Purpose This research has the following specific objectives: provide an overview of the literature addressing operational excellence (OE) and OE in emerging countries; propose an integrative framework of OE attributes; and propose future research directions for the OE literature. Design/methodology/approach To remain competitive in industry, many organizations are implementing OE initiatives. However, achieving OE in emerging markets has been a pressing challenge due to the scarce knowledge on how it works. Through a systematic review of the literature, this study aims to contribute to a deeper understanding of the concept of OE in emerging countries through the triple bottom line. Findings This study has found nine attributes of OE based on the three pillars of sustainability or triple bottom line (economic, environmental and social). Four of them were the most cited and served to build the proposed framework. The analysis concludes that most of the studies related to OE in emerging countries have been carried out in Asia. Finally, based on the results obtained from the literature review, six points of future research are proposed based on three research directions: OE in emerging countries, active participation by employees and culture generation and finally, research methods. Originality/value The gap that is filled in this study is that some authors have studied the application of OE in emerging countries, specifically on the Asian continent. In those cases, the literature is either oriented to describing OE from different perspectives or to its application in different companies, some of which are emerging countries. However, to the best of the authors’ knowledge, there is no study that describes the specific and complete aspects that make up a model of OE and which can show how this model can be applied in emerging countries.

Purpose This study aims to improve the buying experience for both customers and providers by presenting a conceptual basis which seeks to expand the usual understanding, representation, mapping and measurements of the different value and non-value stages of a customer purchase journey (CPJ). Design/methodology/approach Inspired by the precepts of lean thinking, with emphasis on the value stream mapping method, the approach is based on an in-depth analysis of a real and typical e-commerce acquisition of an electronic customised product (a mobile phone) during the COVID-19 pandemic. Findings This study demonstrates different types of consumer stages, values and wastes for the CPJ. This allowed the development of a mathematical formulation – named customer journey engineering (CJE) – from which improvements of the different categories can be identified. Exemplifying with those whose implementations require no further efforts or costs, the following results could be readily obtained in the case studied: a reduction of 96 h of non-value activities, an improvement of approximately 15% of the established index for customer satisfaction and avoidance of loss worth US$50 for the analysed customer. Research limitations/implications The consistency and applicability of the qualitative and quantitative findings presented here should be examined further in other customer purchase scenarios, allowing enhancements of the CJE approach. Originality/value Regardless of the context in question, this investigation attempts to identify and precisely define any common universal elements, often overlooked, which constitute the structure of any CPJ and are crucial for its understanding and improvement.

Purpose This study aims to examine the influence of lean management practices on organizational process effectiveness and maturity. The underlying assumption of this paper is that lean management practices may have a positive relation with the initiation and the adoption of a process management approach and be a first step to process management success. Design/methodology/approach Through a quantitative perspective, a survey was carried out in the Brazilian Federal Police with a valid sample of 991 participants. Data analysis was executed with confirmatory factor analysis and structural equations modeling. Findings Lean management practices have a positive influence on the Brazilian Federal Police process maturity and on process effectiveness. Process maturity has a positive impact on process effectiveness. The results extend the applicability of lean management practices in the public service scenario. The results will decrease the high failure rates in process transformation projects. Research limitations/implications The main limitation of this study is that the researchers could not maintain full control of the research respondents because the data collection was carried out online. Practical implications Considering a scenario of increased pressure to upgrade organizational decisional process in the public sector and to offer better public services, the lean management practices can effectively contribute to the development of strategies and actions that will enhance a more effective public service management reality. Social implications This study may contribute as a source of empirical data for future research in other national public organizations and may assist others to redesigning its strategies and actions to achieve excellence in decision-making, by adopting a more agile quality public service with less costs and waste. Originality/value New measurement and structural models were defined to analyze lean management practices in the public service as the predictors of organizational process maturity and effectiveness. The discussion on lean management practices, as a first step in process approach applicability, enhances a new process-based management perspective.

Purpose This study aims to address Industry 4.0 (I4.0) technologies that can improve the research and implementation of lean supply chain management (LSCM) and the enhanced LSCM subfields in I4.0 technologies. Design/methodology/approach The authors conducted a systematic literature review to detect, categorize and assess recent data, highlighting patterns and providing suggestions for potential research in this field, to investigate I4.0 literature and its effect on LSCM. The authors examined 79 published types of research from the Scopus database that were published between 2010 and 2021 and classified them into four LSCM fields: logistics, production, supply chain and marketing. Findings The authors can emphasize the fact that the literature on this topic is in progress, from early German academic research to the current creation of new effects around the world. The majority of the potential effects investigated were discovered to improve specific areas that ultimately enhance the practices of the four LSCM domains as well as performance outcomes. The authors were also able to assess the extent to which present and upcoming I4.0 technologies can improve LSCM research and implementation. Originality/value To the best of the authors’ knowledge, this is the first study of its kind. Although some research looked into various areas of I4.0 and LSCM topics, there has been no research specifically looking into the impact of I4.0 on LSCM. The originality of this study lies in the treatment of the main fields and sub-fields of LSCM, which can benefit from the technologies of I4.0. Academic scholars interested in the research topics may benefit from the findings of this study. Organizations in various industrial sectors, particularly manufacturing, where lean thinking is used, business professionals specialized in lean operations and supply chain management, along with anyone else who wants to learn more about the interrelationships between I4.0 and LSCM.

Purpose Existing research evidence shows a fragmented understanding of the roles of first-line employees (FLEs) as essential factors for successful lean implementation in small- and medium-sized enterprises (SMEs), provoking recent calls for additional research on the identification of enablers and barriers for lean acceptance among workers. Therefore, this paper aims to identify related enablers and barriers to lean implementation among FLEs and determine future research avenues for improving the understanding of lean methodology implementation in SMEs. Design/methodology/approach Relying on a systematic literature review methodology, the authors aimed to synthesize and evaluate available peer-reviewed papers on the role of FLEs in lean implementation in SMEs. General descriptive and thematic analysis comprehensively depicted the selected research topic and identified the main themes within collected papers and potential future research questions. Findings The authors identified four main themes related to FLEs’ role in lean implementation: cultural change factors, employee characteristics, management involvement and lean job design. Within each theme, the authors present a comprehensive overview of FLE-related factors and associated enablers and barriers that should be considered for a successful lean implementation in SMEs. Practical implications The research outcomes are important to practicing managers in SMEs, helping them facilitate lean acceptance and enhance the likelihood of successful lean implementation. Originality/value The insights from this study present building blocks in developing a lean implementation model for SMEs that considers the FLEs’ role more comprehensively.

Purpose Health care organisations implement lean six sigma (LSS) methodology to achieve improved performance in terms of cost, quality and productivity. However, the way it gets implemented differs between organisations. Hence, this paper deal with a review of case studies describing the implementation of LSS in health care organisations to understand the nuances of implementation and identify future research directions. Design/methodology/approach The journal articles indexed in the Web of Science and Scopus database were filtered out. In total, 154 articles were evaluated using specific structural dimensions to categorise the literature into various groups, and content analysis was performed to synthesise the same. Findings This review revealed that the number of articles publishing the application of LSS in health care has been increasing in the last five years. Academic hospitals play a pivotal role to bridge the gap between LSS theory and practice. Despite this fact, certain themes remain unexplored. Not many studies are available that document the application of LSS in non-clinical areas such as pharmacy, internal logistics, maintenance and medical records. Only 20% of articles mentioned the post-intervention data up to three years, thus questioning the sustainability aspect of the achieved improvements. Research limitations/implications Various research gaps were identified, which can be used by the researchers to build the body of knowledge in the domain of LSS in health care. Practical implications This review provides a diversified view regarding the utility of LSS in the health care scenario. The findings will provide valuable insights for the health care practitioners regarding tools, techniques, drivers and performance measures. Originality/value To the best of the authors’ knowledge, this is the first study to review only the case studies that describe the implementation of LSS in the health care sector.

Purpose The analyze phase of Lean Six Sigma (LSS) project is an important phase where the project heads and organizational directors need to select the critical issues for further improvements. The present work is primarily focused on analyze phase of LSS project to prioritize the critical to quality (CTQ) in a particular case industry. Design/methodology/approach The CTQ prioritization is being done based on the five evaluation criteria found from the literature. The weights of the criteria are determined through the modified digital logic (MDL) method. The identified CTQs in assembly section of case industry have been ranked through the gray relational analysis (GRA) under fuzzy environment.

目的精益六西格玛（LSS）项目的分析阶段是项目负责人和组织主管需要选择关键问题进行进一步改进的重要阶段。目前的工作主要集中在LSS项目的分析阶段，以确定特定行业中关键质量（CTQ）的优先级。设计/方法论/方法基于文献中的五个评估标准对CTQ进行优先排序。通过改进的数字逻辑（MDL）方法来确定准则的权重。在模糊环境下，通过灰色关联分析（GRA）对案例行业装配环节中识别出的CTQ进行了排序。该研究的结果已使用模糊VlseKriterijumska Optimisacija I Kombrisno Resenje（VIKOR）进行了验证。结果发现，在MDL权重为0.3的其他标准中，“成本”标准最为显著。通过模糊GRA，在已识别的十个CTQ中，机架系统的不可用性是机箱行业装配部门最关键的问题。案例行业的行业经理和生产负责人强烈支持所获得的结果，并实施了建议的解决方案。独创性/价值为了在竞争环境中维持并在正确的时间生产出高质量的产品，组织需要根据其关键性控制其CTQ。为此，由于各种标准和子标准的迷人性质，选择最关键因素的决策变得相当复杂。本研究是在LSS项目分析阶段实现多准则决策方法的首次尝试。

Purpose The manufacturing sector has been observing various benefits by the implementation of lean manufacturing practices. However, the manufacturing sector has neglected the significance of health and safety management system implementation. The purpose of this research is to propose and validate an occupational health and safety management systems (OHSMS) framework based on critical success factors and their relationships in the lean manufacturing organizations. Design/methodology/approach A critical literature review was conducted to identify the success factors of OHSMS. Subsequently, a questionnaire survey and semi-structured interviews were conducted with experts from process industries to consolidate the critical success factors. After consolidating the critical success factors, relationships among critical success factors were established with the help of interpretive structural modelling using a team of 12 experts from industry and academia. These established relationships helped in proposing the hierarchical implementation framework. Finally, the validation of the proposed implementation framework was carried out using structural equation modelling (SEM). Findings This study has identified nine broader critical success factors for implementation of OHSMS in lean manufacturing organizations, especially the process industry. Subsequently, this study has proposed an OHSMS framework with nine broader critical success factors to implement in lean manufacturing organizations. Finally, the proposed framework has been validated using SEM with an appropriate sample size. Practical implications This study is helpful to the organizations to implement OHSMS without losing the essence of lean manufacturing strategy. This study has proposed a framework for implementation of OHSMS in the lean manufacturing organizations, especially process industry sector. This study also provided confidence to the organization through the validation of proposed framework in the process industry. Originality/value To the best of the authors’ knowledge, this study is first of its kind in this field of OHSMS in lean manufacturing organizations, especially the process industry. This study has involved both academicians and industry experts to bring more robust outcomes. This study proposed a unique framework to implement OHSMS in lean manufacturing organizations. This study has considered a comprehensive literature to develop a framework for OHSMS in lean manufacturing organizations. An implementation framework was proposed by considering both the academicians’ and industry professionals’ opinions. The proposed framework was statistically validated. This will be helpful in effective implementation of OHSMS strategy in lean manufacturing organizations, especially process industry sector.

Purpose This paper aims to deal with the selection of the sustainability-oriented Green Lean Six Sigma (GLS) project for the manufacturing industry in the complex decision-making environment. Moreover, the study also proposes a GLS implementation framework for improved organizational performance. Design/methodology/approach GLS project selection has been done based on the six sustainability-oriented criteria formed from 17 sub-criteria (found from the literature and developed by authors). The weights of the criteria have been determined through the entropy method. The projects have been ranked based on the criteria through the advanced decision-making approach: grey relation analysis (GRA). The results of the study were validated using best worst method and sensitivity analysis. Findings It has been found that the productivity-related criterion is the most significant among other criteria with entropy weight of 0.2721. GRA has been used in this research work to rank the potential GLS projects in a manufacturing industry based on six sustainability criteria, to select a project that exhibits the maximum potential for sustainable improvement. The machine shop has been found as the most significant GLS project with grey relation grade of 0.4742. Practical implications The present study facilitates practitioners and industrial managers to implement an inclusive GLS approach for improved sustainability dynamics through effective GLS project selection and implementation framework. Originality/value With increased globalized competition in recent times, new projects are being considered as the foundation stone for organizational success. The decision-making becomes quite complex to select an effective project due to the intriguing nature of various criteria, sub-criteria and different aspects of sustainability. To the best of the authors’ knowledge, the present study is the first of its kind that provides ways for the selection of sustainability-oriented GLS projects.
