Important Scrum SPS Exam Questions

Answer: C, D

Explanation:

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.

Answer: C

Explanation:

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.

Answer: C

Explanation:

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.

Answer: A, D, E

Explanation:

Moving away from component teams toward feature teams is a significant change that should be considered carefully. Here are some of the factors that should be taken into account:

Feature teams have less communication overhead than component teams, as they are able to deliver end-to-end customer features without relying on other teams or components 11. This reduces the complexity and the dependencies among the teams, and improves the transparency and the feedback loop. Feature teams also foster more collaboration and cross-functional learning among the team members, as they have to work on different aspects of the product 22.

When making this change, it helps to have support from the organization, as it may require a shift in the culture, the structure, and the processes of the company 33. The organization should provide the necessary resources, training, and coaching to the teams to help them adopt the feature team model. The organization should also align its goals, incentives, and metrics with the feature team approach, and remove any barriers or impediments that may hinder the teams' performance 44.

Productivity may decrease when making this kind of change, as the teams may face some challenges and difficulties in the transition period 55. For example, the teams may have to learn new skills, technologies, or domains that they are not familiar with. The teams may also have to deal with legacy code, technical debt, or integration issues that may slow down their delivery. The teams may also experience some resistance or conflict from the existing component teams or stakeholders. Therefore, the teams should expect some temporary setbacks and losses in productivity, and focus on continuous improvement and adaptation.

The other options are not correct for the following reasons:

With feature teams, it is not easier to calculate the productivity per team, as productivity is not a simple or straightforward metric to measure in software development [6]. Productivity depends on various factors, such as the quality, the value, the complexity, and the customer satisfaction of the product. Moreover, focusing on the productivity per team may create a competitive or individualistic mindset among the teams, rather than a collaborative or collective one. The teams should focus on delivering the best possible product Increment that meets the Product Goal and the Definition of Done, rather than on maximizing their productivity [7].

You can do Scrum without feature teams, as Scrum does not prescribe any specific team structure or organization [8]. Scrum only requires that the Scrum Team is cross-functional, self-organizing, and accountable for delivering a potentially releasable product Increment every Sprint [9]. However, feature teams are generally more aligned with the Scrum values and principles, as they enable the teams to deliver customer-centric features faster and more frequently, and to respond to changes more effectively [10]. Therefore, feature teams are recommended, but not mandatory, for Scrum.

Answer: B

Explanation:

Creating a communication plan is not enough to fully address the coordination challenges that arise when many Scrum Teams work on the same product. A communication plan is a document that outlines the objectives, methods, channels, and frequency of communication among the stakeholders of a project or product 1. While a communication plan is useful for ensuring clarity, transparency, and alignment among the Scrum Teams and other parties involved, it does not address other aspects of coordination, such as integration, dependency management, alignment of goals and vision, and cross-team collaboration 2.

To effectively coordinate multiple Scrum Teams working on the same product, a communication plan should be complemented by other practices and frameworks, such as:

Nexus: Nexus is a framework for scaling Scrum that consists of three to nine Scrum Teams working together to deliver an Integrated Increment every Sprint 3. Nexus provides roles, events, artifacts, and rules that help the Scrum Teams coordinate, integrate, and align their work, while maintaining the Scrum values and principles 4.

Scrum of Scrums: Scrum of Scrums is a technique for scaling Scrum that involves a regular meeting of representatives from each Scrum Team to share progress, identify dependencies, resolve issues, and align on the product vision and goal . Scrum of Scrums helps the Scrum Teams communicate and collaborate effectively, while minimizing the overhead and complexity of coordination .

Communities of Practice: Communities of Practice are groups of people who share a common interest, skill, or domain, and who meet regularly to exchange knowledge, ideas, and best practices . Communities of Practice help the Scrum Teams learn from each other, improve their skills, and foster a culture of continuous improvement .
