A value stream is the complete sequence of activities required to be performed in order to produce and deliver the end product or service. It encompasses the suppliers, internal processes, Customers and end-users.
The goal of Value Stream Mapping is to identify the primary process steps and activities that require process improvement. There are three process steps associated with VSM: the current state (what the process really is), the future state (what you want the process to be) and the initial action plan devised to close the gap between the two.
