You can’t mandate [cultural change], can’t engineer it. What you can do is create the conditions for transformation. You can provide incentives. You can define the marketplace realities and goals. But then you have to trust. In fact, in the end, management doesn’t change culture. Management invites the workforce itself to change the culture.

I look for people who work to solve problems and help colleagues, I sack politicians.

The thing I have learned at IBM is that culture is everything.

Everything starts with the customer.

I have always believed you cannot run a successful enterprise from behind a desk.

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

You can never be comfortable with your success, you've got to be paranoid you're going to lose it.
