Is the only type of error a ‘human error’? I struggled to think of an ‘error’ that is not a human error, so we asked if others could think of something else. We thank Dr. Peter Elias, who commented that errors can occur in biologic processes, such as RNA and DNA replication or messaging. He also cited non-human animals making errors all the time as well.
For our purposes on this blog, we will focus on human error as being the most prevalent in our working environments. Step 1, we should define it so we all use the term consistently and appropriately. This helps us define the scope of the term. For this discussion, I will use Todd Conklin’s concise, and to the point, definition from Pre-Accident Investigations (Conklin, 2014, p.8), “An unexpected deviation from an expected outcome.”
Let’s run with that definition for now. From this, I will take the liberty of defining a ‘failure’ as an ‘unexpected outcome’. So unexpected deviations are eventually linked to human errors, which are simply errors of omission or commission in human decision-making. By our decisions, we create the propagation of future, observable pathways to either success or failure. Appropriate decisions trigger pathways to success and inappropriate decisions result in failures. Pretty simple in concept so far, right?
