Gilb's Laws of Unreliability
1) Computers are unreliable, but humans are even more
unreliable.
Corollary: At the source of every error which is
blamed on the computer you will find at least two
human errors, including the error of blaming it on
the computer.
2) Any system which depends on human reliability is
unreliable.
3) The only difference between the fool and the
criminal who attacks a system is that the fool
attacks unpredictably and on a broader front.
7) Undetectable errors are infinite in variety, in
contrast to detectable errors, which by definition
are limited.
9) Investment in reliability will increase until it
exceeds the probable cost of errors, or until
someone insists on getting some useful work done.
