Efficiency is not just a mere trend that is being followed blindly. It is the method to defeat cutthroat competition and succeed in today’s volatile business environments. This is where Value Stream Mapping (VSM) comes into play – the tool which can change your production flow and, by defining and eradicating waste, bring the processes to a state of high efficiency. But what is Value Stream Mapping, and how can it help take your operations to the next level?

In this article, we give you a guide on how to easily optimize the operations of your company across all departments using value stream mapping

Understanding Value Stream Mapping

Value Stream Mapping (VSM) is a tool often employed in lean management to identify and analyze the manufacturing processes and flows required to deliver a product to the customer in its best shape. 

Unlike a simple process map that only documents steps, VSM offers a clearer picture of the process regarding value-added and non-value-added activities. It helps manufacturers highlight the areas that require development and increase production speed where necessary.

The Elements of Value Stream Mapping

To understand what value stream maps are, you need to get a grasp of the key elements this technique has, and there are:

  • Supplier and Customer Icons: These are usually located at the initial and final point of the map, depicting the supply chain’s flow from the supplier to the customer, like a balance sheet.

  • Process Icons: These include different activities commonly carried out within the production process.

  • Data Boxes: These are placed under each process icon and include data; like cycle time, downtime, and changeover time.

  • Flow Arrows: These depict the direction of material and information flow within the system.

Once you've got all these elements down, you can begin to create a value stream map that will improve your operations and reduce bottlenecks.

Advantages of Value Stream Mapping

Value Stream Mapping is one of the most effective change management techniques for your business, and it has a lot of benefits like:

Identifying Bottlenecks

The first and most obvious benefit of VSM is its capacity to point out a bottleneck – a section of your production line that takes too much time. 

This way, by identifying these areas, you can go ahead and refine them to make the process quicker.

Eliminating Waste

Waste comes in various forms: overproduction, wait time, transportation, inventory accumulation, and so on. Concerning these aspects, Value Stream Mapping is effective in identifying and eradicating such non-value-adding activities. 

This, in turn, increases efficiency and decreases expenses, which will benefit everyone in the long run.

Enhancing Communication

It is imperative to remember that VSM is not just a tool for engineers and managers but also a communication technique with the team. It promotes an environment that allows for constant growth through clear and concise communication to avoid misunderstandings.

Improving Quality

With VSM, you can visualize relationships between different processes and this makes it easier to implement improvement interventions such as quality controls, elimination of defects and credit management.

How to implement value stream mapping in your company?

Value Stream Mapping is a visual tool that maps all the processes a particular product goes through; from raw materials to the complete product delivery to the customers.

Step 1: Choose a specific Product or Product line

Select a concrete product or a family of products you want to create a Value Stream Map for. Define your streams and determine the goal of creating this map or flowchart.

Step 2: Draw a current state map

The first activity of VSM involves developing the current state map. Start from the beginning of the production line and observe all the activities that have taken place involving the product under analysis, record the cycle time, wait time, and any kind of delay encountered. This map will serve as a starting point from which progress is assessed.

Step 3: Identify Waste

When the current state map is still under construction, it is advisable to pause the process, analyze the map, and look for waste. Observe redundancies and delays, as well as any other processes that may slow down the sequence. This stage is important for identifying where improvements or alterations must be made.

Step 4: Develop a Future State Map

Having established the waste, come up with future state maps that eliminate these wastes. This map should depict the realistic and efficient configuration of your production line, with little to no inefficiency.

Step 5: Implement Changes

Here, you should use the future state map as a reference to make changes to your production line. These can be as simple as rearranging workstations, changing the way tasks are accomplished, or even purchasing new equipment.

Step 6: Continuously Improve

A Value Stream Map is not an activity that is carried out for a one-time event but is a process that is continuously performed. Take time to review your production line, take management courses in London, and create new maps to maintain the improvements you’ve worked on.


Embracing VSM is not just about optimizing processes; it's about embracing a mindset of efficiency and innovation that can drive long-term success in today's competitive manufacturing landscape. 


Whether you are a small-scale manufacturer or a large industrial enterprise, integrating Value Stream Mapping into your operations can unlock new levels of performance and set the stage for sustained growth and success.
