The basic functions of management are to plan, organize, lead, motivate and control. The principles and skills involved in effective management have been studied endlessly over the centuries with various strategies and theories being adopted - many contradicting others.
As such a well-researched topic, it is often worthwhile investigating management as an academic subject for study as it is not only helpful as a qualification to add to your resume, but will provide practical skills for managing a team, business or organization.
