The future stream map is a method of showing the desired achieved future goals. It also shows
service delivery processes after using lean tools to improve it. The future stream map is similar to
the current stream map, where both give visual representation of the material, information and time
flow, and it is used to show the level of successes and changes. The future stream map will be used
to demonstrate how the product flows, eliminating all the wastes shown in the current state and
achieve lean manufacturing. It is a powerful tool, it provides a clear statement of a vision for where
the organization is going, however if the ideas are not implemented within a short time, it will lose
its force and it will become another "has been" of manufacturing technique. The future stream map
(or VSM) in this case study, which represents the future vision of the ED, is shown in Figure 9.
The results achieved in the future stream map resulted from using some of the lean manufacturing;
these techniques are helping the ED to be more productive, flexible, smooth and with high quality
output. This will enhance the ED overall performance, lead time, changeover time and the delivery
time to patients. It can be seen that the lead time of the service at ED has been reduced from 193 sec
to 153 sec (20.7%).
