解説

問 26

  • ア

    正解 PPM (product portfolio management) is a method that classifies products into four quadrants according to whether their market share (vertical axis) and market growth rate (horizontal axis) are high or low. A “cash cow” is the quadrant where the market growth rate is low (meaning little new investment is required) while the market share is high (meaning it steadily generates large sales and profit). In the figure, Product A sits in the upper-left, where market share is “high” and market growth rate is “low.” It is exactly the “cash cow” that earns cash while keeping investment low, so the correct answer is “ア,” Product A.

  • Incorrectイ

    Product B is in the quadrant where both market share and market growth rate are “high” (upper-right), corresponding to a “star,” which holds a high share in a growing market. It also needs heavy investment to sustain growth, so it is not a cash cow.

  • Incorrectウ

    Product C is in the quadrant where both market share and market growth rate are “low” (lower-left), corresponding to a “dog,” which is weak in both share and growth. It is a candidate for withdrawal, so it is not a cash cow.

  • Incorrectエ

    Product D is in the quadrant where market share is “low” and market growth rate is “high” (lower-right), corresponding to a “question mark,” which is in a growing market but has a low share. It needs large investment to nurture, so it is not a cash cow.

ここがポイント
  • The four PPM quadrants: high share × low growth = cash cow, high share × high growth = star, low share × high growth = question mark, low share × low growth = dog.
  • A “cash cow” refers to a product with low growth that needs little additional investment yet steadily generates cash thanks to its high market share.
