3. Nexus is an exoskeleton that rests on top of
multiple Scrum Teams when they are combined
to create an Integrated Increment.
Nexus is consistent with Scrum and its parts will
be familiar to those who have worked on Scrum
projects.
The difference is that more attention is paid to
dependencies and interoperation between
Scrum Teams, delivering one “Done” Integrated
Increment at least every Sprint.
