Reputation is the primary stuff of perceived quality. Its power comes from an unstated analogy: that the quality of products today is similar to the quality of products of yesterday, or the quality of goods in a new product line is similar to the quality of a company's established products. [4]
Quality control (QC) is implemented as a means of fulfilling quality requirements, reviewing all factors involved in production. The business confirms that the good or service produced meets organizational goals, often using tools such as operational auditing and inspection. QC is focused on process output.
Quality is the ability of a product or service to meet and exceed customer expectations. It is the result of the efficiency of the entire production process formed of people, material, and machinery. Customer requirements determine the quality scope. Quality is a competitive advantage; poor quality often
Six Sigma (6σ) is a set of techniques and tools for process improvement.It was introduced by American engineer Bill Smith while working at Motorola in 1986. [1] [2]Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.
Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology.
The plan–do–check–act cycle is an example of a continual improvement process. The PDCA (plan, do, check, act) or (plan, do, check, adjust) cycle supports continuous improvement and kaizen. It provides a process for improvement which can be used since the early design (planning) stage of any process, system, product or service.
Management of quality was the responsibility of the Quality department and was implemented by Inspection of product output to 'catch' defects. Application of statistical control came later as a result of World War production methods, which were advanced by the work done of W. Edwards Deming , a statistician , after whom the Deming Prize for ...
Taguchi realized that the best opportunity to eliminate variation of the final product quality is during the design of a product and its manufacturing process. Consequently, he developed a strategy for quality engineering that can be used in both contexts. The process has three stages: System design; Parameter (measure) design; Tolerance design
