How can we reduce error?
Five ways to reduce errors based on reliability science
- Standardize your approach.
- Use decision aids and reminders.
- Take advantage of pre-existing habits and patterns.
- Make the desired action the default, rather than the exception.
- Create redundancy.
Is human error natural?
The propensity for error is so intrinsic to human behavior and activity that scientifically it is best considered as inherently biologic, since faultless performance and error result from the same mental process. All the available evidence clearly indicates that human errors are random unintended events.
What is error prevention?
What is ‘error prevention? ‘ ISO 25000 describes the ‘error prevention’ as ‘degree to which a system protects users against making errors. ‘ 1 In other words, designing a system in a way that it would try to make it hard for the user to commit the error.
Why is error prevention important?
Essentially, it involves alerting a user when they’re making an error, with the intention to make it easy for them to do whatever it is they are doing without making a mistake. The main reason this principle of error prevention is important is that we humans are prone to- and will always make mistakes.

There are many types of human error, which have just as many causes. After all, 90% of accidents in the workplace are due to human error. Because of this, it’s important to recognize the common causes of human error to prevent those errors from becoming accidents.
What are four factors that frequently contribute to human error?
Human factors: Managing human failures
- Significant potential human errors are identified,
- Those factors that make errors more or less likely are identified (such as poor design, distraction, time pressure, workload, competence, morale, noise levels and communication systems) – Performance Influencing Factors (PIFs)
Why is human error important?
Human error is an important consideration in complex safety critical systems, because it makes the most significant contribution to overall system risk (Edwards, 1988). The goal of a HF assessment is to make systems successful by enhancing performance, satisfaction and safety.
