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.

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.

Opening Process

Purpose This study aims to expand the current knowledge of the Six Sigma approach in a period of time when there is little direct evidence of the need to improve the credit card account opening process. This is an important but neglected area of focus in the Six Sigma literature. This study explores the extent to which process improvement practices are extended to the credit card department. Design/methodology/approach A case study methodology is adopted in this study to facilitate an exploration of the implemented Six Sigma approach in the credit card department of a leading commercial bank. The process improvement tool used is the define, measure, analyze, improve and control (DMAIC) cycle. Findings The study’s results confirm that the Six Sigma approach improves the quality of the credit card account opening process. So, the Six Sigma approach can account for a reduced number of keying-in errors, resulting in better data accuracy and improved customer satisfaction. Research limitations/implications The authors, in an attempt to render the study results more feasible for data collection, have chosen to focus on the process of the new accounts unit of the credit card department. Therefore, the authors have not taken into account the other units (e.g. transaction processing) of the same department. Practical implications The results of this study will be useful in persuading bank management to evaluate and implement the Six Sigma approach. Hence, this research will assist bank managers with replies to questions, such as: “What impact will Six Sigma have on process-centric improvement, such as the new accounts opening process of a credit card department?” Originality/value Within the literature on the Six Sigma practice, there is little research that focuses on the implementation of this particular toolset especially for credit card departments. This indicates a gap in the field. A new contribution to bridging that gap comes from the analysis of the results for the Six Sigma concept, which addresses the new accounts opening process.

Six Sigma Methodology

Purpose In recent times, the idea of taking advantage of the benefits of simulation techniques and Six Sigma discipline altogether has led various organizations towards implementation of simulation tools within Six Sigma methodology. The purpose of this study is to provide a more comprehensive literature review on the topic exploring how this amalgamation could work both in theory and practice. This precisely entailed finding dependable studies that shows how Six Sigma (DMAIC) Methodology can be enhanced by the three prevalent simulation techniques; Agent-Based (AB), Discrete-Events (DE), System Dynamics (SD). Design/methodology/approach A systematic literature review was considered more fitting in research because it involves rigorous and well-defined approach compared to other forms of literature review. In this case, the literature was comprehensive, well-encompassing and involved finding Six Sigma and Simulations literatures from reputable scholarly databases. The outcome of these reviews was the identification of a set of key finding compiled and classified by topics. The study follows an inductive approach and utilises a meta-synthesis review technique. Findings As numerous studies assert, simulation techniques including AB, DE and SD are applicable tools in almost every stage of DMAIC, especially the Analyse, Improve and Control phases, because of their capability to test and identify potential bottlenecks and improvement areas. Findings show that the simulation tools such as CLDs, Group Model Building, Dynamic Balance Scorecards and Cost of poor quality all have the potential to add value to a Six Sigma methodology. Originality/value The findings of this study highlight the importance of further inquiry in this area of study. The finding of this study suggests that although the study on the integration of Six Sigma and simulations is increasing, empirical evidence on its effectiveness is still limited. Therefore, this study suggests more roadmaps and investigations aimed at merging Six Sigma methodology and various simulation technique. Moreover, studies that centre on hybrid or multi-method simulations within Six Sigma are also urgently necessitated.

Purpose – The purpose of this paper is to demonstrate the ability to researchers of using design of experiments (DoE) as a structured and systematic approach to performing systematic literature reviews. The authors demonstrate a simple case study illustrating the application of DoE in executing a systematic literature review on two popular topics in higher education: academic leadership and Lean Six Sigma. Design/methodology/approach – The methodology involves the systematic literature review of linking academic leadership with terms such as Lean, Six Sigma, Total Quality Management, Maturity Model and Continuous Improvement. The main tool used to structure the systematic literature review is a Taguchi Orthogonal Array design, specifically an L16 grid and the method is verified by conducting another review, replacing the term academic leadership with simply leadership. Findings – The approach identified at first no research papers linking the terms; however, when academic leadership was replaced with university, 19 research papers where discovered. The verification exercise, linking just leadership with the other search string generated over 1,000 results – demonstrating that the tool can find large volumes of articles if they exist, the search was completed for a ten year time frame – 2004 to 2014. Research limitations/implications – The case study focussed on a field which is known to have little current research and the verification exercise deliberately targeted a known large body of research. The authors will continue to use the approach and refine the technique over time. Practical implications – This approach would help any researcher despite of their discipline to identify opportunities and gaps in the current literature. Originality/value – The paper shows how DoE can be used in an academic research-based process. No other literature review approach currently exists which uses Taguchi approach to DoE to filter the search criteria.

Purpose The purpose of this paper is to present a systematic literature review to identify new avenues of research in line with the ongoing changes in quality and management required to firms, especially regarding customers. Design/methodology/approach This study uses a systematic review of the literature contained in the three databases Ebsco, JSTOR, and Springerlink and on the search engine Google Scholar. Findings An analysis of the literature identifies three different clusters of papers: “identification” papers, which show that customer focus has gained importance in recent times; “implementation” papers, which highlight that a general or shared model or scale to successfully implement total quality management (TQM) does not yet exist; and “impact-on-performance” papers, which show that few studies have considered the relationship between TQM and the issues of both marketing and performance, underlining the most significant gap in the TQM literature. Research limitations/implications This study is limited by the small number of databases and search engines used and by the restricted number of keywords used in searching these sources. Practical implications This work highlights a gap in the existing research and thus an incomplete consideration of the interplay between management, marketing, and quality issues, all centered on customers and other stakeholders. Researchers and firms are thus advised to adopt a wider view that considers the role of the quality process to support the firm’s engagement of customers in activities that enhance both the customer role and customer satisfaction. Originality/value This study uses a systematic literature review to review all critical factors of TQM and identifies new research avenues and different approaches to implementing TQM, focusing on the central role that customers play in achieving firm success.

Purpose The purpose of this study was to examine patterns in the research contributions from individuals in the field to detect whether they reflect the evolution of academic discussion concerning integration of Lean and Six Sigma methodology over a fixed time period. Design/methodology/approach Data was gathered from a keyword search of articles in the SCOBUS data base to determine the most frequent contributors in the areas of Lean, Six Sigma and Lean Six Sigma research. Searches were carried out over five-yearly intervals from 2000 to 2015 and the twenty-one top contributors in each time period were identified. Findings The findings show that research contributions have moved away from looking at the single methodologies of Lean and Six Sigma and towards research based on the integrated Lean Six Sigma approach. The analysis also suggested that researchers may be publishing papers using different methodologies in response to different challenges in selecting the most appropriate tools to meet the needs of the specific issues they are addressing rather than advocating a particular approach. Practical implications For organizations to optimize performance a flexible approach would be beneficial with consideration being given to the specific issue and the correct tools and methodology selected from an integrated system or from Lean or Six Sigma systems alone. Originality/value This paper has originality in its’ consideration of the patterns of research contributions over a fixed time period as a reflection of the shift in debate from exclusive Lean or Six Sigma approaches to a more integrated Lean Six Sigma system.

Purpose The purpose of this literature review was to explore to what extent quality management (QM) and nursing science offer complementary perspectives to provide better quality care, by looking at QM core concepts and tools. Design/methodology/approach A systematic literature review was conducted. Papers published in academic journals between January 2013 and December 2019 were included. A deductive content analysis was chosen using QM core values as an analytical framework. Findings The results showed that QM core values, methodologies and tools were found in the reviewed articles about intensive care unit (ICU) transitional care. The results indicated that core values in QM and the core competencies within nursing science in ICU transitional care are mutually dependent upon each other and exist as a whole. ICU transitional care is, however, a complex interpersonal process, characterized by differences in organizational cultures and core values and involving multidisciplinary teams that collaborate across hospital units. The QM core value that was least observed was committed leadership. Research limitations/implications Combining QM and nursing science can contribute to a deeper understanding of how to improve the ICU transitional care process by bringing complementary perspectives. Practical implications The included articles portray how QM is applied in ICU transitional care. Implications for future research focus on enhancing the understanding of how QM and nursing science can bring complementary perspectives in order to improve ICU transitional care and how QM values, methodologies and tools can be used in ICU transitional care. Committed leadership and team collaboration in ICU transitional care are areas that call for further research. Originality/value The findings contribute to the body of literature by providing important insights in terms of how QM core values, methodologies and tools are present in research about ICU transitional care and how the two research subjects, namely, QM and nursing science, bring complementary perspectives.

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.
