How one chooses depends on one's understanding of what kinds of behaviors are desirable and sought, on the one other hand, and how they are likely to be elicited in the organization's environment, on the other hand. If, for example, you think that Machiavelli understood the realities of modern educational organizations, then his advice on leadership will be appealing and appear practical. If, on the other hand, you think that schools are best understood as bureaucracies, then you will do your best to create a bureaucratic environment for people to work in.
