Hello Geoff,
Another link in the same vein:
Reliability Centred Maintenance (RCM)
After being created by the commercial aviation industry, RCM was adopted by the U.S. military (beginning in the mid-1970s) and by the U.S. commercial nuclear power industry (in the 1980s). It began to enter other commercial industries and fields in the early 1990s.
