Well, actually as far as I have observed no matter what happens on the top the real people doing the real job (HW&SW design when looking from my viewpoint) are going to carry on as usual.

Only way the top leadership can affect the inner workings of a company is to fire&hire whole departments, otherwice the train rolls on just like before, some tags and labels change on the middle management but the real work continues just like before.

It is an illusion that management could somehow direct the company, all they can do is present an external image
