The value stream mapping (VSM) is a tool created by the lean production movement for
redesigning the productive systems. Since, it was theoretically developed, some cases have been
published where the mentioned tool has been used; however, there is a need to see how it is put into

productive system of a manufacture for plastic casings for mobile phones has carried out this
application
