MBTI

By now, just about everyone has a Myers-Briggs profile, and probably a whole lot of other profiles too. We've learnt that not only are other people different but that other people's styles can complement our own - round out the square bits in our own personality giving the team a smoother ride.
But how does this affect how we communicate with people (and I'm thinking particularly about the difficult interface between front-line care professionals and managers/ strategists/ budget holders)?
Sould you like a sure-fire way of both understanding, and being understood, by "the other side"?
