Question 10

The value stream mapping tool often requires completion of the future state drawing before the current state drawing, to help managers see the future state goals and more easily identify problems with the current state of the process.

Accepted Answer

Value Stream Mapping typically starts with mapping the current state to understand and visualize the existing processes and identify areas of waste before designing the future state map that outlines improvements and more efficient processes.

Question 12

Champion Cooling Company uses a kanban system at their two locations in the Oklahoma City Metroplex. The daily demand for fans is 2,000 at each location and management insists on using the same alpha level (0.1) at both locations. Location Reno uses containers that hold 20 items and takes 0.04 of a day to process a container. It takes 0.07 of a day to get a container filled and for it to wait during its cycle. Location Western uses containers that hold 24 items and takes 0.02 of a day to process a container. It takes 0.08 of a day to get a container filled and for it to wait during its cycle. Which location has the higher level of inventory? Assume that both locations round up to the next highest integer number of containers.

Accepted Answer

Question 13

A value stream map shows the flows of materials and information and the lines of responsibility and authority.

Accepted Answer

A value stream map primarily shows the flow of materials and information as they make their way through the process, but it does not explicitly show lines of responsibility and authority.

Question 14

Use of value stream mapping requires construction of a current state drawing, a future state drawing, and an implementation plan.

Accepted Answer

Value stream mapping is a lean management tool used to analyze and improve the flow of materials, people, and information through a process or system. The process of value stream mapping typically involves constructing a current state drawing to show the existing process, a future state drawing to show the desired future process, and an implementation plan to outline the steps needed to achieve the future state. Therefore, the statement is true.
