What is Value Stream Mapping? - Concepts and How to Use It

Explore this value stream mapping (VSM) guide to explore the key points including definition, benefits, usages, and step-by-step instructions for undertaking your own value stream analysis.

Value Stream Mapping Basic Definition

Value stream mapping (VSM) is a technique used by firms to, define, analyze and optimize the information/materials flow required to the whole production process. The model, which contains both values adding steps and non-value-adding steps from the customers' standpoint, is a bit similar to the flowchart structure. The main purpose of value stream mapping is to help managers and team leaders build an efficient and integrated resources and information flow system for their organizations. Below is an example of chair production value stream mapping. You can click on it to see more insights.

The History of Value Stream Mapping

The model was first pointed out by Charles Knoeppel in his book regarding efficient methodology. Latter, value stream mapping analysis became popular with the development of the Lean process management in the 20th century, and was used by many leading companies such as Toyota. By the 1990s, value stream mapping has been used in more worldwide sectors and fields from manufacturing to software development.

Why Use Value Stream Mapping?

The model can help us to:

Value Stream Mapping Symbols

VSM symbols have a number of common categories for the usages of all industries and fields: process, material, information, general and the extended ones. These intuitive symbols help you depict various work activities and information flows. Moreover, these symbols are not standardized so you can modify them for the specific requirements of your project. Here are the most widely used ones for each category.

Process

This category includes symbols for showing customers or suppliers, dedicated process flows, data boxes (e.g. cycle time) and the workcell (multiple processes).

Material

The section covers symbols for displaying inventory, push arrow, shipment car, material pull (removal of materials in a supermarket), and the supermarket (an inventory "supermarket").

Information

The category has symbols of the sequenced pull, the Go See Glasses (gathering information by checking details), the production kanban (triggers the production of predecided parts), the verbal information and the ERP (enterprise resource planning) and MRP (material requirements planning).

Value Stream Mapping and Six Sigma

VSM is part of the Six Sigma methodologies. These two models share the common goal of eliminating waste for a better efficiency. However, they are differences in two main aspects as shown below:

You can also find out more about the relationships between VSM and value chain analysis.

Key Applications of Value Stream Mapping

In the past, VSM was mainly used in the manufacturing industry. However, nowadays the model is also used in many other industries and fields such as engineering, finance, human resources, legal, marketing, software development, logistic, public service and many others as shown below:

How to Implement a VSM Analysis Efficiently?

Here are some common steps for you to undertake a value stream mapping analysis for nearly all industries and fields:

1. Select a product or product family group that your business wish to map out and analyze. You can do this from your customers' standpoint (price reduction, quality problems etc.).

2. Decide the scope of your map. Your team should consider the starting point (raw materials etc.) and the endpoints (end users etc.) of your VSM process.

3. Quickly list all of your process steps required to deliver the product or service. By doing so you can collect more information to fill in your gaps.

4. Determine the process details based on your work activities (both value-adding and non-value-adding ones), inventories and information flows.

5. Draft your current state VSM based on the information you got. Draw a table or data box under each process block to do so. You can also know about total process times and lead times for inventory through your processes by using time lines.

6. Collecting your data such as product cycle time, inventory size, number of operation staffs, scrap rate and net available working times. Then you can add data to related data boxes on your map.

7. Evaluate your map by thinking about capacity (e.g. inventory levels and waste), constraints, user experience (in this case you may need the customer journey mapping for more insights) flexibility and the consistency of your product lines and information flows.

8. Create your future state VSM and ideal state VSM by mapping out your process for each step. The latter ones are in a simpler structure for you to highlight and illustrate project goals. A simple ideal state value stream mapping looks like the diagram below (click on it to see more):

9. Conclude and find solutions by monitoring your results (excessive inventory, low uptime, poor quality and so on) for continuous improvement. Try to find out potential costs and determine the root causes of your product.
