Which one of the following statements about the history of Scrum is NOT correct?

A.The idea of Scrum was derived from a “rugby” approach, in which “a team tries to go the distance as a unit, passing the ball back and forth.”
B.Takeuchi and Nonaka proposed that product development should be like a sequential relay race.
C.Scrum was based on a flexible and all-inclusive product development strategy where the development team works as a unit to reach a common goal.
D.Takeuchi and Nonaka based their approach on manufacturing case studies from various industries.

정답:
Explanation:
Takeuchi and Nonaka proposed that product development should not be like a sequential relay race, but
rather should be analogous to the game of rugby where the team works together, passing the ball back and forth as they move as a unit down the field. The rugby concept of a “Scrum” (where a group of players form together to restart the game) was introduced in this article to describe the authors’ proposal that product development should involve “moving the Scrum downfield”.

Question No : 4

Who among the following can directly approve changes recommended in the project?

A.Product Owner
B.Scrum Guidance Body
C.Scrum Master
D.Senior Management

정답:
Explanation:
The Scrum Guidance Body usually defines a process for approving and managing changes throughout the organization. In the absence of a formal process, it is recommended that small changes that do not have a significant impact on the project be directly approved by the Product Owner. The tolerance for such small changes could be defined at an organizational level or by the sponsor for a particular project. In most projects, 90% of Change Requests could be classified as small changes that should be approved by the Product Owner. So, the Product Owner plays a very important role in managing changes in a Scrum Project.

Question No : 7

Which of the following is true about a Prioritized Product Backlog?

A.A Prioritized Product Backlog should not have the most valuable User Story on top, because it could be risky.
B.Greater value items, although potentially riskier, are given higher priority in a Prioritized Product Backlog.
C.Uncertainty should be ruled out of the Risk-adjusted Prioritized Product Backlog.
D.For a Sprint to succeed, User Stories picked for a Sprint should be interlinked with those selected for subsequent Sprints.

정답:
Explanation:
The more uncertainty exists in a project, the riskier the project is. Therefore, it is important that riskier products in the Prioritized Product Backlog are given higher priority. Products carrying a higher level of risk will also require risk mitigation actions. When these risk mitigation actions are prioritized against the backlog, the result is a Risk Adjusted Product Backlog. Dealing with risks early in the project does not guarantee that the project will be successful, but it does enhance the team’s ability to deal with risk.

Question No : 11

Each Scrum role has specific responsibilities in managing a Scrum project. Below, choose the role that is correctly matched to its responsibility.

A.Product Owner - invites to a grooming session only those stakeholders whose feedback is required and who can make final decisions about which suggested changes can be considered as Formal Change Requests.
B.Scrum Master - ensures that the requirements and Acceptance Criteria are not altered during the Sprint Review Meeting.
C.Stakeholders - incorporate new and modified features into the deliverables whenever possible.
D.Scrum Team - decide whether the change can wait until the next Sprint or represents an urgent situation that may require ending the current Sprint and starting a new one.

정답:
Explanation:
Although the Stakeholder(s) and the Product Owner have the final say on Prioritized Product Backlog Items and whether to accept or reject any Change Requests presented during Demonstrate and Validate Sprint, it is the Scrum Master’s responsibility to ensure that the requirements and Acceptance Criteria are not altered during the Sprint Review Meeting for the User Stories completed in the current Sprint. This prevents the rejection of completed User Stories based on the fact that they do not meet newly changed requirements. If any requirements need to be changed, any corresponding PBI needs to be revised to accommodate the modified requirements in a future Sprint.

Question No : 12

A Scrum Team is estimating the prioritized User Stories. Each team member has been assigned a deck of numbered cards, in which each card is numbered in a sequence. The team members use these cards to assess a particular User Story by picking and showing a card from the deck that represents their estimate for the User Story.
Which estimation tool is the Scrum Team using?

A.Fist of Five.
B.Wideband Delphi.
C.Affinity Estimation.
D.Planning Poker.

정답:
Explanation:
Planning Poker is an agile estimating and planning technique that is consensus based. To start a poker planning session, the product owner or customer reads an agile user story or describes a feature to the estimators.
Each estimator is holding a deck of Planning Poker cards with values like 0, 1, 2, 3, 5, 8, 13, 20, 40 and 100, which is the sequence we recommend. The values represent the number of story points, ideal days, or other units in which the team estimates.
