Every time you made a mistake, you were instructed by your boss to "think about countermeasures!" weren't you?
Then, like an excuse, you said, "I strengthen the check.".
If you are worried about making mistakes,
"I made a mistake because I was careless."
"At that time, if I was reviewing it again, I won't have made a mistake."
"If you check it many times, you will find the problem. It will not be leaked to the outside!"
You have thought so at that time.
"Double-check to prevent! Be careful after that!"
In the first place, you use "a process on the premise of making a mistake".
The unconscious affirms the mistake.
You are worried about when to sprout after sprinkling the seeds of mistakes. So please check again and again over time.
Though, wait a minute.
The act of checking does not change anything. It's a wasteful act. I want to get rid of it using as much wisdom as possible.
The idea of reducing the person-hours for checking by kaizen is essential. It's common thinking.
It's the idea of "cutting off the waste from the beginning!"
You usually make Double-check, triple-check, then check again.
The human brain does not work as expected.
Nothing happens for the first week or month because you are careful.
But time passed, you've forgotten that you made a mistake.
When you are busy, the unconscious dismisses the work you understand as common.
You just put a check on it, but you haven't checked it properly. So you haven't seen it exactly.
Because RAS(Reticular Activating System) works, it doesn't tell the brain that the unconscious doesn't think it's essential.
When the human brain makes a full rotation, it uses enormous energy.
The work of RAS is that defence.
The work of unconsciously moving your hand and skipping the check will be repeated automatically.
The unconscious moves in the same way that you breathe unconsciously.
You have not yet taken measures to eliminate mistakes.
No matter how many times you check, mistakes will go through the colander's holes, and you will mistake again.
If you say, "Ah! I made a mistake again. ", I can't forgive you just by checking anymore.
In such a case, go back to the original point and
It is essential to find the cause and eliminate it.
Process-oriented. If you can trace what kind of work you were doing,
There is always a seed of mistake in it.
In the case of the story above, raise abstraction by looking at things from above.
If you can find the root cause, your anxiety will disappear.
