Graceful Degradation

Also sometimes referred to as "Fault-Tolerant Degradation".

The property that enables a system or asset to continue operating properly in the event of the failure of some of its components

A measure of the degree of fault tolerance (robustness) of a system.

While operational quality does decrease during graceful degradation, the asset can continue to function above a minimum acceptable level.In other words, Potential Failure (P) has occurred, but Functional Failure (F) has not yet been reached.

Fault-tolerance will depend on the following factors:

Bounded assets are typically designed for graceful degradation or elegant degradation.
