One of the reasons why most "big ideas" go nowhere is because the idea originators do not have a team of collaborators on board to help develop and execute their ideas. Bottom line, it's easier to conceive than it is to deliver the baby.
Employees perform at different levels, when on different teams, in different situations with different people. Why do so many leaders spend so little time looking for synergies on their teams and so much time looking at individual performance?
Why am I so optimistic? Because of the wide assortment of technologies that are advancing at exponential rates and converging. They are enabling small teams to do what was once only possible for governments and large corporations.
Synergy is not some magical device that causes extraordinary results when people work together. It is behavior of whole systems that cannot be predicted by behavior of the individual parts of that system when observed separately.
