I like this point but can you elaborate on it more? My knee jerk reaction is to say "why". I'm not very familiar with manufacturing as I'm sure a lot of people aren't, but it seems like most of the knowledge is in the design of the factory not in the skill of the workers. I know that might be an ignorant statement but that's why I'm asking for elaboration.
