Fixing culture is the most critical − and the most difficult − part of a corporate transformation… In the end, management doesn’t change culture. Management invites the workforce itself to change the culture.

Until I came to IBM, I probably would have told you that culture was just one among several important elements in any organization's makeup and success - along with vision, strategy, marketing, financials, and the like... I came to see, in my time at IBM, that culture isn't just one aspect of the game, it is the game. In the end, an organization is nothing more than the collective capacity of its people to create value.

The next thing is: we can make IBM even better. We brought IBM back but we're gunning for leadership.

I don't want to use the word reorganization. Reorganization to me is shuffling boxes, moving boxes around. Transformation means that you're really fundamentally changing the way the organization thinks, the way it responds, the way it leads. It's a lot more than just playing with boxes.

Vision is easy. It's so easy to just point to the bleachers and say I'm going to hit one over there. What's hard is saying, OK, how do I do that? What are the specific programs, what are the commitments, what are the resources, what are the processes we need in play to go implement the vision, turn it into a working model that people follow every day in the enterprise. That's hard work.

We built this company from the customer back, not from the company out.

It is not about bits, bytes and protocols, but profits, losses and margins.
