PMBOK Agile and Hybrid Approaches 2 — Questions and Answers
Question 1: In Scrum, what is the primary purpose of the Sprint Retrospective?
- Review completed user stories with stakeholders
- Inspect and adapt the team's processes and practices (Correct answer)
- Prioritize the product backlog for the next sprint
- Demo working software to the product owner
Correct answer: Inspect and adapt the team's processes and practices
The Sprint Retrospective focuses on continuous improvement by having the team inspect how they worked and identify process improvements.
Question 2: Which agile metric measures the amount of work a team completes in a single iteration?
- Burn rate
- Velocity (Correct answer)
- Lead time
- Cycle time
Correct answer: Velocity
Velocity measures the amount of work (story points or items) a team completes per sprint and is used for release planning.
Question 3: In a hybrid project, a project manager uses a waterfall phase for regulatory approvals and an agile phase for development. What is the BEST reason for this structure?
- Agile cannot handle regulatory requirements at all
- Waterfall is always faster for approval processes
- Different parts of the project have different levels of uncertainty and constraints (Correct answer)
- Hybrid approaches always outperform pure agile or waterfall
Correct answer: Different parts of the project have different levels of uncertainty and constraints
Hybrid approaches allow teams to apply the methodology best suited to each project phase based on uncertainty, risk, and stakeholder needs.
Question 4: What does 'Definition of Done' (DoD) represent in agile frameworks?
- The acceptance criteria for a single user story
- A checklist of quality standards that must be met for work to be considered complete (Correct answer)
- The sprint goal defined by the Scrum Master
- The product owner's sign-off on delivered features
Correct answer: A checklist of quality standards that must be met for work to be considered complete
The Definition of Done is a shared understanding of the quality criteria and conditions that must be satisfied before any increment is considered complete.
Question 5: A product owner is struggling to balance stakeholder requests with team capacity. Which agile technique BEST helps manage this challenge?
- Increase the sprint length to accommodate more work
- Maintain a prioritized product backlog and say no to lower-value items (Correct answer)
- Ask the Scrum Master to resolve all stakeholder conflicts
- Add more developers to the team immediately
Correct answer: Maintain a prioritized product backlog and say no to lower-value items
The product owner's core responsibility includes maintaining a prioritized backlog and making tough trade-off decisions about what gets built.
Question 6: In the Scaled Agile Framework (SAFe), what is a Program Increment (PI)?
- A single sprint within one agile team
- A fixed timebox (usually 8-12 weeks) in which multiple agile teams deliver value (Correct answer)
- The total budget allocated for a release train
- A quarterly review meeting with senior executives
Correct answer: A fixed timebox (usually 8-12 weeks) in which multiple agile teams deliver value
A Program Increment is a SAFe timebox of 8-12 weeks during which Agile Release Trains deliver incremental value in the form of working, tested software.
Question 7: Which statement BEST describes the agile principle of 'sustainable pace'?
- Teams must work overtime when deadlines approach
- Teams should work at a pace they can maintain indefinitely without burnout (Correct answer)
- Velocity should increase by 10% each sprint
- Project managers should maximize team utilization to 100%
Correct answer: Teams should work at a pace they can maintain indefinitely without burnout
Agile promotes sustainable development where sponsors, developers, and users maintain a constant pace indefinitely, avoiding burnout and quality degradation.
