One of the main goals of an organization is to beat its counterpart in whatever way we can. For an organization to ensure that it must be effective in leading, planning, organizing and controlling its resources and materials to achieve its performance objectives. In other words, management. There are four main types of management: classical, behavioral, quantitative and now the modern approach to management. The modern approach states that there is no single right method of management. A successful organization uses all types of management. A good example of this is the film Lean on Me, starring Morgan Freeman as Joe Clark, the film's protagonist. Joe is a very talented teacher, very proud of his work, but due to certain events (budget cuts), he has to make very important decisions regarding his future at East Side High, New Jersey. After Joe Clark's resignation, things get worse at East Side High, so after 20 years, Joe is once again called upon to serve as principal of this once great school. Her goal was to score an average of 75 percent on the state basic skills test. This goal might be easy at any school, but then again, East Side High wasn't just another school. The previous year, the score was 33%. The school was filled with drug dealers, crime, graffiti and other things. So it took a miracle to increase the school's literacy average by about 40 percent. Joe Clark uses many different management theories, some controversial, to achieve his goal. The film was set in the mid-1980s, so at that time the modern approach to management had not come into existence, but Joe seemed to operate like the modern approach to management. He used many different theories to accomplish his difficult task. Classical management assumes that people are rational. They make logical decisions to maximize their profit.
