Scrum Professional Scrum Master level III (PSM III) - PSM-III

A Scrum Team has been working on a product for nine Sprints. A new Product Owner comes in, understanding he is accountable for the Product Backlog. However, he is unsure about his responsibilities.
Which two activities are part of the Product Owner role according to Scrum?

According to Scrum, theProduct Owneris accountable formaximizing the value of the productand for effectiveProduct Backlog management. Two key activities that are explicitly part of this role are:
1. Ordering the Product Backlog to Maximize Value
The Product Owner is responsible forordering the Product Backlogso that the most valuable work is done first. This ordering reflects:
* Business and customer value,
* Risk and uncertainty,
* Strategic goals and learning from previous Sprints.
Through this activity, the Product Owner ensures that the Scrum Team is always working on what matters most.
2. Ensuring Product Backlog Items Are Transparent, Clear, and Understood The Product Owner ensures that Product Backlog Items are:
* Clearly expressed,
* Transparent to the Scrum Team and stakeholders,
* Understood well enough for Developers to select them during Sprint Planning.
This does not mean writing detailed requirements alone, butcollaboratingso that shared understanding exists.

Describe the difference between feature and component teams, and how they hold up when viewed from the perspective ofthe Scrum Guide.

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.

The Product Owner remains distant. He/she has handed over the required Product Backlog for the Sprint but is not collaborating with the Development Team during the Sprint. What are valuable actions for a Scrum Master?

A distant Product Owner represents arisk to value delivery, transparency, and empiricism. While the Product Owner has provided a Product Backlog for the Sprint, lack of collaboration during the Sprint undermines learning and informed decision-making. As a Scrum Master, the focus should be oncoaching, enabling collaboration, and addressing systemic impediments, not substituting for the Product Owner.
1. Make the Impact Transparent
The Scrum Master should help make the impact of the Product Owner's absencevisible:
* Reduced ability to clarify Product Backlog Items,
* Slower decision-making when discoveries occur,
* Increased risk to the Sprint Goal and product value.
This transparency should be established through respectful conversations with the Product Owner and, if needed, through Scrum events such as the Sprint Retrospective.
2. Coach the Product Owner on Accountability
The Scrum Guide states that the Product Owner is accountable formaximizing valueandProduct Backlog management, which requires ongoing collaboration with Developers. The Scrum Master should coach the Product Owner to understand that handing over a backlog at Sprint Planning isnot sufficientand that availability during the Sprint is essential for empiricism.
3. Enable Better Collaboration Without Replacing the Product Owner
The Scrum Master should help create opportunities for collaboration, such as:
* Encouraging regular clarification moments during the Sprint,
* Improving Product Backlog refinement so fewer questions remain unanswered,
* Helping Developers prepare focused questions to use limited Product Owner availability effectively.
However, the Scrum Master mustnot take over Product Owner responsibilities, as this would blur accountabilities.
4. Address Organizational Causes
If the Product Owner's distance is due to workload, role confusion, or organizational pressure, this becomes an organizational impediment. The Scrum Master should raise this issue with leadership and help the organization understand the risk of an unavailable Product Owner to product outcomes.

When many Development Teams are working on a single product, what best describes the definition of
"done?"

When many Development Teams are working on a single product, there must beone shared Definition of Done (DoD)that applies toall teamsand tothe entire product Increment.
Single, Shared Definition of Done
Scrum requires that each Increment beusable and potentially releasable. When multiple teams contribute to one product, this means:
* There isone product, not multiple team products,
* There must therefore beone Definition of Donethat ensures consistency, quality, and transparency across all teams.
Having different Definitions of Done per team would result in:
* Inconsistent quality,
* Integration problems,
* Loss of transparency,
* Increments that are "Done" in isolation but not at the product level.
Integrated Increment-Level Definition of Done
The shared Definition of Done must includeintegration criteria, ensuring that:
* Work from all teams is integrated,
* The combined Increment meets quality and compliance standards,
* The product can be inspected and potentially released.
In scaled Scrum (e.g., Nexus), unintegrated work is explicitlynot considered Done, regardless of whether individual teams believe their work is complete.
Ownership and Evolution
While Developers collectively create and adhere to the Definition of Done, it applies at theproduct level, not the team level. As the product and organization mature, the Definition of Done may beexpanded, but it must always remain shared and transparent.
