Managers schedule meetings so that developers can’t get anything done. Then they hire more developers, which means even more meetings. Virtuous cycle!

Good managers are like firewalls: they shield from negative outside influences and let good or important information and tasks pass.

That includes representing department in stupid meetings, instead of wasting developers/engineers time.

Insulating developers from the rest of the business or other engineering teams is a hallmark of a poor manager, not a great one.

Kelly Johnson would disagree, and his management style is taught around the world.
