Quality control Analyst

engineering and manufacturing, quality control and quality engineering are used in developing systems to ensure products or services are designed and produced to meet or exceed customer requirements. These systems are often developed in conjunction with other business and engineering disciplines using a cross-functional approach.Quality control is that branch of engineering and manufacturing,which deals with the assurance and failure testing in design and production of products or services,to meet or exceed customer requirements.

When the first specialized craftsmen arose manufacturing tools for others, the principle of quality control was simple: "let the buyer beware" (caveat emptor).Early civil engineering projects, however, needed to be built to specifications. For instance, the four sides of the base of the Great Pyramid of Giza are perpendicular to within 3.5 arcseconds.During the Middle Ages, guilds took the responsibility of quality control upon themselves.Royal governments purchasing material were interested in quality control as customers.

For instance, King John of England appointed a certain William Wrotham to supervise the construction and repair of ships. Some centuries later, but also in England, Samuel Pepys, Secretary to the Admiralty, appointed multiple such overseers. After World War II, the United States continued to apply the concepts of inspection and sampling to remove defective product from production lines. However, there were many individuals trying to lead U.S. industries towards a more collaborative approach to quality. Excluding the U.S., many countries' manufacturing capabilities were destroyed during the war.

This placed American business in a position where advances in the collaborative approaches to quality were essentially ignored.After World War II, the U.S. sent General Douglas MacArthur to oversee the re-building of Japan. During this time, General MacArthur invited two key individuals in the development of modern quality concepts: W. Edwards Deming and Joseph Juran. Both individuals promoted the collaborative concepts of quality to Japanese business and technical groups, and these groups utilized these concepts in the redevelopment of the Japanese economy.
