JIT also eliminates waste and/or decreases work in progress (WIP) in that same sense. JIT allows for products that are produced to fulfill an immediate demand for them. JIT emphasizes on quality.

In a worker paced line flow, the process of making raw material into a finished product is increasingly fast, such as in a fast food restaurant. The customers expect to be served
