There's another lesson here as captured by the Harvard Business Review. Let's suppose you're a technology organization, especially an IT organization, and you want greater innovation. What path should you take? Should you focus on innovation or should you focus on execution? Counterintuitively, those organizations focusing on execution achieved greater innovation than those focusing on innovation. Execution is everything. Why do so many of us have all these great ideas yet aren't millionaires? Execution. So Tim Cook is focused on execution. Good.
