Homework 8 SCM
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.
The diagram above shows the current state with production lead time of 4.5 days. This system is a batch/push system (indicated by stripped arrows) resulting in long delays and inventory buildups.
The diagram below also shows the future state map with a production lead time of 0.25day.
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 of boxes and flows.
Question?
1) Eliminating the queue of work dramatically quickens the time it takes to flow through the system. What are the disadvantages of removing those queues?
2) How do you think machine operators would react to the change?
3) What would you do to ensure that the operators were kept busy?
4) Stopping waste is a vital part of lean. Using value stream mapping, identify some sources of waste in your home or dorm and discuss how they may be eliminated.
5) Discuss ways t use lean to improve one of the following: a pizza restaurant, a hospital, or an auto dealership.
