問 34
Incorrectア
Analyzing from the four perspectives of “strengths, weaknesses, opportunities, and threats” describes SWOT analysis, which is a different method from PPM that uses the two axes of market share and market growth rate. The stated purpose does not match.
Incorrectイ
Achieving differentiation from other companies through core businesses built on the company's own proprietary technologies and know-how is the idea of core-competence management, which differs from PPM's purpose of deciding the allocation of management resources.
Incorrectウ
Determining which stage—“introduction, growth, maturity, or decline”—a product launched into the market is in, and devising sales-promotion measures, is the concept of the product life cycle, not the purpose of PPM.
- エ
正解 PPM (Product Portfolio Management) is an analysis method that uses a matrix with market growth rate on the vertical axis and market share (relative market share) on the horizontal axis, classifying multiple products or businesses into four categories: “Star,” “Cash Cow,” “Question Mark,” and “Dog.” Its purpose is to identify which quadrant each business falls into and, on that basis, to decide the optimal allocation of limited management resources—concentrating funds on fields expected to grow and withdrawing from declining fields. Option エ, which correctly states these two axes and the resource allocation, is the correct answer.
- PPM is a method that uses a two-axis matrix of “market growth rate × market share” to classify products or businesses into Stars, Cash Cows, Question Marks, and Dogs, and thereby decide the optimal allocation of management resources.
- The question tests the distinction from easily-confused concepts: SWOT analysis (strengths, weaknesses, opportunities, threats), core competence (differentiation through core capabilities), and the product life cycle (stages from introduction to decline).
