These environmental factors relate to the macroenvironment and form the acronym PESTEL, which helps to systematically guide the analysis and can be used as a framework for the audit of a company’s external environment. The chapter provides insight into how to examine the external environment of the global economy with an emphasis on high-tech markets. According to the PESTEL model, it explicitly adds insights on ecological and technical issues.
