Purpose The purpose of this paper is to identify Lean Six Sigma enablers (LSSEs) and analyse the interaction among the enablers via a hierarchical model developed by employing interpretive structural modelling (ISM) and determine the driving and dependence power of enablers through fuzzy MICMAC (Matriced’ Impacts Croise´s Multiplication Applique´ea´un Classement) analysis. Design/methodology/approach An expert group of industry professionals and academicians is consulted at the initial stage as an input for ISM methodology to explore the paired relationship among LSSEs for each parameter of Lean Six Sigma (LSS) implementation. The outcome of ISM is further utilized by fuzzy MICMAC analysis to discover the enablers that are strong drivers and highly dependent. Fuzzy set is included in MICMAC analysis in order to obtain more precise output and effective model. Findings In total, 20 key enablers are identified through a literature review and expert opinion that emerged as the most significant factors towards LSS implementation. The identified enablers are portrayed into a structural form representing as input and output variables. Later, the driving and the dependence power of each enabler is presented in cluster form. Research limitations/implications The paired relationships among LSSEs are obtained through the interpretation made by the experts. The judgments of experts are subjective and may be biased; as difference in expert opinion may influence the final outcome. Conducting a large-scale survey may provide a better catch for interactions of LSSEs. Practical implications This study provides strong practical implications for researchers as well as industry practitioners. The industry professionals must deliberately focus on the identified LSSEs more conservatively during LSS implementation and the top management should plan strategically to avoid any implementation failure. Originality/value The present study identifies 20 crucial enablers of integrated LSS and presents them in a hierarchical form which will be beneficial for researchers and practitioners. The interactions among the enablers shown in cluster form will help in better execution of LSS.

Purpose – The purpose of this paper is to review and gather the latest critical success factors (CSF) of Lean Six Sigma (LSS) deployment and implementation into a comprehensive list of factors. Design/methodology/approach – The approach taken by authors in this study was to analyze the latest literature review starting 2010 onwards and focus on CSFs of LSS (not dedicated as Lean or Six Sigma) by excluding other improvement methodologies or initiatives, e.g. Lean, Six Sigma, TQM, TRIZ etc. Findings – Five significant CSFs were identified (initially 97 CSFs listed from 13 papers) out of nine groups/headers listed in clustering analysis using Affinity Diagram tool and new headers mapping. Practical implications – Most of the organisations were aware of the success story on LSS, but did not scrutinize or consider its CSFs. By knowing the outcome of this paper, it can help open eyes regarding readiness before implementing LSS. Originality/value – At the end of this paper, the authors tried to cluster the CSFs similarities that could intentionally provide the guidelines and references to industries/companies for successful deployment and implementation of LSS in future endeavours.

Purpose The purpose of this paper, builds on previous studies that explored the research patterns over 15 years, is to consider the current status of the integration of Lean and Six Sigma. More specifically, this research addresses whether Lean and Six Sigma are stronger together and explores the reasons why Lean researchers and practitioners may be less likely to integrate Six Sigma in their work. Design/methodology/approach The research utilises a survey of 25 established and respected academics and practitioners from 16 countries. The questionnaire is analysed using a direct content approach and coded in NVivo. Findings The findings suggest that challenges may lie in the perception and understanding of statistics as well as short-term rather than long-term focus on improvement. The findings also suggest that academics and practitioners believe that Lean Six Sigma has developed over time and will continue to develop and improve as a methodology rather than being replaced with a new methodology. Research limitations/implications The survey has a sample size of 25, albeit all respondents are established and very experienced practitioners and academics. Practical implications For organisations that are introducing or refreshing their continuous improvement initiatives, this research identifies some of the challenges and provides the opportunity to address them to maximise the opportunities for success and sustainability. Originality/value The value of this paper is that it further addresses the debate over the integration of Lean and Six Sigma for many organisations which still employ Lean alone, but beyond this it explores how they will continue to develop and whether they are a permanent edition to the quality management landscape or a transition to something else.

Purpose – The purpose of this paper is to elaborate, how the use of a joint-use strategy of Lean and Six Sigma can improve flexibility, robustness, and agility. Telecom manufacturing has been under tremendous change after dot.com bubble burst in the early 2000, and new competition has originated from Asia. Being successful requires now more than before, and joint-use of strategies is one option to survive. Design/methodology/approach – A single case study from a Swedish company operating in the telecom manufacturing was conducted. In particular, a Six Sigma project was followed and analyzed during 2002. However, the outcome of the Six Sigma project has been studied in longitudinal manner until 2014. Findings – The Lean Six Sigma strategy ensures flexible, robust, and efficient processes. However, to make them more agile in order to sustain in today's highly competitive environment, something more is required. This could include staff training, strengthening company culture and collaborating with key partners in the supply chain. Research limitations/implications – This study is limited to large company that usually has a lot of resources and choices where to put the strategic emphasis as well as has level of control of the supply chain operations. The situation could be very different in small and medium-sized companies and thus it may be more difficult to realize the Lean Six Sigma strategy in such environment. On the other hand, the processes in these companies are often less complex. Practical implications – This research provides guidance on how to manage the Lean Six Sigma strategy in order to ensure more flexible, robust, and efficient processes as well as how to perform a Six Sigma project in Lean environment, in a proper manner. Originality/value – This research provides guidance to companies regarding the applicability and properties of the Lean Six Sigma strategy. The paper will also serve as a basis for other companies and industries, on how to survive in difficult times.

Purpose The purpose of this paper is to review of the literature about lean six sigma (LSS) implementation in European organizations written by academics or practitioners from European institutions to extract useful conclusions about LSS adoption in European companies and to suggest direction for future research concerning the broader LSS application in them. Design/methodology/approach This study has been conducted by reviewing 58 papers, found in top journals, coming from European institutions that present studies of European companies and fulfill the selected inclusion criteria. Findings The analysis of the literature revealed the level of penetration of the LSS methodology in organizations of each European country. The study of the papers revealed the sectors and the size of companies that are more active in LSS application, the method used in each project, the tools which are deployed and the interconnection between LSS and other topics through the project implementation. Research limitations/implications The limited access provided by the authors’ institution only to three major publishers (Emerald, Elsevier, Taylor and Francis) and the focus of the search only in European organizations were the main limitations of this review. Practical implications This paper provides both academics and practitioners with valuable insights about LSS implementation in European organizations, presenting a complete analysis framework of the literature and highlighting gaps for further research. Originality/value An extended and detailed analysis of LSS adoption in Europe has not been conducted before. This review presents a clear view about how LSS projects in European organization have been applied so far and suggests ways of how the literature could be enriched to facilitate the LSS implementation.

Purpose – The purpose of this paper is to present an approach to successful supplier selection process (SSP) by understanding the dynamics between SSP enablers (SSPEs), using interpretive structure modelling (ISM) methodology and find out driving and the dependence power of enablers, using fuzzy MICMAC (Matriced’ Impacts Croisés Appliquée á un Classement) analysis. Design/methodology/approach – The group of experts from industries and the academics were consulted and ISM is used to develop the contextual relationship among various SSPEs for each dimension of supplier selection. The results of the ISM are used as an input to the fuzzy MICMAC analysis to identify the driving and the dependence power of SSPEs. Findings – The research presents a hierarchy-based model and mutual relationships among SSPEs. The research shows that there is a group of SSPEs having a high driving power and low dependence, which requires maximum attention and is of strategic importance, while another group consists of those SSPEs that have high dependence and low driving power, which requires the resultant actions. Research limitations/implications – The weightage obtained for the ISM model development and fuzzy MICMAC are obtained through the judgment of academician and few industry experts. It is the only subjective judgment and any biasing by the person who is judging the SSPEs might influence the final result. A questionnaire survey can be conducted to catch the insight on these SSPEs from more organizations. Practical implications – This category provides a useful tool for top management to differentiate between independent and dependent SSPEs and their mutual relationships which would help them to focus on those key SSPEs that are most significant for effective supplier selection. Originality/value – Arrangement of SSPEs in a hierarchy, the categorization into the driver and dependent categories, and fuzzy MICMAC are an exclusive effort in the area of supplier selection.

Purpose The literature of lean six sigma (LSS) is flooded with frameworks. But to date, there has been no attempt to expose the inconsistencies in the existing frameworks and associated research trends. The purpose of this paper is to critically review 26 LSS frameworks and highlight inconsistencies. The study also helps in analysing research trends and constructs of LSS frameworks, and facilitates new applications. Design/methodology/approach It uses Scopus database and finalises 26 frameworks in the LSS domain considering a timeframe from 2000 to 2017, using a structured literature review approach and involving domain experts. It uses a battery of systematic requirements-based questions to understand trends and covers building blocks/constructs also. Findings It reveals inconsistencies at three different stages, namely, the framework stage, usage stage capturing existing research trends and construct stage. It also offers details at building block/construct level. Thus, it offers guidance in reducing inconsistencies and possible modifications in the existing frameworks. It not only exposes existing constructs and sub-constructs but also guides about the new upcoming changes in the business influencing the LSS domain. It also educates about the strengths and weaknesses of each framework. Research limitations/implications This study tries to reduce inconsistencies, but does not offer new generalised or sector-specific framework. Practical implications This study will assist for modification/corrections in the existing frameworks by reducing inconsistencies and will encourage new frameworks to facilitate applications. Originality/value This is a unique study which offers frameworks-based review, portrays research trends and guides about constructs of a framework by exposing inconsistencies at each stage. It helps in reducing inconsistencies and offers guidance regarding modifications in the LSS framework considering upcoming challenges.

Purpose Compared to the manufacturing industry, Lean Six Sigma (LSS) lacks a clear methodology for its application in the tertiary service. One reason is the difficulties to assess information flow compared to physical flow. Indeed, the use of information flow as a process entry in the LSS method is not well investigated, mainly due to the difficulties in collecting adequate and sufficient data. The purpose of this research study is to investigate the application of LSS in the tertiary service, in particular, real estate development. Design/methodology/approach The paper is based on an action research methodology where LSS methodology is applied to solve client-dissatisfaction issue. One of its main causes is found to be the late delivery time. The work describes how the method was applied. Findings LSS is an adequate approach for making well-thought-out improvement in real estate development. Practical implications The work provides an implementation of LSS in real estate development. It also gives new insights into the LSS application in the tertiary service. The work also suggests practical recommendations and solutions to address the main challenges faced by real estate development. Originality/value Construction is governed by many processes that are difficult to identify and, even more, to assess. LSS helps identifying those which create real value for the client.

Purpose Lean Six Sigma (LSS) is a continuous improvement methodology used to increase the efficiency and effectiveness of processes. Although there are several articles published, only two have analyzed the literature from a bibliometrics perspective. The purpose of this paper is to analyze the LSS literature by bibliometrics, identifying its state of the art, scientific gaps and research trends. Design/methodology/approach Articles published up to 2016 in the database Scopus were investigated to identify the most significant articles, authors, journals, institutions and countries based on citation counting as well as the most frequent keywords and subject areas on LSS. Articles published in 2014, 2015 and 2016 were analyzed to point out scientific gaps and to identify eight main research trends on LSS. Findings The research trends are: “LSS implementation”, “Healthcare”, “LSS tools”, “Human factors”, “Expansion of results”, “SME”, “LSS combined with other methodologies” and “Education”. The research outcomes also point out the most significant articles, authors, journals, institutions and countries in LSS literature. Practical implications This research contributes to develop the state of the art of LSS and helps professionals as well as researchers to identify which issues new studies should address. Originality/value The performance of the literature is measured based on the number of citations and not on the number of published papers, and the bibliometric analysis covers the highest number of articles so far (319 articles). Besides, the identification of the main research trends on LSS is exclusively based on the most recent studies.

Purpose The purpose of this paper is to explore the most common themes within Lean Six Sigma (LSS) relating to small- and medium-sized enterprises (SMEs) within manufacturing organisations and to identify the research gaps in the existing literature. Design/methodology/approach Tranfield et al.’s (2003) systematic review methodology was utilised encompassing three stages: planning, conducting and reporting/dissemination. Findings The literature revealed that there are many areas in which LSS has been utilised with varying successes. In total, 52 journals have been reviewed and it has been concluded that although LSS is a powerful methodology, there are many gaps that exist in the literature and further research is needed to address these in the field of LSS. Research limitations/implications The papers included in the systematic review were peer-reviewed papers available in English. Due to these limitations, relevant papers may have been excluded. Moreover, the authors have excluded all conference and white papers for their inclusion in this study. Practical implications It is vital that LSS practitioners are fully aware of the benefits, limitations and impeding factors when implementing a LSS initiative. Therefore, this paper could provide valuable insights to ensuring maximum value, is obtained from LSS implementation in SMEs. Originality/value This systematic review identifies research gaps in the current literature and highlighting areas of future research which will be beneficial to many SMEs in their pursuit of value optimisation.

PurposeThe Indian manufacturing sector currently contributes 16–17% to gross domestic product (GDP) and gives employment to around 12% (2014) of the country's workforce. Among the various initiatives planned under Atma Nirbhar Bharat and “Make in India”, the Indian government aims to increase the share of the manufacturing sector to country's GDP to 25% by 2025. To ensure sustainable growth of the Indian manufacturing industries in global market, successful and implementation of strategies such as lean manufacturing, green manufacturing along with six sigma are crucial. This research aims at identification and analysis of barriers to successful implementation of integrated Lean Green Six Sigma (LG&SS) strategies.Design/methodology/approachBased on an evaluative literature review and expert's opinion, this research identifies 18 barriers to lean, green and six sigma implementation in the manufacturing industry in India. The inter-relationships among the barriers is identified using an integrated approach of ISM (interpretive structural modelling) and Fuzzy Matrice d’Impacts Croisés Multiplication Appliquée á un Classement (MICMAC).FindingsISM helps to derive key managerial insights and implementation plan based on the identified inter-relationships among the barriers. Fuzzy MICMAC analysis classifies the barriers into four categories, namely, autonomous, driver, dependent and linkage to understand their relative impact on the implementation of LG&SS practices in the Indian manufacturing industry. “Lack of cooperation and mutual trust between management and employees”, “The scarcity of time and work pressure”, “lack of continuous improvement work culture” and “lack of cooperation from suppliers” that forms the top most level of the model. “Weak legislation” is a highly significant barrier to LG&SS implementation in the Indian manufacturing industries.Practical implicationsIt is expected that the findings of this research will help the Indian manufacturing industry to derive a sustainable competitive advantage through an effective implementation of LG&SS practices.Originality/valueThis study can be seen as the first attempt in investigating barriers to successful implementation of lean, green and six sigma strategies in the Indian manufacturing industries using ISM and fuzzy MICMAC analysis.
