質問 # 52
Which phrase best describes a Product Owner?
- A. Requirements engineer.
- B. Go-between development team and customers.
- C. Team manager.
- D. Value optimizer.
正解：D
解説：
The correct answer is B, because a Product Owner is best described as a value optimizer. The Scrum Guide states that "the Product Owner is responsible for maximizing the value of the product resulting from work of the Development Team." Therefore, a Product Owner should focus on delivering value to the customers and stakeholders through the product.
質問 # 53
Which two things should the Development Team do during the first Sprint? (Choose two.)
- A. Develop at least one piece of functionality.
- B. Analyze, design, and describe the complete architecture and infrastructure.
- C. Create an increment of potentially releasable software.
- D. Analyze, describe, and document the requirements for the subsequent Sprints.
- E. Make up a plan for the rest of the project.
正解：A、C
解説：
According to the Scrum Guide, each Sprint is a project with no more than a one-month horizon.
The Sprint Goal gives guidance to why the Scrum Team is building an Increment. The Development Team consists of professionals who do the work of delivering a potentially releasable Increment of "Done" product at the end of each Sprint. Therefore, in the first Sprint, as in any other Sprint, the Development Team should develop at least one piece of functionality and create an increment of potentially releasable software. The other options are not consistent with Scrum values and principles.
質問 # 54

質問 # 55
Who is responsible for tracking the remaining work of the Sprint?
- A. The Development Team.
- B. The Development Team is consultation with the Product Owner.
- C. The Scrum Master.
- D. The Product Owner.
- E. The Project Manager.
正解：A
解説：
According to the Scrum Guide1, only people who are actively working on items in the Sprint Backlog participate in updating it during a Sprint; this includes tracking progress made on those items. This is typically done by Developers updating their remaining work every day after their Daily Scrum. The Development Team tracks this total work remaining at least for every Daily Scrum to project the likelihood of achieving their Sprint Goal.
質問 # 56
Several Sprints into a project, the Product Owner tells the Scrum Master that a key stakeholder just started using the product. The stakeholder is unhappy with the quality of the product, and the Product Owner agrees with the stakeholder's assessment that the quality is low. How should the Scrum Master respond to the Product Owner?
(choose the best two answers)
- A. Explain to the Product Owner that it is up to the Developers to decide on acceptable quality standards.
- B. Bring the concern to the testers to improve how the Product is verified.
- C. Work with the Product Owner to understand their desired resolution and help formulate an approach for raising the concern with the Developers.
- D. Tell the Product Owner they have noted the concern and will raise this issue at the Sprint Retrospective.
- E. Encourage the Product Owner to include quality specifications in the Product Backlog and to communicate the stakeholders ' concerns to the Developers.
正解：C、E
解説：
Several Sprints into a project, a key stakeholder begins using the product and finds the quality lacking. The Product Owner (PO) agrees and shares this concern with the Scrum Master (SM). The Scrum Master needs to determine the best way to respond.
Scrum emphasizes empiricism , which is based on transparency, inspection, and adaptation . This means that if quality concerns arise, the Scrum Team must inspect the issue, adapt accordingly, and ensure quality is built into the product incrementally.
# A. Encourage the Product Owner to include quality specifications in the Product Backlog and to communicate the stakeholders ' concerns to the Developers.
# Reference from the Scrum Guide :
* " The Product Backlog is an emergent, ordered list of what is needed to improve the product. It is the single source of work undertaken by the Scrum Team. "
* " The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. "
# Why is this Correct?
* Since the Product Owner represents the stakeholders , they should translate the stakeholder's concerns into actionable Product Backlog Items (PBIs) that reflect quality improvements.
* Developers can refine and plan these PBIs in upcoming Sprints to ensure quality is systematically addressed.
* The Product Backlog is the single source of work , meaning all quality requirements should be made explicit there.
* This approach aligns with Scrum's empirical process of making work transparent so that the team can inspect and adapt.
# C. Work with the Product Owner to understand their desired resolution and help formulate an approach for raising the concern with the Developers.
# Reference from the Scrum Guide :
* " The Scrum Master serves the Product Owner in several ways, including: Helping find techniques for effective Product Goal definition and Product Backlog management. "
* " The Scrum Master serves the Scrum Team in several ways, including: Helping the Scrum Team focus on creating high-value Increments that meet the Definition of Done. "
# Why is this Correct?
* The Scrum Master is a servant leader , responsible for facilitating collaboration between the Product Owner and Developers so that the concern is effectively addressed.
* Instead of dictating a solution, the Scrum Master guides discussions and enables the team to decide how best to improve quality.
* The Definition of Done (DoD) should be reviewed to ensure it is clear, measurable, and includes quality standards .
* This approach ensures that all stakeholders-Developers, Product Owner, and Scrum Master- collaborate in a self-managing way to improve quality.
Incorrect Answers with Explanations
# B. Bring the concern to the testers to improve how the Product is verified.
# Reference from the Scrum Guide :
* " Developers are always accountable for: Instilling quality by adhering to a Definition of Done. "
# Why is this Incorrect?
* Scrum does not have a separate testing team ; instead, the Developers are responsible for all aspects of quality (coding, testing, integration, etc.).
* Quality should not be " verified " by an external group; rather, it must be built into the Increment from the start .
* Instead of passing the issue to testers, the Scrum Team should improve their Definition of Done to ensure the product meets the necessary quality standards.
# D. Tell the Product Owner they have noted the concern and will raise this issue at the Sprint Retrospective.
# Reference from the Scrum Guide :
* " The Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint. "
# Why is this Incorrect?
* While the Sprint Retrospective is useful for discussing improvements , waiting until the Retrospective delays the resolution of a critical issue.
* The Scrum Team should act immediately by addressing quality issues in the Product Backlog and adapting their work in upcoming Sprints.
* Transparency and fast feedback are key principles in Scrum- delaying discussions goes against empiricism .
# E. Explain to the Product Owner that it is up to the Developers to decide on acceptable quality standards.
# Reference from the Scrum Guide :
* " The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product. "
* " If the Definition of Done for an increment is part of the standards of the organization, all Scrum Teams must follow it as a minimum. "
# Why is this Incorrect?
* While the Developers are responsible for meeting the Definition of Done , quality is a shared responsibility across the Scrum Team .
* The Product Owner must ensure that the product delivers value to stakeholders , which includes meeting their quality expectations.
* Ignoring the Product Owner's concerns contradicts Scrum's emphasis on collaboration and transparency.
質問 # 57
You are the Scrum Master of a new, to be developed product. Development is going to require 45 people. What is a good first question for you to suggest the group thinks about when forming into teams?
- A. What is the right mixture of senior and junior people on each team?
- B. How will we make sure all teams have the right amount or expertise?
- C. Who are going to be the team leads?
- D. Who are the subject matter experts on each team?
正解：B
解説：
The correct answer is A, because a good first question for you to suggest the group thinks about when forming into teams is how will we make sure all teams have the right amount of expertise.
This question helps the group consider the cross-functionality and self-organization of the Development Teams, which are essential for delivering a potentially releasable Increment every Sprint.
質問 # 58
Who is responsible for collaboration with stakeholders?
(choose the best answer)

- A. The Stakeholders.
- B. The Developers.
- C. The Scrum Master.
- D. The Product Owner.
- E. The Scrum Team.
正解：D
解説：
According to the Scrum Guide, the Product Owner has the final decision about the order of items in the Product Backlog, as he or she is responsible for maximizing the value of the product and the work of the Development Team. The other roles do not have this authority, although they may provide input and suggestions to the Product Owner.
質問 # 60
What is the best suited structure for Development Teams in order to produce integrated Increments?
- A. Each Development Team develops functionality from beginning to end throughout all technical layers.
- B. Each Development Team works only one technical layer of the system (e.g. GUI, database, middle tier, interfaces).
正解：A
質問 # 61
The Development Team should have all the skills needed to:
- A. Turn Product Backlog items into an Increment of potentially releasable product functionality.
- B. Do all of the development work, except for specialized testing that requires additional tools and environments.
- C. Complete the project within the date and cost as calculated by the Product Owner.
正解：A
解説：
According to the Scrum Guide, an Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together. In order to provide value, an Increment must be usable. Multiple Increments may be created within a Sprint. The sum of the Increments is presented at the Sprint Review thus supporting empiricism. However, an Increment may be delivered to stakeholders prior to the end of the Sprint. The Sprint Review should never be considered a gate to releasing value. Therefore, in order to turn Product Backlog items into an Increment of potentially releasable product functionality, the Development Team should have all the skills needed.
