If you are a CEO of a manufacturing company with many value streams, it’s impractical to think that you have the time to review all the performance measures of every value stream in your company. Yet you need to know the operational impact of lean on your entire organization.

In my first article, the merits and cautions of AS9138 c=0 sampling plans were discussed and a simple formula was provided to determine the required sample size to detect nonconforming units.

In my previous article, I discussed the merits and cautions of the “acceptance number” equal zero (c=0) sampling plans contained within AS9138. A simple formula was provided to determine appropriate sample size, and it was illustrated that twice the inspection does not provide twice the consumer protection.

Omnex began working in the automotive industry by assisting Ford powertrain suppliers in 1986. The U.S. automotive industry’s Big Three used GM’s Targets for Excellence, Ford’s Q 101, and Chrysler’s SQA standards to qualify its supply bases. The automotive industry was making deep reductions in its supply bases based on the results of these assessments and other factors. Though many on the Omnex team at that time came from General Motors, Ford’s Q 101 was the standard that really received our attention.

Aerospace standard AS9138—“Quality management systems statistical product acceptance requirements” was issued this year (2018), a few years after its accompanying guidance materials in section 3.7 of the International Aerospace Quality Group’s (IAQG) Supply Chain Management Handbook.

In this all-manufacturing episode, we look at the STEM pipeline into manufacturing, supplier development, how to make sense of manufacturing data and, no, manufacturing is not dead.

“Strengthening the STEM Workforce Pipeline Through Outreach”

Technological innovations on all fronts are evolving quickly and are developed, manufactured, and sold worldwide in aerospace, medical device, communications, automotive, and many other industry segments. It’s hard to keep up with these breakthroughs because they are growing exponentially. But despite all the technological innovations, one critical issue has persisted since the first industrial revolution during the mid-1800s: the engineering, manufacturing, and quality “interpretation” by companies’ suppliers, whether internal or external.
