  • The academic pattern of the Lean Six Sigma approach: a descriptive content
           analysis of project-based studies within Turkey

    • Free pre-print version: Loading...

      Authors: Fulya Almaz , Nuray Akar
      Abstract: The purpose of this study is to present the academic pattern of project-based studies on the Lean Six Sigma (LSS) approach in a comparative manner in the context of Turkey. Focusing on the context of Turkey, a detailed search was conducted at the National Thesis Center of Turkey, and on Google Scholar between November 28 and December 15, 2021, using the keywords “Lean Six Sigma” and “Lean 6 Sigma” in both Turkish and English. As a result of this search, no conference proceedings on the subject were found. However, 25 postgraduate theses and 19 articles were accessed. It was determined that ten of the 19 articles were produced from these theses. It was observed that nine of the 25 postgraduate theses contained conceptual analyses. At this point, it was concluded that the project-based theses conducted in the context of Turkey provided the necessary representation on the subject. Therefore, the 16 postgraduate theses that had been accessed constituted the sample of the study. These 16 theses were subjected to a comprehensive evaluation with the systematic analysis design, with descriptive content analysis being used as the data analysis tool of the research. In this context, the theses were examined using parameters such as type, number, year, university, institute, department, discipline, original language and title of advisor. Other parameters used were purpose, industry, duration, team, results, tools and techniques of the LSS projects mentioned in the theses. It was determined that the number of postgraduate theses on LSS was low in number, with only one study having been performed at the doctoral level, and most studies having been produced in 2019. In addition, it was observed that the subject had been studied by different universities, institutes, disciplines and departments with the LSS spreading to different academic disciplines. Most of the relevant theses were written in Turkish, and it has been determined that these theses were mostly carried out under the supervision of academicians with the title of assistant professor. It was also found that the purposes of the theses, the tools used throughout the process and the results obtained were per the LSS spirit. On the other hand, it was determined that the duration of the project and the composition of the team members would vary due to the diversity of features that make the internal dynamics of the projects clear. The research revealed the academic pattern of the project-based studies on the LSS in the Turkish context. The use of systematic review design and descriptive content analysis as data analysis tools in the research is an important initiative. While the uniqueness of the studies carried out on such a practical subject cannot be discussed, the holistic approach of these studies increases the contribution value of the research. At this point, this study is considered to be especially valuable for an understanding of LSS research in country-specific conditions. In this aspect, it is an aim of the aforementioned research to become a resource for researchers and practitioners interested in LSS, with this research providing a basis for making contextual comparisons in the future.

  • Implementing lean six sigma methodology to reduce the logistics cost: a
           case study in Turkey

    • Free pre-print version: Loading...

      Authors: Gülşah Şişman
      Abstract: The purpose of this study is to propose the implementation of Lean Six Sigma (LSS) framework in supply chain by providing an actual case study of how to reduce the logistics cost. In this paper, it is shown how LSS approach, basic tools and Define, Measure, Analyze, Improve and Control methodology can significantly improve a company by enhancing the supply chain and reducing the logistics expenditures. Root causes to the main problem of this study were analyzed to identify appropriate solutions. After the implementation of solutions, the company’s product quality and internal communication were improved. Correspondingly, the percentage of customer orders that have to be transported by road instead of maritime reduced to 5% from 13% and the percentage of the road transportation cost paid unnecessarily by the company decreased to 1% from 5%. This case study provides a roadmap and step-by-step implementation of LSS framework for especially companies in plastics industry. To the best of the author’s knowledge, this paper is the first example of a LSS case study conducted in Turkey to improve the supply chain of a company by targeting primarily a reduction on logistics costs.

  • Critical success factors of Lean in Higher Education: an international
           perspective

    • Free pre-print version: Loading...

      Authors: Alinda Kokkinou , Ton van Kollenburg
      Abstract: Continuous improvement initiatives such as Lean in Higher Education (HE) institutes are an emerging topic for research. Under pressure to do more with less, institutes of HE are increasingly adopting the tools and methods of lean to improve their quality practices. Nevertheless, institutes of HE differ significantly from business organizations. The purpose of this study was to examine the critical success factors (CSFs) of continuous improvement in this homogeneous industry. Two other contextual factors, implementation approach and national culture, are examined. A mixed methods approach, combining Q-methodology, online surveys and interviews, was used to investigate the CSFs of lean implementation in HE. Participants were recruited from an international network of lean practitioners in HE. Using Q-methodology, three perspectives of CSFs in HE were identified. Lean implementation at institutes of HE is characterized by a bottom-up approach, involving mostly supporting processes. Contrary to business organizations, the role of management in the implementation of Lean in HE is limited and attention should instead be directed to employee empowerment and customer focus. The findings also showed that, at least for institutes of HE, organizational culture is more influential than national culture. When management involvement is limited, a bottom-up implementation of lean is recommended, centered on improving university-wide supporting processes, promoting cross-departmental cooperation and overcoming the silo mentality. This approach requires an emphasis on a specific set of CSFs, namely, employee empowerment, sharing success stories and training. The study findings enrich conceptually based lean implementation frameworks for HE that advocate a top-down implementation approach.

  • Virtual reality supported trainings for lean education: conceptualization,
           design and evaluation of competency-oriented teaching-learning
           environments

    • Free pre-print version: Loading...

      Authors: Thomas Riemann , Joachim Metternich
      Abstract: The purpose of this approach is to structure and facilitate the development of competency-oriented virtual training scenarios. This approach should help to develop reproducible results. This publication presents a procedure for the structured, competency-oriented design of virtual teaching–learning environments. The procedure is based on the competency-oriented design of learning factories according to Tisch and consists of a total of three phases with various substeps. The different steps of the method are presented by means of an application example and the generated scenario is evaluated by means of a competency measurement according to Glass regarding its suitability for teaching competencies. In addition to an application example that introduces the approach, this publication presents concrete results from the research project. In addition to a review of the opportunities and limitations of virtual reality (VR) in continuing education, these also refer to possible, realizable requirements for the use of VR. In addition, results on the suitability of VR learning environments for competency development in the context of value streaming mapping training are presented. This approach represents a substantial extension of existing concepts for the design of physical learning factory training for lean topics. It can help learning factory operators and other training providers to design competency- and user-oriented virtual training. VR offers a multitude of potentials in this context, but these can only be exploited through conscientious use of the technology.

  • Impact of commercial, financial and corporate affairs on operational
           excellence of the Indian mining industry

    • Free pre-print version: Loading...

      Authors: Padma Charan Mishra , Rashmi Ranjan Panigrahi , Alaka Samantaray
      Abstract: This study aims to identify the impact of commercial issues (CIs), financial issues (FIs) and corporate affairs (CAs) on operational excellence (OE) of the mining industry. A purposive sample of size 321 was collected from Indian mining executives with more than ten years of exposure to the mining field. Factors are identified and confirmed with the use of confirmatory factor analysis. The structural equation modeling technique was then applied to understand the unique as well as the complex relationships between FI, CI, CA and OE. The results indicate that all three issues, CI, FI and CA, have an influence on OE in the Indian mining industry. Among the variables of the issues considered in this study, marketing products and size and quality of products (from CI); scale of economies (from FI); risk management (from CA); and transportation and machine operation (from OE) are the highest influencing variables. This study has its limitations in sampling, the timing of sample collection and their mode. The samples were collected from only massively deposited large mines. Business managers of the mining industry will be more vigilant and aware of those indirect variables such as marketing products, size and quality of products, scale of economies and risk management, which can influence OE apart from major influencing variables such as transportation and machine operations and production scheduling. To the best of the authors’ knowledge, this is the first study in the mining industry to evaluate the impact of these three issues on OE. The originality of this research lies in testing the CI, FI and CA of the mining industry with OE, which is completely new to this field.

  • Development of a framework for utilising Lean Six Sigma’s intangible
           impacts in creating organisational innovation climate

      Abstract: The purpose of this paper is to develop a framework that illustrates the role of Lean Six Sigma (LSS) in creating organisational innovation climate by investigating the relationship between LSS’s intangible impacts and organisational innovation climate factors. A self-administrated survey questionnaire was distributed among 145 public sector officials to get their opinions on the relationship between various observable elements of LSS’s intangible impacts and organisational innovation climate factors, where a response rate of 73.8% was achieved. The collected data were demographically, descriptively and statistically analysed. Accordingly, a house-of-pillars-based framework that illustrates the role of LSS’s intangible impacts in creating innovation climate in an organisation was developed. Results from this study indicated that LSS’s intangible impacts on organisational structure and hierarchy, culture, change adaptability, utilisation of staff and staff’s behavioural aspects are positively related to many of organisational innovation climate factors such as trust and openness, challenge and involvement, support for ideas and freedom and autonomy. The findings of this study are based on the data collected from public sector organisations in the UAE and are supported by relevant literature. However, this study can provide useful guidance for further research for the generalisation of the results to wider scopes in terms of sectors and geographical domains. The findings of this study will provide UAE public sector officials with a clear roadmap on how to use LSS for promoting innovation and fostering its implementation in practice. This study will also encourage professionals in public sectors to integrate LSS into their innovation strategies to enhance organisational innovativeness and improve service quality. It is one of the first studies that explores LSS’s intangible impacts and assesses their relationship with organisational innovation climate factors. Hence, this study offers valuable insights for both academics and practitioners and is expected to lay a foundation for a better understanding of how LSS’s intangible impacts can be used in creating organisational innovation climate.

  • Fostering insights and improvements from IIoT systems at the shop floor: a
           case of industry 4.0 and lean complementarity enabled by action learning

    • Free pre-print version: Loading...

      Authors: Henrik Saabye , Daryl John Powell
      Abstract: This paper aims to investigate how manufacturers can foster insights and improvements from real-time data among shop-floor workers by developing organisational “learning-to-learn” capabilities based on both the lean- and action learning principle of learning through problem-solving. Second, the purpose is to extrapolate findings on how action learning can enable the complementarity between lean and industry 4.0. An insider action research approach is adopted to investigate how manufacturers can enable their shop-floor workers to foster insights and improvements from real-time data at VELUX. The findings report that enabling shop-floor workers to use real-time data consist of developing three consecutive organisational building blocks of learning-to-learn, learning-to-learn using real-time data and learning-to-learn generating real-time data − and helping others to learn (to learn). First, the study contributes to theory and practice by demonstrating that a learning-to-learn capability is a core construct for manufacturers seeking to enable shop-floor workers to use real-time data-capturing systems to drive improvement. Second, the study outlines how lean and industry 4.0 complementarity can be enabled by action learning. Moreover, the study allows us to deduce six necessary conditions for enabling shop-floor workers to foster insights and improvements from real-time data.

      Abstract: An understanding of the motivation of individual employees to adopt lean practices is fundamental to successful lean implementation. This study aims to investigate the adoption of lean practices and provides an analysis of the individual-level factors necessary for lean implementation. This study presents a method for assessing the impact of individual-level factors in a company deploying lean within a biopharmaceutical manufacturing subsidiary. The case study explores the attitudes of individuals within a functionally structured organisation undergoing a lean implementation initiative. A quantitative data collection approach was used to capture data from employees in a medical device manufacturing organisation. The study found that personality and affective organisational commitment positively affects an individual’s intention to adopt lean practices. Employees with greater levels of affective commitment are more likely to partake in lean-related practices. Individuals in functions that directly support the production process, as opposed to those in functions that indirectly support production, are more likely to participate in lean practices. Finally, individuals in supervisory roles are more likely to adopt lean practices than those in non-supervisory roles, and management should involve top performers in lean. There is a paucity of case study research in the area of individual-level factors for lean practice adoption. The findings of this study offer practical guidance on individual-level factors for lean practice adoption and illuminate new avenues for future research. This analysis also makes a practical contribution to the literature. From a managerial perspective, understanding why certain employees are more willing to adopt lean practices contributes to an overall lean organisational readiness and implementation framework. This insight enables the development of carefully tailored communication and training programs for managing employee motivation for and receptivity to lean.

  • Value stream mapping from the customer's perspective: expanding concepts,

      Abstract: 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). 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. 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. 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. 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.

      Authors: Rafael Henriquez , Andrés Muñoz-Villamizar , Javier Santos
      Abstract: 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. 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. 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. 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.

      Abstract: 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. 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. 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. 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. 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. 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. 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.

      Abstract: 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. 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. 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. 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.

      Authors: Viktorija Knapić , Borut Rusjan , Katerina Božič
      Abstract: 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. 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. 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. The research outcomes are important to practicing managers in SMEs, helping them facilitate lean acceptance and enhance the likelihood of successful lean implementation. The insights from this study present building blocks in developing a lean implementation model for SMEs that considers the FLEs’ role more comprehensively.

      Authors: Alok Kumar Samanta , Varaprasad G. , Anand Gurumurthy
      Abstract: 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. 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. 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. 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. 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. 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.

      Abstract: 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. 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. The results of the study have been validated using fuzzy VlseKriterijumska Optimisacija I Kompromisno Resenje (VIKOR). It is found that the “cost” criterion is the most significant among other criteria with MDL weight of 0.3. Through fuzzy-GRA, out of ten identified CTQs, non-availability of rack system is found to be the most critical issue in assembly section of case industry. The perceptions of industrial manager and production head of case industry are strongly in favor of the obtained results and have implemented the suggested solutions. To sustain in the competitive environment and produce quality product at right time, organizations need to control their CTQs as per their criticality. For this, the decision-making becomes quite complex to select the most critical factors because of the fascinating nature of various criteria and sub-criteria. The present study is the first attempt that has implemented the multi-criteria decision-making approach in analyze phase of LSS project.

      Abstract: 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. 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). 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. 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. 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.

      Authors: Nikolaos A. Panayiotou , Konstantinos E. Stergiou
      Abstract: The purpose of this paper is the development of a reference model contributing to the identification of the retail supply chain activities that can be improved by the implementation of Lean Six Sigma (LSS) initiatives, following DMAIC steps and using proposed tools, based on contemporary technologies and best practices. The reference model was developed combining the existing literature knowledge about the areas of supply chain that LSS can improve and the data collected by two big retailers in Greece about their supply chain operation. The integration of two sources of information led to the modeling of the retail supply chain processes and the proposal of appropriate LSS initiatives for their improvement. This paper aimed to detect the pain points of a retail supply chain, which can be achieved by following the steps of DMAIC and applying specific LSS initiatives as described in the reference model, to introduce the trends of the sector in terms of logistics and supply chain. The reference model of this paper can be used as a comprehensive guide of LSS implementation in the retail supply chain and help the companies of such a significant sector for the economy. The literature review revealed that there is a lack of publications concerning LSS implementation in retail supply chain and in the retail sector in general. The development of this model contributes to the filling of this gap by providing a complete reference model, which strives to overcome the barriers of LSS adoption in retail supply chain.

      Abstract: 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. 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. 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. 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. 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.

      Authors: Carlos Alberto Escobar , Daniela Macias , Megan McGovern , Marcela Hernandez-de-Menendez , Ruben Morales-Menendez
      Abstract: Manufacturing companies can competitively be recognized among the most advanced and influential companies in the world by successfully implementing Quality 4.0. However, its successful implementation poses one of the most relevant challenges to the Industry 4.0. According to recent surveys, 80%–87% of data science projects never make it to production. Regardless of the low deployment success rate, more than 75% of investors are maintaining or increasing their investments in artificial intelligence (AI). To help quality decision-makers improve the current situation, this paper aims to review Process Monitoring for Quality (PMQ), a Quality 4.0 initiative, along with its practical and managerial implications. Furthermore, a real case study is presented to demonstrate its application. The proposed Quality 4.0 initiative improves conventional quality control methods by monitoring a process and detecting defective items in real time. Defect detection is formulated as a binary classification problem. Using the same path of Six Sigma define, measure, analyze, improve, control, Quality 4.0-based innovation is guided by Identify, Acsensorize, Discover, Learn, Predict, Redesign and Relearn (IADLPR2) – an ad hoc seven-step problem-solving approach. The IADLPR2 approach has the ability to identify and solve engineering intractable problems using AI. This is especially intriguing because numerous quality-driven manufacturing decision-makers consistently cite difficulties in developing a business vision for this technology. From the proposed method, quality-driven decision-makers will learn how to launch a Quality 4.0 initiative, while quality-driven engineers will learn how to systematically solve intractable problems through AI. An anthology of the own projects enables the presentation of a comprehensive Quality 4.0 initiative and reports the approach’s first case study IADLPR2. Each of the steps is used to solve a real General Motors’ case study.

      Abstract: The purpose of this study is to present the implementation of Six Sigma in a solenoid valve manufacturing company in China. The project aims to reduce the solenoid valve defects, decrease the cost of poor quality, increase customer satisfaction and improve the long-term profitability of Company B. This paper follows the Six Sigma methodology: DMAIC (define, measure, analyse, improve and control) principle of case study research. Hysteresis, the key characteristic of a solenoid valve, is the main chance for quality improvement. This paper emphasizes the solution to the hysteresis problem. During DMAIC phases, the critical factors that affect hysteresis performance are identified for continuous quality improvement of solenoid valve manufacturing. The implementation of Six Sigma leads to a great quality improvement for the company studied in this paper. Control plans are made for good hysteresis performance. As a result, the first pass yield of solenoid valves has increased from 60% to 99.64%. The key hysteresis of the solenoid valve has shown a better performance. This study presents a solenoid valve industrial quality improvement case that demonstrates how Six Sigma and DMAIC methodology can be applied to reduce defects and achieve quality improvement in Company B. This study can be referred to for managers and engineers to undertake quality improvement programs.

      Abstract: This study aims to propose a conceptual model indicating the impact of Industry 4.0 (I4.0) technologies on lean tools. Additionally, it prioritizes I4.0 technologies for the digital transformation of lean plants. The authors conducted a questionnaire-based survey to capture the perception of 115 experts of manufacturing industries from Germany, India, Taiwan and China. The impact of I4.0 on lean tools, using analysis of variance (ANOVA). Further, the authors drew a prioritization map of I4.0 on the employment of lean tools in manufacturing, using the Best–Worst Method (BWM). The findings indicate that cloud manufacturing, simulation, industrial internet of things, horizontal and vertical integration impact 100% of the lean tools, while both cyber-security, big data analytics impact 93% of the lean tools and advanced robotics impact 74% of the lean tools. On the other hand, it is observed that augmented reality and additive manufacturing will impact 21% and 14% of the lean tools, respectively. The results of this study would help practitioners draw up a strategic plan and roadmap for implementing lean 4.0. The amalgamation of lean with I4.0 technologies in the right combination would enhance speed productivity and facilitate autonomous operations. Studies exploring the influence of I4.0 on lean manufacturing lack comprehensiveness, testing and validation. Importantly, no studies in the recent past have explored mapping and prioritizing I4.0 technologies in the “lean” context. This study thereby attempts to establish a conceptual model, indicating the influence of I4.0 technologies on lean tools and presents the hierarchy of all digital technologies.

      Abstract: Lean construction (LC) is an important strategy to improve the results of organizations in the civil construction sector. However, there are barriers that hinder the success of implementing LC. The literature presents many barriers, which makes it difficult to make a diagnosis about the presence of these barriers within an organization. However, if companies could identify the main difficulties, they would face to implement LC, they could prepare by strengthening their weaknesses. This paper aims to diagnose a small set of factors that identifies the most significant barriers that must be considered before implementing lean construction. This study comprises an exploratory factor analysis (EFA). For this, a questionnaire was developed based on an extensive literature search on the barriers that hinder the implementation of LC. Using this questionnaire as a data collection instrument, a survey was conducted that obtained 135 responses from managers working in civil construction in Brazil. EFA was conducted using SPSS software. This study identified seven critical factors for successful implementation of LC: degree of cooperation within the work teams, use of an adequate performance measurement system, occurrence of job delays, level of participation of those involved in the construction of decisions, degree of leadership openness, positioning in the face of news and problems in the flow of information. The barriers to implementing LC can be different depending on the social and economic context in which companies are inserted. This work was conducted in an emerging country. Thus, it would be important that the same be applied to managers from other countries in different contexts to verify if the result found here is confirmed. There are many works in the literature that address the barriers to LC culminating in an extensive list, whose complexity of operationalizing the identification of their presence in an organization, ends up becoming another barrier. Given the negative influence that these barriers have for the success of LC, this work sets out to convert this extensive list into a short list that is easy to understand and use.

      Authors: Akbar Rahimi , Akbar Alemtabriz
      Abstract: Given the need to simultaneously implement lean and agile (LeAgile) paradigms in supply chain, managers do not know which of these paradigms practices should be given priority. Not knowing this, not only will they fail to apply these paradigms properly, but they will also waste significant financial resources. The purpose of this paper is to investigate the relationship between the practices of LeAgile paradigms and their effects on the supply chain performance. Because the military products play a key role in national security enhancement, this research is done in the military product supply chain. Research methodology is an exploratory, mixed and descriptive one. In terms of its purpose, it is an applied research based on identifying and searching for practices and the use of interpretive equations. First, the authors identify the most important and implementable LeAgile practices in the form of importance feasibility analysis matrices. Then, using fuzzy interpretative structural modeling, a model is presented to show the logical relationships and hierarchy between paradigms, practices and their impact on supply chain performance. The research tool in both main stages of the research was the questionnaire completed by industrial and academic experts. The selection of experts was done purposefully. The results show that of total 100 practices introduced in the previous research for LeAgile supply chain, 21 practices in the lean and agility of the supply chain of military industries are important and implementable. The final model of this study illustrates the hierarchical relationships between 21 practices and its effect on supply chain performance key measures. This model shows that LeAgile paradigms are intertwined and their simultaneous implementation leads to improved supply chain performance. In this model, supplier-related practices play a driving and fundamental role and become a top priority for implementation. Military products variation in land, air and sea areas and the large number of industries in each sectors, forced us to select the only land area. Although the results of this research can be used in the air and sea areas, one cannot say that Implementation of this study by its presented model will fully lead to the military industries supply chain (SC) lean and agility in air and sea sectors. To the best of the authors’ knowledge, this is the first research on the SC legality in Iran’s military industry which tries to apply these two paradigms simultaneously in the SC and bridge the gap between theory and practice. Clustering LeAgile practices, based on two measures of importance and feasibility, and defining four strategies for implementing these measures, is a new approach to focus on deploying practices that are currently more feasible. Identifying a significant number of SC LeAgile practices (100 practices) and demonstrating the interactions between important and feasible practices in the military products SC are another innovation in this research.

      Abstract: Unsatisfactory level of construction materials quality has been a persistent problem for companies in construction. This study aims to describe the application of the Six Sigma methodology for improving the tensile strength in a Chinese reinforcement material manufacturing company. Six Sigma-based framework of define-measure-analyse-improve-control (DMAIC) methodology is adopted in this case study. During different stages, quality problems and critical factors are identified to improve the low performance of tensile strength and thixotropy of the impregnating resin. The results provide solid evidence that how Six Sigma can be successfully applied in reinforcement material manufacturing. Results showed that vacuum degree, reaction temperature and stirring rate are significant factors on tensile strength. Control plans for continuous improvements are suggested and implemented. Our study found that managerial assurance activities such as verification were less developed than equipment-related control activities. Besides, data management required further elaboration on integrated data and information systematically, thereby to enable the company to make informed decisions and to support continuous improvement. This study contributes to show a potential area in which Six Sigma DMAIC approach can promote to improve the tensile strength of impregnating resin. This case can prompt managers of the company to apply Six Sigma method to address complicated problems in other reinforcement material processes. Companies of construction and their suppliers can refer to this study when improving their manufacturing process.

      Abstract: The purpose of this study is to identify the practical implications of Lean, Six Sigma (SS) and Lean SS (LSS) in the public administration sector. Determining the key themes of these practical implications is also an aim of the present study. A systematic literature review (SLR) was conducted based on the databases of six well-known academic publishers, namely, Emerald, Elsevier/Science Direct, Springer Link, Taylor and Francis, Sage and Willey online. The review revealed 56 peer-reviewed journal articles published between 2004 and 2020. The “affinity diagram” was applied to group the practical implications of Lean, SS and LSS into logical themes. A plethora of practical implications of Lean, SS and LSS in the public administration sector are identified in the literature, examples of which are analytically presented. The analysis showed that the practical implications identified can be grouped into 14 meaningful themes, and these themes in turn into categories, formulating thus, a conceptual framework. The key themes that are supported in the literature by most references are the following: human factors involved in Lean/SS/LSS, Lean/SS/LSS benefits and Lean/SS/LSS implementation issues. Although several databases were used, some publishers might have been missed out in this SLR. The subjectivity in applying the “affinity diagram” is also a limitation of this study. Based on these limitations, further literature review studies can be designed. Twofold implications arise from the present study, meaning from the practitioner and the academic perspective. The practical implications identified as well as their meaningful themes revealed constitute useful guidelines for managers and decision-makers wishing to implement Lean/SS/LSS in the public administration sector and bridge their knowledge gap between theory and practice. Moreover, all the practical dimensions of Lean/SS/LSS included in the comprehensive conceptual framework formulated could serve as research avenues for academics. The application of Lean/SS/LSS in the public sector has not been widely reviewed, while the stream of literature focuses on limited issues (critical success factors, benefits, challenges, etc.). Moreover, SLRs in services and specifically in the public administration sector are fewer. Stimulated by this gap and the suggestions of other researchers for future studies, to the best of the authors’ knowledge, this study provides the first SLR which analyzes the practical implications of Lean/SS/LSS in the public administration sector and determines their key themes.

  • Integration of Six Sigma methodology of DMADV steps with QFD, DFMEA and
           TRIZ applications for image-based automated inspection system development:
           a case study

      Abstract: This paper aims to present the development of an automated inspection system (AIS) using an image-based analysis mechanism, called i-AIS. The development process of i-AIS used the Design Six Sigma (DSS) methodology. The steps of define, measure, analyze, design and verify (DMADV) are applied and integrated with specific analyses techniques of the quality function deployment (QFD), design failure mode effect analysis (DFMEA) and theory of inventive problem solving (TRIZ). The production process of adhesive tape is the focused case study in this research project, motivated by the high product defect rate complained by customers. The development process of i-AIS was divided into five standard steps based on the DSS methodologies of DMADV. One of the key processes in this development was to systematically identify the right and intended features of i-AIS. This was carried out based on the application of the QFD technique. Another important process was to further investigate the possible causes of i-AIS failure, to function as intended. This investigative process was carried out based on the DFMEA technique, while the solution to minimize the risk of the identified failures was obtained from the TRIZ method. The final prototype of i-AIS was then presented in the design step. Verification of the i-AIS prototype revealed its operation at an optimally intended mode that fulfilled the requirements of internal customers. Verification results also revealed that the sigma level has improved from 3.87 to 4.33. Meanwhile, the defect reduction rate is improved to 74.4% and downtime rate also recorded a significant improvement at 80.7% of reduction. The presented research work is carried out based on a customized case study. Although the proposed methodology can be applied to others cases towards design-based solution, some modifications maybe required based on to the unique features of the case study under consideration. The presented research project indicated that the proposed methodology was successful to facilitate a structured and systematic process towards defect identification, classification, evaluation and generation of a solution. The paper presents the development process of an AIS by considering comprehensive managerial aspects that are currently absent in the literature. An integrated DSS structure is proposed to systematically guide the development of i-AIS. The related managerial aspects such as identification of critical defects problem, customer requirement mapping, prototype design analysis and comparison measurements before and after i-AIS installation are considered in this research project.

      Abstract: The purpose of this study is to investigate the perceived effects between soft management practices, employee behaviours and the implementation of digital technologies in manufacturing plants, as well as how these relate to the emergence of digital waste. This paper uses case-based research. Data was collected in two large manufacturing companies based in Norway and Sweden through semi-structured interviews with two management representatives and four shop-floor employees. The data was used to evaluate 29 variables describing lean- and total quality management (TQM)-associated employee behaviours and soft management practices, in light of digital transformation. The results suggest that several variables were positively influenced by the digital transformation process. These were top management leadership, middle management involvement, employee education, corporate social responsibility focus, innovation, knowledge sharing, work-family balance, psychological capital, job satisfaction and career commitment. Training employees, creativity, discretionary effort, turnover intention and proactivity appear to be negatively influenced by digital transformation The findings also indicate that several soft management practices and employee behaviours were not only influenced by manufacturing digitalization but also themselves influenced the process. The potential for digital waste creation was also detected in several variables, including reward and recognition and training employees. Managers, practitioners and academics may learn about the importance of certain managerial practices and employees’ behavioural needs during the digital transformation process. The findings may help in prioritizing TQM and soft lean management practices and certain employee behaviours during the digital transformation and in creating awareness of digital waste. This study builds on several existing studies discussing the impact of digital transformation on soft management practices and employee behaviours. It provides insights from a lean and TQM angle and offers a means of prioritizing certain practices and behaviours during a digital transformation. This study also highlights the significance of digital waste.

      Abstract: Healthcare environments are highly complex and full of variation and inefficiency. However, variation and inefficiency can be measured and improved, providing better quality care at a lower cost. This study aims to report the application of Lean Six Sigma (LSS) in a haematology laboratory in a university hospital in Egypt. The authors used case study research. Applying the define, measure, analyse, improve and control phases of the DMAIC methodology together with lean tools, the problem was identified, the process mapped, the causes analysed and improvements implemented. Results show that LSS can be successfully implemented in challenging public sector healthcare settings. Management commitment, generating and implementing ideas from frontline staff, using a variety of quality tools and previous LSS training were all key to success. This is evidence that the LSS methodology is adaptable to any process, people or place. There are no publications on LSS implementation in health care in Egypt. This study demonstrates the successful use of LSS in a university hospital (public sector) in a developing country, sharing insight into the facilitators and barriers in a real context with others in the healthcare field.

      Authors: Bao Chao , Chaoyong Zhang , Yu Zhang , Hongfei Guo , Yaping Ren , Hao Zhang
      Abstract: This paper aims to provide feasible countermeasures for the application of lean manufacturing in automatic sand casting workshops to optimize production line balance. A production line balance optimization model for sand casting workshops is proposed. The value stream mapping (VSM) approach is applied to diagnose the problems in the production process. An optimization scheme is established based on eliminate, combine, rearrange, simplify and increase theory and Kanban management method. Further, simulation is done to compare current VSM and future VSM. After implementing the proposed model, findings indicated that the idle time of equipment was effectively reduced, the line of balance of the production line was increased by 44.7%, the production lead time was shortened by 60.3% and the production capacity was increased by 50.0%. Application of the optimization model in this study is limited to sand casting workshops that have realized automatic or semi-automatic production. This paper provides an optimization model for the implementation of lean manufacturing in sand casting workshops and provides a reference case that reflects the actual application of lean manufacturing tools in a real situation.

  • Soft and hard skills development in lean management trainings

      Authors: Ana Paula Lista , Guilherme Luz Tortorella , Marina Bouzon , Matthias Thürer , Daniel Jurburg
      Abstract: This study aims to investigate the impact of traditional teaching and active learning methods in lean management (LM) on the development of both soft and hard skills. Through a longitudinal study, team members from two different organisations (the administrative sector of a public higher education institution and a public teaching hospital), each adopting different teaching methods to support their LM trainings, were systematically examined at four moments during an 18-month period. How teaching methods impacted team members’ development and knowledge was then assessed using multivariate data analysis techniques. Results indicated that LM trainings can provide significant impacts when a combination of traditional teaching methods and active learning is adopted. Traditional teaching methods can be a good choice for learning hard skills depending on resources’ availability. However, it is recommended to include active learning methods to assist in the comprehension of more complex and abstract LM concepts (soft skills). Although there exists a large number of publications on the relationship between LM implementation and teaching methods, the number of studies that consider the development of both hard and soft skills is rather limited. This study complements the existing literature on LM by identifying which teaching methods can support the development of hard skills and which the development of soft skills. Such identification facilitates the work of both scholars wishing either to begin or to dig deeper into this sphere and practitioners pursuing the best outcomes from LM.

      Abstract: Lean distributed manufacturing (LDM) is being considered as an enabler of achieving sustainability and resilience in manufacturing and supply chain operations. The purpose of this paper is to enhance the understanding of how LDM characteristics affect the resilience of manufacturing companies by drawing upon the experience of food manufacturing companies operating in the UK. The paper develops a conceptual model to analyse the impact of LDM on the operational resilience of food manufacturing companies. A triangulation research methodology (secondary data analysis, field observations and structured interviews) is used in this study. In a first step, LDM enablers and resilience elements are identified from literature. In a second step, empirical evidence is collected from six food sub-sectors aimed at identifying LDM enablers being practised in companies. The analysis reveals that LDM enablers can improve the resilience capabilities of manufacturing companies at different stages of resilience action cycle, whereas the application status of different LDM enablers varies in food manufacturing companies. The findings include the development of a conceptual model (based on literature) and a relationship matrix between LDM enablers and resilience elements. The developed relationship matrix is helpful for food manufacturing companies to assess their resilience capability in terms of LDM characteristics and then formulate action plans to incorporate relevant LDM enablers to enhance operational resilience. Based on the literature review, no studies exist that investigate the effects of LDM on factory’s resilience, despite many research studies suggesting distributed manufacturing as an enabler of sustainability and resilience.

      Authors: Charnnarong Saikaew
      Abstract: The purpose of this study is to develop a practical method for training students how to conduct statistical analysis and do a course project in design of experiments (DOEs) course through the Web-based virtual catapult simulation. A step-by-step sequential DOE process for investigating the effects of controllable factors on quality characteristic responses was presented as a guideline for conducting a DOE course project. Each team was assigned to create an innovative teaching material and work on the term report by following the recommended guidelines for designing experiments through the Web-based virtual catapult simulation. Hypothesis was defined to test whether doing a course project based on this approach would impact students’ learning outcome. The Web-based virtual material was an alternative technique for interactive teaching that could improve students’ understanding and achievement in DOE course projects. There was a significant difference in student learning and understanding before and after doing on the course project through the Web-based virtual catapult simulation. The students had improved communication and teamwork skills after following the recommended procedure for practicing DOEs. Most students could effectively conduct designing experiments, carry out designed experiments, analyze data and gain valuable teamwork experience. After learning the DOE approach based on the catapult simulation, they enjoyed working on their course projects deploying to the innovative toys and other real-life situations with real measurements. The use of Web-based virtual material, including catapult simulation, was an alternative technique for interactive DOE teaching to improve the students’ understanding and achievement in DOE course projects.

      Abstract: The importance of a lean health-care supply chain is increasingly discussed. However, it is still not very clear how lean practices relate to resilience capabilities, as there are synergies and divergences between them. This study aims at identifying the relationship between lean practices and resilience capabilities in the health-care supply chain. This study conducted a scoping review based on five databases, which allowed the content analysis of 44 articles. Such analysis allowed the verification of trends and volume of studies on this topic. Further, the descriptive numerical and thematic analyses enabled the proposition of a conceptual framework, relating the adoption of lean practices to the development of resilience capabilities according to the tiers of the health-care supply chain in different value streams. Three research directions were derived from this scoping review: empirical validation of the contribution of lean practices to resilience capabilities in the health-care supply chain; systemic implementation of lean practices across tier levels of the health-care supply chain; and complementary approaches to lean implementation toward a more resilient health-care supply chain. The understanding of these relationships provides health-care managers arguments to prioritize the application of lean practices to improve desired resilience capabilities in the entire health-care supply chain. To the best of the authors’ knowledge, there is no similar study in the literature.
