解説
問 15
Incorrectア
BPO stands for Business Process Outsourcing, a management approach in which a company entrusts part of its own business processes (such as call centers or accounting) to an external specialist provider. It is not a production method for reducing inventory, so it is incorrect.
Incorrectイ
CIM stands for Computer Integrated Manufacturing, a system that uses computers to centrally integrate and manage information across design, production, sales, and more. It is a concept aimed at improving overall production efficiency, not a procurement method whose direct purpose is to avoid holding inventory between processes, so it is incorrect.
- ウ
正解 The correct answer is “ウ”, JIT. JIT stands for Just-In-Time, a method that procures and produces only what is needed, when it is needed, in the amount needed. Because each process supplies only the parts required by the next process, no excess inventory builds up between processes, which exactly matches the question condition of holding as little inventory between processes as possible. It is well known as the core idea of the Toyota Production System (kanban system).
Incorrectエ
OEM stands for Original Equipment Manufacturer (manufacturing under another company brand), which refers to producing products sold under another company brand name. It denotes a form of contract manufacturing, not a production method for reducing inventory, so it is incorrect.
ここがポイント
- JIT (Just-In-Time) = a production method that procures and produces only what is needed, when it is needed, in the amount needed, minimizing intermediate inventory between processes (the core of the Toyota Production System).
- Be careful not to confuse it with BPO, CIM, and OEM: BPO is the outsourcing of business operations, CIM is the computer-based integration of production information, and OEM is contract manufacturing under another company brand. None of them is a production method for reducing inventory.
