- E. It provides a good overall direction so Sprints will feel less like isolated pieces of work.
正解：A、B、E
解説：
Explanation
The advantages of a Product Owner sharing a clearly defined Product Goal with the Scrum Team are:
* It provides a good overall direction so Sprints will feel less like isolated pieces of work. The Product Goal is a long-term objective for the product that guides all the activities of the Scrum Team. It helps the Scrum Team align their efforts and focus on delivering value that contributes to the product vision.
* It helps the Scrum Team keep focus and they can weigh any decision against the Product Goal. The Product Goal serves as a filter for deciding what to work on and what not to work on. It helps the Scrum Team prioritize and optimize their work based on value and impact.
* It is easier to inspect incremental progress at the Sprint Review. The Sprint Review is an event where the Scrum Team and the stakeholders collaborate on the product and inspect how it meets the Product Goal. The Increment is a concrete and usable outcome of the Sprint that provides a measure of progress towards the Product Goal.
Other options, such as helping the Developers estimate the date that the Product Backlog will be complete or being not mandatory in Scrum, are not valid advantages of having a Product Goal. They may reflect a misunderstanding of what a Product Goal is or how Scrum works.

質問 # 285
A Scrum Team has been working on a product for 9 Sprints. A new Product Owner who is new to Scrum joins the team and understands she is accountable for the Product Backlog. However, she is unsure about the purpose of the Product Backlog. She has read that the Product Backlog should be a list of all user features for the product. She goes to the Scrum Master asking where to put the other types of requirements that are going to be taken into account. Are all of the following types of requirements acceptable on a Product Backlog?
* Stability requirements
* Performance requirements
* Product Functionality
* Documentation
* Fixes
(choose the best answer)
- A. Yes, they all belong on the Product Backlog. The Product Backlog is supposed to be the "single source of truth" for all the work for the product.
- B. No. Product Backlog is a tool for the Product Owner. The Product Owner represents the users and stakeholders. Other types of requirements should be managed separately by the Developers. They are not the Product Owner's concern.
正解：A
解説：
Explanation
* The Product Backlog is an ordered list of everything that is known to be needed in the product. It is the single source of truth for the Scrum Team and the stakeholders. It contains all the requirements, features, functions, enhancements, fixes, and anything else that can deliver value to the customers and users of the product.
* All types of requirements are acceptable on a Product Backlog, as long as they are aligned with the product vision and goals, and they are transparent, clear, and valuable. The Product Backlog can include stability requirements, performance requirements, product functionality, documentation, fixes, or any other aspects that contribute to the quality and usability of the product.
* The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. The Product Owner is responsible for managing and refining the Product Backlog, collaborating with the stakeholders and the Developers, and ordering the items in a way that best achieves goals and missions. The Product Owner represents the interests of everyone with a stake in the product and ensures that the Scrum Team works on the right things at the right time.
* The Developers are accountable for creating a "Done" Increment that meets the Definition of Done each Sprint. The Developers are responsible for planning and executing the Sprint Backlog, designing and building the product functionality, testing and improving the product quality, and delivering a potentially releasable Increment. The Developers work closely with the Product Owner to understand and clarify the Product Backlog items, provide feedback and estimates, and suggest improvements and innovations.

正解：B
質問 # 290
What is the timebox for the Sprint Review?
(choose the best answer)
- A. 4 hours for a one-month Sprint.
- B. 1 day.
- C. As long as needed.
- D. 2 hours for a one-month Sprint.
正解：A
解説：
Explanation
The timebox for the Sprint Review is four hours for a one-month Sprint. This is because:
* The Sprint Review is an event where the Scrum Team and stakeholders inspect the Increment and adapt the Product Backlog if needed. The purpose of the Sprint Review is to elicit feedback and foster collaboration.
* The timebox for each Scrum event is proportional to its frequency and duration. A one-month Sprint corresponds to a maximum calendar month.
* The timebox for a one-month Sprint Review is four hours. For shorter Sprints, it is usually shorter.
* The timebox ensures that there is enough time to inspect what has been done in relation to what could be done next and make any necessary adaptations to optimize value.
Other options, such as two hours for a one-month Sprint, one day, or as long as needed, are not valid answers as they do not reflect the correct timebox for the Sprint Review.
