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

Management of change points It is important to manage the 3Hs (first time, change, long time no see)!

Create a "procedure manual" to deal with defects or to promote multi-skilled workers ! said a voice.
An organization that can be said to have no procedure manual (procedures) at all
, or an organization that has it but wants to improve it
Hmm, I know what you're talking about
Now, when I try to maintain it, I will involuntarily flinch against the huge number of product numbers.
However, at times like this, if you calm down and think about it,
First,
a) A product that is normally in circulation
b) A product that is manufactured several times in a few months
c) A product that has not been manufactured at all for the past few years
and so on.
For a large number of product numbers,
Now, realistically, when and from what should we create it? ?
A certain company faced with such a situation concluded that it should be created step by step based on the following concept.

Consider the procedure manual (procedures) based on the 3Hs (first time, change, long time no see) concept.

First time, Change, Long time
no see ( often referred to as 3H )
Products that are manufactured on a daily basis are postponed.

① First time

For each new product, a procedure manual is created before manufacturing or together with manufacturing.

☆ even for the first time
There are "completely new products" and "products with high similarity to the past," even if it is the first time.
When it comes to a completely new product, you will have to design each process/work carefully without any help or effort.
However, when it comes to products with high similarity,
It's not uncommon for people to say, "No, that's wrong!"
Not only for new products, but also for highly similar products, let's create a detailed procedure manual (procedures) carefully.
