Value Stream Mapping

A Value Stream Map is a diagram depicting the process steps associated with turning a customer need into a delivered product or service. The Value Stream Map indicates how much value each of the steps adds to the product. If an activity step creates a form, feature, or function of value to the customer, it is called value-added; if it does not, it is referred to as non-value added.
Value Stream Mapping provides a clear understanding of the current process by:
  • Provides a visual reference for multiple process levels
  • Highlights waste and its ultimate sources
  • Brings hidden decision points into focus
A Value Stream Map is initially created using a pencil and paper outline of the process to understand the flow of materials and information needed to produce the product or service. The map should visually present the flow of a product from the customer back to the supplier. It ultimately documents the current state as well as the future state vision.
