yeah but on the other hand, even though you don't know the "why", it still exists.
I understand the dilema, but training makes sence, you just don't always know why. It's important for us to know why, but not neccesary and sometimes even that won't satisfy you.
Now I have examples of things that worked fine but were changed, and the resulting change created huge costs in manhours and maintenance, but management did it anyways. Then started complaining about manhours and productivity... when the new policy was the cause.
Where I work has litterally hundreds of these examples.
We used to be a family owned/operateed business, and now owned by a Dutch holding firm. They have no idea what they are doing, and the business is slowly going downhill.
