Question 38 - SPS discussion

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 112.

When multiple Scrum Teams work on a product at the same time, the statements that are true are:

The different Scrum Teams coordinate their work to deliver a single Increment. This is answer A. This is a valid answer because the different Scrum Teams in a Nexus are not working in isolation, but rather collaborating and coordinating their work to deliver a single Increment 113. The single Increment is the Integrated Increment, which is the sum of all the work done by the Scrum Teams in a Sprint that meets the Definition of Done 112. The single Increment is the potentially releasable outcome of the Sprint, which means it meets the quality standards and expectations of the stakeholders 112.

The Developers must integrate their work before the end of the Sprint. This is answer C. This is a valid answer because the Developers are the people who do the work of delivering a potentially releasable Increment of product value in each Sprint 114. The Developers must integrate their work before the end of the Sprint, which means they must combine and verify their work frequently and continuously throughout the Sprint 114. The integration of the work is essential for ensuring the quality and usability of the product, as well as for validating the assumptions and learning from the feedback 114.

The other three answers are not correct because:

Each Scrum Team develops one or more product components which the Nexus Integration team uses to assemble the Integrated Increment. This is answer B. This is not a valid answer because the Nexus Integration Team is not the one who assembles the Integrated Increment. 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[5]. The Nexus Integration Team facilitates the integration of the work, but does not do it for the teams 11[5]. The teams are responsible for integrating their own work and delivering a potentially releasable Increment of product value in each Sprint 11[5].

They are all on the same Scrum Team. This is answer D. This is not a valid answer because they are not all on the same Scrum Team. A Scrum Team is a small group of people who are cross-functional and self-organizing, and who deliver a potentially releasable Increment of product value in each Sprint 11[6]. A Scrum Team usually consists of one Scrum Master, one Product Owner, and a few Developers 11[6]. When multiple Scrum Teams work on a product at the same time, they are not on the same Scrum Team, but rather on different Scrum Teams that form a Nexus 11[6]. A Nexus is a group of three to nine Scrum Teams who work on a single product and who share a common Product Backlog, a common Definition of Done, and a common Sprint Goal 11[6].

The Scrum of Scrums assembles the components into an Integrated Increment. This is answer E. This is not a valid answer because the Scrum of Scrums is not a part of the Nexus framework. The Scrum of Scrums is a term that is sometimes used to describe a coordination mechanism for multiple Scrum Teams, where representatives from each team meet regularly to share information and align their work [7][7]. The Scrum of Scrums is not a formal event or role in Scrum or Nexus, and it is not the one who assembles the components into an Integrated Increment [7][7]. The teams are responsible for integrating their own work and delivering a potentially releasable Increment of product value in each Sprint 11[5].
