SPS Scaled Professional Scrum (SPS) Exam Questions and Answers

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.

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 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.

Scrum Teams do not have to report back to the Nexus Integration Team right after their individual Daily Scrums. 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 14. The Nexus Daily Scrum is an event where the Nexus Integration Team and one or two representatives from each Scrum Team meet to inspect the current state of the Integrated Increment and identify any integration issues or dependencies 12. The Nexus Daily Scrum takes place before the individual Daily Scrums of the Scrum Teams 13. The purpose of the Nexus Daily Scrum is to coordinate any challenges and dependencies of the day that all teams should be aware of, not to report back to the Nexus Integration Team 12. The individual Daily Scrums of the Scrum Teams are focused on planning how to fix the integration problems and achieve the Sprint Goal 13. Therefore, the statement is false.

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.

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 artifacts in the Nexus framework is the Integrated Increment, which is the integrated aggregation of all work completed by all the Scrum Teams in a Nexus 11.

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 11. 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.

What could help this Nexus create a single Integrated Increment for inspection at the Nexus Sprint Review is:

• Enforce a Definition of Done across the entire Nexus that includes integration. This is answer B. This is a valid answer because the Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product 11. The Definition of Done is used to assess when work is complete on the product Increment 11. The Definition of Done is defined by the Nexus and applies to all the work done by the Scrum Teams in the Nexus 11. The Definition of Done should include integration as one of the criteria, which means that the work done by the teams should be integrated frequently and continuously throughout the Sprint 11. By enforcing a Definition of Done that includes integration, the Nexus can ensure that the Integrated Increment is usable and potentially releasable, which means it meets the quality standards and expectations of the stakeholders 11.

The other three answers are not correct because:

• Reserve the last few days of the Sprint for testing and integration. This is answer A. This is not a valid answer because reserving the last few days of the Sprint for testing and integration is not a good practice. It implies that the teams are not testing and integrating their work throughout the Sprint, but rather doing it at the end of the Sprint. This can lead to quality issues, technical debt, and increased complexity 11. It also reduces the time available for inspection and adaptation, which are essential for empiricism and agility 11.
• Have the Nexus Integration Team integrate all the work as early as possible. This is answer C. This is not a valid answer because the Nexus Integration Team is not the only one responsible for integrating all the work. 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 11. The Nexus Integration Team facilitates the integration of the work, but does not do it for the teams 11. The teams are responsible for integrating their own work and delivering a potentially releasable Increment of product value in each Sprint 11.
• Have a Sprint dedicated to integration. This is answer D. This is not a valid answer because having a Sprint dedicated to integration is not consistent with Scrum or Nexus. Scrum and Nexus require that the teams deliver a potentially releasable Increment of product value in each Sprint 11. Having a Sprint dedicated to integration means that the teams are not delivering any value or receiving any feedback in that Sprint 11. It also means that the teams are accumulating technical debt and complexity that will make integration more difficult and risky 11.

The purpose of Nexus Sprint Planning is to coordinate the activities of all Scrum Teams within a Nexus for a single Sprint 1. To do this effectively, the Nexus needs to have a clear understanding of the dependencies between the teams and the work items, and to communicate and collaborate with each other and any outside experts as needed. Therefore, the best practices for this Nexus are:

• A. Ensure all Scrum Teams and outside experts are available during the Nexus Sprint Planning event and have a way of quickly communicating with each other. They should try to be together in the same room or use technology that makes it seem as if they are in the same room. This practice enables the Nexus to have a shared understanding of the Product Backlog, the Product Goal, and the Nexus Sprint Goal, and to resolve any issues or questions that may arise during the planning. It also allows the Nexus to leverage the expertise of the outside specialists who are required for some of the work 2.
• D. Visualize the known dependencies in the Product Backlog for all to see. As Scrum Teams select work for the Sprint, they can easily check for any dependent work and communicate with other teams. This practice helps the Nexus to identify and manage the dependencies between the teams and the work items, and to optimize the flow of value delivery. It also supports transparency and alignment within the Nexus 3.

The other two practices are not effective for this Nexus because:

• B. Plan one Scrum Team’s Sprint at a time before moving on to the next team. This way you can account for time zone differences and can communicate dependencies across all teams. This practice is not optimal because it does not allow the Nexus to plan the Sprint as a whole, and to adjust the work allocation and sequence based on the dependencies and the Nexus Sprint Goal. It also creates delays and inefficiencies in the planning process, and reduces the collaboration and feedback opportunities among the teams 4.
• C. Have the Nexus Integration Team select the work for each of the individual Scrum Teams. This allows the Nexus Integration Team to control the dependencies. This practice is not consistent with the Nexus framework, which states that the Nexus Integration Team does not select the work for the Scrum Teams, but rather facilitates the integration and delivery of the work done by the Scrum Teams. It also undermines the self-organization and empowerment of the Scrum Teams, and reduces their ownership and accountability for the work 1.

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.

When a Nexus, which is a group of approximately three to nine Scrum Teams working on the same product, faces many dependencies during Nexus Sprint Planning, it can use some techniques to manage them effectively. One technique is to reorganize team members between the teams to eliminate cross-team dependencies. This can be done by forming feature teams or component teams based on the nature of the work and the skills required. By doing so, the Nexus can reduce the need for coordination and integration across teams, and increase the autonomy and ownership of each team 1122. Therefore, statement B is correct.

Another technique is to reorder Product Backlog items to better accommodate dependencies. This can be done by applying dependency management techniques such as dependency mapping, dependency inversion, dependency breaking, and dependency prioritization. By doing so, the Nexus can identify, visualize, resolve, and minimize the dependencies that affect the delivery of the Integrated Increment, which is the combined work of all the Scrum Teams in the Nexus that meets the Nexus Sprint Goal 334455. Therefore, statement D is also correct.

Statement A is incorrect because it implies that the Nexus Integration Team, which is a group of people who are accountable for ensuring the integration and delivery of the Integrated Increment, should do the dependent work ahead of the Sprint for the teams. This would create a bottleneck and a single point of failure, as well as undermine the self-organization and collaboration of the Scrum Teams 1122. Statement C is incorrect because it suggests that the Nexus should extend the Sprint so that the teams can have more time to complete the dependent work. This would violate the Scrum principle of time-boxing, which ensures that the Nexus delivers value frequently and incrementally, and inspects and adapts its process regularly 1122.
