Example of a meeting
Several people agree to meet at 9:00 to write a
document. Two arrive at 9:30, and one doesn’t show
up at all. One person takes some time to tell another
what happened at the last meeting. At about 10:00 the
people start discussing new items, though there is no
set agenda. The people discuss the title for 30 minutes,
including 10 minutes on the font sizes. For about 45
minutes, they brainstorm elements of the heart of their
document. They set another meeting for the next day
and adjourn without assigning tasks.
