解説
問 23
Incorrectア
Improving the productivity of the sales department is an issue addressed by a Sales Force Automation (SFA) system or by business improvement. JIT is a method that targets inventory and processes on the manufacturing (production) floor, and it does not directly raise the productivity of the sales department.
Incorrectイ
Building long-term relationships with customers is an issue that Customer Relationship Management (CRM) aims to achieve. Because JIT targets the internal production and supply mechanisms, it is not a method aimed at building relationships with customers.
Incorrectウ
Grasping the sales status of products on an individual-item basis is a function realized by a POS system (Point-Of-Sale information management). JIT is a method aimed at making production and inventory more efficient, and it is not intended for grasping sales data on an individual-item basis.
- エ
正解 Just-In-Time (JIT) is a production management concept, typified by the Kanban method, in which each downstream process withdraws from the upstream process only what it needs, when it needs it, and in the amount it needs, and produces accordingly. By eliminating overproduction and stagnation between processes, the intermediate inventory of semi-finished goods (work in progress) and parts can be kept to a minimum. Therefore, the issue that introducing JIT can be expected to solve is to reduce the inventory quantity of semi-finished goods and parts, so エ is correct.
ここがポイント
- Just-In-Time (JIT) is a way of producing and supplying only the items that are needed, when they are needed, and in the amount needed. It forms the core of the Kanban method and Lean production, and it aims to reduce intermediate inventory (semi-finished goods and parts) and eliminate waste.
- Distinguish the targets of similar terms: sales productivity is handled by SFA, customer relationships by CRM, and individual-item sales tracking by POS, while JIT targets the domain of production and inventory.
