Scaled Professional Scrum (SPS) Exam Questions and Answers
True or False: A Nexus Integration Team is accountable for ensuring that a Integrated
Increment is produced at least once a Sprint.
Options:
True
False
Answer:
BExplanation:
A Nexus Integration Team is not accountable for ensuring that an Integrated Increment is produced at least once a 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.
What are three benefits of self-managing Scrum Teams?
(choose the best three answers)
Options:
Increased rule compliance.
Increased self-accountability.
Increased creativity.
Increased commitment.
Increased accuracy of estimates.
Answer:
B, C, DExplanation:
Self-managing Scrum Teams are teams that internally decide who does what, when, and how, rather than being directed by others outside the team 11. Self-managing Scrum Teams have the following benefits:
- Increased self-accountability: Self-managing Scrum Teams are accountable for delivering a potentially releasable product Increment every Sprint that meets the Definition of Done and the Product Goal 22. They are also accountable for following the Scrum values and principles, and for inspecting and adapting their work and process 33. By being accountable for their own decisions and actions, self-managing Scrum Teams are more responsible, transparent, and quality-oriented.
- Increased creativity: Self-managing Scrum Teams have the autonomy and the empowerment to choose how best to accomplish their work, rather than being constrained by predefined methods or instructions 44. They also have the opportunity to experiment, learn, and innovate, as they are encouraged to try new ideas and approaches to solve complex problems [5]. By having the freedom and the support to be creative, self-managing Scrum Teams are more productive, adaptive, and valuable.
- Increased commitment: Self-managing Scrum Teams have the ownership and the involvement in their work, as they are part of the planning, execution, and review of the product development [6]. They also have the trust and the collaboration among the team members, as they share a common goal and vision, and respect each other’s skills and abilities [7]. By having the sense of belonging and the teamwork, self-managing Scrum Teams are more motivated, engaged, and satisfied.
The Scrum Teams in a Nexus find they have simply too much work each Sprint to do to deliver
a valuable and useful Increment. What could they try to improve their ability to produce an
Increment for the next Sprint?
(choose the best answer)
Options:
Reduce the amount of work that the teams pull into the Sprint.
Ask the Nexus Integration Team to extend the Sprint to allow more time for
integration.
Reduce the number of Scrum Teams to reduce complexity.
Add another Scrum Team to the Nexus to increase capacity.
Answer:
AExplanation:
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 purpose of a Nexus Sprint Retrospective is to:
(choose the best two answers)
Options:
Enable bottom-up intelligence to improve how the Scrum Teams in a Nexus are
working together.
Provide a forum for management to see how the Nexus is performing.
Allow for inspection and adaptation of both individual Scrum Teams and a
Nexus.
Provide a single meeting to inspect and adapt how all Scrum Teams work
together.
Answer:
A, CExplanation:
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.
The purpose of the Nexus Integration Team is to:
(choose the best two answers)
Options:
Raise transparency.
Manage the Nexus.
Be accountable that an Integrated Increment is produced.
Integrate the work of the Scrum Teams.
Answer:
A, CExplanation:
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 12. The Nexus framework defines the accountabilities, events, and artifacts that bind and weave together the work of the teams in a Nexus 12. One of the key roles in the Nexus framework is the Nexus Integration Team, which is a team of people who are responsible for coordinating, coaching, and supervising the integration of the work done by the Scrum Teams in the Nexus 21.
The purpose of the Nexus Integration Team is to:
- Raise transparency. This is answer A. This is a valid answer because the Nexus Integration Team is responsible for raising transparency across the Nexus 213. Transparency is one of the pillars of empiricism, which is the principle of making decisions based on observation, inspection, and adaptation 12. The Nexus Integration Team helps to raise transparency by facilitating the Nexus events, such as the Nexus Sprint Planning, the Nexus Daily Scrum, the Nexus Sprint Review, and the Nexus Sprint Retrospective 213. The Nexus Integration Team also helps to raise transparency by visualizing the Nexus Sprint Backlog, which is a representation of the work across the Nexus that has dependencies 213. The Nexus Integration Team also helps to raise transparency by communicating and collaborating with the stakeholders, the Product Owner, and the Scrum Teams 213.
- Be accountable that an Integrated Increment is produced. This is answer C. This is a valid answer because the Nexus Integration Team is accountable that an Integrated Increment is produced 214. The Integrated Increment is the integrated aggregation of all work completed by all the Scrum Teams in a Nexus 124. The Integrated Increment is the potentially releasable outcome of the Sprint, which means it meets the quality standards and expectations of the stakeholders 124. The Nexus Integration Team is accountable that an Integrated Increment is produced by ensuring that the work done by the Scrum Teams meets the Definition of Done, which is a formal description of the state of the Increment when it meets the quality measures required for the product 214. The Nexus Integration Team is also accountable that an Integrated Increment is produced by helping the Scrum Teams to identify and resolve any integration issues or dependencies that may affect the quality and delivery of the product 214.
The other two answers are not correct because:
- Manage the Nexus. This is answer B. This is not a valid answer because the Nexus Integration Team is not the manager of the Nexus. 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 211. The Nexus Integration Team does not manage or control the Nexus, but rather supports and enables the Nexus 211. The Nexus is self-organizing and autonomous, which means it decides how to do its work and what work to do 124.
- Integrate the work of the Scrum Teams. This is answer D. This is not a valid answer because the Nexus Integration Team is not the one who integrates the work of the Scrum Teams. 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 211. The Nexus Integration Team facilitates the integration of the work, but does not do it for the teams 211. The teams are responsible for integrating their own work and delivering a potentially releasable Increment of product value in each Sprint 124.
How should Product Backlog items be chosen when multiple Scrum Teams work from the same
Product Backlog?
(choose the best answer)
Options:
The Scrum Teams choose the Weighted Shortest Job First.
The Developers pull work in agreement with the Product Owner.
Each Scrum Team takes an equal number of items.
The Scrum Team with the highest velocity pulls Product Backlog items first.
The Product Owner should provide each team with its own Product Backlog.
Answer:
BExplanation:
When multiple Scrum Teams work from the same Product Backlog, they should choose the Product Backlog items that they can deliver as part of an Integrated Increment, which is the combined work of all the Scrum Teams that meets the Nexus Sprint Goal 11. The Developers, who are the people in the Scrum Teams who are accountable for creating and delivering the Increment, should pull work in agreement with the Product Owner, who is the person who is accountable for maximizing the value of the product and the work performed and integrated by the Scrum Teams 11. The Developers and the Product Owner should collaborate to select the Product Backlog items that are most valuable, feasible, and aligned with the Nexus Sprint Goal 2233. Therefore, statement B is the correct answer.
Statement A is incorrect because it implies that the Scrum Teams choose the Weighted Shortest Job First, which is a prioritization technique that ranks Product Backlog items based on their value and cost 44. However, the Scrum Guide does not prescribe any specific technique for ordering the Product Backlog, and the Product Owner is the sole person responsible for managing the Product Backlog [5]. Statement C is incorrect because it suggests that each Scrum Team takes an equal number of items, which may not reflect the value, complexity, or dependencies of the items 1122. Statement D is incorrect because it assumes that the Scrum Team with the highest velocity pulls Product Backlog items first, which may not be the best way to optimize the value delivery and integration across the Nexus 1122. Statement E is incorrect because it proposes that the Product Owner should provide each team with its own Product Backlog, which would create confusion, inconsistency, and duplication of work. Having multiple Product Backlogs would also undermine the transparency and alignment that are essential for scaling Scrum 1122.
If two Scrum Teams are added to a product that previously had only one Scrum Team, what will
be the immediate impact on the productivity of the original Scrum Team?
(choose the best answer)
Options:
Its productivity is likely to stay the same.
Its productivity is likely to decrease.
Its productivity is likely to increase.
Answer:
BA Nexus Daily Scrum:
(choose the best two answers)
Options:
Provides a single meeting where all Scrum Teams can update the Sprint
Backlog.
Is the same as a Scrum-of-Scrums.
Provides input into each Scrum Team's individual Daily Scrums to help them
better plan their days work.
Is only for the Nexus Integration Team to plan their work for the next 24-hours.
Is an opportunity to make integration issues transparent.
Answer:
C, EExplanation:
The best answers for this question are:
- C. Provides input into each Scrum Team’s individual Daily Scrums to help them better plan their days work. This answer is correct because the Nexus Daily Scrum is an event that helps the Scrum Teams in a Nexus to coordinate their work and identify any integration issues or dependencies that may affect their progress toward the Nexus Sprint Goal. The appropriate representatives from each Scrum Team attend the Nexus Daily Scrum and share relevant information and feedback that can help their teams plan their work for the next 24 hours 112233.
- E. Is an opportunity to make integration issues transparent. This answer is also correct because the Nexus Daily Scrum is an event that enables the Scrum Teams in a Nexus to inspect the current state of the Integrated Increment and to make any integration issues or newly discovered cross-team dependencies transparent. The Nexus Daily Scrum also provides a forum for the Scrum Teams to collaborate and resolve any integration challenges or impediments that may arise during the Sprint 112244.
The other answers are not correct for the following reasons:
- A. Provides a single meeting where all Scrum Teams can update the Sprint Backlog. This answer is not accurate because the Nexus Daily Scrum is not a meeting where all Scrum Teams update the Sprint Backlog, but rather an event where appropriate representatives from each Scrum Team inspect the Integrated Increment and identify integration issues or dependencies. The Sprint Backlog is updated by each Scrum Team during their own Daily Scrum, which is a separate event from the Nexus Daily Scrum 1155.
- B. Is the same as a Scrum-of-Scrums. This answer is not true because the Nexus Daily Scrum is not the same as a Scrum-of-Scrums, which is a common practice for coordinating multiple Scrum Teams that is not part of the Scrum framework. The Nexus Daily Scrum is a specific event defined by the Nexus framework, which is a minimal extension of Scrum that enables multiple Scrum Teams to work together on a single product. The Nexus Daily Scrum has a clear purpose, structure, and outcome that differs from a Scrum-of-Scrums 112233.
- D. Is only for the Nexus Integration Team to plan their work for the next 24-hours. This answer is not correct because the Nexus Daily Scrum is not only for the Nexus Integration Team, but also for the appropriate representatives from each Scrum Team in the Nexus. The Nexus Integration Team is a special Scrum Team that facilitates the integration and delivery of the work done by the other Scrum Teams, but it does not plan the work for them. The Nexus Daily Scrum is an event that helps all the Scrum Teams in the Nexus to coordinate their work and identify any integration issues or dependencies 1155.
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 practices could this Nexus try in order to conduct Nexus Sprint Planning
more effectively?
(choose the best two answers)
Options:
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.
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.
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.
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.
Answer:
A, DExplanation:
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.
You have been assigned as the Scrum Master of six new Scrum Teams that will build one
product. What conditions should you strive for in this scenario?
(choose the best two answers)
Options:
There should be six Product Owners, one for each Scrum Team.
There should be six Product Owners, one of whom is chief Product Owner.
The product has one Product Backlog.
There should be only one Product Owner who is accountable for the success of
the product.
Each Scrum Team should have a separate Product Backlog.
Answer:
C, DExplanation:
When six new Scrum Teams are working on one product, they should form a Nexus, which is a framework for scaling Scrum 11. A Nexus has a single Product Owner who is accountable for maximizing the value of the product and the work performed and integrated by the Scrum Teams 1122. Therefore, statement D is correct.
A Nexus also works off a single Product Backlog, which is an ordered list of the work to be done by the Scrum Teams in the Nexus 11. The Product Backlog has a single source of requirements and priorities for the product, and it is managed by the Product Owner 1122. Therefore, statement C is also correct.
Statements A, B, and E are incorrect because they imply that each Scrum Team has its own Product Owner and Product Backlog, which would create confusion, inconsistency, and duplication of work. Having multiple Product Owners and Product Backlogs would also undermine the transparency and alignment that are essential for scaling Scrum 1122.
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 would you recommend to the two teams that are continually dependent on each other to
help them manage their work?
(choose the best answer)
Options:
The Nexus Integration Team should be responsible for integrating the work of these
two Scrum Teams.
Reorganize these two Scrum Teams so that one is responsible for development and
one is responsible for integration.
Merge the two Scrum Teams together.
Ensure the appropriate representatives from both teams are present during Cross-
Team Refinement.
Answer:
DExplanation:
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.
During Cross-Team Refinement, the ordered Product Backlog (1 through 9) is mapped out so
the Nexus can visualize dependencies. For example, PBI 5 for Team Orange is dependent on
Team Red completing PBI 1.
All else being equal, which PBI is most concerning?
(choose the best answer)
Options:
PBI 2, because it has the most dependencies.
PBI 1, because it is on the top of the Product Backlog.
PBI 1, because it is the first piece of work with a dependency.
PBI 2, because there is a dependency with a different team on work that occurs
within the same Sprint.
Answer:
DExplanation:
PBI 2 is the most concerning because it involves a cross-team dependency within the same Sprint, which can create challenges and risks for the integration and delivery of the product increment. According to the Online Nexus Guide1, dependencies should be minimized or eliminated as much as possible, and if they exist, they should be made transparent and resolved as early as possible. Cross-team dependencies within the same Sprint can cause delays, conflicts, rework, and waste, and reduce the quality and value of the product increment 234.
The other answers are not correct for the following reasons:
- A. PBI 2, because it has the most dependencies. This answer is not accurate because PBI 2 does not have the most dependencies, but only one dependency with PBI 1 from Team Red. PBI 3 has the most dependencies, as it depends on PBI 1, PBI 2, and PBI 4. However, PBI 3 is not as concerning as PBI 2, because its dependencies are not within the same Sprint, but across different Sprints. This means that PBI 3 can be refined and planned in advance, and the teams can coordinate and communicate their work more effectively 5.
- B. PBI 1, because it is on the top of the Product Backlog. This answer is not relevant because the position of PBI 1 on the Product Backlog does not indicate its level of concern, but its priority and value. The Product Backlog is ordered by the Product Owner based on various factors, such as business value, risk, complexity, and dependencies. PBI 1 may be on the top of the Product Backlog because it is the most valuable or urgent item, or because it is a prerequisite for other items, but it is not necessarily the most concerning item 6.
- C. PBI 1, because it is the first piece of work with a dependency. This answer is not true because PBI 1 is not the first piece of work with a dependency, but the first piece of work that other items depend on. PBI 1 does not have any dependencies itself, but it creates dependencies for PBI 2, PBI 3, and PBI 5. Therefore, PBI 1 is not as concerning as PBI 2, because it does not depend on any other item, and it can be completed independently by Team Red 5.
