16 IV. Kanban will always reduce the amount of inventory in the process V. Kanban requires cross -training all workers. The Toyota P roduction Sys tem with i ts focus on flow a nd just -in-time delivery is an important p art of a ny operations cou rse or b ook and th e Kanban meth od is a k ey con cept of it. Kanban cards are a replenishment mechanism in a process where a resource (machine or operator) only produces some thing when there exists an explicit demand for it. This demand could come from the customer (e xt ernal demand) or from the subsequent resource in the process (int ernal de mand). Either way, work is now pulled t hro ugh the process, and it is demand that drive s t he f low, no t mac hine or operator availability. As we can s ee, Cha t GPT had no problems wit h this q uestion. ANSWER 7 The correct statements are: I. Deploying the Kanban system leads to pulling work through the system instead of pushing work. III. The Kanban system controls the work in process inventory. IV. Kanban will alw ays reduce the amount of inventory in the process (if implemented correctly). Kanban is a method for managing the flow of work in a production process. It is based on the principles of just- in-time production, which aims to minimize inventory and waste by only producing what is needed, when it is needed. In a Kanban system, work is pulled through the process as it is needed, rather than being pushed through the process regardless of demand. The Kanban syste m helps to control the amount of work in process inventory by using visual signals (such as cards or electronic displays) to indicate when work should be started and when it is ready to move to the next stage in the process. Kanban does not necessarily require cross -training all workers, although it may be beneficial to have a more flexible workforce that can handle multiple tasks.
