Systematic failure

A failure that happens in a deterministic (non random) predictable fashion from a certain cause, which can only be eliminated by a modification of the design or of the manufacturing process, operational procedures, documentation, or other relevant factors. Since these are not mathematically predictable, the safety lifecycle includes a large number of procedures to prevent them from occurring. The procedures are more rigorous for higher safety integrity level systems and components. Such failures cannot be prevented with simple redundancy.
