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 ...

-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...

The DMAIC (Define-Measure-Analyze-Improve-Control) method in Six Sigma is often described as an approach for problem solving. This paper compares critically the DMAIC method with insights from scientific theories in the field of problem solving. As a single authoritative account of the DMAIC method does not exist, the study uses a large number of sources, consisting of prescriptive accounts of ...

The paper is related to the thread manufacturing process. This work clearly identified the different problems occurring during manufacturing. In the last process (winding), DMAIC tool is applied. The reason for choosing this work is to provide a better analysis of different processes in thread manufacturing. This textile firm has large departments where the thread produced from the waste clothe...

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...

Continuous process improvement is a constant preoccupation of companies operating in strong competitive markets (Thawani, 2002; Cronemyr, 2007). The goal of process improvement projects is about increasing both efficiency and effectiveness of the business system (Brad, 2008). A widely used methodology for process improvement is Six Sigma DMAIC (Cascini et al., 2008; Hamza, 2008). Some researche...

The present work deals with application of DMAIC for minimization of sand casting defects in a process industry. DMAIC approach is justified when root cause of defect is not traceable. At present, global and competitive environment, foundary industries need to perform efficiently with minimum number of rejection in their manufacturing products. For better improvement in the casting quality, fir...

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...

This article presents a process improvement study applied at a local paper manufacturing company based on customized Lean Six Sigma methodologies. More specifically, the DMAIC (Define, Measure, Analyze, Improve, and Control) project management methodology and various lean tools are utilized to streamline processes and enhance productivity. Two performance measures namely production rate and Ove...

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...
