Think of yourself as a machine operating within a machine and know that you have the ability to alter your machines to produce better outcomes. You have your goals. I call the way you will operate to achieve your goals your machine. It consists of a design (the things that have to get done) and the people (who will do the things that need getting done). Those people include you and those who help you. For example, imagine that your goal is a military one: to take a hill from an enemy. Your design for your “machine” might include two scouts, two snipers, four infantrymen, and so on. While the right design is essential, it is only half the battle. It is equally important to put the right people in each of those positions. They need different qualities to do their jobs well—the scouts must be fast runners, the snipers must be good marksmen—so that the machine will produce the outcomes you seek.

By comparing your outcomes with your goals, you can determine how to modify your machine. This evaluation and improvement process exactly mirrors the evolutionary process I described earlier. It means looking at how to improve or change the design or people to achieve your goals. Schematically, the process is a feedback loop, as shown in the diagram on the opposite page.
