When Blake and Mouton came out with a tool that used only two dimensions or axis, is struck a cord with its simplicity. Each experience that we have will call for varying degrees of emotions and approaches to task results. It is based on the theory that each person tends to have one or two dominant styles. The very simplicity that makes a tool like this so popular, cannot possible accurately predict the complexity of human nature. However, it can help us get a handle on the various approaches taken by individuals.
People try to pigeon-hole the four styles of people into certain categories.
For example, managers are drivers, human resource personnel are persuaders, programmers are analysis's, etc. This is simply untrue. Where I once worked, our human resource contact was a driver, our manager was a persuader, one on the employees on the bottom of the rung was a driver, and one of our best technical persons was an organizer. The goal of using such a tool in a team setting is to realize that people look upon things with a different viewpoint than you. Also, it takes all types to form an effective team.
