In my mind, having individuals and small self managed teams go off and do whatever they feel drawn to do is exactly how a good company is run. - So long as those teams and individuals talk to (& seek advice) from the rest of the company when their work has impacts outside the team. The book Reinventing Organizations by Laloux talks about this a lot, and how it works in some companies today.

The reason it doesn't happen more is that upper management doesn't trust their employees and they don't feel in control when people just do things.
