Execution without excuses. Interview by Thomas A. Stewart and Louise O'Brien

The success of Dell--it provides extraordinary rewards to shareholders, it can turn on a dime, and it has demonstrated impeccable timing in entering new markets--is based on more than its famous business model. High expectations and disciplined, consistent execution are embedded in the company's DNA. "We don't tolerate businesses that don't make money," founder Michael Dell tells HBR. "We used to hear all sorts of excuses for why a business didn't make money, but to us they all sounded like 'The dog ate my homework.' We just don't accept that." In order to double its revenues in a five-year period, the company had to adapt its execution-obsessed culture to new demands. In fact, Michael Dell and CEO Kevin Rollins realized they had a crisis on their hands."We had a very visible group of employees who'd gotten rich from stock options," Rollins says. "You can't build a great company on employees who say, 'If you pay me enough, I'll stay.'" Dell and Rollins knew they had to reignite the spirit of the company. They implemented an employee survey, whose results led to the creation of the Winning Culture initiative, now a top operating priority at Dell. They also defined the Soul of Dell: Focus on the customer, be open and direct in communications, be a good global citizen, have fun in winning. It turned outto be a huge motivator. And they increased the focus on developing people within the company. "We've changed as individuals and as an organization," Rollins says. "We want the world to see not just a great financial record and operational performance but a great company. We want to have leaders that other companies covet. We want a culture that makes people stick around for reasons other than money."
