The efficient and effective operation of a business, and study of this subject, is called management. The major branches of management are financial management, marketing management, human resource management, strategic management, production management, operations management, service management, and information technology management.
Owners may administer their businesses themselves, or employ managers to do this for them. Whether they are owners or employees, managers administer three primary components of the business' value: its financial resources, capital or tangible resources, and human resources. These resources are administered in at least five functional areas: legal contracting, manufacturing or service production, marketing, accounting, financing, and human resources.
