Purpose The purpose of this paper is to study the anodising process of a portable amplifier production process to identify and eliminate the sources of variations, in order to improve the process productivity. Design/methodology/approach The study employs the define-measure-analyse-improve-control (DMAIC) Six Sigma methodology. Within the DMAIC framework various tools of quality management such as SIPOC analysis, cause and effect diagram, current reality tree, etc., are used in different stages. Findings High rejection rate was found to be the main problem leading to lower productivity of the process. Four types of defects were identified as main cause of rejections in the baseline process. Pareto analysis resulted in detection of the top defects, which were then analysed in details to find the root cause of the problem. Further study resulted in finding improvement measures that were discussed with the management before implementation. The process is sampled again to check the improvements, and control measures were established. Practical implications The study provides a framework for implementation of DMAIC Six Sigma methodology for a manufacturing firm. The results presented are based on the data collected from the shop floor. Results and findings of the study were implemented for quality improvement of the process. Originality/value The study is based on an original research conducted with the objective of quality improvement in the anodising process of the production process. Besides presenting an approach to DMAIC Six Sigma methodology, an application of the current reality tree tool for root cause analysis is presented, a tool used limitedly in the Six Sigma studies. The tool finds its uniqueness in its ability to address problems relating multiple factors than isolated factors.

Six Sigma Approach

Purpose This paper is one of seven in this volume that aims to elaborate different approaches to quality improvement in education. It delineates a methodology called Six Sigma. Design/methodology/approach The paper presents the origins, theoretical foundations, core principles and a case study demonstrating an application of Six Sigma in a school-community partnership in Milwaukee, Wisconsin. Findings The core principles underlying the approach are decreasing variability or unreliability in organizational work processes, eliminate waste or activity that does not add value to desired outcomes, identify defects and decrease their incidence, reduce the cost of work processes, and improve beneficiary/client satisfaction levels. The steps in this statistics-dependent method are design, measure, analyze, improve and control. Originality/value Few theoretical treatments and demonstration cases are currently available on commonly used models of quality improvement that might have potential value in improving education systems internationally. This paper fills this gap by elucidating one promising approach. The paper also derives value as it permits a comparison of the Six Sigma approach with other quality improvement approaches treated in this volume.

Six Sigma Approach

The successful implementation of the six sigma quality improvement program is demonstrated through the improvement of the capability process in producing products leading to zero defect. Therefore, the concept of calculating process capability is very important to understand in the implementation of the Six Sigma program. This research raises the problem of the low level of capability process in producing yarns at PT. Sutra Cotton Textile Industries, Surabaya. By wisely applying six sigma techniques can help reduce things that can affect overall costs. If a company has successfully implemented the concepts in six sigma, then it can be ascertained that the company is truly a reliable company in the world class. Another advantage gained from the implementation of the Six Sigma program is the achievement of targets, namely the increased capability process, of course, in terms of cost. From secondary data in May 2019, in the measure phase it is known that the DPMO value of 16,266 which can be interpreted that of one million production carried out there was a defect of 16,266 with a sigma value of 3.64. From these results it can be said that the production process in Winding has not been able to produce products that fit the desired specifications and is still lagging behind other subprocesses. method. The main priority in carrying out corrective actions based on FMEA is to clean and check the machine at the end of each production cycle. From the results of improvements, the sigma value and DPMO value obtained in September 2019 is 10,977 DPMO which means that of one million production carried out there is a defect of 10,977 with a sigma value of 3.80.

PurposeThe purpose of this paper is to capture the evolution and status of utilization of the Six Sigma philosophy in the development of small to medium‐sized enterprises (SMEs), as well as to document prominent development of practices through a systematic literature review.Design/methodology/approachThe methodology adopted for this study used the principles of content analysis and deductive reasoning vis‐à‐vis various sub domains of Six Sigma methodology pertaining to industries in general and SMEs in particular.FindingsThe literature revealed that: Management's commitment is most important in SME Six sigma implementation. Benefits of Six Sigma have been enjoyed largely by the bigger industrial units and to a relatively lesser extent by the smaller units, i.e. SMEs. Quality management culture has largely been ignored or given less importance in the SME sector, which is evident from the meagre literature. There is a dearth of clear and SME‐specific methodologies (for Six Sigma approach) for quality improvement and there are far fewer models for quality improvement in the SME sector.Originality/valueIt has been found, on the basis of a systematic literature review approach (used in this paper), that quality management and development in SMEs needs to be done in a planned manner using Six Sigma roadmap.

Six Sigma Approach

Quality has become a competitive weapon in both the manufacturing and the service sector. And from past few decades, service sector particularly education sector has been neglected in terms of quality improvement efforts or we can say that quality improvement strategies are not being implemented in the education sector. Day by day the number of educational institutes is increasing and most of them are being managed by private management. As profitability is their major concern, therefore the aspect of quality is being overlooked. Today the higher educational Institutions are exposed with global competition and facing a lot of problems such as low graduation rates, higher drop-out rate, less employability etc. Therefore educational organizations must adapt six sigma methodologies to improve the quality of higher education. Although the method of applying statistical process control in education industry is really challenging but in this thesis we take a primary step to search out a solution for the education sector so that they can improve the quality of higher  education.
