Roles in Scrum vs Other Agile Frameworks

Correct Answer: In Scrum, the product owner prioritizes the backlog and is responsible for product value, while in Kanban, there's no set 'product owner' role and decisions can be made by anyone authorized.

The main difference between the two methodologies is that Scrum introduces the role of the product owner, who is responsible for prioritizing the product backlog and ensuring that the team is focused on delivering maximum business value. This is in contrast to Kanban, which does not stipulate any specific role for the product owner. Here, decisions can be made by anyone in the team who is authorized to do so. The other answers incorrectly state that there is no Product Owner role in Scrum (which is false), or that the role of Product Owner is the same in both Scrum and Kanban methodologies (also false), or that the product owner in Kanban is solely responsible for decision making (incorrect, as Kanban does not specify a product owner role).

Correct Answer: While both roles focus on facilitation and helping the team work better, Coaches in XP also often take part in programming tasks unlike Scrum Masters.

The most accurate comparison between a Scrum Master in Scrum and a Coach in Extreme Programming (XP) is the first answer. Both roles indeed focus on facilitation and helping their teams cooperate more effectively. However, unlike Scrum Masters, Coaches in XP often partake in actual programming tasks. The second answer is incorrect as the roles of a Scrum Master and a Coach may share similarities, but they are not the same. The third answer is incorrect because XP does indeed have a Coach role. The last answer is also incorrect because it oversimplifies and inaccurately represents the skills required for both roles. Coaches in XP do need to have programming skills, but they also need additional skills related to team facilitation and coaching. In contrast, a Scrum Master also needs a variety of skills including team facilitation, knowledge of Scrum, problem solving, and more, not 'no skills' as it is mentioned in the answer.

Correct Answer: The Product Owner, who manages the Product Backlog and ensures the product vision is understood

In Scrum, the Product Owner is responsible for maximizing the value of the product and the work of the Development Team. The Product Owner does this by managing the Product Backlog, ensuring that it is visible, transparent, and clear to all, and shows what the Scrum Team will work on next. The Scrum Master, on the other hand, serves the Scrum Team by facilitating Scrum events and helping to remove impediments, but is not directly responsible for maximizing product value. The Development Team is responsible for delivering potentially releasable Increments each Sprint, but the overall product value is the Product Owner's responsibility. A Project Manager role is not defined in Scrum, as Scrum Teams are self-organizing and cross-functional.
