True or False: Scrum is a methodology that tells in detail how to build software incrementally.
Answer : B
The Scrum Guide defines Scrum as 'a lightweight framework that helps people, teams, and organizations generate value through adaptive solutions for complex problems.' It provides roles, events, and artifacts but intentionally avoids prescribing detailed 'how-to' processes for building software (e.g., coding practices, tools). This distinguishes it from a methodology, which offers specific steps. Scrum focuses on 'what' (e.g., deliver an Increment) and leaves 'how' to the team's discretion, making the statement false. Thus, B is correct.
Question 2
How much work must the Developers do to a Product Backlog item it selects for a Sprint? (Choose the best answer)
Answer : A
The Scrum Guide mandates that all work selected for a Sprint must meet the Definition of 'Done': 'The Increment is the sum of all the Product Backlog items completed during a Sprint and the value of the increments of all previous Sprints.' During Sprint Planning, the Developers forecast what they can deliver as a 'Done' Increment, committing to that scope. Option A reflects this accountability. Option B suggests incomplete work carries over, which violates the Increment's usability requirement. Option C is too vague and not tied to 'Done.' Option D imposes a process Scrum doesn't require. Thus, A is correct.
Question 3
What is the Product Owner accountable for in Scrum? (Choose the best answer)
Answer : B
The Product Owner's core accountability is maximizing value through the Product Backlog. The Scrum Guide states: 'The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team.' Option B encapsulates this fully.
A: The Developers deliver the Increment; the Product Owner doesn't ensure it.
C: Refinement is part of management, but not the sole accountability.
D: Writing User Stories is a technique, not the overarching duty.
Exact Extract from Scrum Guide: 'The Product Owner is accountable for effective Product Backlog management, which includes: Developing and explicitly communicating the Product Goal; Creating and clearly communicating Product Backlog items; Ordering Product Backlog items; and, Ensuring that the Product Backlog is transparent, visible and understood.' (Section: 'The Product Owner')
Thus, B is correct.
Question 4
When a Developers determines that it has over-committed itself for a Sprint, who has to be present when reviewing and adjusting the Sprint work selected? (Choose the best answer)
Answer : B
The Scrum Guide states that the Sprint Backlog is owned by the Developers, who are responsible for planning and executing the work to achieve the Sprint Goal. If they realize they've over-committed, they must adjust the Sprint Backlog. However, since the Product Owner is accountable for maximizing value and managing the Product Backlog, their involvement is critical to ensure adjustments align with value delivery and the Sprint Goal. The Scrum Guide notes: 'The Product Owner may influence the Developers by helping them understand and select trade-offs.' Option A includes a non-existent 'project manager' role in Scrum, making it incorrect. Option C involves stakeholders, who are not part of mid-Sprint adjustments (they provide feedback at the Sprint Review). Option D excludes the Product Owner, which is insufficient given their role. Thus, B is correct.
Question 5
Why is it imperative that the Scrum Master attend the Daily Scrum?
Answer : D
The Daily Scrum is the Developers' event, not the Scrum Master's. The Scrum Guide states: 'The Daily Scrum is a 15-minute event for the Developers of the Scrum Team... The Scrum Master ensures that the Developers have the meeting, but the Developers are responsible for conducting the Daily Scrum.' The Scrum Master's role is to ensure it happens and is effective, not to attend mandatorily.
A: Documenting impediments is a support task, not a Daily Scrum requirement.
B: Facilitation is optional, only if requested.
C: Burndown charts aren't mandated; this isn't their purpose.
D: Correct---they ensure it occurs, not that they must be present.
Exact Extract from Scrum Guide: 'The Scrum Master ensures that the Developers have the meeting, but the Developers are responsible for conducting the Daily Scrum. The Scrum Master teaches the Developers to keep it within the 15-minute timebox.' (Section: 'Daily Scrum')
Thus, D is correct.
Question 6
The Sprint Goal is a result of Sprint Planning, as is the Sprint Backlog. True or False?
Answer : A
The Sprint Goal and the Sprint Backlog are both outcomes of Sprint Planning, making this statement true. According to the Scrum Guide, Sprint Planning is an event where the Scrum Team collaborates to define the work to be performed during the Sprint. The Sprint Goal is a single objective set for the Sprint, providing focus and coherence to the work selected. It is crafted collaboratively by the Product Owner, Developers, and Scrum Master during Sprint Planning. Simultaneously, the Sprint Backlog is created, consisting of the Product Backlog items selected for the Sprint plus a plan to deliver them, aligned with the Sprint Goal. The Scrum Guide states: 'Sprint Planning initiates the Sprint by laying out the work to be performed... This resulting plan is created by the collaborative work of the entire Scrum Team.' Thus, both the Sprint Goal and Sprint Backlog emerge from this event, confirming option A as correct.
Question 7
Which of the following best describes an Increment of working software? (Choose the best answer)
Answer : E
The Scrum Guide defines an Increment as 'a concrete stepping stone toward the Product Goal' that is usable and meets the Definition of 'Done': 'Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together.' Option E captures this---new, usable features that build on previous work. Option A (test suite) is a tool, not an Increment. Option B (UML diagrams) is documentation, not working software. Option C (task decomposition) is planning, not a product. Option D (UI design) isn't necessarily usable software. Thus, E best describes an Increment.
