Basic System Outage Principles
A system fault can be caused by internal or external factors. Examples of internal factors could include specification or design errors, manufacturing defects, component defects, and component wear-out. Examples of external factors could include radiation, electromagnetic interference, operator error, and natural disasters.
Regardless of how well a system is designed, or how reliable the components are, failures cannot be eliminated completely. However, it is possible to manage failures and thereby minimize impact to the system.
