Principle
11. Cushion in Advance
a. Compensate for the relatively low reliability of an object by
countermeasures
taken in advance
- Principle Description: Prepare in advance — and understand nothing is perfectly reliable.
- Hints on Usage: Acknowledge the fact that nothing is perfect.
In many cases, a system’s reliability is manageable. With complex or high-volume systems, however, there is a likelihood of unacceptable failures. If these failures cannot be totally eliminated, it is important to prepare or compensate for the lack of reliability. Also, prepare in advance for situations with a high risk or high cost of failure.
