Dr. Drucker once remarked that the reason why journalists used the word "guru" was that they could not spell the word “charlatan.”

"Quality in a product or service is not what the supplier puts in. It is what the customer gets out and is willing to pay for. A product is not quality because it is hard to make and costs a lot of money, as manufacturers typically believe. This is incompetence. Customers pay only for what is of use to them and gives them value. Nothing else constitutes quality."

A worthy tribute from John A. Byrne in BusinessWeek Magazine:

"The world knows he was the greatest management thinker of the last century," Jack Welch, former chairman of General Electric Co., said after Drucker's death.

"He was the creator and inventor of modern management," said management guru Tom Peters. "In the early 1950s, nobody had a tool kit to manage these incredibly complex organizations that had gone out of control. Drucker was the first person to give us a handbook for that."

Adds Intel Corp. co-founder Andrew S. Grove: "Like many philosophers, he spoke in plain language that resonated with ordinary managers. Consequently, simple statements from him have influenced untold numbers of daily actions; they did mine over decades."

The story of Peter Drucker is the story of management itself. It's the story of the rise of the modern corporation and the managers who organize work. Without his analysis it's almost impossible to imagine the rise of dispersed, globe-spanning corporations.

But it's also the story of Drucker's own rising disenchantment with capitalism in the late 20th century that seemed to reward greed as easily as it did performance. Drucker was sickened by the excessive riches awarded to mediocre executives even as they slashed the ranks of ordinary workers. And as he entered his 10th decade, there were some in corporations and academia who said his time had passed. Others said he grew sloppy with the facts. Meanwhile, new generations of management gurus and pundits, many of whom grew rich off books and speaking tours, superseded him. The doubt and disillusionment with business that Drucker expressed in his later years caused him to turn away from the corporation and instead offer his advice to the nonprofit sector. It seemed an acknowledgment that business and management had somehow failed him.

But Drucker's tale is not mere history. Whether it's recognized or not, the organization and practice of management today is derived largely from the thinking of Peter Drucker. His teachings form a blueprint for every thinking leader. In a world of quick fixes and glib explanations, a world of fads and simplistic PowerPoint lessons, he understood that the job of leading people and institutions is filled with complexity. He taught generations of managers the importance of picking the best people, of focusing on opportunities and not problems, of getting on the same side of the desk as your customer, of the need to understand your competitive advantages, and to continue to refine them. He believed that talented people were the essential ingredient of every successful enterprise.

The Bill & Melinda Gates Foundation has an endowment of approximately $28.8 billion and has provided billions of dollars for the funding of immunization programs in poor countries and research into diseases such as malaria that is not commercially attractive for Big Pharma.

From a Time Magazine profile in 1997:

When Bill Gates was in the sixth grade, his parents decided he needed counseling. He was at war with his mother Mary, an outgoing woman who harbored the belief that he should do what she told him. She would call him to dinner from his basement bedroom, which she had given up trying to make him clean, and he wouldn't respond. "What are you doing?" she once demanded over the intercom

"I'm thinking," he shouted back

"You're thinking?"

"Yes, Mom, I'm thinking," he said fiercely. "Have you ever tried thinking?"

The psychologist they sent him to "was a really cool guy," Gates recalls. "He gave me books to read after each session, Freud stuff, and I really got into psychology theory." After a year of sessions and a battery of tests, the counselor reached his conclusion. "You're going to lose," he told Mary. "You had better just adjust to it because there's no use trying to beat him." Mary was strong-willed and intelligent herself, her husband recalls, "but she came around to accepting that it was futile trying to compete with him."

From the 1996 letter to shareholders:

An observer might conclude from our hiring practices that Charlie and I were traumatized early in life by an EEOC (Equal Employment Opportunity Commission) bulletin on age discrimination. The real explanation, however, is self-interest: It's difficult to teach a new dog old tricks. The many Berkshire managers who are past 70, hit home runs today at the same pace that long ago gave them reputations as young slugging sensations. Therefore, to get a job with us, just employ the tactic of the 76-year-old who persuaded a dazzling beauty of 25 to marry him. "How did you ever get her to accept?" asked his envious contemporaries. The comeback: "I told her I was 86."

In October 2005, Time Magazine wrote: Jobs is fastidious about technology the way a gourmet is fastidious about foie gras, and he recognizes that in an increasingly networked world, in which gadgets can't just do their own thing but have to talk to one another, that conversation will go better if Jobs has scripted both sides of it. "One company makes the software. The other makes the hardware ... It's not working," Jobs says. "The innovation can't happen fast enough. The integration isn't seamless enough. No one takes responsibility for the user interface. It's a mess."

Jobs doesn't care just about winning. He's willing to lose. He has done it often enough. He's just not willing to be lame, and that may, increasingly, be the winning approach. The iPod proved that design and ease of use are at least as important as increased functionality, and the iTunes Music Store proved that goes for smoothly integrating physical devices with online services too. "I think the definition of product has changed over the decades," observes Tony Fadell, vice president of engineering in the iPod division, who played a key role in conceiving and building the first iPod. "The product now is the iTunes Music Store and iTunes and the iPod and the software that goes on the iPod. A lot of companies don't really have control, or they can't really work in a collaborative way to truly make a system. We're really about a system."

That's one aspect of control. Here's another. What Jobs has accepted--the truth that he's willing to face and others cower from--is that new things don't want to be born. Innovation causes problems, and it's much easier simply to avoid it. In fact, it's downright tempting. Other guys may give in to that temptation but not Jobs. He's smart, but more than that, he's willing to be the guy who looks over your shoulder and tells you you're not going to make your dinner reservation tonight because you're going to be here at the office, thinking different.

For almost a quarter century, Sony's Walkman was the brand for portable music now its the Apple iPod.
