Scrum PSPO-I Exam Preparation Materials

Correct Answer: ABC

Explanation: The Product Owner orders the Product Backlog items according to various criteria, such as:

The value of Product Backlog items. The Product Owner aims to maximize the value of the product and the work of the Scrum Team. Therefore, they prioritize the items that deliver the most value to the stakeholders and the users,

considering factors such as customer satisfaction, market share, revenue, social impact, etc. The dependencies between Product Backlog items. The Product Owner tries to minimize the dependencies between items, as they may create

complexity, uncertainty, and risk. Therefore, they order the items in a way that reduces or eliminates the dependencies, or resolves them as early as possible. The dependencies to other products. The Product Owner also considers the

dependencies that the product has to other products, such as platforms, frameworks, libraries, services, etc. Therefore, they order the items in a way that aligns with the availability and compatibility of those products.

Correct Answer: AE

The ideal time for refinement to take place and who should participate are the Scrum Team during the current Sprint, if they have been unable during preceding Sprints to define Product Backlog items with enough precision to begin work, and

the Scrum Team on an ongoing basis, defining Product Backlog items into smaller more precise items that are ready for selection. This is because:

Product Backlog refinement is the act of adding detail, estimates, and order to Product Backlog items. It is an ongoing and collaborative process that involves the whole Scrum Team.

The Scrum Team should refine the Product Backlog as needed to ensure that there are enough items that are sufficiently clear and ready for selection in Sprint Planning. The amount of time spent on refinement usually varies from one Scrum

Team to another, but it is recommended not to exceed 10% of the capacity of the Developers.

The Scrum Team may also use a Sprint to refine the Product Backlog if they have not been able to do so in previous Sprints. This may happen when the product is new or complex, or when there is a significant change in the product vision or

direction. However, this should be an exception rather than a rule, as it may delay the delivery of value and feedback.

Other options, such as business analysts doing the refinement work for the Scrum Team, the Product Owner doing the refinement alone in Sprint 0 or between Sprints, or handing off the ownership of the Product Backlog to someone else, are

not consistent with the principles and values of Scrum. They may lead to misunderstandings, misalignment, or loss of ownership and accountability.

Correct Answer: C

Sprints are fixed-length events of one month or less that serve as a container for the other Scrum events and activities. Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint. There is no gap or downtime between Sprints. The second Sprint starts right after the first Sprint, regardless of the customer acceptance testing, the architectural changes, or the Product Backlog items.
