Be very generous with credit. But the same does not hold true with blame. As a manager, you'll have to accept responsibility for those experiments that don't work but be free with the credit when they do work. Understanding your organization is next. Look at what your purpose is, look at what your goals are, and allow change to happen in order for those things to be accomplished.
T is for Timing.
Don't wait until the horse is dead to get off. Try and foresee something happening a little bit earlier than that, perhaps when he is limping, it is a good time to get down and see what's wrong. There are actually three times in the life of a business for example when change is normally acceptable. First is the honeymoon stage when everything is new and exciting. Second is the crisis stage when it is too late to make good change and the third stage is the climate of change.
