CSPO Product Assumption Validation 2 — Questions and Answers
Question 1: A Product Owner identifies an assumption that 'users prefer a mobile-first experience.' Which technique is MOST appropriate for validating this assumption quickly?
- Run a full sprint building the mobile interface
- Create a clickable prototype and conduct usability tests with target users (Correct answer)
- Ask the development team for their opinion
- Wait until the product launches and monitor adoption metrics
Correct answer: Create a clickable prototype and conduct usability tests with target users
A clickable prototype enables rapid, low-cost user testing to validate or invalidate the assumption before significant investment.
Question 2: When prioritizing which assumptions to validate first, a Product Owner should focus on assumptions that are:
- Easiest to test regardless of their importance
- Most risky and have the highest impact on product success (Correct answer)
- Agreed upon by all stakeholders
- Related to technical implementation details
Correct answer: Most risky and have the highest impact on product success
High-risk, high-impact assumptions pose the greatest threat to product viability and should be tested first to avoid wasted effort.
Question 3: A Product Owner discovers that an assumption was wrong after a sprint. What is the BEST response?
- Continue with the original plan to avoid scope creep
- Update the Product Backlog to reflect the new learning and adapt the product direction (Correct answer)
- Blame the stakeholders who provided incorrect information
- Document the finding and revisit it at the next quarterly review
Correct answer: Update the Product Backlog to reflect the new learning and adapt the product direction
Scrum's empirical process requires adapting the backlog and product direction when new evidence invalidates previous assumptions.
Question 4: Which of the following BEST describes a 'Leap of Faith' assumption in product development?
- An assumption that has been validated through user research
- A core belief about user behavior or market need that the entire product strategy depends on (Correct answer)
- A technical assumption made by developers about system performance
- An assumption that stakeholders have formally approved in writing
Correct answer: A core belief about user behavior or market need that the entire product strategy depends on
A 'Leap of Faith' assumption is a critical, unverified belief that underpins the product's value hypothesis and must be tested early.
Question 5: A PO wants to validate the assumption that users will pay a premium for an AI-powered feature. Which experiment type provides the strongest evidence?
- An internal team survey about perceived value
- A smoke test landing page measuring actual payment intent or sign-ups (Correct answer)
- A competitor analysis to see if others charge for similar features
- A Sprint Review demonstration to existing users
Correct answer: A smoke test landing page measuring actual payment intent or sign-ups
A smoke test that captures real payment intent reveals true willingness to pay far better than surveys or secondary research.
Question 6: How does assumption validation relate to the Product Goal in Scrum?
- Assumption validation is only relevant after the Product Goal is achieved
- Validating key assumptions helps confirm whether the Product Goal remains viable and worth pursuing (Correct answer)
- The Product Goal eliminates the need for assumption validation
- Assumption validation is a Developer responsibility, not a PO concern
Correct answer: Validating key assumptions helps confirm whether the Product Goal remains viable and worth pursuing
Testing assumptions about user needs and market conditions continuously informs whether the Product Goal is still the right target.
Question 7: A Product Owner conducts an A/B test comparing two onboarding flows. Group A converts at 12% and Group B at 18%. What should the PO do?
- Run the test for another month to get more data regardless of current results
- Adopt flow B and update the backlog to refine it further based on the validated learning (Correct answer)
- Present both options to the Scrum Team and let them vote
- Defer the decision to the next Program Increment planning session
Correct answer: Adopt flow B and update the backlog to refine it further based on the validated learning
Validated data showing a clear performance difference supports adopting the better-performing option and building on that learning.
