Which factor describes how the number of customers, their importance to the business, and the cost of switching customers affect a firm?

• A. Power Of Customers
• B. Threats of New Entrants
• C. Competitive Rivalry
• D. Substitute Products

Answer: (A)

In Porter's Five Forces, the bargaining power of customers measures how much leverage buyers have to drive prices and terms based on their numbers, how important they are to the business, and how costly it is for them to switch to alternatives. When there are few customers or when a customer represents a large share of revenue, they can demand lower prices or better terms. If they are highly important to the company, they can threaten to take their business elsewhere, increasing their influence. Swapping to a competitor is easy (low switching costs), customers gain power; if switching costs are high, their power diminishes. The scenario described directly captures how customer leverage shapes a firm’s margins and terms, making it the power of customers. The other forces describe different dynamics: entry barriers for new competitors, rivalry among existing firms, and the availability of substitute products.
