解説
問 22
Incorrectア
Developing a new market is a result of “product innovation” — created through new products or new value — or of marketing; it is not a result obtained directly from process innovation, which innovates the manufacturing process.
- イ
正解 Process innovation is an effort to innovate the manufacturing process of a product itself, thereby raising production efficiency, quality, and yield, or lowering cost and time. When the process is improved and innovated, defects and variation decrease, so the improvement in product quality stated in choice “イ” is obtained as a direct result. The other choices are either the opposite of the direction normally expected from process innovation, or they describe the innovation of the product itself (product innovation); therefore the direct result of process innovation is “イ”.
Incorrectウ
Because process innovation makes the process more efficient, the production time per product should originally be “shortened.” An increase in production time is the opposite direction, so it is wrong as a result of process innovation.
Incorrectエ
The yield rate (the proportion of good products) “rises (improves)” as the process is improved. A decrease in the yield rate is a state where the process has worsened, which is the opposite of the result of process innovation and is therefore wrong.
ここがポイント
- Process innovation = innovating the processes of manufacturing or operations. Its direct results are higher production efficiency, higher quality, higher yield, and lower cost and production time.
- The creation of new products or new markets is a result of “product innovation”; grasp it as distinct from process innovation, which innovates the process.
