Success in the knowledge economy comes to those who know themselves - their strengths, their values, and how they best perform.
Peter Drucker
Image
Accept the fact that we have to treat almost anybody as a volunteer.
Peter Drucker
Image
Decisions of the kind the executive has to make are not made well by acclamation. They are made well only if based on the clash of conflicting views...The first rule in decision-making is that one does not make a decision unless there is disagreement.
Peter Drucker
Image
Time is the scarcest resource and unless it is managed nothing else can be managed.
Peter Drucker
Image
What's absolutely unforgivable is the financial benefit top management people get for laying off people. There's no excuse for it. No justification. No explanation. This is morally and socially unforgivable, and we'll pay a very nasty price.
Peter Drucker
Image
Profit is not the explanation, cause, or rationale of business behavior and business decisions, but the test of their validity.
Peter Drucker
Image
We have tried to substitute mass for purpose. We have tried to regain military potency of defense by making it gigantic, unwieldy, complex. It never works.
Peter Drucker
Image
The correct assumption is that what individuals have learned by age twenty-one will begin to become obsolete five to ten years later and will have to be replaced-or at least refurbished-by new learning, new skills, new knowledge.
Peter Drucker
Image
Loafing is easy, but leisure is difficult.
Peter Drucker
Image
You can't manage what you don't measure.
Peter Drucker
Image
Some of the best business and nonprofit CEOs I've worked with over a sixty-five-year consulting career were not stereotypical leaders. They were all over the map in terms of their personalities, attitudes, values, strengths, and weaknesses.
Peter Drucker
Image
What people in business think they know about the customer and market is likely to be more wrong than right...the customer rarely buys what the business thinks it sells him.
Peter Drucker
Image
The task of leadership is to create an alignment of strengths so strong that it makes the system's weaknesses irrelevant.
Peter Drucker
Image
The young knowledge worker whose job is too small to challenge and test his abilities either leaves or declines rapidly into premature middle age, soured, cynical, unproductive.
Peter Drucker
Image
The only industries that function well are the industries that take responsibility for training. The Japanese, you know, assume that when you first come to work you know absolutely nothing. School isn't preparation for work and never was.
Peter Drucker
Image
Plans are only good intentions unless they immediately degenerate into hard work.
Peter Drucker
Image
The final test of greatness in a CEO is how well he chooses a successor and whether he can step aside and let the successor run the company.
Peter Drucker
Image
If you want it, measure it. If you can't measure it, forget it.
Peter Drucker
Image
No other area offers richer opportunities for successful innovation than the unexpected success.
Peter Drucker
Image
The large organization has to learn to innovate, or it won't survive.
