Sorry if this gets posted a lot later than usual. I need to laugh my head off.
Anywho, you're totally right. You need a superviser. But this superviser doesn't need to be good at everything, just have a basic understanding of them. If I see someone do something obviously wrong, I can step in and point it out for them. Also, can people not be their own supervisor? They are really good at their one thing, so can they not make sure their part of their product is of quality? You seem to think that in order for a quality product to be made, a woman must be apart of the designing process, which is not only demonstrably false and sexist, but makes no sense. Mojang, which was a group of four men who made the great computer game minecart, never even came in contact with a women through the design process. They also had no supervisor, BTW. My arguements aren't false because they come from a field you don't understand. Just like I can't ditch anything scientific because I don't understand it. That would be a logical fallacy! If you need more examples, try almost every business on shark tank ever.
