Peter Drucker

The productivity of work is not the responsibility of the worker but of the manager.

If analysis shows that someone's brilliant work fails again and again as soon as cooperation from others is required, it probably indicates a lack of courtesy - that is, a lack of manners.

Few companies that installed computers to reduce the employment of clerks have realized their expectations... They now need more, and more expensive clerks even though they call them 'operators' or 'programmers.'

Plans are only good intentions unless they immediately degenerate into hard work.

Company cultures are like country cultures. Never try to change one. Try, instead, to work with what you've got.

The only thing we know about the future is that it will be different.

Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window.

Rank does not confer privilege or give power. It imposes responsibility.
