Activity #7, Step #2
Identify Cooperation Failures

During this step, you must think about the events that may lead to situations that are not totally controlled by the system designer and thus can be seen as "harmful".

The aim of this step is to point at "wrong" interactions between entities and the system. The AMAS theory calls these events and situations "cooperation failures". These events can be viewed as a kind of "exceptions".

These cooperation failures must be highlighted within the previously identified use cases and ADELFE provides a specific notation to do this: dotted arrows.
