The four primary functions of managers are planning, organizing, leading, and controlling. By using the four functions, managers work to increase the efficiency and effectiveness of their employees, processes, projects, and organizations as a whole.

The definition of a manager is a person responsible for supervising and motivating employees and for directing the progress of an organization. An example of a manager is the person who is in charge of customer service, who deals with customer disputes and who oversees and supervises customer service agents.

Great managers are able to lead teams, help them grow, and maintain full control over their business and its performance at the same time. These are the people who manage to constantly adapt to new situations, encourage others to reach their full potential, and deliver their best work, too.
