I really counsel everyone to stop thinking like this. The appealing to authority doesn't work when you are talking about different sized businesses.
All the best banks and tech firms do a lot of things that could be categorized as wasteful, useless, inertia maintaining, etc, adopting their practices without a thorough understanding if it applies to your business is plainly just stupid.
Your business is not structured like those big business, you are not as anemic to risk as they are (otherwise you wouldn't even create your business in the first place), you don't have their cash, you don't have their ability to spend an enormous amount of time hiring every single person because your profits cushion you from all your dumb decisions.
