One of the main goals of an organization is to beat its counterpart in the way we can. For an organization to ensure it must be good at leading, planning, organizing and controlling its resources and materials to achieve 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 good management method. 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 protagonist of the film. Joe is a very talented teacher, very proud of his work, but due to some events (budget cuts), he has to make some very important decisions about 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 take on the role of principal of what was once a great school. His goal was to average a 75% on the state basic skills test. This goal might be easy in any school, but on the other hand, East Side High was not just another school. The previous year the score was 33%. The school was full of drug dealers, crime, graffiti and other things. Therefore it took a miracle to increase the school's literacy average by about 40%. 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 yet arisen, but Joe seemed to work 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.
