Heterogeneous teams outperform homogeneous teams, fact.
A driver is the only club to have... as long as you are playing a long straight fairway with no complications. But a driver won't get you out of a bunker, and a sand wedge is no good to you if you are stuck in the long grass. The best golfers know they need a driver, some irons, a sand wedge, putter, and woods. And so it is with teams; real diversity in teams creates a more rounded approach to the challenges of the 21st century, freeing up a range of different perspectives to solve problems, innovate for the future and drive good business.
