Lean manufacturing tool series -13 (Value Stream Mapping -VSM)

Value Stream Mapping (VSM) – Visualize the Value

It should be obvious that an ideal business and manufacturing process should run smoothly without any interruption between steps or departments. The quickest way from point A to point B is in a straight line, and the easiest way to achieve that straight line is by using Value Stream Mapping, or VSM.

VSM is used to identify the areas in which a large amount of waste exists. This gives the quality team a good idea where to focus their efforts and lean processes. By practicing VSM, a company can also streamline their business processes and achieve record levels of productivity. More commonly known as “Material and Information Flow Mapping”, VSM seeks to analyze and optimize the flow of materials and information necessary to bring a product or service to a consumer. As you might expect, the simpler, more straight-line, and clearly defined the processes or value stream is, the more efficiently the company will run. If used correctly, VSM can be used in many different industries and processes, from customer service, to consulting services, and from optimizing manufacturing lines to paperwork reduction. No matter what industry, effort, or process, there are a few steps which outline the processes necessary for mapping the different value streams.

When it comes time to implement the VSM techniques, it should be employed in four stages.

The first is to identify what it is that is to be mapped, or what the “target” will be. Second, using the helpful hints from above, the current state of the process should be drawn. The steps, information flows, and delays that are necessary to deliver the target product or service should be included in the preliminary map.

The next step is where the magic happens. Management should be brought in to assess the current state of the value stream map it possibly identify areas which need work in creating flow by eliminating waste. And lastly, taking into account what was found in the previous step, the future VSM should then be drawn and implemented.







While it is usually a management-lead initiative, in order to effectively create an accurate VSM, a company must employ the cooperation of its line workers to help the management create an

effective VSM. Like a house without a strong foundation, without a good VSM to start with, the rest of the process will be useless.

Value Stream Mapping is one of the best ways for a company to understand its own processes and procedures. As most managers will be surprised at the inefficiencies, it is good to put them on paper so they can be addresses. Just as it can be used to identify the weak areas, it can also be used to project what the ideal VSM would look like, and use that as a reference when employing other Lean tactics to improve the performance of the company by eliminating waste. The end result is usually a stronger, leaner company that is streamlined to the point where it produces its maximum output with the least amount of defects.
