Scrum Scaled Professional Scrum SPS Exam Questions

Answer : C

The Definition of Done is a set of quality standards that apply to the Integrated Increment, which is the combined work of all the Scrum Teams in the Nexus that meets the Nexus Sprint Goal 11. The Definition of Done creates transparency and alignment among the Scrum Teams and the stakeholders, and ensures that the Integrated Increment is potentially releasable 22. The Definition of Done can evolve over time as the Nexus learns from its experience and feedback, and as the product complexity and quality expectations change 33. The best place to discuss and update the Definition of Done is at the Nexus Sprint Retrospective, which is an event that occurs at the end of the Sprint where the Nexus inspects and adapts its processes, tools, and interactions 11. The Nexus Integration Team, which is a group of people who are accountable for ensuring the integration and delivery of the Integrated Increment, is responsible for the Definition of Done, but they can involve the other Scrum Team members and stakeholders in the discussion and decision 1144. Therefore, statement C is the correct answer.

Statement A is incorrect because it implies that the Nexus Integration Team can unilaterally change the Definition of Done without consulting the other Scrum Teams or stakeholders, which would undermine the transparency and collaboration that are essential for scaling Scrum 1144. Statement B is incorrect because it suggests that the Definition of Done is owned by the larger development organization, which may not be familiar with the specific needs and challenges of the Nexus, and that the changes are communicated by stakeholders, who may not have the technical expertise or authority to do so 1144. Statement D is incorrect because it assumes that the Scrum Masters have the sole power to decide on changes to the Definition of Done, which would exclude the input and agreement of the Nexus Integration Team, the other Scrum Team members, and the stakeholders 1144.

Answer : D

The purpose of Nexus Sprint Retrospective is all of the above, meaning that it aims to:

Plan ways to increase quality and effectiveness across the whole Nexus. The Nexus Sprint Retrospective is a formal opportunity for a Nexus to inspect and adapt itself and create a plan for improvements to be enacted during the next Sprint to ensure continuous improvement 11.

To inspect how the last Sprint went with regards to individuals, teams, interactions, processes, tools, and its Definition of Done. The Nexus Sprint Retrospective follows the same format and principles as the Scrum Team Sprint Retrospective, but at a larger scale. The Nexus inspects the aspects of the product development that affect the Nexus as a whole, such as the collaboration, the integration, the dependencies, the quality, and the value 22.

To complement the Scrum Teams' Sprint Retrospectives by using bottom-up intelligence to focus on issues that affect the Nexus as a whole. The Nexus Sprint Retrospective does not replace the Scrum Teams' Sprint Retrospectives, but rather enhances them by using the input and output from the individual teams to identify and address the shared challenges and opportunities 33.

Answer : B, D

The purpose of the Nexus Sprint Backlog is to provide a view of dependent Product Backlog items in a Sprint and to make dependencies transparent to the Scrum Teams 15. The Nexus Sprint Backlog is a composite of the Product Backlog items from the Sprint Backlogs of the individual Scrum Teams, and it is used to highlight dependencies and the flow of work during the Sprint. It is updated throughout the Sprint as more is learned 21324354.

The other answers are not correct for the following reasons:

A . To make the work of the Nexus Integration Team transparent. This answer is not accurate because the Nexus Sprint Backlog does not only show the work of the Nexus Integration Team, but also the work of all the Scrum Teams in the Nexus. The Nexus Integration Team is responsible for facilitating the integration and delivery of the work done by the Scrum Teams, but it does not select or assign the work for them 15.

C . To visualize all Product Backlog items. This answer is not true because the Nexus Sprint Backlog does not contain all the Product Backlog items, but only the ones that the developers in the Nexus believe are necessary to achieve the Nexus Sprint Goal. The Product Backlog is the single source of requirements for the product, and it is managed and ordered by the Product Owner 15.

Answer : A, C

The Nexus framework is a way of scaling Scrum for multiple teams working on a single product. The Nexus framework uses Scrum as its building block and extends it only where necessary to minimize and manage dependencies between teams 11. The Nexus framework defines the accountabilities, events, and artifacts that bind and weave together the work of the teams in a Nexus 11. One of the key events in the Nexus framework is the Nexus Sprint Planning, which is used to coordinate the activities of all teams in the Nexus for a single Sprint 11.

In Scenario B, the Nexus is developing a complex product with different parts that only certain teams can work on. There are also some highly specialized individuals outside the Nexus that are required for some of the work. In past Sprints, the Nexus encountered challenges dealing with the many dependencies between teams. Dependencies are the relationships between the work items that affect the order, timing, or outcome of the work 22. Dependencies can cause delays, rework, waste, and lower quality 22. Therefore, it is important to identify and resolve dependencies as early and as often as possible 22.

The two strategies that would be most effective in dealing with the dependencies are:

Discover and document dependent work during Cross-Team Refinement of the Product Backlog, so teams are aware of dependencies before Nexus Sprint Planning. This will allow Nexus Sprint Planning to focus on resolving dependencies for the upcoming Sprint. This is answer A. This is a valid strategy because Cross-Team Refinement is an activity where representatives from each team in the Nexus meet to decompose and refine the Product Backlog items into smaller pieces of work that can be delivered by a single team or multiple teams 11. By doing this, the teams can discover and document the dependent work that needs to be done by other teams or external parties 11. This will help the teams to be aware of the dependencies before the Nexus Sprint Planning and to prepare for them 11. This will also allow the Nexus Sprint Planning to focus on resolving the dependencies for the upcoming Sprint, rather than spending time on identifying them 11.

During Nexus Sprint Planning, have appropriate representatives from each team in the Nexus briefly meet to discuss dependencies for the upcoming Sprint. This conversation will help their individual team's Sprint Planning. This is answer C. This is a valid strategy because Nexus Sprint Planning is an event where the Nexus, consisting of the Product Owner and appropriate representatives from each team, meet to plan the Sprint 11. The purpose of Nexus Sprint Planning is to coordinate the activities of all teams in the Nexus for a single Sprint 11. The result of Nexus Sprint Planning is a Nexus Sprint Goal that aligns with the Product Goal and a Nexus Sprint Backlog that contains the work to be done by the teams to achieve the Nexus Sprint Goal 11. During Nexus Sprint Planning, the representatives from each team can briefly meet to discuss the dependencies for the upcoming Sprint and how to resolve them 11. This conversation will help their individual team's Sprint Planning, where they can create their own team Sprint Goal and team Sprint Backlog that support the Nexus Sprint Goal and the Nexus Sprint Backlog 11.

The other two answers are not correct because:

Have the Nexus Integration Team order the Nexus Sprint Backlog. They should control and resolve the dependencies. This is answer B. This is not a valid strategy because the Nexus Integration Team is not the owner or the controller of the Nexus Sprint Backlog. The Nexus Integration Team is a role that consists of the Scrum Master, the Product Owner, and other members who are responsible for coordinating, coaching, and supervising the integration of the work done by the teams in the Nexus 1[1][5]. The Nexus Integration Team facilitates the Nexus Sprint Planning, but does not order or dictate the Nexus Sprint Backlog 1[1][5]. The Nexus Sprint Backlog is owned and managed by the Nexus, not by the Nexus Integration Team 1[1][5]. The Nexus Integration Team helps the teams to identify and resolve the dependencies, but does not control or impose them 1[1][5].

Gather all people in the Nexus into a 48-hour Nexus Sprint Planning event. Discover, document, and resolve dependencies during this time. This is answer D. This is not a valid strategy because gathering all people in the Nexus into a 48-hour Nexus Sprint Planning event is not feasible, efficient, or effective. The Nexus Sprint Planning is not meant to be a long and exhaustive event that involves all people in the Nexus 11. The Nexus Sprint Planning is meant to be a short and focused event that involves only the Product Owner and appropriate representatives from each team in the Nexus 11. The Nexus Sprint Planning is not meant to be the only time to discover, document, and resolve dependencies 11. The Nexus Sprint Planning is meant to be the time to coordinate the activities of the teams for the upcoming Sprint and to create a Nexus Sprint Goal and a Nexus Sprint Backlog 11. The discovery, documentation, and resolution of dependencies should be done continuously throughout the Sprint, not only during the Nexus Sprint Planning 11.

Answer : A, D

The true statements regarding using Scrum for large-scale product delivery are:

A . Splitting a team member's time between multiple Scrum Teams is often less productive than focusing that team member on a single team's Sprint Backlog. This statement is true because splitting a team member's time between multiple teams can cause context switching, communication overhead, coordination challenges, and reduced commitment and accountability. It can also reduce the team's ability to self-organize and deliver a potentially releasable product increment at the end of each Sprint. Therefore, it is recommended that team members focus on one team's Sprint Backlog and work as a cross-functional and cohesive unit 1122.

D . A well-structured and refined Product Backlog can minimize and often eliminate dependencies between multiple Scrum Teams working together on a product during a Sprint. This statement is true because a well-structured and refined Product Backlog can help the Product Owner and the Scrum Teams to identify and prioritize the most valuable and feasible work items, and to decompose them into smaller and independent pieces that can be delivered by one or more teams. This can reduce the complexity and risk of integration and dependency management, and increase the flow and quality of value delivery 3344.

The other statements are false for the following reasons:

B . Scrum requires all team members work full time on a single team. This statement is false because Scrum does not prescribe how team members allocate their time or effort. Scrum only defines the roles, events, artifacts, and rules that guide the empirical process of product development. However, as mentioned above, it is often more productive and effective for team members to focus on one team's Sprint Backlog and avoid splitting their time between multiple teams [5].

C . Changes to the core Scrum framework are needed to be successful with Scrum at large-scale. This statement is false because Scrum is a lightweight and adaptable framework that can be applied to any complex product development context, regardless of the size or scale. Scrum does not need to be changed or modified to be successful at large-scale, but rather scaled up or down according to the needs and goals of the product organization. There are various frameworks and approaches that can help scale Scrum, such as Nexus, LeSS, SAFe, and Scrum@Scale, but they all adhere to the core principles and values of Scrum [6] [7].

Answer : B

The most important concern for multiple Scrum Teams when they are working from the same Product Backlog is minimizing dependencies between teams. Dependencies are the relationships or constraints that exist between the work items or the teams that affect the delivery of the product 11. Dependencies can cause delays, rework, waste, and quality issues, and they can reduce the agility and value delivery of the Scrum Teams 2233. Therefore, minimizing dependencies between teams is a critical concern for scaling Scrum effectively 112233.

Statement A is incorrect because meeting original scope projections is not a primary concern for multiple Scrum Teams working from the same Product Backlog. Scrum does not prescribe a fixed scope for the product, but rather embraces change and adaptation based on feedback and learning 44. The Product Backlog is a dynamic and emergent artifact that reflects the current understanding of the product vision, goals, and requirements 44. The Product Owner is responsible for managing the Product Backlog and ordering the items in a way that maximizes the value of the product and the work of the Scrum Teams 44. Therefore, meeting original scope projections is not a relevant or realistic concern for scaling Scrum.

Statement C is incorrect because clear definition of requirements is not the most important concern for multiple Scrum Teams working from the same Product Backlog. While having clear and well-defined requirements is desirable and beneficial for the Scrum Teams, it is not always possible or necessary in a complex and uncertain environment 44. Scrum does not require detailed upfront specifications, but rather encourages empirical discovery and experimentation through frequent delivery and feedback 44. The Product Backlog items are refined and clarified by the Product Owner and the Developers as they collaborate and learn more about the product and the users 44. Therefore, clear definition of requirements is not the most critical concern for scaling Scrum.

Statement D is incorrect because making sure there is enough work for everyone on every team is not the most important concern for multiple Scrum Teams working from the same Product Backlog. Scrum does not focus on maximizing the utilization of the Scrum Team members, but rather on maximizing the value of the product and the work of the Scrum Teams 44. The Scrum Teams are self-organizing and cross-functional, which means they can decide how to do their work and have all the skills needed to create a potentially releasable Increment 44. The Scrum Teams pull work from the Product Backlog in agreement with the Product Owner, and they commit to delivering an Integrated Increment that meets the Nexus Sprint Goal 1144. Therefore, making sure there is enough work for everyone on every team is not the most essential concern for scaling Scrum.

Answer : C

The best way for multiple Scrum Teams to deliver a valuable and useful Increment in a Sprint is to complete work that integrates with all of the other work from other Scrum Teams on the initiative. This means that the Scrum Teams collaborate and coordinate their work to produce a single Integrated Increment that meets the Definition of Done and the Product Goal. The Integrated Increment is the combined work of all the Scrum Teams that is potentially releasable and provides value to the customers and stakeholders 11.

The other options are not correct for the following reasons:

Each Scrum Team delivering done Increments of its own area of responsibility and integrating them into a whole product during stabilization prior to release is not a good idea, as it violates the Scrum principles and values. The Scrum Guide states that the Scrum Team delivers a product Increment that is usable and valuable at the end of every Sprint, not at the end of the release 22. Delaying the integration until the stabilization phase would compromise the transparency, the feedback, and the adaptability of the Scrum Teams.

Each Scrum Team providing a unique done Increment that includes the team's added functionality is not a good idea, as it does not ensure that the product Increment is integrated and consistent across the initiative. The Scrum Guide states that the product Increment is the sum of all the Product Backlog items completed during a Sprint and all previous Sprints 22. If each Scrum Team provides a unique Increment, they may not be aligned with the Product Goal and the Definition of Done, and they may create conflicts or dependencies with other Scrum Teams.

Functionality not integrated with the work of other Scrum Teams being delivered as unintegrated Increments to demonstrate the value created by the Scrum Teams unable to completely integrate their Increments is not a good idea, as it does not ensure that the product Increment is done and valuable. The Scrum Guide states that the product Increment must be usable and meet the Definition of Done 22. If some functionality is not integrated with the work of other Scrum Teams, it may not be usable or valuable to the customers and stakeholders, and it may introduce technical debt or quality issues.
