- | Then a failure remains undetected, it propagates through the system ultimately causing other modules to fail. This results in in a more complicated fault removal. Furthermore undesired side effects like corrupted files may occur. A crashed program clearly communicates that there is a problem and is often a better situation than a misbehaving program. | + | When a failure remains undetected, it propagates through the system ultimately causing other modules to fail.

- | See section [[#contrary principles]]. | + | FF reveals problems which are already present in the system. For a system with only a few problems, this is good as the remaining faults are identified and fixed more easily. But applying FF to a system that has many problems may decrease reliability further as problems which were hidden, show up, produce error messages and lead to system aborts. |
