During a Sprint, when is new work or further decomposition of work added to the Sprint Backlog?
Answer(s): B
The correct answer is B, because the Scrum Guide states that "the Development Team modifies theSprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint. This emergence occurs as the Development Team works through the plan and learns more about the work needed to achieve the Sprint Goal." Therefore, new work or further decomposition of work can be added to the Sprint Backlog as soon as possible after they are identified by the Development Team.
What it the main reason for the Scrum Master to be at the Daily Scrum?
Answer(s): C
The correct answer is C, because the Scrum Guide states that "the Scrum Master ensures that the Development Team has the meeting, but the Development Team is responsible for conducting the Daily Scrum. The Scrum Master teaches the Development Team to keep the Daily Scrum within the 15-minute time-box." Therefore, the main reason for the Scrum Master to be at the Daily Scrum is to ensure that it happens, but he or she does not have to be there.
You have six teams using a traditional method to deliver a product. Your management has asked you to start using Scrum. In the initial project there were separate plans and teams for the layers of a software system, i.e. one for the front-end, one for the middle tier, one for the back-end, and one for the interfaces and services. This resembles what is known as component teams. But you have read that it's a good idea to have teams organized by feature.What are the advantages of keeping component teams while starting Scrum?
Answer(s): A
The correct answer is A, because keeping component teams while starting Scrum may cause less initial disruption than organizing into new teams. As they start using Scrum, they will discover what works best for them and how to potentially re-organize towards feature teams. However, component teams may face some challenges in delivering a working Increment of software that provides business value every Sprint, as they may depend on other teams or layers.
How should Product Backlog items be chosen when multiple Scrum Teams work from the same Product Backlog?
The correct answer is B, because when multiple Scrum Teams work from the same Product Backlog, they should pull in work in agreement with the Product Owner. The Scrum Guide states that "multiple Scrum Teams often work together on the same product. One product goal unites them. Therefore, they must mutually define and comply with a definition of `Done' that applies to their combined work product." Therefore, they should collaborate and coordinate with each other and with the Product Owner to select Product Backlog items that align with their shared product goal.
How often should Scrum Team membership change?
The correct answer is A, because Development Team membership should change as needed, while taking into account a short term reduction in productivity. The Scrum Guide states that "development Teams are cross-functional, with all of the skills as a team necessary to create a product Increment; development Teams are self-organizing. No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality." Therefore, changing Development Team membership may affect their cross- functionality and self-organization in the short term.
