ABSTRACT
Let us begin with a thought experiment. Think for a moment about one of the finest groups you have ever seen-one that accomplished its work superbly, that got better and better as a performing unit over time, and whose members came away from the group experience wiser and more skilled than they were before. Next, think about a different group, one that failed to achieve its purposes, that deteriorated in performance capability over time, and whose members found the group experience far more frustrating than fulfilling.
