Explanation of Value stream
The complete sequence of activities, both value-adding and non-value-adding, required to bring a product or service from raw material or request through to delivery to the customer. Value stream mapping is a lean tool used to visualize, analyze, and improve the flow of materials and information across the entire value stream.
