Who says elephants can't dance ? Louis V. Gerstner Jr. & IBM

I have quoted here some of the good management learnings from the book, "Who says elephants can't dance ?" about the life of Louis V. Gerstner and IBM. This book is widely referred to management students.
In this book, by elephants, Louis is referring to big corporations/companies such as IBM. People have a feeling that small companies are better than big companies as there is excessive bureaucracy in big companies and decision making is as a result a lengthy process. Louis denies this misconception and believes that even elephants (meaning big corporations) can dance and if they get to the dance floor, ant (meaning small companies) will have to leave the dance floor.

• The success factors of an industry - Decentralized decision making balanced by central strategy and strong customer focus.
• People always do what you inspect and not what you expect.
• There are four kinds of people in the world -

1. Those who make things happen

2. Those to whom things happen

3. Those who watch things happen

4. Those who don't even know things are happening
