The Juran and Deming philosophy and the six sigma approach comparisonThe various quality approaches and systems are the Deming philosophy, the Juran approach, six sigma and other approaches. We can say that philosophies like these, can be the most important part of the companies success. We know now that quality needs to be built into every level of a company, and become part of everything the organization does.Firstly we need to mention that Deming and Juran were the two inventors of the quality and both of them said that all processes like planning, organizing and controlling steps should be done by the leader of the company. On the other hand, Deming and Juran have their own theories, in which Juran specified that quality must be in the product; in contrast Deming said that quality must be in the process, where it will be in the product or in the service. Joseph Moses Juran was a Romanian-born American engineer and management consultant. He was a charismatic figure, acknowledged world-wide for his extensive contribution to quality management. While often referred to as one of the leading figures of total quality management, much of Jurans work actually preceded the total quality concept. He became a legend in his own time, and has been instrumental in shaping many of our current ideas about quality.The Juran philosophy is based upon the companys current strategic planning and minimum risk in rejections. His insight was in quality management that different employees at different levels of the organization hold different factors as priority. He stated that the top management takes money as important, workers takes things as important and mid management takes money and things at the same time as important. The system of quality management and improvement is best summarized in his trilogy, based on the three quality management processes of quality planning, quality control and quality improvement.
Quality planning: We have to identify who the customers are, we have to measure the needs of those customers and understand those needs. We have to optimize everything so the company needs can meet whit customer needs.Quality control: We have to develop a process, which is able to produce the product and of course optimize the process.Quality improvement : Prove that the process can produce the product. His concept in quality management was the relationship between the process and functions of manufacturing and control of the whole process. His insight was that feedbacks and testing and the whole quality system should have no end and it has to be continuous.William Edwards Deming was an American engineer, statistician, professor, author, lecturer, and management consultant. Educated initially as an electrical engineer and later specializing in mathematical physics. Deming’s work not so technique like a philosophy of management. The key to Demings ideas on quality appears in his remark of the importance of variation. It means that improving the products and services by reducing the uncertainty and variability in the design and manufacturing process. For poor quality variation can be responsible. We have to mention here variation in manufacturing can be the reason of failure.  Better quality leads to less rework, fewer delays and better use of factor inputs. It includes knowledge consisting of four stages -appreciation for a system, some knowledge of theory of variation, theory of knowledge and psychology. Deming had 14 points, which are really important, in connection with these four aspects. These 14 points which provide a framework to developing knowledge in the workplace and can be used to guide long term business plans and aims. Walter Shewhart originated the concept of the PDCA cycle and introduced it to Deming. Deming promoted the idea widely in the 1950s. The PCDA (plan-do-check-act) cycle has four stages. If we want to face with the problems and after that solve them, we have to be gone through these steps. Plan for changes to bring about improvement. Do changes on a small scale first to trial them. Check to see if changes are working and to investigate selected processes. Act to get the greatest benefit from changes.
