Yet behind I.B.M.’s relentless progress over the last decade is a game plan that has been anything but conservative. The company shed multibillion-dollar businesses. It chose higher profit margins over corporate size, and expanded aggressively overseas, seeking sales, low-cost engineering talent and quicker organizational reflexes.

Investors, however, haven’t been bored. The company’s stock price has surged. In November, Warren E. Buffett, who typically shuns technology stocks, announced he had accumulated $10 billion of I.B.M. shares, a stake of more than 5 percent.

All of that didn’t just happen. A large portion of the credit goes to Samuel J. Palmisano, who steps down on Sunday after nearly a decade as chief executive. During his tenure, I.B.M. has been a textbook case of how to drive change in a big company — when so much of the study of business innovation focuses on start-ups and entrepreneurs.

This column is a glimpse of the thinking behind some of the major steps I.B.M. has taken under Mr. Palmisano’s leadership, based on two recent interviews with him.

He says his guiding framework boils down to four questions:

• “Why would someone spend their money with you — so what is unique about you?”

• “Why would somebody work for you?”

• “Why would society allow you to operate in their defined geography — their country?”

• “And why would somebody invest their money with you?”

Mr. Palmisano formulated those questions in the months after he became C.E.O. in March 2002 His predecessor, Louis V. Gerstner Jr., recruited to I.B.M. in 1993, had already pulled the company out of a financial tailspin, first reducing the size of the work force and cutting costs, and then leading a remarkable recovery.

In meetings after he took over, Mr. Palmisano told colleagues that I.B.M. was still good, but that it wasn’t the standard-setting corporation that it had been when he joined in 1973. (A history major at Johns Hopkins and a star offensive lineman on the football team, he turned down a tryout with the Oakland Raiders of the N.F.L. for a sales job at the company.)

The four questions, he explains, were a way to focus thinking and prod the company beyond its comfort zone and to make I.B.M. pre-eminent again. He presented the four-question framework to the company’s top 300 managers at a meeting in early 2003 in Boca Raton, Fla.

“This needs to be our mission and goal, to make I.B.M. a great company,” he said, according to executives who attended the gathering.

THE pursuit of excellence in those four dimensions shaped the strategy. To focus on doing unique work, with its higher profits, meant getting out of low-margin businesses that were fading. I.B.M.’s long-range technology assessment in 2002 concluded that the personal computer business would no longer present much opportunity for innovation, at least not in the corporate market.

The hub of innovation would shift to services and software, often delivered over the Internet from data centers, connecting to all kinds of devices, including PCs. Today, that is called cloud computing; when I.B.M. started promoting the concept several years ago the company called it on-demand computing.

So Mr. Palmisano led a lengthy strategic review of the PC business, deciding to sell while it was still profitable. Internal arguments against a sell-off were intense: PCs pulled in sales of other I.B.M. products in corporate accounts, the cost of electronic parts for its larger computers would jump without the purchasing power of its big PC division, and the corporate brand and its reputation would suffer without PCs, the one I.B.M. product touched by millions of people.

Lately, Hewlett-Packard has engaged in a similar debate, first declaring that it was looking to sell its PC business, then backing off. “I’ve heard every one of the arguments, every one of them,” Mr. Palmisano says. “But if you decide you’re going to move to a different space, where there’s innovation and therefore you can do unique things and get some premium for that, the PC business wasn’t going to be it.”
