The author calls it "organizational health." I prefer to think of it as an authentic organization. Health gives the impression that it's a matter of following a regiment of good habits. Whereas authentic implies that it has to come from within the individuals. The book applies to leaders of an organization, not so much to workers. If you're not a manager, you would not even get to practice the first discipline of building a cohesive team (build trust, work through conflicts, commit to decisions, be accountable, and focus on results). The other three disciplines really need to come the top leadership of the organization - create clarity in purpose and direction of the organization, over communicate that message, and reinforce that message.
