Your Scrum Team has one month Sprints. The development team argues that since this period is quite long, a Daily Scrum isa bit too much. They instead want a weekly update meeting. What is your opinion on this?
정답:
From a Scrum Master's perspective, replacing the Daily Scrum with a weekly update meeting isnot consistent with Scrumand would significantly weaken the team's ability to inspect and adapt effectively, regardless of the Sprint length.
First, Scrum explicitly defines theDaily Scrum as a required event. The Scrum Guide states that the Daily Scrum is a 15-minute event held every working day of the Sprint for the Developers. The length of the Sprint-whether one week or one month-does not change the purpose or necessity of this event. Therefore, by choosing not to have a Daily Scrum, the team wouldno longer be practicing Scrum, but rather a Scrum- like process.
Second, the Daily Scrum isnot a status meeting. Its primary purpose is to allow the Developers toinspect progress toward the Sprint Goal, synchronize their work, andadapt the Sprint Backlogas needed. A weekly meeting dramatically reduces the frequency of inspection and adaptation, delaying the discovery of issues such as integration problems, misalignment, or risks to the Sprint Goal.
Third, removing the Daily Scrum negatively impactstransparency, one of Scrum's three pillars of empiricism. Without daily synchronization, important information about progress, impediments, and discoveries becomes stale or hidden. This reduced transparency increases the likelihood that work will drift away from agreed standards, fail to integrate properly, or no longer support the Sprint Goal by the end of the Sprint.
Fourth, the argument that a one-month Sprint justifies less frequent inspection reflects a misunderstanding of empiricism. Longer Sprintsincrease risk, which makes frequent inspection and adaptation more important, not less. The Daily Scrum provides a regular opportunity to realign the team and respond early to emerging problems, thereby reducing waste and rework.
Finally, as a Scrum Master, my role is toteach and coachthe Scrum Team on the purpose and value of Scrum events. Rather than removing the Daily Scrum, I would help the Developers improve how they use it-for example, ensuring it focuses on progress toward the Sprint Goal and actionable planning for the next 24 hours, instead of turning into a reporting session.

Describe the difference between feature and component teams, and how they hold up when viewed from the perspective ofthe Scrum Guide.
정답:
In Scrum, team structure significantly impacts the ability to deliver value. Two commonly discussed structures arecomponent teamsandfeature teams. Although the Scrum Guide does not explicitly define these terms, it strongly favors the characteristics of feature teams through its definition of a Scrum Team.
Component teamsare organized around technical specialties or system components, such as database, frontend, or middleware teams. Their work typically represents partial contributions to a product feature, requiring coordination and handoffs across multiple teams to deliver customer value. As a result, component teams often introduce dependencies, delay integration, and struggle to produce a usable Increment independently within a Sprint.
Feature teams, in contrast, are organized around delivering complete product features or Product Backlog Items. They are cross-functional and possess all the skills required to design, build, test, and deliver a "Done" Increment of value. Feature teams minimize dependencies and can independently deliver customer-facing functionality each Sprint.
From theScrum Guide perspective, feature teams align more closely with Scrum principles:
* The Scrum Guide states thatScrum Teams are cross-functional, which directly supports feature teams and challenges component team structures.
* Scrum requires each Sprint to produce ausable Increment. Feature teams can meet this expectation, while component teams usually cannot without reliance on other teams.
* Scrum is based onempiricism(transparency, inspection, and adaptation). Reduced dependencies in feature teams improve transparency and enable faster inspection and adaptation.
* Scrum emphasizesvalue delivery and accountability. Feature teams maintain clear ownership of outcomes, whereas component teams fragment accountability across technical silos.
While component teams may exist due to legacy structures or technical constraints, they represent organizational impediments rather than an ideal Scrum implementation. From a Professional Scrum Master III perspective, moving toward feature teams supports agility, improves value delivery, and better enables Scrum as defined in the Scrum Guide.

The Product Owner asks the Development Team to pick up a very urgent item late in Sprint that was not forecasted, nor is itrelated to the Sprint Goal. The Development Team believes it can pick this up, as it is close to meeting the Sprint Goal. But, thiswould involve not meeting their process improvement goal agreed upon during the last Sprint Retrospective. The ProductOwner argues that, as it's the highest priority to satisfy the customer, the needs of the customer have a higher priority than theprocess improvement goal for the team.
What is your view on this as a Scrum Master?
What is your view on this as a Scrum Master?
정답:
From a Scrum Master's perspective, this situation must be approached by balancingrespect for Scrum accountabilities,protection of empiricism, andlong-term value delivery, rather than reacting solely to short- term urgency.
First, it is important to reaffirm that theDevelopment Team owns the Sprint Backlog. According to the Scrum Guide, once the Sprint has started, changes to the Sprint Backlog are negotiatedonly between the Product Owner and the Development Team, and the Development Team has thefinal sayon whether additional work can be taken on. Therefore, the Product Owner cannot unilaterally force the urgent item into the Sprint, even if it represents the highest customer priority. If the Development Team believes it can incorporate the item without jeopardizing the Sprint Goal, it may choose to do so-but this remains their decision.
Second, the Scrum Master should help the Product Owner understand thatnot all priorities are equal within a Sprint. The Sprint Goal provides focus and stability, and work that is not related to the Sprint Goal introduces risk. While satisfying the customer is important, Scrum explicitly valuessustainable improvement and learning. The process improvement goal agreed upon during the Sprint Retrospective represents a deliberate investment in the team's effectiveness. Sacrificing this improvement for short-term delivery may create a local optimization thatharms long-term customer value.
Third, the Scrum Master should coach both the Product Owner and the Development Team on thesystemic impact of slowing process improvements. Continuous improvement is a core expectation of Scrum, and the Scrum Guide states that the Scrum Team should plan ways to increase quality and effectiveness. When improvement goals are repeatedly deprioritized, delivery predictability, quality, and morale eventually decline-directly affecting customers. Therefore, the Product Owner's argument that customer needs always outweigh improvement work reflects ashort-term mindsetthat the Scrum Master should challenge through education and coaching.
Fourth, this situation should beinspected during the Sprint Retrospective. The team should reflect on why urgent, unplanned work appears late in the Sprint, whether it represents a recurringpattern, and how this impacts Sprint Goals and improvement commitments. The Scrum Master should facilitate this discussion to ensure transparency and learning, rather than blame.
Finally, if this behavior becomes a pattern, the Scrum Master must take a more active stance. This includes teaching and reminding the Scrum Team that at least one improvement from the Sprint Retrospective should be planned into the upcoming Sprint. This protects the intent of the Retrospective and ensures that improvement is not treated as optional or expendable work.

In what ways does the Scrum Master attend the Sprint Retrospective?
정답:
The Sprint Retrospective is a formal Scrum event where the Scrum Team inspects how the last Sprint went with respect toindividuals, interactions, processes, tools, and their Definition of Done, and identifies improvements for future Sprints. The Scrum Master attends the Sprint Retrospective inmultiple, complementary ways, consistent with the Scrum Guide.
First, the Scrum Masterjoins the Sprint Retrospective as a Scrum Team member. The Scrum Guide defines the Scrum Team as consisting of the Product Owner, Developers, and the Scrum Master. Therefore, the Scrum Master is not an external observer but afull participantin the event. As such, the Scrum Master activelyinspects people, processes, and tools, and contributes insights based on their perspective and experience, while remaining respectful of the team's self-management.
Second, the Scrum Master oftenfacilitates the Sprint Retrospective. According to the Scrum Guide, the Scrum Master is accountable for ensuring that Scrum events take place and are productive. Facilitation may include helping the team create a safe environment, encouraging openness, ensuring balanced participation, keeping the discussion focused on improvement, and helping the team stay within the timebox. However, facilitation does not imply control; the Scrum Master facilitatesto serve the team, not to direct outcomes.
Third, the Scrum Mastersupports empiricism during the Retrospective. By fostering transparency, encouraging honest inspection, and helping the team identify actionable improvements, the Scrum Master strengthens the Scrum pillars oftransparency, inspection, and adaptation. The Scrum Master may also help the team turn improvement ideas into concrete actions that can be planned for the next Sprint.
Finally, the Scrum Master helps ensure that the Sprint Retrospective results inmeaningful adaptation. While the Scrum Team decides what improvements to implement, the Scrum Master supports the team in identifying impediments, coaching on improvement techniques, and helping remove organizational or systemic obstacles that are beyond the team's direct control.
In summary, the Scrum Master attends the Sprint Retrospective byjoining as a full Scrum Team member, participating in inspection,often facilitating the event, andsupporting continuous improvement and empiricism. This balanced participation ensures that the Retrospective remains a powerful mechanism for learning and adaptation rather than a ritualistic meeting.
