In 2023 we compared a JPY 7.4 billion dedicated-volume proposal with JPY 4.6 billion for flexible assembly. The first emphasised output in a narrower product range; the second supported a different mix of industrial assemblies. A comparison based primarily on total units would have made the dedicated line look more ambitious. I wanted the institution to decide which customer work it intended to pursue before treating either capacity description as the measure of strategic success.
Takuma Nagisawa, our fictional industrial investment director, supported the dedicated proposal. He argued that a clear volume commitment could focus the business and make better use of its manufacturing experience. That case deserved attention. My preference for flexible assembly was not an assumption that flexibility always creates more value. It reflected the direction we were choosing towards more varied assembly work, with the applications and customer requirements that direction would bring. The alternative's scale was attractive, but it represented a different emphasis.
I recommended the JPY 4.6 billion option. The capital decision remained with the authorised body, while engineering and operating leaders assessed the capability, quality, safety and practical requirements. I did not select equipment or certify output. My contribution was to connect the investment choice with the business the company wanted to develop and to keep the narrower volume opportunity we were giving up inside the discussion. The approved direction required a different commercial effort as well as physical investment.
The JPY 2.8 billion difference between the proposals was not a realised saving. The scopes, product mixes and intended outputs were different, so subtracting their budgets did not establish that we had bought the same undertaking more cheaply. Nor did the selected option prove that the dedicated proposal would have failed. We chose a capability and accepted the opportunities it would leave outside our immediate direction. That is the trade-off I would want a reader to understand before quoting either amount.
The case made my view of industrial strategy more concrete. Capacity should follow the work the business intends to become good at, with the responsible specialists explaining what the proposed assets can support. A large output number can be useful evidence, but it cannot choose the company's future on its own.
