Case: Value Stream Mapping Value Stream mapping involves first developing a baseline map of the current situation of a company's external and/or internal operations, and then applying lean concepts, developing a future state map that shows improved operations. Exhibit 14.16, for example, shows the current state with a production lead time of 4.5 days. This system is a batch/push system (indicated by striped arrows) resulting in long delays and inventory buildups. Exhibit 14.17 shows the future state map with a production lead time of 0.25 day. This was accomplished by moving to a continuous- flow pull system and attacking the seven wastes. Value stream mapping uses a number of special icons and a display format of boxes and flows.
Why is 'one piece' flow desirable within an operation?
