Human Error Quotes

“Error is intimately bound up with the notion of intention. The term ‘error’ can only be meaningfully applied to planned actions that fail to achieve their desired consequences without the intervention of some chance or unforeseeable agency. Two basic error types were identified: slips (and lapses), where the actions do not go according to plan, and mistakes, where the plan itself is inadequate to achieve its objectives.”
― James Reason, Human Error
