The Value Stream
The flow of work involved in turning an idea into a product that can be consumed by the customer.
Value Stream Mapping
Value stream mapping is a lean enterprise technique used to document, analyze and improve the flow of information or materials required to produce a product or service for a customer.
Current State – clarify, follow the work, map and assess
Future State – create and work toward
Why map the value stream?
- See and understand the whole process (value stream)
- Optimize entire stream instead of just your own section of the stream
- Agreement on current state
- Agreement on what the future state should look like – a shared focus on continuous improvement effort
Mapping the Value Stream
- Identify the actions taken in the value stream
- Calculate the calendar time for each action
- Calculate actual time worked on the action
- Identify the time between actions
- Identify any loop backs required
- Calculate the Process Cycle Efficiency/Metrics
