  1. 1

    What is the purpose of Porter's Five Forces framework?

    Model answer

    It analyses the competitive structure of an industry in order to judge how attractive it is and how much profit can be made in it.

  2. 2

    Name the five forces in Porter's framework.

    Model answer

    The threat of new entrants, the bargaining power of suppliers, the bargaining power of buyers, the threat of substitutes, and competitive rivalry between existing firms.

  3. 3

    Explain what determines the threat of new entrants.

    Model answer

    It depends on the barriers to entry, such as the capital required, economies of scale enjoyed by existing firms, brand loyalty, patents and access to distribution.

  4. 4

    Explain the effect on profitability of low barriers to entry.

    Model answer

    New firms are attracted whenever profits rise, so competition increases and profits are competed away.

  5. 5

    Explain what gives suppliers bargaining power.

    Model answer

    Suppliers are powerful when there are few of them, when their input is essential or distinctive, and when switching to another supplier would be costly.

  6. 6

    Explain what gives buyers bargaining power.

    Model answer

    Buyers are powerful when they are few and large, when the product is undifferentiated and when they can easily switch to another seller.
