The
supervision
of technical processes and the
quality control
of products is aimed at showing the present state (
condition monitoring
), indicating undesired or unpermitted states, and taking appropriate actions to avoid damage or accidents. The deviations from normal process behavior result from
faults and errors
, which can be attributed to many causes. They may result sooner or later in malfunctions or failures if no counteractions are taken. One reason for supervision and quality control is to avoid these malfunctions or failures.
