Abstract
A value stream is all the actions required to bring a product through the main flows essential to every product. It begins at the "door-to-door" production flow level and allows you to see the entire picture. It identifies waste and the sources of waste. Provides a common language and questions current decisions that happen by default. It eliminates bias improvement picking. It links material and information flow and gives a qualitative description of how your facility should operate.
An excellent spot for observing the value stream is the aisle of the supermarket. for it is here that a thousand streams empty into the arms of the customer. Not only does the flow of the physical product culminate in the supermarket aisle, as pulled forward by the decisions of the shopper, but also the process of product development as new products are launched. Indeed, Taiichi Ohno found this vantage point in the modern supermarket so stimulating that it inspired him in 1950 to invent the new system of flow management we now call Just-in-Time (JIT).
In the past couple of years we have been putting ourselves in the aisle, to think through value stream for specific products in a search for muda. To do this we have started to map out every step - each individual action - involved in the process of physical production and order-taking for specific products.
The method is based on a simple premise. Just as activities that can't be measures can't be properly managed, the activities necessary to create, order, and produce a specific product which can't be precisely identified, analyzed, and linked together cannot be challenged, improved (or eliminated together), and, eventually, perfected. The great majority of management attention has historically gone to managing aggregates - processes, departments, firms - overseeing many products at once. Yet what's really needed is to manage whole value streams for specific goods and services.
Our initial objective in creating a value stream "map" identifying every action required to design, order, and make a specific product is to sort these actions into three categories: (1) those which actually create value as perceived by the customer, (2) those which create no value but are currently required by the product development, order filling, or production systems and so can 't be eliminated just yet; and (3) those actions which don't create value as perceived by the customer and so can be eliminated immediately. Once this third set has been removed , the way is clear to go to work on the remaining non-value- creating steps through use of the flow, pull, and perfection techniques.
