Highlight from 'Managing Transitions' by William Bridges, Susan Bridges

To deal successfully with transition, you need to determine precisely what changes in their existing behavior and attitudes people will have to make. It isn’t enough to tell them that they have to work as a team. They need to know how teamwork differs behaviorally and attitudinally from the way they are working now. What must they stop doing? And what are they going to have to start doing? Be specific. Until these changes are spelled out, people won’t be able to understand what you tell them.
