Guideline: Scrum of Scrums
Main Description

The primary way of scaling Scrum to work with large teams is to coordinate a "Scrum of Scrums." With this approach each Scrum team proceeds as normal but each team also contributes one person who attends Scrum of Scrum meetings to coordinate the work of multiple Scrum teams. These meetings are analogous to the Daily Scrum Meeting, but do not necessarily happen every day. In many organizations, having a Scrum of Scrums meeting two or three times a week is sufficient.

The illustration below shows how a Scrum of Scrums approach allows Scrum to scale up (in this case to 243 people). Each cell represents one person on a Scrum team. The bottom of this illustration shows teams with nine developers on them. One person from each team (the differently colored cell) also participates in a Scrum of Scrum to coordinate work above that team. Then from those nine-person teams another person is selected (this time shown with diagonal lines) to participate in what might be called a Scrum of Scrums of Scrums.
