"There is, however, a lesser-known piece to this story. As Christensen recalls, Grove asked him during a break in this meeting, "How do I do this?" Christensen responded with a discussion of business strategy, explaining how Grove could set up a new business unit and so on. Grove cut him off with a gruff reply: "You are such a naive academic. I asked you how to do it, and you told me what I should do. I know what I need to do. I just don't know how to do it." As Christensen later explained, this division between what and how is crucial but is overlooked in the professional world. It's often straightforward to identify a strategy needed to achieve a goal, but what trips up companies is figuring out how to execute the strategy once identified."
