"Information is the manager's main tool, indeed..." - Quote by Peter Drucker

“Communication always makes demands. It always demands that the recipient become somebody, do something, believe something. It always appeals to motivation.”

“Growth that adds volume without improving productivity is fat. Growth that diminishes productivity is cancer.”

“Concentration is the key to economic results. No other principle of effectiveness is violated as constantly today as the basic principle of concentration.... Our motto seems to be, "Let's do a little bit of everything."”

“War is ninety percent information.”

“I think that there's a power in that [information through tweets and sound bites ]. There's also a danger, what generates a headline or stirs up a controversy and gets attention isn't the same as the process required to actually solve the problem.”

“These technologies can make life easier, can let us touch people we might not otherwise. You may have a child with a birth defect and be able to get in touch with other parents and support groups, get medical information, the latest experimental drugs. These things can profoundly influence life. I'm not downplaying that.”

“Treat the large as the small and the few as the many.”

“To be a manager requires more than a title, a big office, and other outward symbols of rank. It requires competence and performance of a high order.”

“My observation is that whenever one person is found adequate to the discharge of a duty... it is worse executed by two persons, and scarcely done at all if three or more are employed therein.”
