Everything starts with an idea. This is the first of the four jobs – the Thinkers. Builders convert these ideas into reality. This the second job. Improvers make this reality better. This is the third job. Producers do the work over and over again, delivering quality goods and services to the company’s customers in a repeatable manner. This is the fourth job. And then the process begins again with new ideas and new ways of doing business being developed as the old ones become stale.
