Average Outgoing Quality Limit Explanation

Average outgoing quality (AOQ) is the quality of a batch of products after applying rectifying inspection. It is the average quality which is obtained after all the defective products are expected to be replaced with good products. It is evident from the average outgoing quality curve that when incoming material is good, outgoing quality will be good. In addition, another extreme of the AOQ curve is that when incoming material is bad, a lot of rejection takes place during inspection making the outgoing products good. In between these two extremes, there is a point on AOQ curve which shows the worst average outgoing quality for a batch of products. This point is called average outgoing quality limit (AOQL). Average outgoing quality limit gives the value of maximum percent defective in a batch or products that are to be shipped to the customers.
