"Yes! And..." is probably the most basic rule of improv. It means accept what is offered and build on it.
It's the basis for all good improv performances.
It's also the basis for creative thought and innovation.
In fact, most recently it played a large part in one of the most innovative conferences I've seen,
The Green Meetings Industry Council's 2011 Sustainable Meetings Conference .
GMIC 2011 Conference Chair Elizabeth Henderson was tasked with finding a way to use concepts from the book "Total Engagement" by Byron Reeves, in a conference situation. The book explores the use of gaming concepts in business.
She created an outline of concepts, such as teams, role playing, instant feedback, scoring and competition, and applied it to a potential conference set-up.
Then she gathered some volunteers and put them into teams.
"One was my 'Collaboration team'. I told them to use improv rules…that is, they needed to say “yes, and…” and build on ideas," she explained in a recent Engage365 interview.
