                              Figure 9 - OC Task Interval Example
       Inconsistent p-f intervals
       As previously stated, one of the criteria for selecting OC maintenance is that the p-f interval be
       consistent. That means that for all assets of a given type, the p-f is the same. In truth, that’s highly
       unlikely and variation is to be expected - within reason.
       If there is too much variation then it may not be possible to recommend an OC task for the failure
       mode being analysed but, if the variation is close enough to be a trend then the interval should be
       based on the shortest p-f interval.
