Value Stream Improvement
Value stream is all steps, value-added and non-value added, that are required to bring a product from raw material to the customer.

Value Stream Mapping
Walk a product’s production path from beginning to end, and draw a visual representation of every transportation, storage, and overall product process in the material and information flows.
Then draw, using the VSM icons, a “future state” map of how value should flow.

Future State Map
Purpose is to identify and eliminate sources of waste. Key Questions: How will you level the flow? What is the increment of work that will consistently be
released and taken from the ‘pacemaker’ process? What process improvements will be necessary for the value
stream to flow as your design state specifies? What is the increment of work that will consistently be
released and taken from the pacemaker process?

Macro Value Stream Mapping
Extends beyond plant level maps
Reasons:
Large portion of costs consist of purchased materials
Costs downstream can negate cost savings internally
Major asset reconfigurations can be identified by showing who does what where
