Value Stream mapping

     Value stream mapping is a method to analyse all processes in the company from the time customers place an order up to receiving the products. This method will help to identify both value adding and non-value adding processes. Once they are drawn up in a one page picture, the non-value adding processes such as lead time or waiting time can be removed, or the process required to make some parts can be arranged in a specialised work cell to reduce inventory and that waiting time between operations. In this way, the overall process can be improve and thus increased the customers' satisfaction.

This is the example of a value stream map of one of the processes in the aluminium extrusion process:
