True or False: When using graphical models to stimulate discussion among software engineers (as in agile modeling), the models must be completely rigorous and use the notation with absolute precision.
Correct Answer
False
Explanation
When models are used to stimulate and focus discussion (as in agile modeling), they may be incomplete and can use the modeling notation informally. The purpose of the model is to stimulate discussion, not to serve as a precise formal specification. This is different from when models are used for documentation (must be correct) or for code generation (must be both complete and correct, with precise notation).
