Backlog Management PMP Practice Questions

Test yourself with 6 free, scenario-based PMP practice questions on backlog management, drawn from the Process domain of the exam and aligned to PMBOK 8. Work through each scenario before revealing the answer — every question includes an explanation of why the correct choice is right. For randomized, interactive practice across all topics, use the practice question tool.

Question 1 of 6

A product owner has a backlog of 120 items. The team completes 20 stories per sprint. During backlog refinement, the product owner adds 25 new stories every sprint. What is the MOST likely consequence if this pattern continues?

  1. A.The backlog will shrink over time as the team completes more stories
  2. B.The team will naturally increase velocity to match the incoming story rate
  3. C.The backlog will grow without bound, making prioritization increasingly difficult and diluting focus
  4. D.The product will be over-engineered due to excessive feature requests
Show answer and explanation

Correct answer: C

If the team completes 20 stories per sprint but 25 are added, the net backlog grows by 5 stories per sprint. Over time, the backlog becomes unmanageable: old items lose relevance, prioritization becomes harder, and the team loses focus on value delivery. The product owner should regularly groom and prune the backlog — removing low-value items rather than perpetually adding new ones. Velocity rarely grows simply to match demand, and over-engineering is not the primary risk here.

Question 2 of 6

During backlog refinement, the team provides story point estimates using Planning Poker. One developer estimates 8 points; another estimates 2 points for the same story. What should happen next?

  1. A.Average the two estimates to 5 story points, balancing the optimistic and pessimistic views while keeping the sprint planning session on schedule and avoiding analysis paralysis.
  2. B.Accept the higher estimate as a conservative safety margin — this protects the sprint commitment and reduces the risk of incomplete work at the end of the sprint.
  3. C.Let the product owner make the final call on story points, since they own the backlog and best understand the business priority and relative complexity of the story.
  4. D.Ask both developers to explain their reasoning; the discussion often reveals assumptions and complexity that improves the team's shared understanding.
Show answer and explanation

Correct answer: D

Divergent estimates in Planning Poker are valuable signals. The developer estimating high likely sees complexity, risk, or dependency that the lower estimator missed. The discussion surfaces hidden assumptions, technical concerns, and shared understanding — which is the primary purpose of Planning Poker. After the discussion, the team re-estimates with better shared context. Simply averaging loses this insight. Accepting the high estimate is arbitrary. The product owner should not drive technical estimates.

Question 3 of 6

A team's velocity for the last five sprints is: 32, 28, 35, 30, and 33 story points. The product owner wants a forecast of how many sprints it will take to complete the remaining 180 story points in the backlog. What is the BEST forecast?

  1. A.Approximately 5.8 sprints — using average velocity of 31.6 story points per sprint
  2. B.4.5 sprints — dividing backlog by the highest velocity (35)
  3. C.5.5 sprints — using the lowest velocity (28) for a conservative estimate
  4. D.6 sprints — rounding up based on the most recent velocity of 33
Show answer and explanation

Correct answer: A

Average velocity = (32 + 28 + 35 + 30 + 33) / 5 = 158 / 5 = 31.6 story points per sprint. Sprints needed = 180 / 31.6 = 5.7 sprints, rounding up to approximately 5.8. Using average velocity over multiple sprints provides the most statistically reliable forecast. Using only the highest is optimistic, only the lowest is pessimistic, and only the most recent sprint ignores the trend. In practice, a range would be shared: between 5.2 (using 35) and 6.4 (using 28) sprints.

Question 4 of 6

The product owner wants to prioritize backlog items using the MoSCoW method. A 'Should Have' item requires significant development effort but delivers moderate value. A 'Could Have' item takes minimal effort and delights users. How should the product owner handle these?

  1. A.Always deliver 'Should Have' items before 'Could Have' items as a strict rule — MoSCoW creates absolute priority ordering that must be followed sequentially to protect higher-priority commitments.
  2. B.Consider scheduling the 'Could Have' item before or alongside the 'Should Have' if the effort/value ratio is significantly better.
  3. C.Remove the 'Could Have' item entirely since higher-priority 'Should Have' items remain incomplete — MoSCoW rules prohibit scheduling lower-priority work while higher-priority obligations are still outstanding.
  4. D.Let the development team decide based on technical preference — engineers closest to the implementation are best positioned to judge which item introduces fewer technical risks and dependencies.
Show answer and explanation

Correct answer: B

MoSCoW provides a priority framework but should be combined with effort/value analysis. A 'Could Have' item with a far superior value-to-effort ratio may deliver more business value sooner than a high-effort 'Should Have' item. Product owners should use MoSCoW as a guide, not a rigid rule, balancing priority, effort, dependencies, and strategic value. The development team provides effort estimates but value prioritization belongs to the product owner.

Question 5 of 6

What is the PRIMARY purpose of backlog refinement (grooming)?

  1. A.To formally accept or reject completed user stories from the last sprint
  2. B.To identify and eliminate low-priority items from the backlog permanently
  3. C.To add detail, estimate, and prioritize backlog items so they are ready for upcoming sprint planning
  4. D.To create the sprint goal for the next sprint
Show answer and explanation

Correct answer: C

Backlog refinement is an ongoing activity where the team adds acceptance criteria, estimates effort, clarifies requirements, and reorders backlog items so that the top items are 'ready' — well-understood and appropriately sized — before sprint planning. Story acceptance happens in the sprint review. Eliminating items may occur during refinement but is not its primary purpose. The sprint goal is created during sprint planning, not refinement.

Question 6 of 6

A product owner wants to add a technically complex story to the next sprint. The team says the story is not ready because it lacks acceptance criteria and the technical approach is unclear. What should happen?

  1. A.Add the story to the sprint anyway and let clarity emerge during implementation — teams working in short iterations can resolve ambiguity faster in practice than in planning sessions.
  2. B.Conduct a refinement session to add acceptance criteria and clarify the technical approach before committing the story to a sprint.
  3. C.The product owner should write the acceptance criteria independently — they own the requirements and are the authoritative source for what done means before the story enters the sprint.
  4. D.Break the story into smaller parts and add them to the next sprint without refinement — decomposing reduces uncertainty by limiting each piece to a smaller, better-bounded scope.
Show answer and explanation

Correct answer: B

A story is not 'ready' for sprint planning until it meets the team's Definition of Ready — typically including clear acceptance criteria, a shared understanding of the technical approach, and an appropriate size estimate. Adding unrefined stories to a sprint risks failed sprints, rework, and unclear done criteria. Refinement is the appropriate process for clarifying stories before commitment. The product owner and team collaborate on acceptance criteria — it should not be done unilaterally. Breaking into smaller stories is good practice but still requires refinement.
