Which is an element of the just-in-time system (pull system)?

While a master schedule can be a component of production planning, it is not an inherent feature of the just-in-time system. The master schedule focuses on planning production activities and timelines, which may contribute to efficiency but does not specifically align with the JIT principle of reducing inventory levels.

An interrupted flow process contradicts the goals of a just-in-time system. JIT emphasizes smooth and continuous flow to avoid delays and inefficiencies. Interruptions can lead to increased lead times and higher inventory levels, making this choice incompatible with JIT principles.

Coordinating movements may pertain to logistics and material handling but does not specifically represent a characteristic of a just-in-time system. JIT focuses more on inventory reduction and demand-driven production rather than the coordination of physical movements, which is a broader operational concern.
