Contrary to what many of us think, management or business management is actually a diverse field consisting of various sectors; it does not include any particular industry. As a matter of fact, management is an umbrella term that includes at least two dozen branches! You might have already heard of some of the streams, like financial management, human resources management, marketing management and sales management. But there are many other branches too, such as strategic management, program and project management, production management, operations management, IT management, service management, supply chain management, public relations management, research and development management, design management, risk management, quality management, change management, and more.
