Understanding Value Stream Mapping Symbols

Introduction

Value Stream Mapping (VSM) is a method used by many organizations to identify waste and find ways to reduce it. By mapping out the flow of materials and information, companies can identify areas of improvement and create a more efficient system. In order to do this, it is important to understand the various symbols used in VSM.

The Importance of VSM Symbols

VSM symbols are the building blocks of any value stream map. They are used to represent different steps in the process, as well as the flow of materials and information. Without these symbols, it would be difficult to create an accurate map that could be used for process improvement.

Types of VSM Symbols

There are several different types of VSM symbols, including process symbols, material symbols, and information symbols. Process symbols are used to represent the different steps in the process, such as “transport” or “inspect.” Material symbols are used to represent the flow of materials, such as “raw material” or “finished goods.” Information symbols are used to represent the flow of information, such as “customer order” or “production schedule.”

Using VSM Symbols

When creating a value stream map, it is important to use the correct symbols to accurately represent the process. It is also important to use consistent symbols throughout the map to ensure clarity and understanding. By using VSM symbols, companies can create a visual representation of the process that can be used to identify areas of waste and inefficiency.

Personal Experience

In my previous job, we used VSM to identify areas of waste in our production process. By creating a value stream map, we were able to identify several areas where we could improve efficiency. One of the key findings was that we were overproducing certain products, which was leading to excess inventory and waste. By adjusting the production schedule and reducing overproduction, we were able to reduce waste and improve our overall efficiency.

FAQs
