Value Stream Mapping 101

Updated: May 30, 2023

Using flow charts, diagrams, and graphs, Value Stream Mapping (VSM) is a process and tool used to visualise the flow of material and information within an organisation. This helps to clearly demonstrate the steps involved in a production process for example, from the beginning to the end, from the raw materials to the finished product and all the steps between.


In a VSM, each step in the production process is represented by a symbol or icon, and the flow of materials and information is shown as boxes and arrows connecting the different steps. The map also includes information about the time required for each step, the amount of inventory being held, and the number of resources being used, such as workforce, equipment, and materials.


VSM helps to identify waste by highlighting areas where resources, such as time, effort, and materials, are being used inefficiently.


By using VSM, businesses can identify areas of waste, such as:


A Closer Look at Excess Inventory


Excess inventory, lingering longer than required, is akin to an unseen anchor, silently dragging the efficiency and profitability of your production process down. This surplus, while seeming like an assurance against demand fluctuations fails to contribute any added value to your customer. Instead, it devours resources, space, and capital that could otherwise be invested in growth and innovation.


VSM, a strategic tool for lean management, comes to the rescue by illuminating areas plagued with overstocking. It paves the way for actionable improvements, transforming your inventory management from a cost-generating challenge into a streamlined, waste-reducing powerhouse.


Deciphering the Enigma of Unnecessary Steps


The voyage from raw materials to the finished product is often dotted with steps that, on closer inspection, add no substantial value for the customer. These could be redundant processes, excessive approvals, or even unoptimised workflows - silent siphons draining the vitality of your production process.


VSM as your guide, you can unmask these deceptive time and effort eaters, bringing them into sharp focus. VSM unfurls the blueprint of your entire production system, allowing you to meticulously scrutinise every single step.


By identifying and eliminating these non-value-adding elements, VSM empowers you to streamline your process, save resources, and enhance your product or service efficiency - all aligned towards the sole objective of customer delight.


The Hidden Impact of Waiting Times


VSM is an invaluable ally when it comes to addressing one of the most understated yet impactful bottlenecks in your production process - waiting times.


Often masked as seemingly harmless pauses, these instances when materials, information, or people are at a standstill, can quietly snowball into significant delays and inefficiencies. Be it a batch of raw materials idling before processing or critical data stuck in a bureaucratic quagmire, these instances of waiting not only distort the rhythm of production but also inflate costs.


VSM acts as a spotlight, illuminating these overlooked pauses and enabling a strategic reconfiguration of your process flow.


The result?


An agile, lean, and efficient production cycle, tuned to deliver maximum value with minimal waste.


Tackling the Issue of Overprocessing


In the quest for perfection, it's all too easy to drift into the territory of overprocessing, where excessive time or effort is invested in certain stages of the production process. This overzealous focus can inadvertently dampen overall efficiency and burden your operations with unnecessary costs. But fear not, Value Stream Mapping (VSM) is here to steady the ship.


Acting as a diagnostic tool, VSM can precisely pinpoint these areas of excessive exertion, enabling a thorough analysis and subsequent refinement. By revealing the extent of overprocessing, VSM sets the stage for judicious resource allocation and balanced workflow, driving your operations towards optimal productivity and cost-effectiveness.


By using VSM to identify waste, businesses can identify opportunities for improvement and prioritise changes that will have the greatest impact on reducing waste and improving performance.


The goal of VSM is to create a lean production process that delivers high-quality products or services to the customer with the minimum amount of waste and effort. It also helps to identify opportunities for improvement and collaboration throughout the value chain.


By using Value Stream Mapping, businesses can make informed decisions about their processes and prioritise changes that will have the greatest impact on improving performance and customer satisfaction.
