Human errors Flashcards
(10 cards)
What are the categories of human performance that can lead to errors, defined by James Reason?
- skills-based performance
- Rules-based performance
- Knowledge-based performance
What are the types of errors in the generic error modelling system?
- Slips
- Lapses
- Mistakes
What is the definition of slips?
the user’s intentions are correct but actions aren’t carried out properly
What is the definition of lapses?
Forgetting to perform an action
What is the definition of mistakes?
the wrong set of actions are executed due to poor reasoning
What re the advantages of the generic error modelling system?
provides a structured framework for designing systems that minimises human errors
What are the limitations of the generic error modelling system?
- focuses on non-deliberate errors and overlooks deliberate actions (like taking shortcuts)
- Neglects contextual factors
What are the challenges with addressing human error?
- Humans are inherently fallible
- Human behaviour varies significantly
- Emphasises error tolerance over error avoidance
How can you plan for errors?
- Increase system visibility
- include errors in training
- Design user-centred interfaces
- Design for errors
Why can automation not be the solution to preventing errors?
- Only solves rule-based and skill-based tasks - knowledge-based tasks requires humans
- Processes will be less visible to users, making it harder to troubleshoot
-Automation can lead to larger design flaws instead of simple human flaws
