Story One: the keynote speaker at a current regional assembly of APICS (American Manufacturing and Stock Management Society) featured a excessive-stage govt from a hospital materials provide firm, one of many largest within the nation. After an informative however considerably lackluster presentation, in the course of the query interval, a hand shot up. “How are Kanban strategies being utilized in your hospital provide chain technique?” was the query. After a brief deer-in-the-headlights second, the speaker responded: “What’s Kanban?”.<\/p>\n
Story Two: a current assembly in Las Vegas of hospital provide chain professionals featured a speaker on the subject of Kanban. The push-again from the gang was powerful, with particular person after particular person emotionally defending the Par Level system at the moment in use at their hospital. The speaker was in a position to reply every problem effectively, however the debate got here to a conclusion when one of many contributors stood up and mentioned “Hey guys. Let’s be sincere. Par Level does not work that effectively. Kanban is the longer term. Recover from it.”<\/p>\n
There could also be two questions in your thoughts at this level within the article: what’s Par Level and what’s Kanban? These two phrases confer with strategies used to handle provides and supplies, in a hospital or anywhere. We affiliate the Par Level system with hospitals as a result of just about nobody else makes use of it, for causes we will see. Each strategies share the concept that we must always arrange a goal quantity of fabric for any given merchandise and placement, by no means have greater than that quantity, and by no means run out. On these factors the 2 strategies are in settlement. The place they diverge is in the best way that they suggest to perform these objectives.<\/p>\n
The Par Level system proposes that we depend the variety of gadgets remaining in a particular location, and easily exchange the gadgets which are wanted to convey the amount “as much as par”, i.e. again as much as the goal amount. What could possibly be simpler, proper? In fact that entails frequent counting, which is a wasteful and non-worth-including exercise, and it requires frequent journeys again to the stockroom, which is one other wasteful and non-worth-including exercise. Worst of all, the counting that’s required is so onerous that the majority provide handlers do not do it, they merely “eye-ball” the supplies and make an informed guess on the provides to be refilled. Many provides handlers are skilled and handle to maintain up to the mark more often than not, however because the saying goes, that is a hell of a method to run a railroad. The finish end result: actually extreme effort and possibly sub-par outcomes as measured by shortages, group of storage areas, and employees satisfaction.<\/p>\n
As we mentioned, the Kanban technique has the identical total objectives however approaches the replenishment course of otherwise. Kanban is a Japanese phrase meaning “sign”, and creating a transparent sign is on the coronary heart of the Kanban technique. As a substitute of counting the whole lot on a regular basis, Kanban proposes that we arrange a sign system in order that we are able to reply solely to these gadgets that want refilling. We do that by dividing the amount to be saved into a number of sub-portions. For instance, we’d take a par stage of 100 items and divide it into two portions of fifty. No motion is required till the primary 50 are gone. We’ll then exchange 50, however proceed to make use of the remaining 50 in the course of the refill course of, so there is no such thing as a delay for lack of provides. The precise Kanban or sign could possibly be an empty bin, a card that’s eliminated and positioned in a group field, or a flag that’s raised on the container itself.<\/p>\n
This isn’t rocket science, however utilizing the Kanban technique can minimize the variety of gadgets to be counted every day all the way down to zero (none!) and the variety of journeys to the stockroom by at the very least 50%. That is the rationale that Kanban is the strategy of alternative for world-class organizations around the globe. And additionally it is the rationale why the Par Level system would by no means even be thought-about.<\/p>\n
