This is a comprehensive way to pinpoint your colleagues at work, including your boss(es). Where do you find yourself in this scheme? Somebody who is coordinating, leading and taking initiatives might fit best into the upper left quadrant. A person who is working best in team, agreeing a lot and helping others might fit best into the lower left quadrant. If you (or your subject of investigation) is evasive, admitting and offtaking, you might be placed into the lower right quadrant. A dominant and isolated person shows tendencies of superior analytical skills, but also he might be also condemning and opposing.
It is important to use this scheme at the moment. You might see tendencies, but normaly everyone can be put in every corner, depending on the situation.
