Quality control is a methodology employed in manufacturing to prevent defects in manufactured products. Abbreviated as QC, the method has been implemented in a number of ways each of which has its own name and following. Quality control is typically associated with statistical approaches. Quality management has strong philosophical aspects based on the insight that quality is as much the result of management approaches as it is of specific activities. The modern quality movement is a fusion of American know-how originally developed at Bell Laboratories and Japanese enterprise and implementation. The several waves of quality control methods that have swept U.S. manufacturing since the 1950s are almost unthinkable except against the backdrop of Japanese industry achieving a world class reputation and thus producing stimulus. The movement is very closely associated with an American mathematician and physicist, W. Edwards Deming, although Deming was one of two prominent individuals who helped the Japanese forge their approaches to manufacturing; the other was Joseph M. Juran, a Rumanian immigrant to the United States. America's embrace of QC followed its successful application in Japan. Some type of statistical quality control is practiced in connection with most demanding manufacturing processes, but the more "qualitative" (no pun intended) aspects of QC have never been wholeheartedly embraced.
Modern quality control originated with Walter A. Shewhart, then working at Bell Telephone Laboratories. Shewhart devised a control chart named after him in 1923 and in 1931 published his method in Economic Control of Quality of Manufactured Product. Shewhart's method saw its introduction at Western Electric Company's Hawthorn plant in 1926. Joseph Juran was one of the people trained in the technique. In 1928 he wrote a pamphlet entitled Statistical Methods Applied to Manufacturing Problems which was later incorporated into the AT&T Statistical Quality Control Handbook which is still in print. In 1951 Juran published his very influential Quality Control Handbook.
Before the advent of statistical quality control, control was exercised by inspecting the output of manufacturing processes and removing defective items. The modern technique established an upstream method for detecting deviations from specified quality—early detection—used to trigger analysis of causes and then changes to manufacturing procedures.
Statistical quality control, as described above, is the fundamental description of quality control in the modern context. It is centered on measuring deviations from a norm and then taking actions to eliminate such deviations. But quality control, almost from the outset, came to be surrounded by what might be called a "cultural" radiation—namely management approaches, philosophies, and practices aimed at creating the right environment for a quality-driven industrial process. These radiations in part came from Japanese management culture, very different from U.S. practice, the ideas of Deming—which both influenced and reflected Japanese practice—and their elaborations by others.
Quality control in the modern sense has come a long way since its initial formulation in the 1920s and its widespread adaptation in the 1950s, first in Japan, then across the world. It has become a routine part of many manufacturing processes, and, as signaled by Six Sigma, the goals are becoming ever-more ambitious. The more managerial and people-oriented aspects of the quality movement have a spottier history and have produced a series of initiatives that have come, have gone, and have resurfaced in various guises. Ever-new labels indicate attempts to capture something evidently difficult to hold for long: "quality circles," "teaming," the "learning organization," "knowledge management," "empowerment," and the like. The social phenomenon appears to indicate that it is ultimately easier to produce defect-free gadgets than perfect humans. The difficult we'll do immediately; the impossible will take a little time.
TQM is a philosophy of management in which the operational elements are continuous quality improvement, quality circles, and strong management backing.
Having quality control in place within a business can only help ensure product quality and the overall success of a business. The environment of quality control influences employees' attitudes about the workplace and creates a sense of ownership in the products and company as a whole. Quality control can be done in various ways, from training personnel to creating data-driven tools to test products and set standards. Quality control methods help create a safe work environment and product safety that benefits customers and the company alike.
In food and drug manufacturing, quality control includes ensuring the product does not make a consumer sick, so the company performs chemical and microbiological testing of samples from the production line .
The purpose of the testing is to determine any needs for corrective actions in the manufacturing process. Good quality control helps companies meet consumer demands for better products. Quality testing involves each step of the manufacturing process.
A quality control chart is a graphic that depicts whether sampled products or processes are meeting their intended specifications—and, if not, the degree by which they vary from those specifications. When each chart analyzes a specific attribute of the product, it is called a univariate chart.
Implementing quality control procedures ensures you are selling the best products to your customers. In addition, practicing quality control has a positive impact on employee conduct. Quality control can inspire employees to create high-quality goods leading to greater customer satisfaction.
Quality control (QC) is a process through which a business seeks to ensure that product quality is maintained or improved. Quality control involves testing units and determining if they are within the specifications for the final product. The quality control used in a business is highly dependent on the product or industry, ...
Testing at the various stages of manufacturing helps identify where a production problem is occurring and the remedial steps it requires to prevent it in the future.
Quality control inspectors examine products and materials for defects or deviations from manufacturer or industry specifications. They ensure that your food will not make you sick, that your car will run properly, and that your pants will not split the first time you wear them.
Quality control workers rely on a number of tools to do their job. Although some still use hand-held measurement devices, such as calipers and alignment gauges, they more commonly operate electronic inspection equipment, such as coordinate-measuring machines (CMMs). Inspectors testing electrical devices may use voltmeters, ammeters, ...
Although most quality control inspectors work full time during regular business hours, some inspectors work evenings or weekends. The most desirable shifts are generally given to workers who have seniority.
Inspectors testing electrical devices may use voltmeters, ammeters, and ohmmeters to test potential difference, current flow, and resistance, respectively. Quality control workers record the results of their inspections and prepare test reports.
Quality control analysts are specialists who ensure that a company’s products and the materials used in manufacturing them meet the required standards. They test materials and finished goods to ensure that they meet production standards and might reject items not meeting standards. They work with manufacturing companies, pharmaceuticals, ...
