Value Stream Mapping

Value Stream Mapping (VSM) is a Six Sigma method used to align the process with customer demand (takt time). Optimization potentials are derived from the VSM.

Procedure:

VSM = Value Stream Management

All process steps required to produce the final product from raw materials are recorded. The material flow is considered backward, from the customer to the supplier. Through simple visualization, you can quickly see the most important aspects of your manufacturing process. The value stream design is developed from the value stream analysis as a vision.

Delivery time depends on customer demand (500 pieces/day). For example, if the inventory is 1500 pieces, the lead time must be 1500 pieces / 500 pieces = 3 days.
