NO.66 Scenario C: Dependencies and Product Backlog items During Nexus Sprint Planning, representatives from each of the 9-member Scrum Teams identify many dependencies. This 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. What techniques could help this Nexus manage their dependencies effectively? (choose the best two answers)
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.
NO.69 Scenario C: Dependencies and Product Backlog items During Nexus Sprint Planning, representatives from each of the 9-member Scrum Teams identify many dependencies. This 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. What should the Scrum Teams do to effectively deal with their dependencies? (choose the best answer)
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.
NO.73 How might the Nexus evolve its Definition of Done over time? (choose the best answer)
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.
NO.75 Scenario B: Six Team Nexus with complex dependencies A six team Nexus is developing a complex product, with different parts of the product that only certain Scrum Teams can work on. In fact, there are 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 Scrum Teams. Which of the following two strategies would be most effective in dealing with their dependencies? (choose the best two answers)
The Nexus framework is a way of scaling Scrum for multiple teams working on a single product.

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.
NO.77 Who has overall responsibility for ensuring Nexus Sprint Retrospective occurs? (choose the best answer)
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.
