Coordination fault is realized when the operation of a specific component does not match that of the other components.
During the operation, the operational scenario is implicit, and different components assume different active operational scenarios. The problem raises when a certain component is in an exceptional state, while the operation of the other components continues normally, because they do not have the system level information about the active scenario. In such cases, the system might not respond properly to the situation change, resulting in coordination fault.
Coordination faults are typical of systems that do not synchronize continuously, because the system constraints are not specified in the behavior documents.
