Reliability promotes failures. Failures promote reliability When a system is reliable long enough, production pressure causes the operators to drive the system harder; Over time operators become less careful as the trauma of the last failure wears off. More workload is applied, new features introduced, etc, until the system trails again into the danger zone (e.g. high load once thought to be dangerous), sailing through smoothly this time, thus boosting the confidence of operators in the robus...
