Error/Slip > (Specification-Issue) > Specification-Defect > Fault/Bug/System Defect > Malfunction
1. Errors are usually committed unintentionally; they are often forced to happen by “bad” Work-Processes (Statistical-Process-Control Theory [DEMING86, JURAN64 &74]).
2. Human errors in specification Processes lead to Defects in specification or evaluations.
Saying, and similar to Plutarch (A.D. 46-120) “For to err in opinion, though it be not part of wise men, is at least human.”
