Mistake-Proofing for Perfect Quality

Until now, it could take years for a company to develop skill in mistake-proofing. Mistaking Proofing for Perfect Quality reverses that and makes perfect quality teachable and implementable in your enterprise.

Now learn how to permanently eliminate defects from design and production through our poka-yoke pathway: Mistaking Proofing for Perfect Quality (MP).

This comprehensive eight-module course was co-developed by leading experts, Dr. Martin Hinckley (author of Make No Mistake) and Dr. Gwendolyn Galsworth (author of Smart Simple Design and Work That Makes Sense).

In it, you and your teams learn how to eliminate defects permanently through mistake-proofing—from concept to consumer, from design to operations. Watch your design and process teams grow stronger, more aligned, and more effective. Watch your quality soar!

Contrary to popular notions, variation is not the source of defects—mistakes are. Complexity is. Rely on statistical process control, and you will be disappointed. The key to perfect product and process quality is SMS: Simplify, Mistake-proof, and Set Settings. It’s time to rethink your approach because quality can not only be free: It can pay back.

Until now, it could take years for a company to develop skill in mistake-proofing. Even then, what you learned usually endorsed out-of-date concepts and tools that were as hard to recall as to apply—and never addressed the real problem. Mistaking Proofing for Perfect Quality reverses that and makes perfect quality teachable and implementable in your enterprise.

Arrange for Dr. Hinckley to teach this course, on-site. He can also train your trainers, or your company can do it through our online training system.

"This is the best training I've ever attended in my life."
