PMBOK Agile and Hybrid Methodologies 4 â Questions and Answers
Question 1: A hybrid project manager is deciding which elements to manage using predictive vs. agile approaches. Which factor MOST strongly favors using a predictive approach for a component?
- The team is co-located and highly collaborative
- Requirements are well-defined, stable, and unlikely to change (Correct answer)
- Stakeholders want frequent delivery of working features
- The technology stack is new and not well understood
Correct answer: Requirements are well-defined, stable, and unlikely to change
Predictive approaches work best when requirements are well-defined and stable, allowing detailed upfront planning without costly rework from changing scope.
Question 2: What is the purpose of a 'spike' in agile development?
- A sudden increase in velocity during a high-performing sprint
- A time-boxed research task to reduce uncertainty or answer a technical question (Correct answer)
- A rapid deployment to production to test a hypothesis with real users
- An emergency backlog item added during a sprint due to a critical bug
Correct answer: A time-boxed research task to reduce uncertainty or answer a technical question
A spike is a time-boxed exploratory task used to investigate an unknownâwhether technical, design, or businessâso the team can estimate or proceed with greater confidence.
Question 3: In a Scrum framework, who is responsible for maximizing the value of the product resulting from the Scrum Team's work?
- Scrum Master
- Product Owner (Correct answer)
- Development Team
- Project Sponsor
Correct answer: Product Owner
The Product Owner is accountable for maximizing the value of the product and managing the Product Backlog, including ordering items to best achieve goals.
Question 4: Which agile concept describes delivering the smallest possible product that allows a team to validate a hypothesis with real users?
- Minimum Viable Product (MVP) (Correct answer)
- Minimum Marketable Feature (MMF)
- Walking Skeleton
- Tracer Bullet
Correct answer: Minimum Viable Product (MVP)
A Minimum Viable Product (MVP) is the smallest product with enough features to satisfy early adopters and gather validated learning for further development.
Question 5: During a daily standup, a team member says they have no impediments and their work is on track. What should the Scrum Master do?
- Challenge the team member to commit to more work for the day
- Accept the update and ensure the standup stays time-boxed (Correct answer)
- Require the team member to detail every task completed yesterday
- Skip that team member to save time in future standups
Correct answer: Accept the update and ensure the standup stays time-boxed
The Scrum Master should accept the update and ensure the daily standup remains time-boxed to 15 minutes, as it is a planning event for the Development Team, not a status report.
Question 6: What is the key difference between 'adaptive' and 'predictive' life cycles according to PMBOK?
- Adaptive projects always cost more than predictive projects
- Adaptive life cycles change scope as more is learned, while predictive life cycles fix scope early (Correct answer)
- Predictive projects are limited to software development only
- Adaptive projects do not require stakeholder engagement
Correct answer: Adaptive life cycles change scope as more is learned, while predictive life cycles fix scope early
Adaptive (agile) life cycles embrace scope changes throughout the project, whereas predictive (waterfall) life cycles fix scope, time, and cost early in planning.
Question 7: A team is using Scrum and realizes mid-sprint that the sprint goal is no longer achievable due to a fundamental change in business direction. What should happen?
- The team extends the sprint until the original goal is met
- The Product Owner can cancel the sprint if the goal becomes obsolete (Correct answer)
- The Scrum Master unilaterally decides to end the sprint early
- The team completes whatever items they can and reports a failed sprint
Correct answer: The Product Owner can cancel the sprint if the goal becomes obsolete
Only the Product Owner has the authority to cancel a sprint if the Sprint Goal has become obsolete, after which a new Sprint Planning event begins.
