It’s a very simple, two-by-two matrix in which you have four zones: the efficiency zone, where you put all your noncore activities that you need to be really efficient; your performance zone, which is your core business—that’s 80 percent of what you do, and it’s all about execution. But you need to never forget the two other quadrants: the innovation zone—that’s your lab. It should never have more than one or two things you want to try. Then you have the transformation zone, where you put one or two things that in two years will become the performance zone. Every company needs to nurture those four quadrants at the same time, not focus on just one.
