Value Stream Mapping

Value-stream mapping, also known as "material- and information-flow mapping", is a lean-management method for analyzing the current state and designing a future state for the series of events that take a product or service from the beginning of the specific process until it reaches the customer. A value stream map is a visual tool that displays all critical steps in a specific process and easily quantifies the time and volume taken at each stage, Value stream maps show the flow of both materials and information as they progress through the process.

Whereas a value stream map represents a core business process that adds value to a material product, a value chain diagram shows an overview of all activities within a company.

Other business activities may be represented in "value stream diagrams" and/or other kinds of diagram that represent business processes that create and use business data.
