24. Process Control – Value Stream Mapping
Value Stream Mapping (VSM) is generally used to illustrate product realization processes starting from raw material to the phase where the final goods are delivered to customers. Value stream map also ensures the detailed steps are breaking down to a sequence of flow of information and resource within the process.
The following table consists of the differences between process map and value stream map.

In conclusion, the core elements in the VSM should have the following items:
- Costumer focused (end to end process)
- Helps to visualize process flow (starts, stops and idle time)
- Identify potential waste and resource allocation.
- Have the current and future process maps step by step.
- Information separated with process physical flow (yield, operators qty, cycle time, downtime…etc.)
