Value stream mapping uses flowcharts to analyze and then improve on the delivery of products and services. Value stream mapping (VSM) is based on the concept of value streams – which are a series of sequential steps that explain how a product or service is delivered to consumers.
| Value Stream Mapping (VSM) | Key Elements | Analysis | Implications | Applications | Examples |
|---|---|---|---|---|---|
| Definition | Value Stream Mapping (VSM) is a lean management tool used to visualize, analyze, and improve the flow of materials and information within a process or value stream.

Understanding value stream mapping
Value stream mapping enables businesses to analyze each step and whether it is adding value. Importantly, value stream mapping also allows intelligent, holistic refinement of the whole process.
In other words, it assigns value to a step on the condition that the value it obtains does not come at the expense of another step.
All VSM initiatives have start and end points known as fenceposts, which differ according to predetermined goals and objectives.
As a result, VSM can be utilized for any individual product or service for any type of business.
For example, the process of a car dealership delivering a new car to a customer might have 35 steps.
After mapping out the process using VSM, company executives found that only 10 added any real value to the consumer.
By focusing on the 10 steps in more deal, the dealership was able to streamline its delivery process and reduce consumer wait times.
Three components of every value stream map
Each map typically consists of three sections:
Information flow
This component illustrates the communication of information or the transmission of data crucial to the process.
In the case of the car dealership, a sales manager may accept applications for financing and then forward approved requests to the finance company.
Product flow
This component documents the steps required to take a product or service from concept to delivery.
However, value stream mapping can also be used to “zoom in” on particular steps of the product development process.
Indeed, there is no limit on the level of detail that can be analyzed for each step.
Time ladder
Although rather simplistic, the time ladder provides a visual representation of the value stream timeline.
Time ladders denote the time that a product spends on each step, known as the process time.
They also denote waiting time, or the amount of time a product has to wait before proceeding to the next step.
Ultimately, both are used in the calculation of lead time – or the total amount of time it takes between receiving a consumer order and the fulfillment of that order.
Advantages and disadvantages of value stream mapping
Advantages
Value stream mapping is still relatively new in the business world, so there is potential that early adopters gain a competitive advantage.
It’s also a powerful method for identifying wastage in a process. Wastage often refers to manufacturing, but in VSM it more generally refers to any step that does not add value to the consumer.
With a focus on providing consumer value, the business can align with its core values and brand identity.
Value is of course something that consumers are willing to pay for, so businesses should utilize the incremental improvement capability of VSM wherever possible.
Disadvantages
There is somewhat of a learning curve to creating a VSM framework. It often requires a substantial investment of time and money initially, and if not prepared correctly can become a source of wastage in itself.
As with most things, the potential rewards of virtual stream mapping must outweigh the risks.
Smaller businesses with less capital and less complicated processes may derive little to no benefit from using VSM principles.
Value stream mapping vs. process mapping
Like value stream maps, process maps are a planning and management tool that visually describe the flow of work and the individual steps involved.
In other words, both are used to optimize processes and increase efficiency.
But there are also several important differences between the two approaches. We have outlined some of these in the following sections.
Level of detail
Value stream mapping offers businesses a broader, more holistic view of a process.
They are better suited to analyzing major functions and tend to be executed as part of a strategic improvement over a period of six months or so.
Process mapping, on the other hand, provides a more detailed view of the process.
This makes it ideal for specific tasks or steps within a function. Process mapping is a tactical management tool that is typically executed over a period of one to two months.
Each map shows decision points and points where the process crosses departments or functions.
Level of difficulty
Compared to process mapping, the level of difficulty in implementing value stream mapping is much higher.
When a VSM is interpreted or assessed incorrectly, there can be negative long-term ramifications for the business.
This is not to say that the creation of a process map is easy, however. One of the most significant challenges a business will face with process maps is the absence of precise objectives.
For an initiative to be effective, the business must identify the strengths and weaknesses of a methodology early on.
Application
As we touched on earlier, VSM is used to analyze major functions. This makes it better suited to production environments where businesses are looking for growth in multiple functions such as machinery and inventory.
Value stream mapping can also offer a broad view of the product life cycle from production to customer and can detail the wait time between major functions.
Conversely, process mapping is more of a decision-making tool that evaluates information flow across various departments.
This makes it the tool of choice for businesses that are focused on decision-making optimization and information handoffs within an office environment.
Level of involvement
Since value stream mapping is more of a strategic management tool, it is commonly implemented by senior-level executives with the power and requisite experience to make important decisions.
The relatively less complicated process map tends to be used by frontline employees or low-level managers to solve daily problems in a single process or a single group.
Process mapping may also be used whenever standard work does not exist.
Though we have listed some of the major differences between value stream mapping and process mapping, there is no reason why both cannot be used at the same time or combined for maximum effectiveness.
Many organizations, for example, identify a process bottleneck using VSM and then incorporate a process map for the affected step(s).
Drawbacks of Value Stream Mapping
Complexity in Implementation:
- Steep Learning Curve: Properly implementing Value Stream Mapping (VSM) can be complex, requiring a thorough understanding of the process and specialized training.
- Time-Consuming: The development and analysis of value stream maps can be time-consuming, especially for large or complex processes.

- Possible Oversimplification: In non-manufacturing contexts, VSM might oversimplify complex processes, leading to incomplete or misleading analysis.
Dependency on Accurate Data:
- Reliance on Quality Data: The effectiveness of VSM is heavily reliant on the accuracy and completeness of the data used.
- Potential for Data Collection Errors: Errors in data collection can significantly impact the analysis and resulting improvement strategies.
Organizational Resistance:
