"Improvisers would say that the principle of "yes-anding" is at the heart of improvisation. It means that individuals accept the offer made to them and build on it. It is a simple concept, but challenging to implement. It means that jokes are not made at the expense of other people, individuals do not impose themselves on the scene in a controlling fashion; individuals do not just survive in the scene, they work actively to build it; and individuals do no put, or leave, one another out on a limb. Individuals in many organizations will find it difficult to leave up to this concept of teamwork."
