The developers in your Scrum Team raise an impediment. The work planned for upcoming Sprint involves certain knowledge and expertise they do not possess within the team. How do you handle this impediment? 正解：
解説：
When Developers raise the lack of certain knowledge or expertise as an impediment, the Scrum Master must address the situation in a way that reinforcesScrum principles, especiallycross-functionality, empiricism, and self-management, while also supporting value delivery.
First, it is essential to verify whether this is truly animpediment. In Scrum, an impediment is something the team cannot resolve on its own. As a Scrum Master, I would facilitate a discussion with the Developers and, if appropriate, the Product Owner to inspect whether the expertise is genuinely required to achieve the desired outcome. In some cases, the scope or approach can be adapted, or the Product Backlog Item can be refined so that alternative solutions are viable. This conversation may reveal that the need for specialized knowledge is less critical than initially assumed.
Second, if the expertise is indeed necessary, the Scrum Master should encourage the team to address the issue as across-functional Scrum Team. Scrum expects teams to have, or acquire, all skills needed to deliver value. Therefore, I would ask the Developers how they couldlearn or acquire the necessary knowledge themselves. Possible options include allocating time for learning, research, training, experimenting, or building a prototype. These activities can be planned as part of the Sprint Backlog and support long-term team capability.
Third, the Scrum Master can help the team make effective use ofoutside expertise without undermining self- management. During Sprint Planning or refinement, the team may consult internal or external experts to gain insights, validate approaches, or reduce uncertainty, while still retaining ownership of the work and the Sprint Backlog.
Finally, if none of these options resolve the impediment, the Scrum Master has a responsibility tohelp the organization support the Scrum Team. This may involve facilitating access to expertise from elsewhere in the organization or, if necessary, from outside the organization. The Scrum Master does not solve the problem personally but works to remove organizational barriers so the team can proceed.

You have been appointed the Scrum Master for a brand new product your organization is planning to develop.
A ProductOwner has also been appointed. Initially, fifteen developers will work on the product. What approaches are common forforming teams for this product, and how do they likely benefit or hinder the Product Development effort? 正解：
解説：
When starting development of a brand new product with fifteen developers, forming effective teams is a critical early decision that significantly influences the success of product development. From a Scrum Master' s perspective, multiple approaches are commonly used in practice. Each approach offers distinct benefits and drawbacks when evaluated against Scrum principles such asself-organization, cross-functionality, and value delivery.
1. Facilitating Teams to Self-Organize
One common approach is tofacilitate the developers in forming teams themselves. This approach aligns strongly with Scrum, as the Scrum Guide states that Scrum Teams areself-managingand decide internally how best to accomplish their work.
Benefits:
Allowing teams to self-organize promotesempowerment, ownership, and accountability. Developers can use their existing knowledge of each other's strengths, weaknesses, and working styles to form balanced teams. This often increases motivation and psychological safety, both of which support high performance.
Hindrances:
For a new product, this process can bemessy and time-consuming, especially if developers lack experience in forming effective teams. Teams may optimize for comfort or familiarity rather than cross-functionality, potentially leading to skill gaps or imbalanced teams.
2. Forming Two or Three Cross-Functional Feature Teams
Another common approach is to deliberately formtwo or three cross-functional feature teams, each containing all the skills necessary to deliver working product increments.
Benefits:
This approach closely matches how Scrum describes teams.Cross-functional feature teamscan independently deliverintegrated, "Done" Incrementsof the product, improving flow, reducing dependencies, and supporting empiricism. All necessary skills are available within the team, enabling faster inspection and adaptation.
Hindrances:
In the context of a brand new product, teams may not yet knowwhich skills are actually required, making it difficult to form truly balanced teams upfront. Additionally, specialists may feel isolated and lose regular interaction with peers who share the same expertise across teams.
3. Forming Teams Based on Specialization (Component Teams)
A third approach is to organize teams according totechnical specialization, such as front-end and back-end teams. These are often referred to ascomponent teams.
Benefits:
This structure allows specialists to work closely together, enablingfast knowledge sharing, technical consistency, and deep expertisein specific components of the system. It can feel efficient, especially in the early stages of development.
Hindrances:
From a Scrum perspective, this approach significantly hindersvalue delivery. Component teams struggle to deliver complete, integrated features independently and introduce dependencies and handoffs. This makes it harder to produce a usable Increment each Sprint and isnot how Scrum describes teams, even though it remains a commonly used strategy in many organizations.
Scrum Master Perspective and Conclusion
As a Scrum Master, my role is not to mandate a single team structure, but tocoach and facilitatethe organization toward structures that best enable Scrum. While all three approaches are seen in practice, Scrum clearly favorsself-organizing, cross-functional feature teamsbecause they maximize learning, transparency, and the ability to deliver value each Sprint.

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? 正解：
解説：
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.

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? 正解：
解説：
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.

Mid-sprint a development team forecasts it will not be able to deliver all the planned backlog items. They are worried andask for your advice as Scrum Master. What will you tell them? 正解：
解説：
When a Development Team realizes mid-Sprint that it may not be able to deliver all planned Sprint Backlog Items, this situation should be handled throughempiricism, not concern or blame. As a Scrum Master, I would reassure the team and guide them back to Scrum principles.
First, I would remind the team that in Scrum they donot commit to delivering all Sprint Backlog Items.
Instead, the Scrum Team commits todoing their very best to achieve the Sprint Goal. Discovering additional work, complexity, or unknowns during the Sprint is expected, especially in complex product development. The Sprint Backlog is a forecast, not a fixed contract.
Second, I would help the team assess theimpact of what they have discovered. If the newly discovered work is minor and theSprint Goal is still within reach, the team can continue as planned while adapting the Sprint Backlog as needed. This reflects normal inspection and adaptation during the Sprint.
Third, if the impact is significant and threatens the Sprint Goal, the Development Team should have a focused discussion aboutif and how the Sprint Goal can still be met. This may involve changing the approach, reducing scope while preserving the Sprint Goal, or identifying alternative ways to deliver the intended value.
In such cases, theProduct Owner should be involvedin the conversation. Including the Product Owner increases transparency and enables faster value-based decision-making, such as re-negotiating scope or adjusting priorities while keeping the Sprint Goal intact. This collaboration ensures that adaptations are aligned with product value.
