Kanban is a "pull system". What exactly does that mean? Instead of constantly producing items or overstocking, the resource is "pulled" when it is needed. An example is making a car after the customer's order is in, not mass producing in hopes of someone purchasing a prepackaged model.

Healthcare is notorious at underutilizing Kanban, however, it is getting better at its application. A prime example is stocking supplies in an Emergency Department. Traditionally, stock would be added to any bin, everyday, regardless if it is genuinely needed - tying into one of the wastes. In hospitals where Kanban is applied, there are cards that indicate what the par level is, and stock is brought up to that level. Par levels are the maximum amount of supplies needed.

Think about areas you work/live. I am sure we have all seen areas that could have been served well through this. Think back to any of the case studies you have read thus far; which case do you feel Kanban best applies? Why?
