IBM Under Gerstner
Featuring Lou Gerstner
In 1993, IBM posted roughly $8 billion in losses, the largest single-year corporate loss in American history to that point. Wall Street's prescription was amputation: break the lumbering giant into focused pieces and let the parts find their own value. The board was ready. Then Lou Gerstner, a newcomer with no technology background, arrived from American Express and RJR Nabisco, spent his first months listening to IBM's biggest customers, and heard something that pointed the opposite way.
This is a case about asking what business you are actually in, and the discipline to act on an answer that contradicts both the analysts and your own history. For founders and operators, it sharpens the gap between what you think you sell and what customers actually hire you to do, and what it costs to let go of the thing that once made you great.

How big was IBM's loss in 1993?
IBM posted roughly $8 billion in losses in 1993, the largest single-year corporate loss in American history to that point. Wall Street's prescription was to break the company into pieces. Lou Gerstner arrived that year and chose to keep IBM together instead.
Why did Gerstner decide not to break up IBM?
Gerstner decided to keep IBM whole after listening to its biggest customers, who valued an integrated provider that could solve their problems end to end rather than a set of focused parts. He realized IBM's real business was solving customer problems through services and systems integration, not just selling hardware. That insight contradicted both the analysts and IBM's own history.
What can operators learn from IBM's turnaround under Gerstner?
The lesson is to ask what business you are actually in by understanding what customers truly hire you to do, even when the answer contradicts analysts and your own history.
