Suggestion

Two Owners are better than one

So why is it important to ensure a group has at least two owners? The short answer is continuity. A group without an owner will not be effectively managed. The membership might require changing or external guests may need to be added. The lifecycle of the group needs to be managed, whether that be archiving or extending it life beyond agreed lifecycle rules.

A single-owner represents a risk because people can leave organisations, they can be sick, on vacation or change their role. Multiple owners reduce that risk, increase continuity and help ensure owners are replaced if for whatever reason they no longer manage a particular group.
