Business Process Management (KM-BPM) |
With respect to business process, a well-designed business process could be able to
handle fault in order to prevent possible failures. |
A fault could influence KPIs and result in a failure. It
can be defined as a deviation from a desired KPI |
||
| Service Composition and
Coordination (KM-SC) |
A design process is necessary to identify and handle
faults at run time in a composite service |
A Monitoring mechanism could be applied to diagnose a fault. Once a fault has been identified an application may adapt by choosing an alternative service.[CD-JRA-1.1.4] | A fault could influence the non-functional
requirements |
||
| Service Infrastructure (KM-SI) |
A fault can be defined as a deviation in a quality of service in terms of
performance dimensions [CD-JRA-1.2.4]
[CD-JRA-2.3.4] |

| Generic (domain independent) |
A manifestation of an error in software. A fault,
if encountered, may cause a failure. [FOLDOC] Fault is an (usually) observable event in the service execution that can produce an erroneous state and, as a consequence, a failure. [CD-JRA-1.2.2] |
