Management involves planning, organizing, and overseeing work to accomplish common goals. The basic tasks of a manager are to plan actions, implement those plans, and track performance. Historically, management focused on efficiently producing goods, but now emphasizes creating value for customers by meeting their needs. Good management analyzes business models, examines competitors to find better ways of doing things differently, and measures short and long-term performance. Innovation is also important for management so companies can adapt to an uncertain future.
