Предотвратите человеческие ошибки, управляя точками изменения, такими как управление изменениями 4M и управление 3H

Prevent quality deterioration due to human error by combining 3H x 4M

I think that there are many people who are troubled by "assuming" and "careless mistakes", commonly called "human error". The trouble with human error is that it will not go away as long as humans are working.
Nonetheless, measures against human error must be taken. If left unattended, the quality will only deteriorate. As I mentioned at the beginning, it is impossible to eliminate human error, but from the perspective of "3H x 4M", it is possible to have a certain degree of accuracy and take effective countermeasures.


■ 3Hs of human error
The 3Hs of human error simply express the situations in which humans are prone to make mistakes and failures when working. Many human errors are triggered by these 3Hs.
First time: Hajimete
Change: Henkou
Long time no see: Hisashiburi
"First time" means the first time you perform a task.
“Modification” means work for which the work procedure or method of execution has been changed.
“Long time no see” is a task that is performed for the first time in a long time.
In other words, if we take preventive measures against these 3Hs, human error can be reduced, but "for what" is important. That is the 4M of quality control.
■ 4M of quality control
The 4Ms of quality control are elements for implementing quality control, and when quality troubles occur, it is thought that something is wrong with these.
Person: Mam
Equipment: Machine
Material: Material
Method: Method
When viewed as an individual, "person" means skills, experience, and so on. When viewed as an organization, it also includes human relationships.
“Equipment” refers to machines used to make things.
“Materials” are materials used to make things.
A " method" is a way of working.
In other words, if we take preventative measures from the perspective of 3H against 4M, we can prevent quality deterioration due to human error.
■ Clarify the perspective of human error with 3H x 4M
If you create a 3H x 4M matrix based on the above, you can see things that are likely to cause human error.

Below is an example that I have filled in.

What do you think? Some people may be revived by past painful experiences. In my experience, there was a case where I didn't notice that the procedure manual had been changed, and I worked with the assumption that I remembered the old procedure manual.
In this way, by combining 3H and 4M, we can see the points to prevent human error. I am practicing this, and comparing before and after, I think I have become able to prevent it with a fairly high probability.
When human error occurs, analysis and countermeasures become difficult. I don't think it takes much effort to create the above matrix, so let's make project management easier by focusing on preventive activities.
