Final answer:
Kanban is falsely characterized in the question as a system of lights for signaling issues; it is actually a visual scheduling system employing cards to manage production workflow and reduce waste.
Step-by-step explanation:
The statement that Kanban is a system of lights used to signal problems or slowdowns in a production process is False. Kanban is actually a scheduling system for lean manufacturing and just-in-time manufacturing (JIT). The term 'Kanban' is Japanese for 'signboard' or 'billboard'. In a Kanban system, visual signals—often cards—are used to trigger the movement of materials within a factory or production area. These visual cues help manage the workflow and ensure that each station or area has the required materials and information when they need them, thereby avoiding overproduction and reducing waste.The confusion may arise because some modern Kanban systems have integrated electronic signaling systems, which may include lights, to indicate status. However, these are enhancements to traditional Kanban card systems and are not the fundamental aspect of the Kanban methodology.
