CASE: VALUE STREAM MAPPING APPROACH
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 12.14
, 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 12.15
shows the future state map with production lead time of 0.25 day. This was accomplished by moving to a continuous-flow pull system and attacking the seven wastes. VSM uses a number of special icons and display format of boxes and flows. For a more complete discussion of the methodology, see Jared Lovelle.

QUESTIONS
1. Eliminating the queue of work dramatically quickens the time it takes a part to flow through the system. What are the disadvantages of removing those queues?
2. How do you think the machine operators would react to the change?
3. What would you do to ensure that the operators were kept busy?
