Value Stream Mapping


Value Stream Mapping Definition
• Value Stream Mapping (VSM):
– Special type of flow chart that uses symbols known as "the language of Lean" to depict and improve the flow of inventory and information.


Value Stream Mapping Purpose
• Provide optimum value to the customer through a complete value creation process with minimum waste in: – Design (concept to customer) – Build (order to delivery) – Sustain (in-use through life cycle to service)
