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.

The implications of this kind of leap to a company’s economic model can be devastating. In IBM’s case it meant the collapse of gross profit margins and the attendant changes we had to engineer to lower our cost structure without compromising our effectiveness.

Yet the hardest part of these decisions was neither the technological nor economic transformations required. It was changing the culture—the mindset and instincts of hundreds of thousands of people who had grown up in an undeniably successful company, but one that had for decades been immune to normal competitive and economic forces.

I suspect that many successful companies that have fallen on hard times in the past—including IBM, Sears, General Motors, Kodak, Xerox, and many others—saw perhaps quite clearly the changes in their environment. They were probably able to conceptualize and articulate the need for change and perhaps even develop strategies for it. What I think hurt the most was their inability to change highly structured, sophisticated cultures that had been born in a different world.
