Abstract : THE FACT THAT A FAILURE HAS OCCURRED, USUALLY CAN BE DETECTED WITHOUT A SPECIFICALLY-DESIGNED FAILURE INDICATOR. IN A COMPLEX DEVICE, HOWEVER, MANY TYPES OF FAILURE INDICATORS CAN BE HELPFUL IN DETERMINING THE SOURCE OF TROUBLE. IF RELIABILITY IS DEFINED TO BE A MEASURE OF THE PERCENTAGE OF TIME A DEVICE IS OPERABLE, THEN PROPER DESIGN AND USE OF FAILURE INDICATORS CAN IMPROVE RELIABILITY. THE RELATIONSHIP ISSHOWN BETWEEN THE STATISTICAL THEORY OF FAILURE INDICATORS AND OTHER PARTS OF THE RELIABILITY LITERATURE AND DEVELOPS SOME OF THE PRINCIPLES WHICH SHOULD BE FOLLOWED IN THE DESIGN AND USE OF FAILURE INDICATORS. AS MIGHT BE EXPECTED, A NUMBER OF THESE PRINCIPLES WERE FOLLOWED BY GOOD MAINTENANCE MEN FOR MANY YEARS
