A startup PO has limited budget and needs to validate whether their target segment will use a new expense tracking feature. The FASTEST low-cost experiment is:
Answer: Create a fake door test: add the feature button to the UI and measure click-through before building it
A fake door (or 404) test measures genuine interest by tracking clicks on a feature that doesn't yet exist, at near-zero development cost.
Which statement BEST reflects the Scrum framework's stance on assumption validation?
Answer: Scrum's inspect-and-adapt cycles and Sprint Reviews provide natural checkpoints for validating product assumptions
Scrum's empirical pillars — transparency, inspection, and adaptation — inherently support ongoing assumption validation through short feedback loops.
A PO assumes that reducing checkout steps from 5 to 3 will increase conversion. After shipping the change, conversion drops. What is the MOST likely explanation?
Answer: An underlying assumption (e.g., that removed steps caused friction rather than building trust) was incorrect
Unexpected results often reveal that a hidden assumption about user psychology or behavior was incorrect, requiring further investigation.
What does 'desirability testing' specifically validate in the context of product assumption validation?
Answer: Whether users actually want the product or feature and perceive it as valuable
Desirability testing focuses on the user dimension — confirming that real users want the solution and find it valuable enough to adopt.
A PO is conducting assumption validation experiments during a sprint. How should this work appear in the Sprint Backlog?
Answer: As explicit Sprint Backlog items with a clear hypothesis, test method, and success criteria
Making experiments explicit Sprint Backlog items with defined success criteria keeps validation work transparent and actionable for the whole team.
When a PO presents assumption validation results at a Sprint Review, what is the stakeholders' PRIMARY role?
Answer: To provide additional context, surface related assumptions, and help interpret the evidence
Stakeholders bring domain knowledge and business context that enriches interpretation of validation results and helps surface further unknowns.
A PO documents the following: 'We believe [users] will [perform this action] because [reason]. We will know this is true when [measurable outcome].' This is an example of:
Answer: A hypothesis statement format for structured assumption validation
This structured hypothesis format ensures assumption validation experiments are specific, testable, and tied to measurable outcomes.
