Which are the main error classifications commonly cited in human factors?

• A. Omission, commission, substitution, slips/lapses, and mistakes
• B. Planning errors, miscommunication, delays, and fatigue
• C. Negligence, malpractice, recklessness, and error
• D. Natural variance, random events, and inevitability

Answer: (A)

In human factors, errors are typically categorized into execution errors and planning errors. The list of omissions and commissions covers actions not taken or taken incorrectly during performance, while substitution refers to replacing the intended action with a different one. Slips and lapses are execution failures caused by momentary attention or memory breakdowns—getting distracted, misreading a cue, or forgetting a step. Mistakes encompass flawed planning or decision-making, where the chosen plan or rule is inappropriate for the situation. This combination is widely used because it helps identify where a breakdown occurs and guides how to reduce risk—whether by improving procedures, training, or interfaces to support correct action. The other options describe factors, conditions, or non-standard legal labels rather than the standard error classifications used in human factors.
