his quote is still very much prevalent today and can be applied to all companies, especially those that must continuously improve the quality of their product, especially in the fast-paced technological society we live in today. How has quality control evolved over time and what will it look like in the future?
History of Quality Control Before the early 20th century, the principal focus of mass production was focused on quantity, rather than quality. During this time, quality control was a means of improving upon the machinery and technology to increase productivity while using less human energy. However, by the 1920s, the focus shifted from quantity to quality of the product due to an increase in demand. There was an increase in emphasis to ensure that quality was consistent. Manufacturers required cheaper and more efficient work in order to increase output per machine, per person per hour. It became clear that working longer and harder did not produce maximum efficiency. This understanding demonstrated that working smarter and employing quality control measurements was the way to yield the most profits. Today, there are two important
quality assurance methods that is used in a wide variety of industries that produce products: Six Sigma and Lean Manufacturing. Both methods are aimed at reducing waste and creating efficient processes, but they take a different approach on how to accomplish this. The goal of six sigma is to reduce
variation and defect rates in production processes through statistical analysis. Essentially, six sigma uses two Figure 3: Lean Manufacturing
