I read this great article "the February Revolution" listing four things that tend to happen when great results are achieved. The thing that interested me the most was how similar at least three of the items were to how a successful military unit operates.
Though listed last, the everyone cares is the most important point of all these. If everyone cares that is probably enough to achieve great things. But it is also the most difficult one to achieve since it relies on each individual to actually care... In my experience I've seen that if the leaders (formal and informal) of a group cares and show that they care, the rest of the group typically start to care pretty quickly too. This takes the form of both taking action but also rewarding the team for caring.
