope, never quality: anything released to users meets the Definition of Done. Stated preference, even unanimous or from a senior stakeholder, is a hypothesis, not evidence. A disproved hypothesis is a successful experiment. Decide in advance which result would disprove it, and never rerun a test until the answer suits you.
A Product Owner is confident that a proposed feature will increase retention, but has no evidence. Which is the most appropriate next step?

Mock examA worked example
A question from the bank with its answer and the reasoning behind it. Every practice question comes with an explanation like this one.
Stakeholders in a workshop unanimously agree that a proposed capability is essential. What weight should a Product Owner give this agreement?
- ADecisive — unanimous stakeholder agreement is the strongest available evidence
- BLimited — stated preference in a workshop is a weak predictor of real behaviour and should be tested(correct answer)
- CNone — stakeholder opinion is irrelevant to ordering
- DDecisive if the stakeholders include the most senior executive present
Why
Stated preference and revealed behaviour routinely diverge, and unanimity in a room often signals shared assumptions rather than validated need. The input is genuinely useful for shaping what to test, but it is a hypothesis, not a result. Neither unanimity (A) nor seniority (D) converts opinion into evidence, and dismissing stakeholders entirely (C) discards valuable context.
