An interrelationship diagram consists of a series of boxes or circles, each representing an issue to be considered. The boxes are organized in a radial pattern, and lines connecting the boxes indicate the relationships between the various issues. As denoted below, the strength of an Interrelationship Diagram comes through its ability to visualize relationships between complex processes. As arrows are plotted on the board, participants will see connections between ideas. In the interrelationship diagram above, "Overly optimistic promise dates for follow-up calls" is a key issue and, of course, would cause patients to expect a phone call faster than the group believes it can deliver it.
