Reducing Work in Progress Inventory in a Valve Industry Using Value Stream Mapping

In this paper Value Stream Mapping (VSM) tool is used in valve manufacturing industry by focusing both on processes and their cycle times for a product 3/4 bonnet valve. In order to use the value stream mapping, relevant data has been collected and analyzed. After collecting the data customer need was identified. Current state map was draw by defining the resources and activities needed to manufacture, deliver the product. The study of current state map shows the areas for improvement and identifying the different types of wastes. In this Process (current state) it is noticeable that it is a batch flow and WIP is in the form of machine availability and customer demand time.
