Organizational behavior is a study and application of managerial skills and knowledge to people in the organization to investigate individual and group behavior. Various concepts and models in the field of organizational behavior  attempt to identify, not only the human behavior but also modify their attitude and promote skills so that they can act more effectively. This is done scientifically; therefore, organizational behavior  field is a scientific discipline. The knowledge and models are practically applied to workers, groups and organizational structure that provide tools for improved behavior  and dynamics of relationship. The field of organizational behavior  also provides various systems and models for international relationship that are applied to organizations. 
Leaders must look for indicators (effects) of individual behavior  and of groups in any organization. Indicators have a root cause beneath. As a leader, it is that symptom, which must be evaluated, and cause of human behavior  established so that if the behavior  is good, the manager can establish the norms of behaviour. If the behavior  is not conducive to achieve the organisastional objective then suitable alternative model can be applied to channelize individual behavior  towards an appropriate organizational value system and individual behavior  modified. 
An organization has three basic elements namely, people, structure, and technology. An organization must have suitable organizational structure, with appropriate number of tier and reporting system properly explained. Principle of unity of command, delegation of authority and responsibility, formulation of objectives and its allotment to various groups is very important so that workers achieve a required level of job satisfaction. They must be trained to handle sophisticated machines and equipment. It is the people, their value system, and faith in the leadership that make an organization. Leader must be able to describe, understand, predict and control individual behavior  in the organization. This is explained in the succeeding paragraphs.

     (c)  Predict:
By frequent closer interaction, a leader is in a position to identify the nature of workers. Some are more productive while the others are tardy and disruptive. In such situation, a leader should be able to handle each individual differently so that his or her actions can be channalized to higher productivity.
