Value stream mapping (VSM) is a Lean tool used to visualize and improve the flow of materials and information required to bring a product or service to a customer. It involves mapping both the current and future state of processes to identify and eliminate waste. The goal is to optimize workflow and reduce lead times by removing non-value adding activities. VSM originated from Toyota's production system and focuses on improving productivity and quality by systematically eliminating waste.

DESCRIPTION
The Value Stream Mapping method (VSM) is a visualization tool oriented to the Toyota version of Lean
Manufacturing (Toyota Production System). It helps to understand and streamline work processes by using
the tools and techniques of Lean Manufacturing. The goal of VSM is to identify, to demonstrate and to
decrease waste in the process. Waste is defined as any activity that does not add value to the final product.
The word is often used to demonstrate and decrease the amount of "waste" in a manufacturing system.
VSM can thus serve as a starting point to help management, engineers, production associates, schedulers,
suppliers, and customers to recognize waste and identify its causes. As a result, Value Stream Mapping is
primarily a communication tool, but it can also be used as a strategic planning tool. And as a change
management tool.
In order to do this, the Value Stream Mapping method visually maps the flow of materials and information.
From the moment that the products are entering the back door as raw materials. Via all manufacturing
process steps. Until the moment that the products leave the loading dock as finished products.
Mapping out the activities in the manufacturing process with cycle times, down times, in-process inventory,
material moves, information flows, helps to visualize the current state of the process activities and guides
towards the future desired state.
The process usually includes mapping the "Current State" and the "Future State". These then serve as the
foundation for other Lean Manufacturing strategies.
2. HISTORY OF VALUE STREAM MAPPING
The use of waste removal to achieve competitive advantage inside organizations, was pioneered in the
1980s by Toyota's chief engineer, Taiichi Ohno, and sensei Shigeo Shingo and is oriented fundamentally
towards productivity rather than towards quality. The reason for this is thought to be that improved
productivity leads to leaner operations which help to expose further waste and quality problems in the
system. Thus the systematic attack on waste is also a systematic assault on the factors that are underlying
poor quality. And on fundamental management problems. The seven commonly accepted wastes in the
Toyota production system were originally (reformulation by Jones between brackets):
1. Overproduction (faster than necessary pace).
2. Waiting.
3. Transport (conveyance).
4. Inappropriate processing.
5. Unnecessary inventory (excess inventory).
6. Unnecessary motion.
7. Defects (correction of mistakes).
Peter Hines and Nick Rich have suggested the following tools (Article: "The seven value stream mapping
tools" - International Journal of Operations & Production Management, Vol. 17, No. 1, 1997, pp. 46-64.).

often used in lean transformations to find and

A lean transformation can be compared to a river
stream, in which you want your boat (the product) to
flow without getting stuck on rocks (problem causers).
To ease the flow, the water level (stock level, lead
time) could be increased; the boat will not get stuck.
Though it would create a rough stream (high costs)

Better is to keep a minimum water level (lean) and to
clear all the rocks (uncertainty, unreliability, scarcity
and more) in the stream. VSM is used to constantly
identify the rocks, clear them, and lower the water
level again."
