In that air, the manual for the dedicated device and software that engineer use is awful unclear.

There is no attitude to have understood the contents, with malicious intentions.

Why does it happen?

The reason is that the developer of the product makes the manual.

They make the manuals to depend on the Pareto principle faithfully.

The explanation of 20% of functions that we never use, occupies 80% of the whole of manuals.

Besides, the developer cannot explain only the simplest usage, and she/he is going to list them without leaking all exception matters.

(For the developer, there is no help for trying to explain all of the function of the products.)

As a result, the manual not to make understand even simplest work is completed.

Why is it like that?

This is because there is little number of the users.

There is not tens of millions of user in the whole world. 。

For less than one hundred users in Japan, the cost of user's objections, become lower than making splendid manuals.

In addition, the manner of "you are an engineer, so you can do something by yourself" seems to be confirmed.

In conclusion, the manuals for the dedicated device and software that engineer use, becomes awful unclear.
