The discussion that ensued was very sobering. IBM’s sales and profits were declining at an alarming rate. More important, its cash position was getting scary.

However, what was also clear was that IBM was paralyzed, unable to act on any predictions, and there were no easy solutions to its problems. The IBM organization, so full of brilliant, insightful people, would have loved to receive a bold recipe for success—the more sophisticated, the more complicated the recipe, the better everyone would have liked it.

It wasn’t going to work that way. The real issue was going out and making things happen every day in the marketplace.

I think it would have been absolutely naïve—as well as dangerous—if I had come into a company as complex as IBM with a plan to import a band of outsiders somehow magically to run the place better than the people who were there in the first place. I’ve entered other companies from the outside, and based on my experience, you might be able to pull that off at a small company in a relatively simple industry and under optimal conditions.

I have worked in services companies (McKinsey and American Express) and product companies (RJR Nabisco and IBM). I will state unequivocally that services businesses are much more difficult to manage.

This kind of wrenching cultural change doesn’t happen by executive fiat. As I found, I couldn’t flip a switch and alter behaviors. It was, by any measure, the hardest part of IBM’s transformation, and at times I thought it couldn’t be done.
