"Beginning with the very simplest definition, a case is a story. This story describes a factual series of actions that occurred in the past. When a case is written as a teaching or learning tool, the reader is expected to do one of two things: (1) make a decision or recommendation to the protagonist for a course of action to pursue, or (2) perform an analysis/evaluative description of the action that has already taken place"
