"The life of business models is declining. They don’t last as long as they used to. In the old days CEOs and other leaders of organizations didn’t have to change their business models. They could run their entire careers and spend their entire time focused on how to improve performance. Today the business models don’t last as long so the real challenge for a twenty-first century leader is how to improve the performance of the current business model while at the same time beginning to envision, design, prototype and test entirely new business models. This even includes those that might disrupt the existing one. It’s hard to do, but if you’re not thinking this way you’re going to be more and more vulnerable to being disrupted."
