What the quoted paragraph doesn't show is the hiring process, "servant leaders" will only work if you hired the right candidates and provided initial guidance on expectations. Right candidates for the job at hand is _the_ hardest part.
My current workplace hired junior level developers who came through with very limited coding skill and but talked their way into permanent positions. They quickly hired consultants to "help" them with projects, and settled to become requirement gatherers and use the consultants to code all their stuff.
My point is, if you were to walk in as new manager in your group, kicking butt and firing people, and NOT be a servant leader, might work better.
