This chapter discusses Porter's 5 Forces model for analyzing competition within an industry. It introduces the 5 competitive forces as competitive rivalry, power of suppliers, power of buyers, threat of substitutes, and threat of new entrants. For each force, it provides examples of factors that influence the degree of competition, such as differentiation of products, switching costs, price sensitivity, and barriers to entry. The learning outcomes are to define and identify each of the 5 forces and understand how they can impact a business.
