What is Scrum's relation to Empiricism / Empirical Process Control? 正解:
解説:
Scrum is fundamentally based onEmpiricism, also referred to asEmpirical Process Control. This means that Scrum recognizes that complex work, such as software development, cannot be fully understood or predicted upfront. Instead, decisions are made based onexperience, observation, and evidence, forming a continuous closed feedback loop.
Empirical Process Control rests on three pillars:Transparency, Inspection, and Adaptation. Scrum provides a structured framework of roles, events, and artifacts that explicitly support and reinforce each of these pillars.
Transparency
Transparency ensures that all significant aspects of the process and product are visible to those responsible for the outcome. In Scrum, transparency is created through clearly defined artifacts such as theProduct Backlog, Sprint Backlog, and Product Increment, each governed by a shared Definition of Done. Scrum Events further enhance transparency by creating regular opportunities to share progress, challenges, and current state.
Without transparency, inspection would be misleading and ineffective.
Inspection
Scrum prescribes frequent and regularinspectionof both the product and the process. Each Scrum Event serves as an inspection point:
* TheDaily Scruminspects progress toward the Sprint Goal,
* TheSprint Reviewinspects the Increment and adapts the Product Backlog,
* TheSprint Retrospectiveinspects the team's ways of working.
These inspections are intentionally timeboxed and lightweight to avoid excessive overhead while still enabling timely feedback.
Adaptation
Inspection is meaningful only if it leads toadaptation. Scrum explicitly enables adaptation by allowing changes to plans, processes, and backlog content based on what is learned. The Sprint Backlog may be adapted during the Sprint, the Product Backlog is adapted after the Sprint Review, and team practices are adapted following the Sprint Retrospective.
Closed Feedback Loop
Together, transparency, inspection, and adaptation form aclosed feedback loop. Scrum's short iterations (Sprints) ensure that learning occurs frequently, enabling the Scrum Team and stakeholders to respond quickly to change, reduce risk, and improve outcomes over time.

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.
質問 # 33
One of the Scrum events is the Sprint Review. How does the Sprint Review enable empiricism? What would the impact be if some members of the development team were not present? 正解:
解説:
TheSprint Reviewis a key Scrum Event that directly enablesempiricism, which is the foundation of Scrum.
Empiricism is based on making decisions using what is known, observed, and learned, supported by the pillars oftransparency, inspection, and adaptation. The Sprint Review operationalizes these pillars at the product level.
How the Sprint Review Enables Empiricism
First, the Sprint Review createstransparencyby making the current state of the product visible. During the event, the Scrum Team presents a"Done" Product Incrementthat meets the Definition of Done. Stakeholders can see and often use the actual product rather than relying on reports or assumptions. This shared visibility ensures that discussions are grounded in reality.
Second, the Sprint Review enablesinspection. The Scrum Team and stakeholders jointly inspect the Increment and assess progress toward product goals. The Developers provide context about what was delivered, what was not, and what challenges were encountered. This inspection is focused on outcomes and value, not individual performance.
Third, the Sprint Review supportsadaptation. Based on the inspection and feedback, new insights emerge about customer needs, market conditions, risks, and opportunities. The Product Owner uses this information to adapt the Product Backlog, reordering items, adding new work, or refining existing items. This completes the empirical feedback loop by ensuring future decisions are based on the latest evidence.
Impact of Development Team Members Not Attending the Sprint Review
If some Developers are not present at the Sprint Review, empiricism is weakened.
First,transparency decreases. Developers possess critical, first-hand knowledge about implementation details, technical trade-offs, constraints, and risks. Without their presence, stakeholders receive an incomplete picture of the Increment and its implications.
Second,inspection becomes less effective. Stakeholders may ask questions about behavior, limitations, or quality that only Developers can accurately answer. The absence of Developers limits meaningful dialogue and reduces the quality of inspection.
Third,adaptation suffers. Decisions about what to do next-such as changes to scope, priorities, or technical direction-depend on accurate understanding. Without Developers participating, adaptations to the Product Backlog may be based on assumptions rather than evidence, increasing the risk of poor decisions.
Finally, excluding Developers underminesScrum Values, particularlyRespect and Openness, by treating the Sprint Review as a reporting event rather than a collaborative working session. This can lead to disengagement and reduced shared ownership of product outcomes.
質問 # 34
In what way does Scrum encourage ethical behaviour, doing "the right thing", in software development? 正解:
解説:
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.
質問 # 35
Decisions to optimise value and control risk are made based on the perceived state of the artefacts. What events and practises can improve transparency over the artefacts? Explain why. 正解:
解説:
In Scrum, decisions to optimize value and control risk depend on theperceived state of the artifacts. If artifacts are not transparent, inspection and adaptation become ineffective, leading to poor decisions. Scrum therefore defines specificevents and practicesto improve transparency and support empirical decision- making.
Scrum Events That Improve Artifact Transparency
Sprint Planningimproves transparency by aligning the Scrum Team on the current state of theProduct Backlogand theProduct Increment. The Product Owner explains backlog ordering and objectives, while Developers assess what is feasible based on the current Increment and Definition of Done. This shared understanding reduces risk by creating a realistic Sprint Goal.
Daily Scrumimproves transparency of theSprint Backlog. Developers inspect progress toward the Sprint Goal and make visible emerging risks, dependencies, and impediments. Daily inspection ensures that deviations are discovered early, enabling fast adaptation and reducing delivery risk.
Sprint Reviewimproves transparency of theProduct IncrementandProduct Backlog. Stakeholders directly inspect the Increment and provide feedback. This exposes assumptions, validates value, and informs Product Backlog adaptation, helping optimize future value and reduce market risk.
Sprint Retrospectiveimproves transparency ofprocess-related aspectsthat influence the artifacts. By inspecting ways of working, tools, skills, and the Definition of Done, the team identifies improvements that increase artifact quality and reliability over time.
Practices That Improve Transparency
Aclear and shared Definition of Doneensures transparency of the Product Increment. It creates a common understanding of what "complete" means and prevents hidden work or misleading progress.
Product Backlog refinementimproves transparency by clarifying Product Backlog Items, making assumptions explicit, and reducing uncertainty. Although not a formal Scrum event, refinement supports better inspection and forecasting.
Frequent integration and testingimprove transparency by making the real state of the Increment visible early and often. This reduces the risk of late surprises and unintegrated work.
Visible metrics and information radiators(such as Sprint Goals, Sprint Backlogs, and progress toward objectives) help stakeholders and teams understand the state of work without relying on reports or interpretations.
