Modern Concepts Of The Six Sigma Methodology For Improving The Quality
Annals - Economy Series, 2018
Product quality is generally accepted as being crucial in today’s industrial business. The traditional aspects of product quality are connected to product design (translating customer demands into attractive features and technical specifications) and to the design and specification of high performance production processes with low defect rates. Quality management is the general expression for all actions leading to quality. Quality management is focused on improving customer satisfaction through continuous improvement of processes including the removal of uncertain activities, and continuous improvement of the quality of processes, products and services. The quality management includes four key processes, such as quality planning, quality assurance, quality control and quality costs. The main accent in this paper will be on quality control and the application of one of the quality control tools in order to improve it. Six Sigma is different from other quality improvement concepts in...

Quality Management and Six Sigma
2010
The history of quality is the history of human efforts to make things perfect in an imperfect world. The main purpose of the quality procedures is to reduce errors and increase customer satisfaction. Errors and mistakes are part of human nature, but so is the ability to create solutions and find better alternatives. By using modern quality management tools we can shift the balance from errors towards solutions and better alternatives. Six Sigma methodology represents an evolution in quality management that is being widely implemented in industry and business in the new millennium. In the mid-1980s it was developed by Motorola Inc. to reduce the cost of products and eliminate defects. Using Six Sigma methodology, Motorola Inc. become a quality leader and won the Malcolm Baldrige National Quality Award in 1988. Preface XII I hope that this book as a free resource will help to employees worldwide at all levels in different areas of business and industry, who need to improve their knowledge and experience in Six Sigma and Quality Management.

Six Sigma - A New Direction to Quality and Productivity Management
The fast changing economic conditions such as global competition, declining profit margin, customer demand for high quality product, product variety and reduced leadtime etc. had a major impact on manufacturing industries. To respond to these needs various industrial engineering and quality management strategies such as ISO 9000, Total Quality Management, Kaizen, Just-in-time manufacturing, Enterprise Resource Planning, Business Process Reengineering, Lean management etc. have been developed. A new paradigm in this area of manufacturing strategies is Six Sigma. The Six Sigma approach has been increasingly adopted world wide in the manufacturing sector in order to enhance productivity and quality performance and to make the process robust to quality variations. This paper discusses the quality and productivity improvement in a manufacturing enterprise through a case study. The paper deals with an application of Six Sigma DMAIC(Define-Measure-Analyze-Improve-Control) methodo -logy in an industry which provides a framework to identify, quantify and eliminate sources of variation in an operational process in question, to optimize the operation variables, improve and sustain performance viz. process yield with wellexecuted control plans. Six Sigma improves the process performance (process yield) of the critical operational process, leading to better utilization of resources, decreases variations & maintains consistent quality of the process output.
Total Quality Management vs. Six Sigma
Quality assurance models are an essential factor for the successful completion of all activities. There is a growing global interest in identifying quality models, both in general and in education. The purpose of this paper is to analyze the characteristic elements of total quality management (TQM). TQM represents an integrated effort meant to improve the quality of each level of the organization. The historical evolution of the total quality management comprises four steps: quality inspections, quality control, quality assurance and, finally, the TQM process itself. Quality is obvious in human actions. The goal of the Six Sigma strategy is to increase an organization's profit by eliminating variability, reducing the number of defects and eliminating losses, which removes the consumer and harms the organization. The term Six Sigma is derived from the field of statistics, because σ represents the standard deviation. This model helps organizations improve the quality of their products and services to meet customer needs. Background: Quality assurance models are effective tools at the level of institution management, in general, but also at the level of educational institutions, provided they are correctly implemented. The statistical control through inspections, the post-production effort of separating the functional and non-functional products, have led to a particular order of these steps. The selection should be carried out before beginning the development of the product. The development of control charts and the acceptance of survey methods in the period between 1924-1931 (Sthewhart and Dodge-Roming) obviously helped, during the time, the inspection related prosperity of the field. During the Second World War, system production became a complex process and, thus, quality came to be analyzed by the means of inspections; the act was carried out much more efficiently when the workers' analysis was applied. Six Sigma referred to the possibility of manufacturing processes to produce a very high proportion according to specifications. In the field of quality management, σ represents the percentage of products without defects. Materials and Methods: An analysis of representative models in terms of quality management is appropriate. The analysis of the models is based on several coordinates: identifying the characteristic elements, exploring the ways of capitalizing on the models at the level of the institution, highlighting the advantages and disadvantages. In the third step, that of quality assurance, there is a strategy analysis with the precise purpose of offering enough trust that a particular product or service satisfies the needs of the customers. The next step brought quality workbooks in which quality is achieved with average costs, and the development of the control process has the purpose of passing from the quality assurance era to that of total quality management. The level of the error-free production process in this method is determined by the number σ, which is the percentage of products without defects in percent at the exit of the process. A process with a quality of 6σ at the output characterizes 99.99966% of cases without defects or at most 3.4 defects per 1 million operations. Results: A successful model of quality in the organization's management emphasizes the relationships between internal employees, around which revolve the external influences of society, family, labor market requirements, the need for competence and lifelong learning. The model shows a set of practices which allows an organization to deliver quality products and services. The term total from the total quality management phrase highlights the fact that everybody from the organization should be involved in the efforts of continuous improvement in all of the departments. The term quality is used, in its usual meaning, while the term management refers to the system of leadership which involves planning, organizing, leading and quality assurance. The Six Sigma model has a profound impact on product quality, customer service performance and staff professional progress. It examines all processes to eliminate variations that could contribute to malfunctions or defects of the final product. The Six Sigma model is applicable to all general processes and involves all employees to lead to the necessary changes. Conclusion: Successful achievement of quality management is conditioned by compliance with clear performance criteria. These criteria are determined by different reference models in the field, such as Total Quality Management and Six Sigma. Total Quality Management (TQM) constitutes a way of leading an organization centered on quality through the participation of all of its members. Through this model, constant improvement is sought, along with the gradual introduction of the new processes, so as to obtain a higher degree of excellence in organizations. The analysis of the representative models in the field of quality led to the elaboration of a new approach for conceptualizing the quality management in close connection with the novelty
Quality Management, Total Quality Management And Six Sigma
International Journal of Scientific & Technology Research, 2019
Quality is the characteristic which distinguishes a product and service from its rivals. Quality is not the responsibility of a single member to ensuring superior quality of a service or product. TQM is a combined endeavor of management, Employees, workers and suppliers in order to get and go beyond client happiness point. PDCA cycle is major part of TQM. TQM is a joint effort of both top management and employees of a company to devise efficient policies and strategies to give good quality goods which meet and exceed customer satisfaction. Each TQM model incorporates customer feedbacks with applicable data and strategy as per the design effective plans to attain high quality goods. Few quality management tools are check list, Pareto chart, Fishbone diagram, Histogram, Scatter diagram, and graphs. Six Sigma make sure better quality of goods by eliminating the imperfections in the systems and processes. DMAIC and DMADV are two methods of Six Sigma. Kaizen is explained as a constant attempt by all employees to make sure enhancement of all system and processes of a particular company.-Five S‖ of Kaizen is a methodical approach which directs to infallible systems, standard strategies, set of laws and regulations to give rise to a strong work culture at the company. There is a vital role of managers and customers in implementing Six Sigma. Six-Sigma and TQM both are efficient tools for quality management but there exist a thin line of difference between them. Six-Sigma gives improved and efficient outcomes as compared to TQM. There are some differences in methodologies of manufacturing and service sectors.
Implementation of Six Sigma to Reduce Cost of Quality: A Case Study of Automobile Sector
In the era of cut-throat competition, especially in automobile sector, success of an organization resides in its ability to respond quickly to the needs of its customers. These customer needs must be attended with minimum manufacturing costs, minimum lead time to launch the product in market, and delivering better performance than the existing competitors in the market. Six Sigma is a powerful methodology which ultimately helps in cost reduction. Because of defect prevention and improved product and processes, it leads to increase in profitability and market share. This is accomplished through the use of two Six Sigma sub-methodologies: DMAIC and DMADV (Andersson et al., TQM Mag 18:282-296, 2006). By adopting Design For Six Sigma methodology in the design stage itself leads to launch of a product with maximum quality performance, with tighter tolerances, and with reduced or no defects. This paper considers cost of poor quality as the loss imparted to society from the time the product is shipped, and deals with the applications and benefits of Six Sigma methodology and its positive impact on cost of poor quality. A case study is presented, which enabled application of six sigma methodology in wider range of manufacturing activities. This paper is of value to the researcher in the field of quality management, as well as professionals in the manufacturing industry, wherever the quality improvement is an issue. Quality costs or Cost of Quality is a means to quantify the total cost of quality-related efforts and deficiencies (Banuelas and Antony,
