Mr. Covey explains in his book, “The 7 Habits of Highly Effective People,” that synergy means the sum is greater than all of its parts. Another way of thinking of synergy, which might help clarify things, is to consider how nature works. The basic components for life are in place at its foundation. But, as time progresses, (sometimes quickly and other times not so quickly) it evolves to be greater/larger than what the original components could have produced in theory/on paper.
Mr. Covey explains to us, too, that it is the differences in people that can create synergy in a group. So long as there is a high level of maturity in the group a tremendous amount of synergy can take place, which results in great things being accomplished. This accomplishment is usually far greater than the wildest dreams and fantasies of every person involved in this synergistic process.
Stephen writes that synergy is a celebration of differences and the combination of these things, which makes the sum of the whole far greater than each and every one of its parts.
