Value Stream Mapping
is a technique that established as a common language to document process and
provides a blueprint for improvement. There are some states in this technique,
the first state called as current state, the next state called as future state.
Current state map is drawn by a cross functional, multi
discipline team to document how things actually operate. In this state can be
seen the differentiation between how things should be done and the actual
process. Future state map is developed to design a lean process flow through
the elimination of the root causes of waste and through process improvements –
all leading to an Implementation Plan that details the action steps needed to
support the objectives.
The key elements of the Value Stream are documented on
the map in an established sequence:
1.
The customer and their requirements
2.
Main process steps
3.
Process Metrics (process time, wait time, first
time quality)
4.
Supplier with material flows
5.
Information and physical flows
6.
Overall performance of the value stream
Many obvious parallels exist between Value Stream
Mapping and the Value Methodology, including the few mentioned previously.
VM is about building value for the customer by improving performance (or function) while reducing life-cycle cost,
VSM is about building value for the customer by eliminating waste and non-value added
work. There are also key similarities of purpose between VSM and VM, such as starting with – and
maintaining – a focus on the customer and getting the right people involved in a creative
process.
The Value Methodology is very much about balance – in
improving performance while reducing (total) cost while satisfying the customer. Value Stream Mapping works to strike a
balance as well and uses a similar structured approach that bears a striking
resemblance to VM.
