解説
問 15
- ア
正解 A technology portfolio is an analytical technique in which each technology the company owns or develops is mapped—by its positioning in the market—onto a matrix whose axes are the technology level and the maturity of technologies, so as to consider which technologies to invest in, strengthen, maintain, or withdraw from. Choice ア correctly states this core idea of showing the positioning of the company's own technologies on a matrix with axes, and is therefore the correct answer.
Incorrectイ
Showing the period from the start of development until the break-even point is reached, together with cumulative investment and cumulative profit, is a business-plan or profit-and-loss (cash-flow) chart that presents the profitability of a business or product over time; it is not a technology portfolio, which analyzes the positioning of technologies.
Incorrectウ
Showing the development schedule and target goals of the technologies to be developed, together with the relationship between the developed technologies and new products or business plans, is a description of a technology roadmap. It is a development plan along a time axis, and differs from a portfolio, which is a positioning analysis on a matrix.
Incorrectエ
Breaking down the technologies the company owns into elemental technologies and systematically presenting them in a tree structure is a description of a technology tree (technology hierarchy diagram). It organizes the composition of technologies hierarchically, and differs in both purpose and form from a technology portfolio, which shows positioning in the market.
ここがポイント
- A technology portfolio is a technology-strategy analytical technique that shows the market positioning of the company's technologies on a matrix with axes such as technology level and technology maturity, and on that basis decides on investment, strengthening, or withdrawal.
- The question asks you to distinguish it from the easily confused technology roadmap (development schedule, goals, and relationship to products = choice ウ) and technology tree (tree-structure breakdown into elemental technologies = choice エ).
