"Pull systems are a key aspect of any lean system. Many wastes are inherently eliminated by capping inventory levels and controlling up-stream processes based on their customer demand. Many companies employ kanban systems to control their inventory. While this is a very effective solution, kanban systems can be difficult to implement and very resource-intensive to manage.
If I were tasked with implementing a new workplace pull system, I would focus on creating well-defined min/max inventory levels for key processes. Once appropriate min/max levels are established, I would easily implement visual management controls to control the inventory upstream and downstream processes. Once success was demonstrated in a few areas, I would work to yokoten to other areas."
