Six Sigma has been considered a powerful business strategy that employs a wellstructured continuous improvement methodology to reduce process variability and drive out waste within the business processes using effective application of statistical tools and techniques. Although there is a wider acceptance of Six Sigma in many organizations today, there appears to be virtually no in-depth case st...

the aim followed in tillage operations is the preparation of a suitable seedbed. the clod mean weight diameter (mwd) is one of the important tillage quality factors. in this study six sigma methodology was employed to improve the mwd index on the experimental farm of the university of tehran. six sigma is considered as one of the new improving process methods that has gained wide applications i...

Globalization, advancement of technologies, and increment in the demand of the customer change the way of doing business in the companies. To overcome these barriers, the six-sigma define–measure–analyze–improve–control (DMAIC) method is most popular and useful. This method helps to trim down the wastes and generating the potential ways of improvement in the process as well as service industrie...

Purpose – The purpose of this paper is to critically evaluate the contributions of six sigma methodology to the improvement of service quality. Since its development in the late 1980s, six sigma has been extensively applied in manufacturing and quasi-manufacturing settings. This study aims to explore the challenges of six sigma in reaching a much wider field of application. Design/methodology/a...

The six-sigma systems can promote the enterprise competitive ability, such as pursuing cost improvement, promoting quality, the customer’s satisfaction and valid strategy performance. This paper explored the synergies resulting from the combination of state-of-the art quality initiatives, lean and design for Six Sigma, and develop an integrated SCOR with lean and design for Six Sigma methodolog...

The six sigma methodology aims to reduce the number of mistakes/defects in a manufacturing process and hence the manufacturing costs. Six sigma is the ultimate measure of quality. As firms improve their processes, and move towards the elusive six sigma, they often need to re-design the products, process and services to ’’designout’’ defects and design-in quality. Describes the underlying statis...

While Six Sigma is increasingly implemented in industry, little academic research has been done on Six Sigma and its influence on quality management theory and application. There is a criticism that Six Sigma simply puts traditional quality management practices in a new package. To investigate this issue and the role of Six Sigma in quality management, this study reviewed both the traditional q...
