Example: what is scrum of scrums

Let us assume an active project on
which seven teams are currently working.
Each team is responsible to lead its own
scrum meeting. But, in order to coordinate
and communicate with different teams, 
it is required to organize a separate
scrum meeting. There is one team leader 
from every team, known as ambassador,
who is responsible to represent his
team in the scrum of scrums.
• The scrum meeting organized to hold a
coordination between scrum teams is
known as the scrum of scrums.
