Abstract

Purpose

This paper compares impact of Industry 4.0 / emerging information and communication Technologies (ICTs), for example, Internet of things (IOT), machine learning, artificial intelligence (AI), robotics and cloud computing, on 22 organisational performance indicators under nine combinations of Lean Six Sigma (LSS) and quality management systems (QMS).

Design/methodology/approach

Survey of 105 Indian organisations was done about their experience of using QMS, Lean Six Sigma and emerging ICTs. Respondents included both manufacturing and service enterprises of different scales and sectors. The responses collected were compared, and statistically significant difference among them was evaluated using chi-square test.

Findings

The study confirmed statistically significant difference among 20 organisational performance indicators under different combinations of QMS, LSS and ICTs. These indicators include quality performance, delivery performance, sales turnover, inventory level and so forth. However, for two indicators, namely, absenteeism and throughput, significant difference in responses was not established.

Research limitations/implications

All possible combinations of QMS, LSS, only LSS tools and ICTs were not studied because of either theoretical impossibility (e.g. using LSS without LSS tools) or practically rare situations (e.g. organisations using ICTs and LSS without QMS). Furthermore, the impact from different sequences of implementing QMS, LSS and ICTs can be studied.

Practical implications

Using this study, practitioners can identify which LSS, Quality System and ICT combination results in best performance and quick success. On theoretical front, the study confirms impact of LSS and QMS on organisational performance.

Originality/value

This study evaluates organisational performance under several possible combinations of QMS, LSS, and emerging ICTs, which was so far unexplored.

Abstract

Purpose

With the growing pressure to gain optimum level of quality and speed, Lean Six Sigma (LSS) practices have drawn considerable attention as a viable alternative for process improvement. However, previous studies revealed that there is very little systematic and rigorous research to validate the claims. In this regard, this paper aims to empirically examine the effect of LSS practices on quality performance in the medical device manufacturing industry.

Design/methodology/approach

For this study, partial least square–based structural equation modeling (PLS-SEM) was used to empirically examine the effect of LSS practices on quality performance in Malaysian medical device manufacturing industry.

Findings

The findings of this paper revealed that LSS practices have a significant and positive effect on quality performance in the medical device manufacturing industry.

Practical implications

This paper will serve as a valuable implication for industry practitioners in providing them with a clearer managerial direction to exploit the strength of LSS practices to achieve company’s quality goals. Moreover, this study will serve as a basis for future LSS scholars, providing them with valuable insights and directions for future research.

Originality/value

This paper develops a conceptual LSS framework that captures the integrated nature of two methodologies and provides empirical evidence that supports the positive influence of LSS practices on quality performance; hence, it contributes to the growing body of LSS literature in both theoretical and empirical sense.

Abstract

Purpose

Many organizations have reported significant benefits after the implementation of Lean Six Sigma (LSS). Embracing LSS requires asking some important questions: How Lean Six Sigma Readiness (LESIRE) can be measured? How can an organization identify the barriers for LESIRE? Answers to these questions are critical to both academicians and practitioners. The paper aims to discuss this issue.

Design/methodology/approach

This study illustrates the development process of a Lean Six Sigma Readiness (LESIRE) evaluation model to assess an organization’s readiness for LSS deployment using the fuzzy approach. The model was developed from 4 enablers, 16 criteria and 46 attributes of LSS, identified through a literature review.

Findings

To demonstrate the efficiency of the model, this study testing the LESIRE evaluation model in three Indian SMEs. Using experts’ ratings and weight, the researchers calculated the Fuzzy Lean Six Sigma index (FLSS) which indicates the LESIRE level of an organization and the Fuzzy Performance Importance Index (FPII) that helps to identify the barriers for LESIRE.

Research limitations/implications

The main limitations of this study are that it did not consider the failure factors of LSS for model development and the LESIRE was only tested in manufacturing industries. Thus, future researchers could focus on developing a model with failure factors. The results obtained from the SMEs show that LESIRE is capable of assessing LESIRE in an industrial scenario and helps practitioners to measure LESIRE for the future decision making process.

Practical implications

The LESIRE model is easy to understand and use without much computation complexity. This simplicity makes the LESIRE evaluation model unique from other LSS models. Further, LESIRE was tested in three different SMEs, and it aided them to identify and improve their weak areas, thereby readying them for LSS deployment.

Originality/value

The main contribution of this study it proposes a LESIRE model that evaluates the organization for FLSS and FPII for LESIRE, which is essential for the organization embarking on an LSS journey. Further, it improves the readiness of the organization that is already practicing LSS.

Abstract

Purpose

The purpose of this paper is to review the existing literature on Lean Six Sigma (LSS) for services, construct a morphological analysis (MA) framework and identify research gaps to point to future research possibilities and priorities.

Design/methodology/approach

The MA framework is based on literature review of 175 papers published from 2003 to 2015, across 67 journals recognised by Scopus or ABS Academic Journal Quality Guide 2015. A three-phased methodology is used by the authors, with Phase1 featuring a five-stage systematic review protocol to identify relevant journal papers for review; Phase2 presenting a framework for classifying the reviewed papers in terms of their fundamental, methodological, chronological and sector-wise orientations; and Phase3 constructing an MA framework on the classified papers and identifying the research gaps.

Findings

The MA framework constructed based on six dimensions, namely, organizational context of applications, desired outcomes, implementation systems, LSS tools and techniques, integration with other management philosophies and evaluation methods, involving 40 focused themes, has revealed 355 distinct research gaps as opportunities for future research.

Practical implications

This paper confirms the existence of substantial scope and points to specific topics for further research in the area of LSS for services. The findings demonstrate the gaps in academic research on the subject. In addition, the study also helps organisational leaders and practitioners to look at LSS from a holistic perspective in the services context.

Originality/value

The MA framework of the existing literature on LSS for services presents a unique, systematic effort to identify research opportunities. In addition, a five-stage systematic review protocol is proposed in this paper. This could be valuable to researchers and practitioners in enabling them to systematically review the literature on research subjects of interest to them.

Abstract

Purpose

The purpose of this paper is to extend previous studies to a hybrid analysis of three business improvement practices of Lean, Six Sigma and Lean Six Sigma (LSS) within last two decades and identify the research gaps and focusses in more comprehensive and robust classification framework.

Design/methodology/approach

A secondary data collection and a literature review were conducted to collect information about peer-reviewed journal articles under six dimensions of a tested classification framework. The frequency and distribution analysis was conducted followed by Pearson’s χ2 test to analyse any relationship between dimensions of framework in order to identify the gap.

Findings

Despite a relatively great deal of regular research outputs about Six Sigma, Lean and LSS, academic journal articles have been found mainly limited to a few industries, themes and countries. “General manufacturing”, “healthcare”, “automotive” and “electronic industries” as sectors; and “tools and techniques”, “benefits” and “success factors” as key themes have been mostly approached by LSS, Six Sigma and lean management articles. It was also found that there is still a great disparity amongst researchers and journals to publish about these three business improvement practices.

Research limitations/implications

The research publications for LSS, Six Sigma and lean management should have wider approach towards various manufacturing and service sectors, countries and journal publications. A greater level of research/enterprise activities has been found in relation to LSS and Six Sigma articles compared to lean management articles.

Originality/value

This research aims to identify the gaps in research publications during last two decades about three major business improvement practices in one package and through more comprehensive robust classification framework and also through comparative analysis.

Abstract

Purpose

Although the literature on Lean Six Sigma (LSS) implementation has evolved, a deeper understanding of the LSS practices applied in organisations in developing countries is needed. This paper aims to analyse LSS in a manufacturing company in the context of LSS implementation in an emerging economy.

Design/methodology/approach

This paper uses case-based research. Data collected in a large manufacturing company through multiple sources of evidence were triangulated to derive the findings. This paper analyses aspects related to the implementation of both programmes and their synergy, as well as some critical and failure factors.

Findings

The main results show that Lean and Six Sigma are applied separately in two different programmes. Some aspects that are necessary to increase the integration of both approaches were identified while considering each phase of the DMAIC and the current approach applied by the company. Although some positive results have been achieved, there are many critical and failure factors that may influence the implementation of both approaches, such as employee training and changes in the organisational environment. Finally, the comprehensive integration of both approaches needs to be undertaken by the company.

Research limitations/implications

The findings from this single case study cannot be generalised.

Practical implications

This paper may be used as a guiding reference for managers and consultants to help them when working towards more successful LSS implementation.

Originality/value

First, this paper investigates LSS in a manufacturing firm located in a developing country; this issue is still seldom addressed in the literature. Second, it may contribute to practitioners’ knowledge by delivering insights into a real context, as well as the relevant issues to be addressed when implementing LSS in similar contexts.

Abstract

Purpose

The purpose of present study is to expose the detailed review for benefits and challenges about implementation of Lean Six Sigma (LSS) in business organization and spread of LSS literature in term of various sectors wise, research methodology wise and journal wise.

Design/methodology/approach

This paper covers the literature on LSS from 2000 to 2018. The authors have selected a large number of research papers using the keywords as Lean Six Sigma implementation in automotive, micro small medium enterprises, health care, education, financial sectors and many more. A total of 216 research papers have been reviewed on LSS distribution of sector wise, research methodology adopted, active countries, year of publication and critical barriers in implementation of LSS.

Findings

The present literature classifies the spread of LSS in four important sectors of manufacturing, health care, human resource, financial and education. It presents the critical barriers and benefits of LSS implementation in various sectors mentioned above and an important research gap, where practitioner/researcher can focus more during their research on LSS.

Practical implications

It is important for industry, researchers and LSS practitioners to be aware about challenges and success factor during LSS implementation in various sectors such as manufacturing, education, financial, human resource and health care. Hence, this paper could provide significant and valuable insights to industry and practitioners for successful implementation of LSS projects.

Social implications

LSS results in reduced waste, defects and improve process, which in turn provide high-quality products at minimum cost, and this leads to customer delight, which ultimately raises the societal living standard. The results encourage LSS practices without fear because there is a huge discussion of near about all success and failure parameters about LSS.

Originality/value

To the authors’ best knowledge, no studies have still covered the literature review of LSS implementation in three different sectors: manufacturing, service and process. The present study was mainly focused on presenting a systematic review of literature in said sectors and found the gap between current status and future direction for the implementation of LSS in different areas.

Abstract

Purpose

The literature in the field of Lean Six Sigma (LSS) is escalating with frameworks, but, till date, no effort has been made in existing literature to critically reviewing LSS frameworks. The aim of this paper is to investigate the literature about Lean, Six Sigma and LSS frameworks and critically reviewing the existing literature over numerous parameters.

Design/methodology/approach

This study focuses on a literature review of Lean, Six Sigma and LSS frameworks. The time span of this analysis is 30 years. The analysis is restricted to searching online databases such as Elsevier Science direct, Taylor and Francis, Emerald, Springer link, Wiley Inter-Science and Inder-Science. A total number of 58 frameworks have been used as sample size for this study. The study focuses on reviewing these 58 frameworks based on measures such as the novelty of frameworks, source of frameworks, framework verification, approach of verification and identification of vital elements/tools/constructs of frameworks and lastly comparative analysis of all these 58 frameworks

Findings

The analysis has identified major discrepancy such as laxity of researcher toward utilizing existing frameworks, lack of participation of practitioners and consultants in the development of LSS frameworks, and the elements/constructs used in structuring the frameworks are highly incoherent. Higher proportions of frameworks are verified through various modes of verification such as survey, case study, simulation, which encourages other researchers for applicability of the frameworks. Case study is found most popular research design method for verification of frameworks. Various frameworks are highly abstract or superficial. Some of the frameworks do not show how each construct/element are related to implementation in the organization. Out of 58 frameworks, the only single framework is highly comprehensive. A coherent framework for LSS is still lacking.

Research limitations/implications

This analysis is limited to peer review articles from Elsevier Science direct, Taylor and Francis, Emerald, Springer link, Wiley Inter-Science and Inder-Science databases and contains the search keywords in title only.

Originality/value

This study is first of its kind attempt, making an effort to the knowledge of the authors to critically review Lean, Six Sigma and LSS frameworks. This analysis will assist to recognize the LSS filed trends and framework applicability.

Abstract

Purpose

The purpose of this paper is to share the experiences and perspectives of three practitioners from two continents on the subject of Lean Six Sigma (LSS) from both academic and industrial viewpoints. The authors of the paper have each been working on the topic of LSS over the past 15 years and have contributed over 150 journal and conference papers to the topics of lean and Six Sigma.

Design/methodology/approach

The approach is to synthesize the practical experiences and research conducted by three authorities on the topic of LSS. In addition, relevant secondary data have also been used in the sections where and when appropriate.

Findings

The authors initially present the history of LSS emphasizing the importance of integration of the two most effective process excellence methodologies over the past 30 years. The authors also report the current trends of LSS in organizations as well as the emerging future trends. They argue that LSS will continue to grow and evolve across the globe for several years.

Practical implications

The paper is intended to be equally useful to both academics and practitioners who are interested on the topic of LSS. From a pure practical standpoint, the paper provides an overview of the past, present and future trends of LSS as a powerful business strategy and problem-solving methodology for all industrial sectors, irrespective of their size and nature. The documentation of the history and recent developments in LSS should be useful to researchers in academia.

Originality/value

In authors’ best knowledge, there are no recent journal articles which cover all the three of these aspects; the past, the present and the future of LSS. This paper presents the above three aspects in a unique manner and addresses the gap between the current state and future directions of LSS.
