What is VSM?


This is a fundamental tool in the analysis of the processes of any organization.

The Value Flow and the Information Flow are visually displayed in the analysis, making the correlation between the two evident.

The symbols used are very simple and constitute a common language to easily interpret the operations, their characteristics, the transports and the transfer of information.

  • How is a VSM implanted?

1) Identify the family of products to draw:

A family of products are those that share time and equipment within a process.

These can be identified through a product-process matrix.

2) Capture the current process identifying inventories between operations, material flow and information:

At this stage, the current VSM must be made showing the information flow and the product flow.

3) Analyze the vision of how the future state should be.

In this stage, the operation of a short-term process is established, reflecting what type of processes are going to be integrated, the number of operators and space required, number of stock in the process, etc.

4) Shape the future VSM:

The main objective of the Value-stream Map (VSM) is to indicate the sources of waste, so the implementation of this future must be done in a short period of time, the goal is to build processes that are linked to customers, working at the Tack time, in continuous flow and pulled by the client (Pull).

In this process, the following must be indicated:

- Bottleneck process

  • Place where products and resources (human and machinery) are wasted
  • Existing inventory
  • Proper solutions to eliminate them.

5) Action and implementation plan:

An Action Plan must be made that includes the future changes that are going to take place and track them.
