Quality Inspections are mandatory, but they don’t add real value to your manufacturing processes. The good news is: You can minimize their disruptive impact.

Under most circumstances, ANSI/ASQ Z1.4’s sampling plans (formerly MIL-STD-105s) do minimize attribute (good/bad) inspections by quickly rejecting bad lots and accepting good ones. But there is a way to reduce inspections even further.

Join William A. Levinson, a productivity systems pro, as he reveals the benefits of a zero acceptance sampling plan—which you can implement using a corresponding ANSI/ASQ Z1.4 plan once you’re confident in the high quality of your process results. Levinson shows you how to set low acceptable quality levels to assure customers that the zero acceptance plan’s protection against poor quality is at least as good as what the original ANSI/ASQ Z1.4 plan would have allowed.

Levinson will explain how to: use the ANSI/ASQ Z1.4 tables and switching rules, convert any ANSI/ASQ Z1.4 plan to a zero acceptance plan, and present the customer with an operating characteristic (OC) curve that demonstrates the level of quality protection is equal to that of the traditional ANSI/ASQ Z1.4 plan.

Unfamiliar with ANSI/ASQ Z1.4? Don’t worry: Levinson knows this field inside and out and will teach you everything you need to know to apply the standard.

Session Highlights:

  • How to use ANSI/ASQ Z1.4's tables and switching rules, which are a mandatory element of the standard
  • How to convert any ANSI/ASQ Z1.4 plan into a zero acceptance number plan that gives the customer equivalent or superior protection against poor quality.
  • How to present the customer with an operating characteristic (OC) curve that assures the customer that the zero acceptance number plan provides protection against poor quality that is at least equal to that of the traditional ANSI/ASQ Z1.4 plan.
  • Plus: Attendees will receive a PDF file that includes the full presentation notes—as well as an Excel spreadsheet that calculates OC curves for an ANSI/ASQ Z1.4 sampling plan and the corresponding zero acceptance number plan
