Which of the following is a Porter's Five Force?

• A. Bargaining power of suppliers
• B. Market growth rate
• C. Customer satisfaction
• D. Product life cycle

Answer: (A)

Porter's Five Forces is a framework for analyzing the competitive pressures that shape profitability in an industry. It includes threats of new entrants, the bargaining power of suppliers, the bargaining power of buyers, threats of substitutes, and competitive rivalry.

Bargaining power of suppliers describes how much influence suppliers have over prices and terms. When suppliers are few, offer specialized inputs, or if switching suppliers is costly, they can push up costs or limit quality, squeezing the margins of firms in the industry. That's exactly the kind of structural pressure this framework is meant to assess.

The other options don’t represent a Porter's Five Force. Market growth rate is about how fast the market is expanding, not a competitive pressure. Customer satisfaction reflects a company's performance from the customer’s perspective, not a market-power dynamic. The product life cycle tracks a product’s stages over time, not a force shaping industry structure.
