He said the basic research unit was not affordable and needed to be downsized. He was quite concerned about IBM’s software business, mainframe business, and midrange products. As I look back at my notes, it is clear he understood most, if not all, of the business issues we tackled over the ensuing years. What’s striking from my notes is the absence of any mention of culture, teamwork, customers, or leadership—the elements that turned

out to be the toughest challenges at IBM…

I went home with a deepening sense of fear. Could I pull this off? Who was going to help me?

Now, I must tell you, I am not sure that in 1993 I or anyone else would have started out to create an IBM. But, given IBM’s scale and broad-based capabilities, and the trajectories of the information technology industry, it would have been insane to destroy its unique competitive advantage and turn IBM into a group of individual component suppliers—more minnows in an ocean.

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.

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.
