解説

問 29

Incorrectア
There is no standard management-analysis framework that uses ‘technology and product’ as its axes, and this is not PPM’s evaluation axis. PPM’s axes are market growth rate and market share.
イ
正解 PPM (Product Portfolio Management) is a technique that places multiple businesses or products on a 2 × 2 matrix, with ‘market growth rate’ as the vertical axis and ‘market share (relative market share)’ as the horizontal axis, in order to examine how management resources should be allocated. The four quadrants are called ‘Star’ (both growth rate and share are high), ‘Cash Cow’ (low growth rate but high share), ‘Problem Child’ (high growth rate but low share), and ‘Dog’ (both growth rate and share are low). Therefore the evaluation axes are ‘market growth rate and market share’, so イ is correct.
Incorrectウ
Using ‘product and market’ as the axes belongs to the Ansoff growth matrix (which classifies four growth strategies: market penetration, product development, market development, and diversification), not PPM’s evaluation axis.
Incorrectエ
‘Strengths/weaknesses and opportunities/threats’ is the framework of SWOT analysis (internal-environment strengths/weaknesses × external-environment opportunities/threats), not PPM’s evaluation axis.

ここがポイント

The evaluation axes of PPM (Product Portfolio Management) are ‘market growth rate’ (vertical axis) and ‘market share’ (horizontal axis); businesses are sorted into the four quadrants of Star, Cash Cow, Problem Child, and Dog to optimize the allocation of management resources.
Distinguishing similar frameworks: product × market = Ansoff growth matrix; strengths/weaknesses × opportunities/threats = SWOT analysis.
