Failure

With this definition we try to capture the common concept of failure present in the literature: the loss of the ability to perform a function. We also stipulate, by definition, that failures cause faults. For example, if a wire, whose function is to carry electricity, is gnawed by a rat, the wire fails when it breaks and ceases to be able to conduct electricity.
