Sprint Length of Scrum Teams In a Nexus
In a Nexus should the sprint length be the same for the different scrum teams? If no, then wouldn't it cause issues with respect to creating a done integrated increment? How would the different scrum events like retrospective, review and planning be coordinated if the sprint lengths vary? What is cadence with respect to a Nexus the sprint length or the velocity?
Could someone help with examples or articles, please?
Each team in a Nexus must respect and observe the Nexus Sprint (e.g. a 4 week cadence), but there's nothing to stop a team from having shorter Sprints which align to it (e.g. a 2 week cadence). That is a matter of implementation choice. For example, if a team is dependent upon another's output during a Nexus Sprint, planning shorter sprints could be a way to resolve the dependency.
