This is good.  For me, production of the whole operation was placed on the shoulders of one team.  Yes they were a key piece, but as it turned out, once they improved (mainly through overcoming negativity) - there was no big hurrah.  Why is that?  Blame shifting, the others needed an excuse.  I don't recall reading any book or even calculating what to do.  I simply started working with them, and did what seemed the  obvious fixes.  They literally believed what was being fed to them, the negative info.  No one can be effective that way.  It was a relatively short turn around time for them, so I didn't even think much about it, didn't feel I did much.  Much later I realized, what that did for the individuals and how it turned the heat elsewhere, why there was no hurrah, to fix bigger problems.  Sometimes all that's required is for you to show up and do what seems obvious, it still counts.
