The define–measure–analyze–improve–control (DMAIC) approach is a five-strata approach, namely DMAIC. This approach is the scientific approach for reducing the deviations and improving the capability levels of the manufacturing processes. The present work elaborates on DMAIC approach applied in reducing the process variations of the stub-end-hole boring operation of the manufacture of cra...

This paper first enlists the generic problems of alloy wheel machining and subsequently details on the process improvement of the identified critical-to-quality machining characteristic of A356 aluminum alloy wheel machining process. The causal factors are traced using the Ishikawa diagram and prioritization of corrective actions is done through process failure modes and effects analysis. Proce...

-Six Sigma is a systematic methodology for continuous process quality improvement and for achieving operational excellence. Six Sigma methodology is designed to provide for the application of statistical tools in the context of a process improvement structure summarized by the acronym DMAIC– Define, Measure, Analyze, Improve, and Control. The DMAIC model provides a framework to identify and eli...

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: of this paper: In the paper is presented a Six Sigma project, undertaken within company for production automotive parts, which deals with identification and reduction of production cost in the deburring process for gravity die-castings and improvement of quality level of produced parts. Design/methodology/approach: The objectives are achieved by application of Six Sigma approach to qua...

The Lean Toolkit The lean toolkit is comprised of a set of tools that are used in support of the Six Sigma DMAIC process, which is an acronym for define, measure, analyze, improve, and control (Figure 1). While this toolkit is not all inclusive, the set of tools that will be discussed over my next few columns will allow an organization to move through each of the DMAIC functions and facilitate ...

The improvement process of six-sigma DMAIC refers to the that industry performs enhance quality via following five procedures: (1) define, (2) measure, (3) analyze, (4) improve, and (5) control. It is a common tool used in ameliorate quality. In addition, capability index most frequently uses measure Though many studies have discussed methods, none specific theoretical models could be provided ...

OBJECTIVE Teaching quality improvement (QI) is a priority for residency and fellowship training programs. However, many medical trainees have had little exposure to QI methods. The purpose of this study is to review a rigorous and simple QI methodology (define, measure, analyze, improve, and control [DMAIC]) and demonstrate its use in a fellow-driven QI project aimed at reducing the number of d...
