Reliability

Definition and stakes

Edmund Callis Berkeley,  Giant brains; or, Machines that think (1949)

“ NEW IDEAS IN RELIABILITY
Reliability has a number of aspects:
1. No wrong results allowed out of the machine. 2. Few failures. 3. Rapid location of failures. 4. Quick repair or replacement of parts that fail. 5. Easy maintenance. 6. Unattended operation overnight. For example, Bell Laboratories proved that mechanical brains can be built so that no wrong results are allowed to come out. In other words, the machine checks itself all the time as it goes along and stops at once if the check shows that something is wrong.

“ These are personal hygiene, selection of healthy mates, and the betterment of the environment.
Personal Hygiene.—In the first place, good health is the one greatest asset in life. We may be born with a poor bodily machine, but if we learn to recognize its defects and care for it properly, we may make it do its required work effectively. If certain muscles are poorly developed, then by proper exercise we may make them stronger. If our eyes have some defect, we can have it remedied by wearing glasses. If certain drugs or alcohol lower the efficiency of the machine, we can avoid their use.
