解説
問 26
Incorrectア
The accounting system is a mechanism that handles monetary information such as journal entries and closing; it is not directly involved in controlling order timing according to parts inventory consumption. As a linkage target it is inappropriate for the strategic goal of minimizing parts inventory.
- イ
正解 The Kanban method is a production method that realizes JIT (Just-In-Time): it procures the needed parts only when needed and only in the needed quantity, aiming to minimize parts inventory as much as possible. If the inventory management system that manages parts inventory is linked online with the “parts procurement system”, the moment when inventory is consumed and reaches the reorder point can be conveyed to the procurement side immediately, enabling ordering with no excess or shortage (automatic, timely ordering). This avoids holding excess inventory while also preventing stockouts, so the most appropriate choice is “イ Parts procurement system”.
Incorrectウ
The customer management system manages customer information and transaction history, handling information on the sales and business side. It is unrelated to replenishment ordering of parts inventory and does not contribute to the reduction of parts inventory achieved by the Kanban method.
Incorrectエ
The sales management system handles product sales (the demand side) such as order receipt and shipping. It can serve as a source of product-demand information, but it is the procurement (purchasing) process that directly replenishes consumed parts inventory. As a linkage target for minimizing parts inventory, the parts procurement system is more appropriate.
ここがポイント
- Kanban method = JIT (Just-In-Time). A production method that procures what is needed only when needed and only in the needed quantity, keeping parts inventory as small as possible.
- Replenishment of parts inventory is handled by the procurement (purchasing) process. Linking the inventory management system with the parts procurement system enables timely ordering based on inventory consumption, achieving both inventory compression and stockout prevention.
