Scrum SPS Scaled Professional Scrum (SPS) Exam Exam Practice Test

According to the Nexus Guide1, the Nexus Sprint Review is an event where the Nexus presents the Done Integrated Increment that was built over the Sprint and collects feedback from the stakeholders. The Integrated Increment is the combined work of all the Scrum Teams in the Nexus that meets the Definition of Done. The Nexus Guide also states that the Nexus Integration Team is a specialized Scrum Team that provides services and guidance to the Scrum Teams in the Nexus to ensure that the Integrated Increment is produced every Sprint.

In the scenario, the teams are not using a shared environment, which implies that they are not integrating their work frequently and effectively. This means that there is no single Integrated Increment that can be inspected and adapted by the stakeholders. This also suggests that the Nexus Integration Team is lacking or nonexistent, or that it is not fulfilling its role of facilitating integration and resolving dependencies. Without a Nexus Integration Team and a shared environment, the Nexus cannot deliver a valuable product Increment that meets the Product Goal.

The Sprint length and the integration phase are not relevant to the scenario. The Sprint length is determined by the Nexus based on the complexity and uncertainty of the product, and it should be less than a month. The integration phase is not a separate phase in Nexus, but a continuous activity that happens throughout the Sprint. Therefore, A and B are not correct answers.

When multiple Scrum Teams are working together on the same product, each team should not maintain a separate Product Backlog. According to the Scrum Guide, the Product Backlog is the single source of truth for the product, and it is owned and managed by the Product Owner 11. Having multiple Product Backlogs for the same product would create confusion, inconsistency, and duplication among the Scrum Teams and the stakeholders. It would also compromise the transparency, the alignment, and the value of the product development.

Instead of having separate Product Backlogs, the Scrum Teams should work from a common Product Backlog that reflects the vision, the goal, and the priorities of the product 22. The Product Owner should collaborate and communicate with the Scrum Teams and the stakeholders to ensure that the Product Backlog is clear, refined, and ordered. The Scrum Teams should coordinate and integrate their work to deliver a single Integrated Increment that meets the Definition of Done and the Product Goal every Sprint 33.

A Nexus Integration Team is not responsible for actually doing the integration work during the Sprint. The Nexus Integration Team is a specialized Scrum Team that provides services and guidance to the Scrum Teams in the Nexus to ensure that the Integrated Increment is produced every Sprint 11. However, the Nexus Integration Team is not accountable for the integration of the work of the individual Scrum Teams, as this is the responsibility of the Scrum Teams themselves 22. The Nexus Integration Team helps the Scrum Teams to coordinate, coach, and supervise the application of Nexus and the operation of Scrum, but it does not take over their work or accountability 33. Therefore, the statement is false.

The Nexus Sprint Review is an event where the Nexus, consisting of multiple Scrum Teams, presents the Integrated Increment to the stakeholders for inspection and feedback 1. The Integrated Increment is the sum of all the work done by the Scrum Teams in a Sprint that meets the Definition of Done 1. The purpose of the Nexus Sprint Review is to inspect the outcome of the Sprint, discuss the progress toward the Product Goal, discuss any changes in the environment, and collaborate on what to do next 2.

In Scenario A, the Nexus Sprint Review is not conducted effectively. The teams are not using a shared environment to demonstrate the Integrated Increment, but rather showing their individual work. This means that the stakeholders cannot see the whole product and how it works together. The teams are also delaying the integration of their work, which can lead to quality issues, technical debt, and increased complexity 1. The stakeholders do not provide much feedback, which means that the Nexus cannot adapt to the changing needs and expectations of the customers and users. The event ends without any clear outcomes or next steps.

If this pattern continues for multiple Sprints, the effects may be:

• Quality will degrade as the teams delay creating a single Integrated Increment. This is answer B. By not integrating their work frequently and continuously, the teams will face more challenges and risks in ensuring that the product is functional, reliable, and usable. The teams will also miss the opportunity to validate their assumptions and learn from the feedback on the Integrated Increment 1.
• Ability to adapt will suffer as the stakeholders continue to disengage and not give feedback. This is answer D. By not engaging the stakeholders in a meaningful dialogue and collaboration, the Nexus will lose the insight and direction that the feedback provides. The Nexus will also risk building the wrong product or features that do not meet the needs and expectations of the customers and users. The stakeholders will also lose trust and confidence in the Nexus and the product 2.

The other two answers are not correct because:

• There will be more and more work to inspect so teams will need their own individual Sprint Reviews. This is answer A. This is not a valid effect because the Nexus Sprint Review replaces the individual Scrum Team Sprint Reviews 1. The Nexus Sprint Review is not a time for each team to present their work, but rather for the Nexus to present the Integrated Increment. The teams should not need their own Sprint Reviews, but rather focus on integrating their work and delivering a valuable product 1.
• Empiricism will suffer as the teams cannot produce a shared velocity. This is answer C. This is not a valid effect because velocity is not a measure of empiricism. Empiricism is the principle of making decisions based on observation, inspection, and adaptation 1. Velocity is a measure of the amount of work done by a team or a Nexus in a Sprint. Velocity is not a mandatory artifact or metric in Scrum or Nexus, and it does not reflect the quality or value of the work done 1.

The best way to help the two teams that are continually dependent on each other to manage their work is to ensure the appropriate representatives from both teams are present during Cross-Team Refinement. Cross-Team Refinement is an optional event in Nexus that allows the Scrum Teams to collaborate and coordinate on the Product Backlog items that have dependencies or require integration 11. By having the representatives from both teams present during this event, they can identify and resolve the dependencies, clarify the requirements, align the expectations, and plan the work for the next Sprint. This will improve the transparency, the quality, and the value of the Integrated Increment.

The other options are not advisable for the following reasons:

• The Nexus Integration Team should not be responsible for integrating the work of these two Scrum Teams, as this would create a bottleneck and a hand-off. The Nexus Integration Team is a specialized Scrum Team that provides services and guidance to the Scrum Teams in the Nexus to ensure that the Integrated Increment is produced every Sprint 11. However, the Nexus Integration Team is not accountable for the integration of the work of the individual Scrum Teams, as this is the responsibility of the Scrum Teams themselves 22.
• Reorganizing these two Scrum Teams so that one is responsible for development and one is responsible for integration is not a good idea, as this would create a silo and a separation of concerns. The Scrum Teams in a Nexus should be cross-functional and self-organizing, meaning that they have all the skills and abilities to deliver a potentially releasable product Increment every Sprint 11. Separating the development and the integration tasks would compromise the collaboration, the feedback, and the agility of the Scrum Teams.
• Merging the two Scrum Teams together is not a viable solution, as this would create a large and unwieldy team. The Scrum Guide states that the optimal size of a Scrum Team is between three and nine members 33. Merging two Scrum Teams together would exceed this limit and create challenges in communication, coordination, and decision-making. Moreover, merging the two teams would not necessarily eliminate the dependencies, as they may still exist within the larger team or with other teams in the Nexus.

A Nexus is a framework for scaling Scrum that enables multiple Scrum Teams to work on a single product 1. A Nexus has one Product Backlog, which is an ordered list of the work to be done by the Scrum Teams in the Nexus 1. The Product Backlog has a single source of requirements and priorities for the product, and it is managed by the Product Owner, who is accountable for maximizing the value of the product and the work performed and integrated by the Scrum Teams 1. Having one Product Backlog for a Nexus ensures that the Scrum Teams have a common vision, goal, and alignment for the product 23. Therefore, the statement is true.

The purpose of the Nexus Sprint Retrospective is to plan ways to increase quality and effectiveness across the whole Nexus 1. It is not to review the feedback from the Sprint Review, which is the purpose of the Nexus Sprint Review 1. It is not to ensure all Scrum Teams are working on the same improvement actions, which is a possible outcome but not the main goal of the event 2. It is not to identify underperforming team members, which is not a constructive or collaborative approach to scaling Scrum 3. The Nexus Sprint Retrospective follows a three-step process: first, representatives from each Scrum Team identify issues that affect multiple teams; second, each Scrum Team conducts its own Sprint Retrospective; and third, representatives from each team meet again to discuss any actions needed based on the shared challenges 145. The Nexus Sprint Retrospective enables continuous improvement across the Nexus by inspecting and adapting the Nexus framework, the integrated work, the processes, the tools, and the interactions among the Scrum Teams 1.

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.

The best way to improve the ability of the Scrum Teams in a Nexus to produce an Increment for the next Sprint is to reduce the amount of work that the teams pull into the Sprint. This will allow the teams to focus on delivering a high-quality and valuable product Increment that meets the Definition of Done and the Product Goal. Reducing the amount of work also reduces the complexity and dependencies among the teams, which makes integration easier and faster.

The other options are not advisable for the following reasons:

• Asking the Nexus Integration Team to extend the Sprint to allow more time for integration is not consistent with the Scrum principles and values. The Sprint length should be fixed and consistent throughout the product development, and it should be less than a month. Extending the Sprint would compromise the feedback loop, the transparency, and the adaptability of the Nexus 11.
• Reducing the number of Scrum Teams to reduce complexity is not a viable solution, as it would also reduce the capacity and the productivity of the Nexus. The number of Scrum Teams in a Nexus should be based on the size and the scope of the product, and it should not exceed nine teams 11. Reducing the number of teams would also disrupt the existing team dynamics and collaboration.
• Adding another Scrum Team to the Nexus to increase capacity is not a good idea, as it would increase the complexity and the dependencies among the teams. Adding another team would also require more coordination and communication, which would consume more time and resources. Moreover, adding another team would not necessarily increase the value or the quality of the product Increment 22.

The Nexus Sprint Retrospective is an event where the Nexus, consisting of multiple Scrum Teams, inspects and adapts its processes, tools, interactions, and dependencies to improve its quality and effectiveness 11. The Nexus Sprint Retrospective occurs after the Nexus Sprint Review and before the next Nexus Sprint Planning 11. The Nexus Sprint Retrospective has two parts: a first part where representatives from each Scrum Team identify shared challenges and opportunities, and a second part where each Scrum Team conducts its own Sprint Retrospective 23.

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 Scrum Teams in the Nexus 11. The Nexus Integration Team has the overall responsibility for ensuring the Nexus Sprint Retrospective occurs 11. The Nexus Integration Team facilitates the first part of the Nexus Sprint Retrospective, where the representatives from each Scrum Team share their insights and challenges 11. The Nexus Integration Team also participates in the second part of the Nexus Sprint Retrospective, where each Scrum Team reflects on its own performance and improvement actions 11. The Nexus Integration Team helps the Scrum Teams to identify and resolve any cross-team impediments or dependencies that may affect the quality and delivery of the Integrated Increment 11.

The other three answers are not correct because:

• The Scrum Master on the Nexus Integration Team. This is answer A. This is not a valid answer because the Scrum Master on the Nexus Integration Team is not the only one responsible for ensuring the Nexus Sprint Retrospective occurs. The Scrum Master on the Nexus Integration Team is a member of the Nexus Integration Team, but not the sole accountable person for the event. The Scrum Master on the Nexus Integration Team helps to facilitate the Nexus Sprint Retrospective, but does not own or control it 11.
• Any Scrum Master from the Nexus. This is answer B. This is not a valid answer because any Scrum Master from the Nexus does not have the authority or the responsibility to ensure the Nexus Sprint Retrospective occurs. Any Scrum Master from the Nexus is a member of a Scrum Team, but not a member of the Nexus Integration Team. Any Scrum Master from the Nexus helps to facilitate the Sprint Retrospective of their own Scrum Team, but does not have the visibility or the influence over the other Scrum Teams or the Nexus as a whole 11.
• The Developers. This is answer D. This is not a valid answer because the Developers do not have the responsibility for ensuring the Nexus Sprint Retrospective occurs. The Developers are the people who do the work of delivering a potentially releasable Increment of product value in each Sprint 11. The Developers participate in the Nexus Sprint Retrospective, but they do not organize or facilitate it. The Developers provide feedback and suggestions for improvement, but they do not have the accountability or the authority to ensure the Nexus Sprint Retrospective occurs 11.

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.
