"High reliability can be achieved in a product without having high reliability in the component parts. In fact, any reliability target, no matter how high, can be achieved with only mediocre parts, so long as enough of them are present." Discuss; an example may help.
High Reliability
Refers to systems or organizations that operate in conditions where the cost of failure is high, focusing on safety and minimizing errors.
Component Parts
Individual items or pieces that, when assembled, make up a finished product or are integral to its operation.
Mediocre Parts
Components or elements of a system that are of average or slightly below average quality, possibly affecting the overall performance.
- Understand the concept of product reliability and its determinants.
- Understand the role of redundancy and component quality in achieving high system reliability.

Final Answer :
This carries the redundancy concept one step beyond the textbook, to having multiple redundancies on the same component. If only one part in a parallel system needs to work to provide reliability of that part of the system, then several parts in parallel should offer very high reliability. Example: four parts in parallel, each with only 0.50 reliability, provide reliability of .50 + .25 + .125 + .0625 = .9375. Additional parts in parallel continue to improve reliability.
