Re: Nonconformances and defects - Operator error, system, or both?
Most of our defects result from system.
So we should improve step by step

Okay - let me propose this logic flow:
1) All humans are fallible.
2) Systems are designed by humans.
3) Systems are fallible.
(We could discuss the proposal that, theologically, there was one infallible human - but I'm not going there...)
In Deming's equation, the person cannot be separated from the system - therefore, you cannot blame the person as a root cause of a non-conformance. However, all systems are inherently flawed because they are designed by humans --
So, my root cause is always human error.
My corrective action - remove all humans.
Let's see how much work gets done now...
Aren't these exercises fun?
Don't blame the operator. Just find out why interpretations or handling went wrong. In most of the cases it is psychologically defined. The 80/20 rule counts (80% operator!)
What? Please give us some details about this.Don't blame the operator. Just find out why interpretations or handling went wrong. In most of the cases it is psychologically defined. The 80/20 rule counts (80% operator!)
