Brief History and Evolution of Value Stream Mapping
Value stream mapping was born in the Toyota Production System (TPS) in the mid-20th century to improve production efficiency through lean manufacturing. Information flow mapping was part of the TPS to visualise material and information flow. This was a response to the post-war economic challenge in Japan when Toyota wanted to transform the automotive industry by reducing waste and improving flow.
The principles of value stream mapping are based on delivering value to the customer and eliminating everything that doesn’t add to that value. Over the years, this tool has spread beyond the automotive industry and is now used by many industries to optimise their operations. Today, value stream mapping is used globally to improve productivity and quality regardless of the industry. Its legacy continues to shape how organisations see and manage the workflow towards operational excellence.
Why Value Stream Mapping for Process Improvement
Value stream mapping helps identify waste and areas for improvement by showing the workflow from start to finish. This gives organisations the clarity to see where the inefficiencies are, whether it’s waiting time, duplicated effort, or unnecessary processes. By visualising each element of the value stream, teams can have meaningful conversations about performance gaps and develop targeted solutions to fix the issues.
Also, by focusing on value-added versus non-value-added activities, value stream mapping allows organisations to streamline the process. This increases operational efficiency and throughput, so products and services get to the customer faster. The insights from value stream mapping is invaluable, it drives informed decisions, creates a culture of continuous improvement and ultimately customer satisfaction and competitive advantage in the market. Using this tool is essential for any organisation that wants to succeed in their operations.

Value Stream Owners vs Functional Departments
Value stream owners and functional departments play different but complementary roles in the organisation, especially in value stream mapping. Value stream owners are responsible for the whole value stream from end to end. They focus on the material and information flow, ensuring every step adds value to the customer. This role requires a holistic view of all activities, cross-functional collaboration, and continuous improvement with a direct focus on outcomes that improve customer satisfaction.
Functional departments are structured around specific areas of expertise – marketing, engineering or production. They focus is narrower, they focus on optimising their function and achieving their departmental goals. Functional departments are good at what they do but can create silo thinking where improvements within the department don’t necessarily translate to better overall value for the customer.
The synergy between value stream owners and functional departments is key.
Effective value stream management requires functional departments to align their objectives to the overall goals set by the value stream owner so everyone is working towards the same direction. Organisations can improve efficiency, effectiveness and overall performance by engaging and communicating between these two roles.
What is a Value Stream Map
Elements of a Value Stream Map
A value stream map (VSM) consists of several elements that show the flow of material and information through the process. To analyse and improve, you need to understand these components:
- Processes: Each workflow step is represented by a rectangular box. This shows the specific actions needed to transform material into a finished product or service. This includes value-added and non-value-added activities that need to be improved.
- Information Flow: Arrows show the direction of information flow, which is how data is communicated between processes. This highlights the role of communication in making the process work smoothly and efficiently.
- Material Flow: Dashed lines show the flow of material through the process, this shows how inputs are transformed into outputs. This element helps to identify bottlenecks and delays in the supply chain.
- Lead Times: Lead times are marked beside each process. This shows the time taken for each step from start to finish, which is critical to understanding the overall efficiency of the value stream.
- Inventory Levels: Triangles at each process step show the work in progress (WIP) inventory. Monitoring inventory levels can help to identify overproduction and waste.
- Timeline: A timeline at the bottom of the map shows the cumulative lead time across all processes and can highlight the difference between value-added time and total cycle time. This visual representation helps identify areas for time reduction.
By understanding each of these elements, organisations can gain a full understanding of their process and make informed decisions to achieve operational excellence and continuous improvement.

Value Stream Mapping vs Process Mapping
While value stream mapping (VSM) and process mapping are used to improve operational efficiency, they vary in scope and focus. Value stream mapping provides a full view of the whole process, showing value-added and non-value-added activities across the whole process. Stream mapping examples show how these maps can be created using flowchart software or traditional methods like whiteboards, with real-world examples and case studies from different industries. Its main purpose is to identify waste and optimise the flow of material and information so that every step adds value to the customer. This holistic approach makes VSM very effective in lean manufacturing, where waste elimination is key.
Process mapping zooms in on specific tasks or subprocesses within a bigger system. It shows the sequential steps of a particular operation, focusing more on the details of task execution rather than the overall value delivery. Process maps can identify operational bottlenecks and inefficiencies at a detailed level and are useful for quality control or standardisation. While both tools are great for process improvement, organisations often find that combining them gives a more powerful approach to improve efficiency and continuous improvement across all levels of the organisation. By using both VSM and process mapping businesses can get a full understanding of their systems and ensure they not only streamline processes but align them to customer value.
