This part of the book covers a collection of mistakes often found in use-case models. This collection should be used to detect that something may be wrong in the model. Although rare, there may be a good reason why a model matches one of these erroneous models and still be correct.
All chapters in this part are organized in the same way:
Name of mistake—. A descriptive name of the error in a few words
Fault—. A short description of the mistake
Incorrect model—. A use-case model illustrating the mistake
Discussion—. A discussion on why this is an incorrect model
Way out—. Hints on what to do to correct the incorrect model
The chapters presenting the mistakes are sorted alphabetically within this part.
