Hey everyone, welcome to this lecture, what is pull system, a pole system is a vital component of the just in time concept and lean implementation is well, traditionally, organizations produce more than the customer wants and store the excess as inventory or work in progress and tend to push the finished goods to the next process. This is done with the idea of optimizing the sub process and not looking at the value stream as a whole. In a pool system, the process produces only when there is a pull from the subsequent process. This is signaled as either an empty bin or Kanban card pull system was inspired by supermarkets. In any well run supermarket. individual items are replenished as each item begins to run low on the shelf.

That is material replenishment is initiated by consumption applied to a shop floor. It means that a process shouldn't make its parts until the next process after it uses its original supply of parts. When the original supply of parts is down to a small amount of safety stock, this triggers a signal to the previous process, asking it for more parts. Why pool system? the pole system links accurate information with the process. Thus, it allows elimination of waste of waiting.

It also allows elimination of waste of overproduction and thus waste of inventory. When to use a pool system. Like most lean tools, implementing a pool system is not a one time activity. A pool system must be implemented in the business process with appropriate level of governance. It must then be monitored and studied regularly to continue making improvements in the system. With that, we come to the end of this lecture.

Thank you for attending. See you in the next one.
