No Fault Found or NFF is not new. Strangely, no consensus exists as to it's causes or cures. Before ANY problem can be resolved it needs to be fully understood. To understand it, we need to define some terms so we can communicate. NFF has many aliases.
Every organization has it's pet name for it and associated database to track it.
Some break it down into sub-categories, confusing the issues even more. The equipment is more integrated and complex. The environmental abuses are worse. The margin for error is less. The NFF monetary and political impact is greater.
