Value Stream Mapping (VSM)

Value Stream Mapping (VSM) originally came from the Toyota Production System (TPS) where it is known as “material and information flow mapping” and is the defacto current state mapping method for lean design (product and service based).

When to use it?

Use VSM for process mapping that is low variability AND high volume. In my experience it is the high volume that is the more important of the two. If you have low variability in a process but the volume is quite low the value from doing a VSM and Kaizen event is greatly diminished.

When NOT to use it?
  • In disjointed product development processes
  • Where there is no “product” to follow
  • Where there is high variety/low volume
