Nowadays, management has become an important part of society. The role of management is to help the organization make the best use of its resources to achieve its objective. Based on the objective of management, one of the theorists Henri Fayol proposed the four necessary management functions: planning, organizing, leading, controlling are the tools that managers use to achieve these objectives. (Jones 2006) This essay will describe and discuss these functions. The first function of management is planning. Planning is a process that managers use to identify and involve setting objectives and deciding the best way to achieve the objective. (Bartol 2007) Planning bridges the gap between where we are doing and where we intend to go. It predicts possible events that would not otherwise occur (MSG 2012). The planning process involves several steps which involve determining the organization's objectives, assessing the current position, considering possible future conditions, identifying possible alternative actions and choosing the best one. Planning is the criterion of thinking about objectives and making decisions to achieve the objective of the organization, which requires a systematic method. Objectives also tell managers how to achieve the end result, because managers must predict that everything will happen, avoid the problem, and fight back against competitors. An example of planning is Canon Inc Chairman Tsuneji Uchida and the main Canon company becoming the No. 1 in the global industry (Canon.Inc 2011). Tsuneji Uchida must understand what the objective and purpose of the business is. First, make the decision to protect the position and aim of the gun, to improve the operation with more diversity. Second, he creates the new camera design and new technology, he plans to do these things to maximize profits. In order to achieve the organization's goals, managers must set goals and develop an achievable plan to achieve the goals. Organizing is one of the processes of arranging people, activities, and other resources in a logical manner (Davidson 2009). Through the organizing function, managers must analyze how activities and resources should be grouped and execute the plans successfully (Bartol 2007). A manager must understand his ability to manage lower level employees, which is the most valuable in the company because they are the key to the result and implementation in planning. Then the manager will coordinate the tasks between authority and responsibility, i.e. define their role position (MSG 2012).
