Stringency is a component of the dramaturgical list of ingredients of improvisation theater. Stringency means that the happenings on the stage follow or build on each other logically and comprehensibly. Very simply, one thing results from the other. The current promises of the scene or the story are redeemed. Conflicts and problems of the players are worked on. The frame, which was created by previous actions, is not disrupted, i.e. inappropriate or too many play ideas or proposals are avoided; it is taken from what is available.
In additional, many of the usual mistakes lead to the story not being stringent, some would-be originality, holding patterns, but also blocks additionally lead to the frame created by the players cannot be directly picked up and carried forward, but is thwarted.
