Learning turns into 'validated learning' when assumptions and goals can be assessed through results. What is a key way for a Product Owner to apply validated learning?
정답:
A key way aProduct Owner applies validated learningis byadapting the Product Backlog and Product Goal based on evidence from real outcomes, not assumptions.
Through inspection of:
* TheProduct Incrementduring the Sprint Review,
* Stakeholder and user feedback,
* Measured outcomes such as usage, value, or risk reduction,
the Product Owner assesses whether assumptions about value, users, or direction are valid. This learning becomesvalidatedonly when it is reflected inchanged decisions, such as:
* Reordering Product Backlog items,
* Adding or removing backlog items,
* Adjusting or even abandoning a Product Goal.
In other words, validated learning is applied when the Product Owneruses results to change what is built next, ensuring that future work is based on evidence rather than speculation.

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?
정답:
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.

The definition of "Done" describes the work that must be completed for every Product Backlog item before it can be deemed releasable. What should the Development Team do when, during the Sprint, it finds out that a problem outside of their control blocks them from doing all this work?
정답:
When the Development Team discovers during a Sprint that a problemoutside of their controlprevents them from completing all work required by theDefinition of Done, this situation must be addressed through transparency, inspection, and adaptation, rather than by lowering standards.
1. Make the Impediment Transparent Immediately
The Development Team shouldmake the issue visible as soon as it is discovered. This includes:
* Raising it in theDaily Scrum,
* Clearly stating how it impacts the Sprint Goal and the Definition of Done.
Transparency is critical so that inspection and adaptation are based on reality, not assumptions.
2. Do Not Compromise the Definition of Done
The Definition of Done mustnot be relaxed or bypassedto "get something done." Lowering quality destroys transparency and creates false progress. If the Definition of Done cannot be met, the work isnot Doneand should not be considered releasable.
3. Collaborate to Adapt the Sprint Backlog
The Development Team should collaborate with theProduct Ownerto inspect the impact and adapt the Sprint Backlog. This may include:
* Removing or adjusting affected Product Backlog Items,
* Focusing on work that can still meet the Definition of Done,
* Preserving theSprint Goal, if possible.
4. Escalate the Impediment Through the Scrum Master
Because the problem is outside the team's control, it qualifies as animpediment. The Scrum Master must help remove or mitigate it by working with the organization or external parties. If the impediment cannot be resolved quickly, its impact should be addressed in planning and stakeholder communication.

What artifacts are part of Scrum, and during which Scrum Events are they likely to be the subject of inspection?
정답:
Scrum defines three coreartifactsthat provide transparency into the work being done and the value being delivered: theProduct Backlog, theSprint Backlog, and theProduct Increment. Each artifact is inspected at specific Scrum Events to support empiricism throughtransparency, inspection, and adaptation.
Product Backlog
TheProduct Backlogis an ordered list of everything that is known to be needed in the product and is the single source of work for the Scrum Team.
* It isinspected during Sprint Planning, where the Scrum Team selects Product Backlog Items to work on and aligns them with the Sprint Goal.
* It is alsoinspected during the Sprint Review, where stakeholders and the Scrum Team review progress and adapt the Product Backlog based on feedback and new insights.
* In addition, the Product Backlog is continuously inspected and adapted duringBacklog Management (often called refinement). While this activity is essential, it isnot a Scrum event in the strict sense.
Sprint Backlog
TheSprint Backlogconsists of the Sprint Goal, the selected Product Backlog Items for the Sprint, and a plan for delivering them.
* It iscreated and inspected during Sprint Planning, where the Developers forecast the work needed to achieve the Sprint Goal.
* It isinspected daily during the Daily Scrum, as Developers assess progress toward the Sprint Goal and adapt their plan accordingly.
* It may also beinspected during the Sprint Reviewto provide transparency into what was planned versus what was accomplished.
Product Increment
TheProduct Incrementis the sum of all completed Product Backlog Items during the Sprint and previous Sprints that meet the Definition of Done.
* It isinspected during Sprint Planning, to understand the current state of the product and determine what can be built next.
* It isinspected during the Sprint Review, where stakeholders evaluate the Increment and provide feedback.
* The Increment may also be inspected at any time to support transparency and decision-making.
Continuous Inspection Beyond Events
While Scrum defines specific events where artifacts are commonly inspected, the Scrum Guide emphasizes thatartifacts may be inspected at any time, as long as the inspection does not hinder progress. Scrum encouragesfrequent inspectionto enable timely adaptation and reduce risk.
