Use Cases: Patterns and Blueprints

Part V. Common Mistakes

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.
