the mechanism of a Fault-Error-Chain is understood it is possible to construct means to break these chains and thereby increase the dependability of a system.Four means have been identified so far:
# Prevention
# Removal
# Forecasting
# Tolerance

Fault Prevention deals with preventing faults being introduced into a system. This can be accomplished by use of development methodologies and good implementation techniques.

Fault Removal can be sub-divided into two sub-categories: Removal During Development and Removal
