最新的Scrum Professional Scrum Master level III (PSM III) - PSM-III免費考試真題
問題1
Someone from the HR department approaches you. They regret to inform you that the Product Owner for your team isabsent starting today and will be unavailable for the rest of this sprint. The Product Owner might be back at work somewhereduring the next sprint, but it's all unknown at this point. What should the Scrum team do?
正確答案:
When the Product Owner becomes unexpectedly unavailable, the Scrum Team must respond in a way that preservescontinuity, transparency, and value delivery, while respecting Scrum accountabilities.
Short-Term Response
In theshort term, covering the current Sprint and possibly the next Sprint, the Scrum Team should be able to continueworking. Scrum is designed to be resilient to short-term disruptions. The team can proceed by relying on:
* TheProduct Visionpreviously communicated by the Product Owner,
* Thecurrent state and ordering of the Product Backlog, which should already reflect the Product Owner's value decisions.
During this period, the Developers continue to work toward the Sprint Goal, and the Scrum Master ensures that Scrum events take place and remain productive. No one should assume the Product Owner role informally, as this would undermine accountability.
Longer-Term Impact
If the Product Owner's absence extends beyond a short period, it becomes animpedimentto the Scrum Team.
The Product Owner is accountable for maximizing product value and managing the Product Backlog.
Prolonged absence prevents effective backlog ordering, stakeholder collaboration, and value-based decision- making.
In this case, theScrum Master must make the impediment visible to the organization. This includes explaining the impact on value delivery and helping leadership understand the need for a clear Product Owner accountability. The organization should thenappoint a new Product Ownerto ensure continuity of decision- making and accountability.

問題2
How the organization discusses and plans the work of creating software will be reflected in the implementation of that software.
Technical systems can be decomposed to composite elements, from the large to the small. Basic components may be represented as activities, workflows, functions, features, capabilities, and other similar nomenclature.
How does this system decomposition affect Scrum Teams on scaled projects?
Technical systems can be decomposed to composite elements, from the large to the small. Basic components may be represented as activities, workflows, functions, features, capabilities, and other similar nomenclature.
How does this system decomposition affect Scrum Teams on scaled projects?
正確答案:
How an organization discusses, plans, and decomposes work is inevitably reflected in the software it produces. When technical systems are decomposed into elements such as activities, workflows, functions, features, or components, these decomposition choices have adirect and systemic impact on Scrum Teams, especially inscaled Scrum environments.
1. Decomposition Influences Team Structure (Conway's Law)
In scaled projects, system decomposition often drives how teams are formed. When work is decomposed along technical components or functions, organizations tend to createspecialist or component teams(e.g., front- end teams, back-end teams). This results in:
* Increaseddependencies between teams,
* More handoffs and coordination,
* Reduced autonomy of individual teams.
Scrum, however, expects teams to becross-functionaland capable of delivering usable Increments independently. Component-based decomposition therefore hinders effective Scrum adoption at scale.
2. Effect on Value Delivery and Transparency
Scrum relies on frequent inspection ofintegrated, working product Increments. When decomposition focuses on small technical parts rather thanend-to-end features or capabilities, teams may deliver partial outputs instead of usable value.
This negatively affects:
* Transparency, as progress is reported through intermediate artifacts rather than working software,
* Inspection, since stakeholders cannot meaningfully evaluate value,
* Adaptation, because feedback is delayed until integration occurs.
In scaled Scrum, this often results in "almost done" work that is not truly Done.
3. Feature-Oriented Decomposition Supports Scrum
Scrum scales more effectively when system decomposition emphasizesvertical slices of value, such as features or capabilities, rather than horizontal technical layers. Feature-oriented decomposition enables:
* Cross-functional teams,
* Reduced dependencies,
* Faster feedback cycles,
* Independent delivery of value by each team.
This approach aligns with Scrum's expectation that every Sprint produces ausable Increment.
4. Impact on Integration and Risk
Decomposition decisions strongly affectintegration frequency. Poor decomposition increases integration complexity and encourages late integration, which raises risk and reduces learning.
In Scrum-especially at scale-integration must happen early and often. Unintegrated work is not considered Done, and delayed integration undermines empiricism by hiding real system behavior until late in development.
5. Learning and System Optimization
When Scrum Teams work on complete features rather than isolated components, they gain broader insight into:
* Customer needs,
* System-wide trade-offs,
* End-to-end product behavior.
This shared understanding improves decision-making and supportscontinuous improvement at the system level, rather than local optimization within silos.

問題3
In what way does Scrum encourage ethical behaviour, doing "the right thing", in software development?
正確答案:
Scrum encourages ethical behaviour in software development by creating a framework that promotes transparency, accountability, quality, and respect for stakeholders, all of which are grounded in the Scrum Values. Rather than prescribing ethical rules, Scrum embeds ethical behaviour into the way work is organized and delivered.
First, Scrum promotes ethics through its focus ondelivering valuable, high-quality working products. The Scrum Guide emphasizes delivering usable Increments that meet a shared Definition of Done. By prioritizing quality and value for both the organization and end-users, Scrum discourages practices such as cutting corners, hiding technical debt, or delivering misleading progress, which are ethically questionable.
Second, Scrum strongly supportstransparency, a core pillar of empiricism. All significant aspects of the work-such as progress, impediments, risks, and uncertainties-are made visible through artifacts and events.
This transparency encourages honesty about what can and cannot be achieved and prevents unethical behaviour such as misreporting status or concealing problems until it is too late.
Third, Scrum encouragesaccountabilityat both individual and team levels. Clear accountabilities for the Product Owner, Developers, and Scrum Master ensure that responsibility is not diffused or avoided. Teams are accountable for delivering value, improving their way of working, and meeting their commitments. This accountability fosters ethical decision-making and ownership of outcomes.
Fourth, Scrum supports ethical behaviour throughcontinuous learning and improvement. Sprint Retrospectives create a structured opportunity to reflect on mistakes, share knowledge, and improve processes and practices. This openness to learning promotes humility, integrity, and a willingness to correct issues rather than ignoring or rationalizing them.
Finally, Scrum is explicitly guided by theScrum Values of Commitment, Courage, Focus, Respect, and Openness, which form its ethical foundation.
* Commitmentencourages teams to do what they say they will do.
* Courageenables individuals to raise concerns, admit problems, and challenge unethical practices.
* Focushelps teams concentrate on delivering real value rather than superficial outputs.
* Respectensures consideration for colleagues, stakeholders, and end-users.
* Opennesspromotes honesty about progress, challenges, and uncertainty.

When working on one software product with multiple Scrum teams in Scrum Nexus, what is important about dependenciesof the planned Backlog Items and integration of the work being done?
正確答案:
When multiple Scrum Teams work together on a single product usingScrum Nexus, managing dependencies and ensuring effective integration are critical to delivering a usable Increment each Sprint. Scrum Nexus extends Scrum by explicitly addressing the complexity that arises from multiple teams working on the same product.
First,dependencies between teams should be minimized. Dependencies reduce autonomy, slow feedback, and increase risk. In Nexus, Product Backlog Items should be ordered and refined in such a way that work with strong dependencies is keptwithin a single team whenever possible. This supports cross-functionality at the team level and reduces the coordination overhead required between teams.
Second, when dependencies cannot be avoided, they must be madetransparent and actively managed. The Nexus framework encourages early identification of dependencies during Nexus Sprint Planning so that teams can coordinate their work effectively. However, the goal remains to continuously reduce dependencies over time through better backlog ordering, architecture improvements, and skill broadening.
Third,integration of work is vital and takes precedence over completing all planned work. In Scrum Nexus, an Increment is only considered "Done" when the work of all teams is fully integrated and meets the shared Definition of Done. Unintegrated work, even if technically complete by an individual team, does not provide value and increases risk.
Fourth, integration must occurearly and often during the Sprint, not only at the end. Continuous integration helps uncover issues sooner, supports frequent inspection, and enables timely adaptation. Delaying integration increases the likelihood of defects, rework, and failure to produce a usable Increment.
