On the other hand, if pump C fails while pump B is still
working (for instance if someone cannibalises a part from
C), it is likely that the operators will not even know that
C has failed unless or until B also fails. To guard against
this possibility, a sensible maintenance strategy might be
to run C from time to time to find out whether it has failed.
This example shows how three identical assets can
have three totally different maintenance policies, because
the failure consequences are different in each case.
• maintenance tasks: different organisations – or even different parts of the same organisation – seldom employ
people with identical skillsets. This means that people
working on one asset may prefer to use one type of proactive technology (say high-tech condition monitoring) to
anticipate failure, while another group working on an
