解説
問 24
Incorrectア
Plotting technologies on a matrix whose two axes are the competitive strength level of a technology and the technology life cycle describes a technology portfolio, which organizes the strengths and positioning of technologies. This differs from a roadmap, which shows the path of technological progress along a time axis.
Incorrectイ
Taking the amount of R&D investment and its results as the two axes, graphing the growth processes of old and new technologies to show the transition from old to new technologies, describes an S curve (technology progress curve / technology substitution), which depicts the maturation process of a technology. It is not a roadmap, which lays out the development path along a time axis.
Incorrectウ
Plotting technology development projects on a matrix whose two axes are the promise from the market side and the promise from the technology side describes a technology portfolio, which evaluates and selects which projects to focus on. This too is a positioning on two axes, not a roadmap that shows progress along a time axis.
- エ
正解 A roadmap (technology roadmap) is a chart that places time on the horizontal axis and items such as markets, products, and technologies on the vertical axis, showing along the time axis the path by which elemental technologies and required functions progress through R&D efforts. Its characteristic is that it lets you take in, on a single sheet, the future goal together with the order and timing of the technology development leading up to it. Choice エ describes exactly this definition, so it is the correct answer.
ここがポイント
- Technology roadmap = a chart that places time on the horizontal axis and markets, products, technologies, etc. on the vertical axis, showing along the time axis the path of progress of elemental technologies and required functions. It gives an overview of the order and timing of technology development leading up to the future goal.
- The key point is the distinction: positioning things on a two-axis matrix is a technology portfolio, whereas drawing a path along a time axis is a roadmap.
