Value Stream Mapping

View all resources for this topic

Value stream mapping is a technique used to sequence all the process tasks required to transform a product from raw material to a complete, deliverable customer item. It highlights where value is added and areas where no value (waste) occurs and can be used as method to identify any inefficiencies in the process that need addressing.

A value stream map itself is a sequence of activities to produce an end product or deliver a service. 

By understanding these steps it is then easier to understand how improvements to the system might be made by streamlining or removing certain steps. A value stream map which has been improved but not implemented is known as a future state map.
