English: Subway Fare Card Machine Decision Diagram:
Decision/Action Diagrams - These diagrams are similar to functional flows except that decision points are added. Each function is expressed as a "verb-noun" combination with occasional adjectives or other modifiers. Each decision point is placed in a diamond-shaped outline symbol and written in question form. The question must be binary, answerable by a "yes" or "no" response. Both functional action blocks and decision diamonds are labeled with reference numbers, similar to those used for functional flow diagrams. These are necessary to ensure traceability. Shown above is a Decision Diagram for a subway fare card machine. |
