Procedures and checks can only take your quality improvements so far.
To maximize your quality, you need to design quality feedback loops.
Manufacturing companies are continually pursuing quality improvements, and with good reason. Improved quality not only increases productivity and profit as non-conformances and scrap are reduced, ensuring the shop floor is focused on product that ships, but also aids in sales. Consumers buying a product don’t care about productivity and efficiency; they care about value and quality - manufacturing quality.
