Question 5

Which of the following most accurately describes the role of quality in a lean/just-in-time manufacturing environment?

Accepted Answer

A) High quality is an important waste reduction tool. Reducing defects reduces wasted material and capacity, and reduces the need for safety stocks. 
B) Quality has little to do with JIT. JIT is primarily a scheduling and inventory control tool. 
C) The important thing is to screen the defects out of incoming components and raw materials. If this is done, the production process can carry on without much concern for quality. 
D) Because everything is being done just in time, there is no time to worry about quality during the production process. Instead, we rely on screening out defects during finished goods inspection.
