Cause and effect diagrams document all the factors that contribute to or affect a given situation: all the causes, that is, that lead to a certain effect. They are also called Ishikawa, fishbone, or characteristic diagrams.

The Cause and Effect Diagram template opens a drawing page that already contains a spine shape (effect) and four category boxes (causes) to help start your drawing. This template also provides a variety of shapes that represent primary and secondary causes that can be used to add even greater detail.
