What are the sectors of the external business environment, and how do they influence business decisions?

"Businesses do not operate in a vacuum but rather in a dynamic environment that has a direct influence on how they operate and whether they will achieve their objectives. This external business environment is composed of numerous outside organizations and forces that we can group into seven key subenvironments: economic, political and legal, demographic, social, competitive, global, and technological. Each of these sectors creates a unique set of challenges and opportunities for businesses. Business owners and managers have a great deal of control over the internal environment of business, which covers day-to-day decisions. They choose the supplies they purchase, which employees they hire, the products they sell, and where they sell those products. They use their skills and resources to create goods and services that will satisfy existing and prospective customers. However, the external environmental conditions that affect a business are generally beyond the control of management and change constantly. To compete successfully, business owners and managers must continuously study the environment and adapt their businesses accordingly. Other forces, such as natural disasters, can also have a major impact on businesses. While still in the rebuilding stage after Hurricane Katrina hit in 2005, the U.S. Gulf Coast suffered another disaster in April 2010 as a result of an explosion on the Deepwater Horizon oil-rig, which killed 11 workers and sent more than 3 million barrels of oil into the Gulf of Mexico. This event, which played out for more than 87 days, severely affected the environment, businesses, tourism, and people’s livelihoods. Global oil conglomerate BP, which was responsible for the oil spill, has spent more than $60 billion in response to the disaster and cleanup. Seven years after the explosion, tourism and other businesses are slowly recovering, although scientists are not certain about the long-term environmental consequences of the oil spill. No one business is large or powerful enough to create major changes in the external environment. Thus, managers are primarily adapters to, rather than agents of, change. Global competition is basically an uncontrollable element in the external environment. In some situations, however, a firm can influence external events through its strategies. For example, major U.S. pharmaceutical companies have been successful in getting the Food and Drug Administration (FDA) to speed up the approval process for new drugs. In recent years, the five largest companies in the S&P Index—Google, Facebook, Amazon, Microsoft, and Apple—have spent close to $50 million on lobbying activities in the nation’s capital in an effort to help policy makers understand the tech industry and the importance of innovation and an “open” internet."
