This document discusses understanding industries through environmental analysis at both the micro and macro levels. At the micro level, the key elements of the microenvironment that can directly impact businesses are the company itself, suppliers, marketing intermediaries, customers, competitors, and the public. At the macro level, PESTEL analysis is used to analyze the political, economic, sociocultural, technological, environmental, and legal external factors in the broader environment that can indirectly influence organizations. Understanding both the micro and macro environments is important for strategic decision making and developing effective marketing strategies.
