Why does software development present additional difficulties?
Because its not physically present
The Nexus Guide (Page 2)
What is the best description of Nexus Sprint Planning?
Appropriate representatives from each SCRUM Team meet to discuss and review the refined Product Backlog.
The Nexus Guide (Page 4)
What is the first topic the cross-team Refinement should address?
Decomposing Product Backlog Items into enough detail in order to understand which teams might deliver them, and in what sequence over upcoming Sprints.
The Nexus Guide (Page 8)
What is the major difference between SCRUM Guidelines and Nexus Guidelines with respect to teams working together?
More attention is paid to dependencies and interoperation between SCRUM Teams, delivering one “Done” Integrated Increment at lease every Sprint.
The Nexus Guide (Page 3)
Who in the Nexus Plans out the Nexus Sprint Plan?
Each SCRUM Team plans its own Sprint, interacting with other teams as appropriate.

What is the “Nexus Sprint Backlog”?
An artifact that exists to assist with transparency during the Sprint, and collects the items which are refined and made ready, to indicate which team will perform the work during the Sprint.
The Nexus Guide (Page 3)
If all members of the SCRUM Teams, may do all of the work in the Nexus - then how do the SCRUM Teams select the most appropriate members to do the specific work?
Base on Dependencies
The Nexus Guide (Page 4)
Do SCRUM Teams within the Nexus maintain a joint Sprint Backlog?
No - All SCRUM Teams maintain their individual Sprint Backlog.
The Nexus Guide (Page 3)
Where should all product backlog items selected for the Sprint and their dependencies be visualized?
On the Nexus Sprint Backlog
The Nexus Guide (Page 7)
How do you know if enough refinement meetings have been performed during a Sprint?
If the Product Backlog items are ready and selectable with minimum dependencies during the Sprint Planning meeting.
The Nexus Guide (Page 9)
What part of the Nexus Sprint Retrospective allows the individual Sprint Teams to form actions to address issues during their individual SCRUM Team Sprint Retrospectives?
Each SCRUM Team holding their own Sprint Retro as described in the SCRUM Framework.
The Nexus Guide (Page 8)
What are the 3 parts to a Nexus Sprint Retrospective?
1 - Opportunity for appropriate representatives for across a Nexus to meeting and identify issues that have impacted more than a single team.
2 - Each SCRUM Team holding their own Sprint Retrospective as described in the SCRUM Framework.
3 - Opportunity for appropriate representative from the SCRUM Teams to meet again and agree on how to visualize and track identified actions.
The Nexus Guide (Page 7 - 8)
What is the second topic the cross-team Refinement should address? Why?
Identify Dependencies to provide visualization across teams and Sprints.This helps the team re-order the sequencing and allocation of their work in order to minimize the number of cross-team dependencies.
The Nexus Guide (Page 8 - 9)
In the Diagram what does 5 Represent?
Integrated IncrementThe Nexus Guide - Cover
The Nexus Guide (Page 10)
Who does the Nexus work during the Sprint?
“All work may be done by all members of the SCRUM Teams, as cross-functional members of the Nexus.”
The Nexus Guide (Page 4)
What roles are related to the “Nexus Integration Team”?
- Nexus Product Owner
- Nexus SCRUM Master
- Nexus Integration Team Members
The Nexus Guide (Page 3)
What is the difference between the Nexus and SCRUM Team Product Owner?
None they are the same person - there can only be one Product Backlog - and one owner.
The Nexus Guide (Page 5)
Are Nexus ceremonies (Events) time-boxed?
Yes
The Nexus Guide (Page 6)
What is the role of the Product Owner in Sprint Planning?
Providing domain knowledge and guides selection and priority decisions.
The Nexus Guide (Page 6)
What is the focus of the Nexus Daily SCRUM?
Identify if any integration issues exist.
The Nexus Guide (Page 4)
What is the focus of the Nexus Daily SCRUM?
- Inspect the current state of the integrated increment
- ID Integration Issues
- Review/ID newly discovered cross-team dependencies
The Nexus Guide (Page 7)
What allows the teams to monitor and minimize dependencies?
Visualization
The Nexus Guide (Page 8)
What best describes the “Nexus Framework”?
An exoskeleton that rests on top of multiple SCRUM Teams when they are combined to created an Integrated Increment.
The Nexus Guide (Page 3)
Should the SCRUM Team Sprint Planning and Nexus Sprint Planning be co-located?
Yes - the teams can continue to share newly found dependencies.
The Nexus Guide (Page 6)
What can be described as an exoskeleton that rests on top of multiple SCRUM Teams when they are combined to create an Integrated increment?
The Nexus Framework
The Nexus Guide (Page 3)
When should the Product Backlog be refined with dependencies identified and removed or minimized?
Prior to Nexus Sprint Planning.
The Nexus Guide (Page 7)
What makes the SCRUM Team select Product Backlog items and any dependencies transparent?
The Nexus Sprint Backlog
The Nexus Guide (Page 4)
Name the 4 Nexus Artifacts.
- Product Backlog
- Nexus Goal
- Nexus Sprint Backlog
- Integrated Increment
The Nexus Guide (Page 9)
What three questions should be asked at each Nexus Daily SCRUM?
- Was the previous day’s work successfully integrated? (If not, why not)
- What new dependencies have been identified
- What information needs to be shared across teams in the Nexus
The Nexus Guide (Page 7)
What is the Nexus “Integrated Increment”?
The sum of all integrated work completed by the Nexus. The Integrated Increment must be useable and potentially releasable which means it much meet the definition of “Done”.
The Nexus Guide (Page 9)
What is the key factor is Nexus artifacts being effective?
Artifact Transparency.
The Nexus Guide (Page 10)
What common scaling dysfunctions every Retrospective should address?
- Was any work left undone? Did the Nexus Generate Technical debt?
- Were all artifacts, particularly code, frequently (as often as every day) successfully integrated.
- Was the software successfully built, tested and deployed often enough to prevent the overwhelming accumulation of unresolved dependencies?
The Nexus Guide (Page 8)
Nexus Artifacts What is described as - Existing to assist with transparency during the Sprint, yet allowing SCRUM Teams to maintain their individual Sprint Backlogs?
The Nexus Sprint Backlogs -
The Nexus Guide (Page 3)
What does the Nexus Integration Team members do next if their primary responsibility is satisfied?
They may also work as Development (SCRUM) Team members in one or more SCRUM Teams.
The Nexus Guide (Page 6)
Which takes precedence the Nexus or SCRUM Team responsibilities? Why?
NexusIt helps ensure that the work to resolve issues that may affect teams (including other SCRUM Teams) has priority.
The Nexus Guide (Page 5)
What are the goals of the “Nexus Integration Team” with respect to deriving the best outcomes?
- Coordinate
- Coach
- Supervise
The Nexus Guide (Page 3)
Why is having complete or near complete information vital?
Incomplete or partial information will lead to incorrect or flawed decisions. The impact in a Nexus is greatly magnified as the Nexus is composed of individual SCRUM Teams.
The Nexus Guide (Page 10)
How can dependencies be reduced between SCRUM Teams using Nexus?
To the extent that
- requirements
- team members’ knowledge
- code/test artifactsare mapped to the same SCRUM Teams.
The Nexus Guide (Page 2)
What key ceremony does the following best describe”Appropriate representatives from each SCRUM Team meet to identify shared challenges.”
The Nexus Sprint Retrospective
The Nexus Guide (Page 4)
What Nexus artifact contains all the work and is constantly refined by the Nexus & SCRUM Teams?
The Product Backlog
The Nexus Guide (Page 9)
Who is responsible for the definition of “Done” in Nexus?
The Nexus Integration Team, with input from the Product Owner guided by the SCRUM Master.
The Nexus Guide (Page 6)
What is the purpose of the Nexus Framework?
Its a framework for
- developing and sustaining scaled product
- software development initiativesusing SCRUM as a building block.
The Nexus Guide (Page 2)
What should each SCRUM Team do next after the Nexus Sprint Retrospective?
Hold the SCRUM Team Retrospective. Appropriate representatives from each team meet again to discuss any actions needed based on shared challenges to provide bottom-up intelligence.
The Nexus Guide (Page 4)
What is the test for unacceptable technical debt?
When integration occurs, and it remains unclear that all dependencies are resolved. Unresolved dependencies remain hidden in the code and test base, lowering the overall value of the software.
