This chapter explains the sixth habit of effective people—synergy. Covey believes that synergy is the culmination of the habits taught in previous chapters because it combines oppositional elements in a way that leads to a constructive outcome. The whole becomes greater than the sum of its parts. He says, “Synergy […] catalyzes, unifies, and unleashes the greatest powers within people. All the habits we have covered prepare us to create the miracle of synergy” (308).

The author goes on to give examples of synergistic communication in both classroom and business settings. In each instance, one courageous individual speaks to the rest of the group about deeply held emotions or beliefs. These act as a catalyst to stimulate others to share their personal experiences and concerns. This spontaneous sharing leads to conclusions that none of the individuals might have struck upon independently. “Once people have experienced real synergy, they are never quite the same again. They know the possibility of having other such mind-expanding adventures in the future” (315).

A key element in creating synergistic solutions is to develop a sense of trust among those communicating with one another. Cooperation only becomes possible if the atmosphere isn’t fraught with hostility and fear.
