Scrum Professional Scrum Master level III (PSM III) - PSM-III Exam Practice Test
Describe the difference between feature and component teams, and how they hold up when viewed from the perspective ofthe Scrum Guide.
Correct Answer:
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.

During a retrospective, one of the more junior developers confesses he has a hard time getting his opinion heard. Whendiscussing the work to be done, the more experienced developers often don't let him finish his sentences or disregard what hehas to say. What Scrum Values are touched upon here?
Correct Answer:
The situation described directly touches on several coreScrum Values, which guide behavior and collaboration within Scrum Teams. In particular, the values ofCourage, Respect, and Opennessare most prominently involved.
First, the value ofCourageis demonstrated by the junior developer. Speaking up about feeling unheard, especially in front of more experienced colleagues, requires personal courage. Scrum encourages team members to be brave in raising difficult or uncomfortable issues so that problems can be addressed rather than ignored. Without courage, important impediments to collaboration and effectiveness would remain hidden.
Second, the situation highlights a lack ofRespectin team interactions. Scrum emphasizes that Scrum Team members respect each other as capable, independent individuals. Interrupting a colleague or disregarding their input-regardless of seniority-undermines this value. Respect is essential for effective collaboration and for creating an environment where all team members can contribute fully.
Third, the value ofOpennessis central to this scenario. Scrum Teams are expected to be open about challenges, feedback, and differing perspectives. Openness also means being receptive to ideas from all team members, independent of role, experience level, or background. Disregarding input from a junior developer contradicts Scrum's emphasis on openness and reduces the quality of decision-making.

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.
Correct Answer:
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.

The process of regular inspection and adaptation employs knowledgeable and skilled inspectors. What are two ways in which the Product Owner takes the lead in the inspection process?
Correct Answer:
TheProduct Ownertakes the lead in inspection by focusing onproduct value and direction, ensuring that learning from evidence directly informs future decisions.
1. Inspecting and Ordering the Product Backlog Based on Evidence
The Product Owner continuouslyinspects the Product Backlogusing information gained from:
* Delivered Increments,
* Stakeholder feedback,
* Market changes and risks.
By ordering and refining the Product Backlog, the Product Owner leads inspection of whether the backlog still reflects themost valuable and relevant work, ensuring that adaptation is based on evidence rather than assumptions.
2. Leading Product Inspection During the Sprint Review
The Product Owner leads inspection during theSprint Reviewby framing the conversation around:
* The Product Goal,
* What value the Increment delivers,
* What has been learned.
By engaging stakeholders in inspecting the Increment and guiding discussions about what to do next, the Product Owner ensures that feedback is transformed intoProduct Backlog adaptation.
