Peter Drucker

Business, that's easily defined - it's other people's money.

Never mind your happiness; do your duty.

Suppliers and especially manufacturers have market power because they have information about a product or a service that the customer does not and cannot have, and does not need if he can trust the brand. This explains the profitability of brands.

Manners are the lubricating oil of an organization. It is a law of nature that two moving bodies in contact with each other create friction. This is as true for human beings as it is for inanimate objects.

The entrepreneur always searches for change, responds to it, and exploits it as an opportunity.

Checking the results of a decision against its expectations shows executives what their strengths are, where they need to improve, and where they lack knowledge or information.

A manager is responsible for the application and performance of knowledge.

Knowledge has to be improved, challenged, and increased constantly, or it vanishes.

Teaching is the only major occupation of man for which we have not yet developed tools that make an average person capable of competence and performance. In teaching we rely on the 'naturals', the ones who somehow know how to teach.

Time is the scarcest resource and unless it is managed nothing else can be managed.

The new information technology... Internet and e-mail... have practically eliminated the physical costs of communications.

Executives owe it to the organization and to their fellow workers not to tolerate nonperforming individuals in important jobs.
