The Nexus Sprint Review is an event that occurs at the end of the Sprint where the Nexus, which is a group of approximately three to nine Scrum Teams working on the same product, presents the Integrated Increment to the stakeholders and collects feedback 12. The Integrated Increment is the combined work of all the Scrum Teams in the Nexus that meets the Definition of Done and the Nexus Sprint Goal 1. The purpose of the Nexus Sprint Review is to inspect the Integrated Increment and adapt the Product Backlog based on new learnings 1. Therefore, statement A is correct.
The Nexus Sprint Review replaces individual Scrum Team Sprint Reviews because the focus is on the entire Integrated Increment rather than the work of each team 12. The Nexus Sprint Review is not a container for each individual Scrum Team’s Sprint Review, nor is it when individual Scrum Teams demo their work. These statements imply that the Nexus Sprint Review is a collection of separate Sprint Reviews, which is not the case. The Nexus Sprint Review is a single event that involves all the Scrum Teams and stakeholders in the Nexus 12. Therefore, statement B is also correct, and statements C and D are incorrect.

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 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 C, the Nexus Sprint Planning is not conducted effectively. The representatives from each of the 9-member Scrum Teams identify many dependencies, which makes it hard for them to choose the work they could pull into their individual teams for the next Sprint. No matter how they reorganize the Product Backlog items, they continually find more or new dependencies. 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.
What should the Scrum Teams do to effectively deal with their dependencies is:
Increase the frequency of Cross-Team Refinement to reduce dependencies. This is answer A. This is a valid answer 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 reduce the dependencies by breaking down the work into more manageable and independent units 11. The teams can also identify and resolve the dependencies before the Nexus Sprint Planning, which will make the planning easier and more effective 11. By increasing the frequency of Cross-Team Refinement, the teams can ensure that the Product Backlog items are ready and clear for the Nexus Sprint Planning 11.
The other three answers are not correct because:
Merge the two Scrum Teams together that have the most dependencies with each other. This is answer B. This is not a valid answer because merging the two Scrum Teams together that have the most dependencies with each other is not a good solution. It implies that the teams are not able to collaborate and coordinate effectively with each other, and that they need to be in the same team to work on the same product 11. It also increases the size and complexity of the merged team, which can reduce its agility and productivity 11. It also does not address the root cause of the dependencies, which may be related to the product or communication structure 22.
Institute quarterly meetings for planning out all dependencies between teams. This is answer C. This is not a valid answer because instituting quarterly meetings for planning out all dependencies between teams is not consistent with Scrum or Nexus. Scrum and Nexus require that the teams plan and deliver a potentially releasable Increment of product value in each Sprint, which is usually a few weeks long 11. Instituting quarterly meetings for planning out all dependencies between teams means that the teams are not planning or delivering any value or receiving any feedback in the Sprints 11. It also means that the teams are not able to adapt to the changing needs and expectations of the customers and users, which are essential for empiricism and agility 11.
All of the above. This is answer D. This is not a valid answer because none of the above answers are valid. Therefore, choosing all of them is not a valid answer either.

The Nexus Sprint Retrospective is an event that occurs at the end of the Sprint where the Nexus, which is a group of approximately three to nine Scrum Teams working on the same product, plans ways to increase quality and effectiveness across the whole Nexus 11. The purpose of the Nexus Sprint Retrospective is to inspect and adapt the Nexus framework, the integrated work, the processes, the tools, and the interactions among the Scrum Teams 11. Therefore, statement C is correct.
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 112233. The Nexus Sprint Retrospective enables bottom-up intelligence to improve how the Scrum Teams in a Nexus are working together, as it allows the teams to share their insights, learn from each other, and collaborate on solutions 44. Therefore, statement A is also correct.
Statement B is incorrect because the Nexus Sprint Retrospective is not a forum for management to see how the Nexus is performing, but rather a time for the Nexus to self-organize and self-improve 1144. Statement D is incorrect because the Nexus Sprint Retrospective is not a single meeting to inspect and adapt how all Scrum Teams work together, but rather a combination of three meetings that involve both individual and collective reflection and action 112233.

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 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.

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.
