Authenticity is a central aspect and prominent feature of heritage tourism. Both practitioners and researchers are interested in the authenticity of tourism experiences when it comes to heritage tourism planning, marketing and management. The paper aims to explore the intervening role of tourist experience in the link between cultural heritage authenticity and place attachment and revisit intention, in the context of Egyptian cultural heritage sites. An integrative model was developed to explore the importance of cultural heritage authenticity and its influence on place attachment and revisit intention, through the mediating role of tourist experience. Using Smart PLS 4, data collected from 389 international tourists who visited Egypt were analysed. The findings of the study highlighted that tourist experience fully mediates the relationship between cultural heritage authenticity and both place attachment and revisit intention. The results also identified the positive direct effect of cultural heritage authenticity on tourist experience. The positive direct effects of tourist experience on place attachment and revisit intention were also significant. Findings hold important implications for both the research community and destination management and marketing organizations and heritage sites. Practical implications and potential future research are also discussed.
The purpose of the research study was to explore the Influence of Implementation of Quality Management Practices (QMP) on Operational Performance (OP) of Technical and Vocational Education and Training (TVET) Institutions in Sri Lanka and the study focuses on North Central Province (NCP). QMP can be defined as a systematic approach to improvement of quality in organizations business processes. The aim of improving the performance is all about of its service quality, profitability, customer satisfaction, and productivity. The TVET includes the process of skill-development of the workforce working in the industry of a country. After the implementation of QMP in the organizations then later organizations' management faced an issue, that there is a problem of low operational performance in (TVET) Institutions in many provinces. In the research study participated 202 students in many trade courses at TVET Institutions in NCP and a questionnaire used to gather data of QMP in the institution, student satisfaction and service quality. The results were analyzed using the SPSS software and used descriptive analysis, multiple regression analysis, correlations and t-test as analytical tools. Results revealed that there is a poor relationship between operational performance and customer focus and communication. However, the QMPs such as Employee Involvement and Continuous Improvement verified strong and significant relationship. It indicates that these TVET Institutions are not properly applying the QMP such as customer focus and communication in their institutions. Furthermore, this study recommended that TVET Institutions have to improve more on customer focus and communication.
This research assesses the lean and green (LG) practices' impact on the competitive advantage (CA) of organizations, through sustainable performance, considering lean maturity as the moderator. A structured questionnaire was used to collect data from a cross‐sectional sample of 261 companies operating in Portugal. Hypotheses are tested through structural equation modeling and multigroup analysis to examine the lean maturity moderating role. Results demonstrate a positive impact of LG practices on sustainable development and that their three dimensions of CA, with lean maturity boosting most relationships. This research highlights the impact of LG practices on organization's competitiveness and helps them underpin the importance these practices when comes to enhance their sustainable performance and their CA with help of environmental policy and also stakeholder engagement. Future studies should address these relationships upon a specific dimension, namely the correlation between environmental performance and CA, as it was not dealt in this study.
Due to extensive industrial activities, many environmental challenges have devastated human beings and environmental integrity. Therefore, sustainable supply chain (SC) practices (lean, green, and agile — LGA) gained momentum in the manufacturing industry. Considering the importance of LGA-SC, this study investigates the impact of LGA-SC practices on green innovation (GI), supply chain competitive advantage (SCPA), supply chain responsiveness (SCR), and sustainable firm performance (SFP). Data were collected from employees of the manufacturing industry in China. The proposed conceptual framework was verified by using structural equation modeling. The empirical results indicate that LGA-SC practices are statistically associated with GI, SCR, SCPA, and SFP. Moreover, this research finds that GI and SCR play mediating roles between LGA-SC practices and SCPA. GC positively moderates the relationship between LGA-SC practices and GI, and IP also acts as a strong moderator between GI and SCPA. To the authors’ best knowledge, this study is the pioneer to provide insights about a novel framework combing LGA-SC practices, SCPA, and SFP with mediating role of GI and moderating role of GI and IP. This study supports managers of the Chinese manufacturing sector to further extend strong roots for LGA-SC adoption.
The integrated implementation of lean and green systems can assist managers in achieving environmental and economic performance. The benefits of this integration include improved quality of the environment, superior interactions with channel partners and consumers, reduction in lead times and overall costs, and so forth. This research seeks to evaluate the solutions for integrated implementation of green and lean practices to overcome the barriers in the manufacturing industry. The barriers are categorized as managerial, technological, organizational and cultural, individual and quality barriers. In this study, a fuzzy AHP and fuzzy TOPSIS based framework has been proposed. From the analysis, it is found that application of quality control tools, reduction in lead‐time, use of right first time approach and use of new technology and product innovations are the most significant among the solution alternatives that the manufacturing firms should consider to overcome obstacles in implementation of green and lean systems. To the best of authors' knowledge, this is the first study to examine prominent solutions to overcome barriers with regard to integrated operation of green and lean performance. The ranking of the solutions will be useful for managers in the manufacturing firms to make best strategic decisions for reducing their waste and improving performance. Mangers can concentrate on the most prominent solutions and formulate the appropriate strategies accordingly.
Sustainable development is becoming increasingly crucial for the green aviation industry. To promote the sustainable development of the green aviation industry, researchers all over the world have attempted to explore and experiment with new initiatives. This study investigates green aviation industry development trends by a bibliometric‐based data analysis system. Cluster, timezone, and timeline visualizations are employed to identify the current development trends of the green aviation industry within three topics: noise, environmental impacts, and green image. In response to environmental challenges, an integrated green aviation industry support system that involves stakeholder engagement should be established, including business strategies, innovative technologies, environmental policies, and public support. In this study, the innovation and sustainability potential of the green aviation industry is evaluated. Then, the roles of strategy improvement, technology integration, policy support, and public participation in forming the integrated support system are examined. The outline of this system may prove helpful for the sustainable development of the green aviation industry.
Aviation plays a crucial role for economic development and social welfare, but at the same time it also significantly contributes to climate change. Therefore, if the industry wants to follow the same growth path as it has in the past, it will need to mitigate its environmental impacts more seriously or it may otherwise face regulatory restrictions. The current literature has discussed five mitigation strategies. These are technological changes, market-based changes, operational changes, regulatory changes and behavioural changes. While several authors have regarded behavioural changes as the measure with the greatest mitigation potential, it is also the measure that has received far less attention in the literature. The purpose of this study, therefore, is to investigate the potential of behavioural change as an instrument to mitigate the environmental impacts of aviation. The study is conducted in the form of a literature review. We first discuss issues related to the consumer's environmentally responsible self-concept that often conflicts with the environmental impacts of flying, the so-called flying dilemma. We then provide an overview of aviation's environmental impacts and present the five mitigation strategies in greater detail. After that we have a closer look at the concept of behavioural change. We then discuss separately measures of behavioural change from the perspective of the aviation industry and the air passengers. While the literature on the aviation industry presents many opportunities in which airlines can engage in behavioural change, the literature on air passengers is rather limited and focuses mainly on carbon offset. We instead have chosen another stream of literature that focuses on the novel idea of air passengers engaging in behavioural change by actively selecting airlines which are more environmentally friendly. We conclude this literature review with a discussion of how to bring green offer and demand together by drawing the conclusion that, in order to be able to mitigate the climate change impacts of aviation through behavioural change, an instrument to connect both ends would be needed.
Purpose
The key objectives of this study were to investigate the interactions among the lean, green management practices and organizational sustainable performance measures and explore the possibility of simultaneous implementation of these concepts for improving the organizational sustainable performance.
Design/methodology/approach
Using the interpretive structural modeling (ISM) technique, the interactions among the lean, green practices and organizational sustainable performance measures were established. A focus group which consisted of purposively selected 15 experts was utilized in the primary data collection.
Findings
In Sri Lankan context, water and material consumption reduction, energy efficiency, water pollution and greenhouse gas reduction were identified as the dominant green practices, while pull production, lot size reduction, continuous improvement, preventive maintenance, employee involvement and cycle time reduction were the dominant lean practices. Inventory level, profitability, quality, cost, employee satisfaction, customer satisfaction, lead time, resources consumption (material, water, energy) and waste generation were determined as the dominant sustainable performance measures. The resulting ISM-based structural model which consisted of eight levels concluded that firstly lean practices influence the green practices and afterward green practices affect the sustainable performance measures.
Research limitations/implications
The aim of this study was to develop a hypothetical structural model to explain the interactions among the lean, green management practices and organizational sustainable performance measures. But this hypothetical model was not empirically tested in the current study. So further study is required to empirically test the proposed model.
Practical implications
Currently organizations who practice for sustainable performance engages, lean and green practices separately without understanding on which practices are stared when and how. So, through the findings of this study, organization who desire to improve the sustainable performance are recommended to begin the journey with lean practices and subsequently move in to green and handle both lean and green initiatives through one functional unit.
Originality/value
The existing literature does not possess a model for explaining the lean–green synergy and organizational sustainable performance and this study successfully fills this gap. Also the study proposes for the practitioners, when and how the lean and green practices should be initiated and implemented for rising the sustainable performance of an organization.
The current rapidly changing and highly competitive market has put companies under a great pressure towards adopting sustainable practices, in terms of keeping a healthy balance among economic, environmental and social performances. In this context, the lean-green manufacturing approach, which combines lean practices focused on customers’ demand, and green practices focused on reducing the business’ environmental impact, has gained popularity. Nevertheless, the lean-green manufacturing is still a relatively new practice, lacking a clear and structured research definition, and of significant evidence of successful cases in the practice. In this paper, a literature review is conducted to identify the actual possibility of combining lean and green practices, the current trends for implementing such combination and the potential sustainability improvements such implementation can lead. It is the authors’ intention that the findings analysed in this paper can contribute to the state-of-the-art of lean-green manufacturing and provide practitioners with a useful tool towards developing effective strategies for its deployment.
The hospitality industry faces the challenge to decrease or eliminate their costs and to be more efficient in the near future. In recent years, the hospitality industry showed growth continuously, applicability to implement Lean in the hospitality and tourism sectors to improve productivity and service quality. Nevertheless, the literature review highlighted there are little hotels and tourism organization implemented Lean in their operation. Reason for that, Lean technique used in a single department of the establishments, which lead to missing the overall approach of Lean. Globally, the implementation of Lean techniques has proven to be successful in improving quality while reducing turnaround times and costs within the hospitality industry. There appears to be limited publicly available current research regarding Lean implementation in Egyptian hotels, leading to the motivation for this study. Therefore, the aim of this paper is to identify the application of Lean principles in Cairo five-star hotels in Egypt. This research adopted a quantitative approach to achieve the aim, objectives. A questionnaire was used for data collection. 72.5% was the average response rate. Statistical Package for Social Sciences (SPSS, version 16) program was used for analysing data. The results indicated that awareness and knowledge of the hotel participants about Lean term not clear for them and they did not know its meaning. The results showed that hotels did not implement Lean principles in their operations. A major contribution of this research is related to enhance the understanding of Lean principles. This research added to the growing Lean principles literature through its review of the previous academic research, generation of new ideas and interpretation of rich data collected from the different sources.
This study was conducted with an objective to understand the role of green human resource management (GHRM) in fostering environmental performance of employee. Specifically, it examines the impact of GHRM practices on employee green performance behaviors (task related and voluntary) with organizational identification as a mediator and employee personal environmental values and gender as moderators. Three hundred one employee from automobile sector in India participated in the study. Using cross‐sectional research design, the proposed research model was tested with the help of hierarchical regression analysis. GHRM was found to significantly predict both task‐related and voluntary employee green behaviors. Organizational identification significantly mediated the effect, whereas gender and environmental values failed to moderate the relationship between GHRM and employee green behaviors. The study signifies the role of HRM in achieving environmental sustainability and emphasizes on the urgent need to embed sustainability dimension into HR systems to achieve sustainable development goals.
Nowadays, Lean Manufacturing, Industry 4.0, and Sustainability are important concerns for the companies and in a general way for the society, principally, the influence of the two production philosophies, Lean Manufacturing and Industry 4.0, in the three main pillars of sustainability: economic, environmental, and social. According to the literature review done in this work, these relations are not well known and are dispersed by different sustainability’s criteria. To address this gap, this research proposes a structural equation model, with six hypotheses, to quantitatively measure the effects of Lean Manufacturing and Industry 4.0, in Sustainability. To statistically validate such hypotheses, we collected 252 valid questionnaires from industrial companies of Iberian Peninsula (Portugal and Spain). Results show that: (1) it is not conclusive that Lean Manufacturing is correlated with any of the sustainability pillars; and (2) Industry 4.0 shows a strong correlation with the three sustainability pillars. These results can contribute as an important decision support for the industrial companies and its stakeholders, even because not all the results are in line with other opinions and studies.
Effective hotel supply chain management has burgeoned as a potentially valuable means for achieving competitive advantage and improving organizational performance. Competition between hotels has recently expanded to include competition between supply chains. Major businesses around the world have realized the value that lean management philosophy can bring to their supply chains. Lean is a systematic approach that is presently argued to be adopted to optimize the entire supply chain management by eliminating wasteful activities (time, effort and materials), increasing product flow efficiency, reducing inventories, and enhancing customer fulfillment and satisfaction. The aim of the current study is twofold. Firstly, it aims to assess the current level of awareness about lean management within the hotel sector in Egypt, as a point of reference to evaluate the readiness of this sector to implement the lean concept in the management of their supply chains. Secondly, it further attempts to propose a framework to facilitate the implementation of lean in the management of hotel supply chain. A quantitative methodological approach of a questionnaire has been conducted with senior managers in five-star and four-star hotels in Egypt. Findings indicated that hotels in Egypt are somewhat aware of the terms like, for example, lean management, lean thinking, or lean principles, though more emphasis is needed on how to effectively implement lean tools in the management of hotel supply chains. Lean awareness status differed between five-star and four-star sub-segments. Overall, the results indicated that the hotel sector in Egypt has an adequate level of readiness to implement lean supply chain management (LSCM). It was shown that hotels already have in place certain practices that support this philosophy. Finally, a four-phase framework for effective LSCM implementation has been proposed.
Research Summary
We used interviews with elite informants as a case study to illustrate the need to expand the discussion of transparency and replicability to qualitative methodology. An analysis of 52 articles published in Strategic Management Journal revealed that none of them were sufficiently transparent to allow for exact replication, empirical replication, or conceptual replication. We offer 12 transparency criteria, and behaviorally‐anchored ratings scales to measure them, that can be used by authors as they plan and conduct qualitative research as well as by journal reviewers and editors when they evaluate the transparency of submitted manuscripts. We hope our article will serve as a catalyst for improving the degree of transparency and replicability of future qualitative research.
Managerial Summary
If organizations implement practices based on published research, will they produce results consistent with those reported in the articles? To answer this question, it is critical that published articles be transparent in terms of what has been done, why, and how. We investigated 52 articles published in Strategic Management Journal that reported interviewing elite informants (e.g., members of the top management team) and found that none of the articles were sufficiently transparent. These results lead to thorny questions about the trustworthiness of published research, but also important opportunities for future improvements about research transparency and replicability. We offer recommendations on 12 transparency criteria, and how to measure them, that can be used to evaluate past as well as future research using qualitative methods.
There are far reaching repercussions of human industrial activities resulting in the extinction and endangering of many life forms. Upon realisation of this alarmingly increasing threat on its own survival, the human industrial activities have started to transform itself which has led to discussions on newer concepts like green management. Hence, this paper attempts to provide a basic overview of the concept of green management at the introductory level and discuss different types of green management strategies adopted by organisations. The paper attempts to contribute to the emerging field of green management and the stakeholders of sustainable development.
Purpose
This paper provides a comprehensive, yet concise, overview of the considerations and metrics required for PLS-SEM analysis and result reporting. Preliminary considerations are summarized first, including reasons for choosing PLS-SEM, recommended sample size in selected contexts, distributional assumptions, use of secondary data, statistical power, and the need for goodness-of-fit testing. Next, the metrics, as well as the rules of thumb, that should be applied to assess the PLS-SEM results are covered. Besides covering established PLS-SEM evaluation criteria, the overview includes new guidelines for applying (1) PLSpredict, a novel approach for assessing a model’s out-of-sample prediction, (2) metrics for model comparisons, and (3) several complementary methods for checking the results’ robustness.
Design/methodology/approach
This paper provides an overview of previously and recently proposed metrics, as well as rules of thumb, for evaluating the results of research, based on the application of PLS-SEM.
Findings
Most of the previously applied metrics for evaluating PLS-SEM results are still relevant, but scholars need to be knowledgeable about recently proposed metrics (e.g., model comparison criteria) and methods (e.g., endogeneity assessment, latent class analyses, PLSpredict) and when and how to apply them.
Research limitations/implications
Methodological developments associated with PLS-SEM are rapidly emerging. The metrics reported in this paper are useful for current applications, but scholars need to continuously seek the latest developments in the PLS-SEM method.
Originality/value
In light of more recent research and methodological developments in the PLS-SEM domain, guidelines for the method’s use need to be continuously extended and updated. This paper is the most current and comprehensive summary of the PLS-SEM method and the metrics applied to assess its solutions.
The airline services industry suffers from high cost, waste management and environmental pressures, along with a competitive business environment. The lean and green (L&G) paradigm is a fusion of the well-established management concepts of lean thinking and green management and creates synergies between these concepts to produce heightened cost reducing and environmentally friendly benefits. The purpose of this generic qualitative research study was to explore the L&G paradigm's drivers, barriers, and practices among seven airline operators in the South African airline services industry. This was completed through 12 semi-structured telephonic interviews. This study found that airline operators are mature in their adoption of the L&G paradigm, with L&G practices focused around fuel efficiency and weight reduction. The drivers of lean adoption are regulatory requirements and a competitive operating environment, while the barriers are inherent service interruptions, a 'lean limit', and money market volatility. The major drivers of green management adoption are well-developed regulations and a fear of future regulations, while the barriers are a price focused consumer market and issues with efficient technology adoption. Academically, this study identified that firms may have unique 'lean limits', and highlighted the possible application of the L&G paradigm in a service-context by corroborating findings reported in the manufacturing-based literature. Practically, the findings can assist managers to identify where the 'lean limit' exists in their firm and to begin actively incorporating green management into their objectives rather than enjoying environmental benefits as a spill-over benefit from lean initiatives.
Productivity, profitability and sustainability have become the essence of business survival; thus, modern industrial establishments are turning into frameworks consistent with environmental objectives by adopting cleaner technologies, green practices have ultimately resulting in generation of fewer pollutants. Urbanization and burgeoning technological advancement in different sector within India have brought the concept of green supply chain management, to highlight the importance of responsible consumption and production to maintain environmental quality, reduce wastage and bring out economic growth. This paper aims to segregate the sustainable and competitive performers from the average ones in the Indian manufacturing sector and to understand the degree of the impact of green practices of supply chain management based on their contribution towards sustainable environment. Using survey method, data are collected from 54 manufacturing organizations from Pune Nashik area, and a comprehensive framework of sustainability measurement is developed through successive applications of Chi-square Automatic Interaction Detector analysis, CHAID analysis. This paper is unique as it has applied the concept of CHAID analysis for first time to identify green logistics as main driver to achieve a reduction of ecological damage and improve business performance.
The purpose of this study is twofold: to improve understanding on how the synergetic relationship between lean and green practices is operationalized and how innovative practices are fostered in workplace through integrated lean and green approaches. The Resource-based view (RBV) of the firm, and in particular, the concept of complementarity is used as a theoretical lens to achieve the purpose of the study. Following an inductive theory building approach using exploratory case study methodology in two manufacturing organisations in the UK, the authors conduct twelve semi-structured interviews with cross-functional team involved in integrated lean and green practices. The outcomes of the study evidence several examples of innovation fostered through synergetic lean and green implementation, though the integration requires customisation depending upon the operations profile of selected cases, e.g. high volume/low variety versus low volume and high variety setting. Our study also reported the possibility of creation of environmental value alongside economic value, e.g. eco-friendly products are cheaper to produce through integrated lean and green practices in design and service delivery processes. Cross-functional collaboration and collaboration with suppliers are key to promote innovation within operations and supply chains. Following a theory building approach, authors propose two testable hypotheses for future research.
The aviation industry is being challenged to combine operational efficiency with environmental excellence and without compromising safety. Recent work has proposed an integration of safety, and in particular, human factors, with lean operations (Ward and De Brito, 2007). This paper extends the previous work, by bonding green principles to the existing models. We propose an innovative Lean-Safe-Green Aviation Enterprise Model, incorporating lean-safe with green principles. This paper begins by grounding the rationale for such integration, highlighting its embeddedness in the sustainability paradigm. It then goes over the alignment of lean-safe with green principles and practices. The paper also provides an overview of tools on environmental impact and assessment and stakeholder engagement. The paper concludes by presenting the implications of lean-safe-green operations both for the aviation industry and for theoretical development. This research is under the umbrella of the HILAS (Human Integration in the Life-cycle of Aviation Systems) European project.
This study examines the relationship between the knowledge creation process and technological innovation capabilities, and analyzes their effect on a firm’s sustainable competitive advantage using a knowledge-based view theoretical framework. We conduct structural equation modeling analyses using survey data from 315 Chinese industrial firms to test the direct and indirect effects of the knowledge creation process on sustainable competitive advantage. Technological innovation capabilities—operationalized to reflect the dimensions of process innovation capability and product innovation capability—are used as the mediating variable for explaining the relationship between the knowledge creation process and sustainable competitive advantage. The results indicate that the knowledge creation process does not have a significant direct effect on sustainable competitive advantage. Rather, the knowledge creation process can only influence the sustainable competitive advantage through the mediating effect of technological innovation capabilities completely. Consequently, the knowledge creation process favors the development of technological innovation capabilities for processes and products, because processes and products can lead to a sustainable competitive advantage.
Competitive landscape, informed consumers and stringent regulations have forced many manufacturing small and medium-sized enterprises (SMEs) to focus on operational efficiency along with sustainability issues in recent years. While many manufacturing organisations have been taking lean initiatives for the past few years for operational excellence, an impulsive rush to adopt lean without a strategic deployment vision has led to scattered implementation of lean tools and projects without desired success. Many researchers and practitioners prescribe Value Stream Mapping as a foundation for lean transformation initiatives; however, little empirical work is available on the symbiosis of lean and green paradigms to reap maximum benefits. This research, through a systematic methodology and a novel tool called Green Integrated Value Stream Mapping (GIVSM), integrates both the paradigms in a case study on a UK packaging- manufacturing SME. Applying the GIVSM demonstrates that simultaneous deployment of lean and green paradigms have synergistic effect for improving both operational efficiency and environmental performance. In addition, continuous improvement framework with sustainable procurement is proposed to overcome the lean-green misalignments. This study also provides a guiding reference for practitioners to undertake similar improvement projects and identifies opportunities to expand this academic research on integrated lean-green approach into other industry sectors.
Purpose
This paper aims to examine the antecedents of green entrepreneurship intention (GEI) amongst tourism and hospitality higher education students and further explores the effect of green entrepreneurship intention on sustainable development (SD). It also investigates the mediating role of GEI in the relationship between the antecedents of GEI and SD in students' future tasks in tourism and hospitality.
Design/methodology/approach
Partial least squares structural equation modeling was used to analyze data collected via an online questionnaire from 970 tourism and hospitality universities' students in Egypt, either undergraduate or postgraduate.
Findings
The results show that green entrepreneurship intention is positively affected by attitude, subjective norms, environmental education, risk aversion, self-efficacy and environmental values. The results also revealed that green entrepreneurship intention is a significant driver for sustainable development. Moreover, the findings revealed that GEI mediates the link between the antecedents of GEI and SD.
Practical implications
The results offer highly persuasive insights that may be used to promote GEI and SD among tourism and hospitality students. The effectiveness of GEI in achieving SD will motivate government and educational institutions to develop GEI for university students. This study will assist policymakers in developing a novel strategy, providing a contribution to the green behavior literature in an emerging context.
Originality/value
The field of the green entrepreneur is uncharted and still in its infancy. As a result, further research is needed in the literature to better understand green entrepreneurship intention. Enhancing tourism and hospitality students' green entrepreneurial intentions will help the economy expand sustainably in the future because they are the entrepreneurs of tomorrow. The findings hold important implications for both the research community and tourism education and business management.
Aviation is one of the pivotal transportation modes that has a transformative impact on both social and economic production factors – mobility. Clearly, the aviation industry with its elements creates interaction between sustainability of both nations and organizations – economic, social and environmental ones. Moreover, the aviation industry supports the improvement of production mobility. In essence, the aviation industry may give more effective and efficient sustainable support to the business environment and sustainable development if it is lean in both operations and management.
Satisfying the requirements associated with environmental concerns and resource efficiency in the manufacturing process has become necessary to realize effective production management. Specifically, manufacturers must identify novel working procedures or methodologies to enhance the resource efficiency and environmental friendliness of production processes. Green-lean production and a circular economy are promising schemes to achieve this goal. However, compared to green-lean management, the implementation of a circular economy in production operations remains relatively unclear. Several scholars have recommended the combination of the circular economy and green-lean concepts to bridge this gap, however, systematic methods remain to be developed. Considering this aspect, this study proposes a method that integrates green-lean solutions with the circular economy concept. The proposed method is applied in production operations through the principle of continuous improvement to enhance the environmental and resource performance aspects. The method includes three successive phases, which can not only help managers fully identify the opportunities for improvement but also provide managers with directions for improvement by introducing four strategy quadrants. The effectiveness and practicability of the proposed method are proven considering an industrial case of the assembly workshop of an automobile company. The proposed study can support enhance theoretical knowledge regarding the green-lean and circular economy concepts and demonstrates the implementation of a circular economy in the process of optimizing the production operation of manufacturing enterprises.
Lean manufacturing has already proven to be an effective management philosophy for eliminating waste in production processes, leading to operational gains. However, nowadays, it is not enough just to obtain economic results, with the environmental aspect being a concern that organizations have been incorporating into their production processes due to stakeholder's pressure in order to increase their sustainable performance. As such, a bibliometric and a structured analysis of the literature were carried out focusing on the connection between lean, green and sustainability concepts. The Web of Science platform was used to collect data, encompassing the period from 1900 to 2020. The carried analyses covered the identification of the most relevant papers, including their authors, as well as their temporal and geographical distribution. There was also focus on the draft of a map to observe an underlying intellectual structure through VOSviewer. The novelty of this research is that, through the gathering of relevant data related to the three concepts considered and their analysis, a conceptual model was proposed consisting of lean-green and sustainability (LGS) tools to achieve superior triple bottom line (TBL) performance. This study pinpointed that in most of the cases where LGS tools have been applied (TPM - Total Productive Maintenance - and 6R, e.g.), there was a positive impact mostly on the economic and environmental pillars of the targeted companies. Although there were also a small number of other cases where it was found that an improved efficiency induced an increased consumption of energy and water, namely by lean tools (SMED - Single Minute Exchange of Dies, e.g.), the results demonstrated the capability of lean and green, especially their combination, to enhance sustainability outcomes. Future research should focus on quantifying the effects that LGS tools, in a single way or combined, bring to all TBL pillars, especially the social one, e.g., by developing key performance indicators. The testing of the proposed conceptual model, including its completion, is also encouraged, namely through the evaluation of what is the best combination of LGS tools, considering specific sectors of activity.
The fundamentals of the blue economy promoting sustainable development by minimizing the consumption of fresh water, organic pollution and chemical contamination. On the other hand, the six sigma tool enables companies to improve the performance of their processes by reducing waste and statistical techniques. Not many works have been identified that related these two approaches, therefore, the objective of this work is to apply the six sigma tool with the blue economy fundamentals to assess the economic and environmental performance in the aircraft refueling process. The methods used were Return of Investment (ROI) and Mass Intensity Factor (MIF). A multiple case study was carried out involving two largest Brazilian airlines and the fuel distributor. The main results show the reduction of flight delays and, consequently, a decrease in the diesel consumption by trucks and energy generators, and water. The calculated economic gains were 52.9 million dollars annually and the environmental gains were the non-generation of 150 thousand tons annually. This work contributed to the theory for being the first to link SS in Aviation with measuring environmental benefits, even more so through the Blue Economy and to the practice for presenting to managers the possibility of obtaining economic and environmental benefits in the aircraft refueling process with no investment.
The purpose of this paper is to explore the concept, types, and causes of food production failure (FPF) in restaurant kitchens from the perspective of chefs. Employing a phenomenological epistemology, a qualitative methodology was adopted to explore FPF. Extant literature was reviewed. Using purposive sampling, and employing an emic posture, 15 semi-structured interviews were conducted with senior restaurant and hotel chefs until saturation occurred. Interviews were transcribed, read repeatedly, and coded using the qualitative analysis software package QDA Miner Lite. An inter-rater reliability score of .78 using Cohen’s Kappa coefficient formula reflected substantial agreement between coders. Thematic analysis was used. The study revealed three main categories of FPF types (sensory/organoleptic, safety, other) and FPF causes (People related failure; Operation-related failure; and Food supply/supplier-related failures). A conceptual model was developed from these categories underpinned by management control systems, continuous training, clear communication, and the organizational culture and climate of kitchens. Chefs found that FPF was inevitable based on human error, and can be precipitated by certain factors but reduced by other interventions. Research findings may assist in reducing its frequency, thereby increasing customer satisfaction and retention while reducing financial and environmental costs of FPF. Practical, theoretical, and managerial implications are discussed.
Recent reports on environmental protection have found that lean management can facilitate green operations in container terminals. Using data from 268 samples in Kaohsiung, a structural equation modeling approach was employed to examine the relationships among lean management, green operations, and green behavior with respect to green performance, and a hierarchical regression approach was utilized to test the moderating effect of green climate between these major dimensions in the context of container terminals. The research findings indicated that lean management positively influenced both green operations and green behavior. Green operational practices had a positive impact on both green behavior and green performance. Green climate also had a positive effect on green performance. Additionally, a green climate positively moderated the effect of lean management, green behavior, and green performance. In this era of environmental protection, these research outcomes have practical implications for the expansion of container terminal organizations by improving operational effectiveness with green performance.
The adoption/utilisation of Lean, Agile and Green (LAG) practices in both the manufacturing and service sector is rising. However, there yet remain a research gap to precisely evaluate the relationship between LAG practices and business competitiveness (e.g, achieving reduction in cost, lead time and environmental recyclable waste). This research aims to explore this relationship, specifically in fast-moving consumer goods (FMCG) businesses. The hypothesised relationships are tested with data collected from 96 FMCG companies. Structural Equation Modelling is applied to evaluate different channels of achieving business competitiveness through the adoption of Lean, Agile and Green. The findings suggest that competitive outcomes vary with the adoption of LAG practices in specific product life cycle stages. This implies that awareness of the product life cycle concept is essential. A combination of LAG practices for the sole purpose of reducing environmental waste is negatively related to environmental waste reduction. LAG practices are more efficiently adopted when the adopters are equipped with expert knowledge on the paradigms and their individual practices. This research has approached the attainment of competitiveness in the FMCG businesses by analysing management efforts that improve cost performance, lead time and environmental sustainability aspects of business operations. The research has also considered the product life cycle stages in analysing the impacts of management efforts.
This study primarily assesses a conceptual model that links green logistics management practices with social, environmental, market and financial performances to examine its capability in achieving sustainable performance. The study examines the direct influence of green logistics management practices on environmental, social, market and financial performances. Further, the mediating effects of environmental performance, social performance and market performance between green logistics management practices and financial performance are examined. The study uses dataset gathered from 240 firms across three industries (entertainment, manufacturing and logistics) using structured questionnaires. The structural equation modelling partial least square (Smartpls software 3.2.8) is used to simultaneously test both the direct and indirect relationships between the variables. The results indicate that green logistics management practices has significant positive influence on environmental performance while it insignificantly influences social, market and financial performances. Besides, environmental performance mediates green logistics management practices and financial, social and market performances, while social performance fails to mediate the influence of both green logistics management practices and environmental performance on financial performance. This study expands literature by obtaining the results for the conceptual model and dealing with the implication from the Ghanaian perspective, which is a lower middle-income economy to strike a balance between knowledge. The study reveals that the adoption of green logistics management practices has little influence on improving the social welfare and health of the society and employees while it improves financial performance through environmental and market performances.
Due to growing awareness about environment protection, firms are forced to implement environmental practices to enhance their green image. Sustainability and green branding have seen special interest from different business disciplines including information management, marketing, supply chain management, etc. The growing concern for environment and related issues owed by economic and ecological impact. The aim of this paper is to identify and analyse the critical success factors (CSFs) of green manufacturing (GM) behind successful achievement of environment sustainability in Indian manufacturing industry. In this research, CSFs of GM and its sub-factors derived from extensive literature review. The reliability of these factors was checked by calculating the Cronbach’s alpha. The pair-wise comparison method of analytical hierarchy process (AHP) was used for finalisation the priority of CSFs after calculating the internal consistency. This key area for improvement recommends the set of measures for improving the implementation of GM practices in Indian organisations. This study result has realised the identification, interaction, weightage and rank of identified CSFs of GM in Indian manufacturing industries. The SAP-LAP analysis and construct validation of three case studies are carried out. This validation has examined the extent and effectiveness of proposed GM framework in Indian context.
Recently, social media has emerged as a relatively low-cost option for all restaurants that offers more opportunities for monitoring performance than traditional types of media. To date, social media research related to restaurants has often emphasized how to implement social media as a promotional tool and communication device and has focused on larger, chain restaurants or on the consumer perspective. In this study, we apply the resource-based view theory to specifically explore the managerial side of monitoring social media in small restaurants by interviewing people in charge of it. We interviewed eighteen restaurants and specifically asked them about their challenges and successes of using social media as a monitoring tool to explore how they can better utilize social media. We discovered that due to an array of challenges, most small restaurants underutilize social media as a monitoring device in their operations. We suggest ways this can be addressed even with the limited resources small restaurants may have.
In the last decades, sustainable development has increasingly gained importance to service industry and the integration between Green, Lean and Six Sigma approaches in service systems is necessary in order to balance the need for operational efficiency with environmental commitment and social fairness. Because of that, the purpose of this paper is to critically review the Lean and Lean Six Sigma (LSS) methodologies and highlight their importance to achieve sustainable services. To do this, a systematic literature review of the subjects under investigation was conducted. The study has two major contributions. First, it is one of the first researches that examine the compatibility and divergences of Green, Lean and Six Sigma concepts and implications regarding its sustainable implementation in service industry. Second, it provides a holistic Green LSS framework attempting to help practitioners to find ways of institutionalizing it in numerous kinds of services, by pointing out nine critical factors for its implementation, such as continuous customer satisfaction, ethical relations and regulatory compliance, focus on knowledge management and human behaviors, and effective Jidoka automation. The proposed framework indicates new paradigms and pathways to achieve the balance in technical, economic, social and environmental priorities in services.
Purpose
The purpose of this paper is to empirically assess the impact of integrated lean and green practices on the sustainable (environmental, economic and social) performance of a hotel supply chain.
Design/methodology/approach
Literature review and previous exploratory studies were used to develop a hypothesized model that characterizes the integrated lean and green (LeGreen) impact on supply chain sustainability. A case study of a large sample of the UAE hotels is used to collect and analyze empirical data, validate the measurement model and test study hypotheses using structural equation modeling (SEM).
Findings
The results showed that three major lean techniques (Kaizen, quality and productive maintenance) and three green techniques (health and safety, waste disposal and green certifications) have substantial impact on the sustainable performance of hotel supply chains. Further results revealed that LeGreen impacts are complementary. Lean techniques have the highest impact on the economic performance of the hotel supply chain and the least impact on the environmental performance. Green practices, on the other hand, have opposite impacts.
Research limitations/implications
Although the study findings may vary in different contexts, study methodology and measurement model can be adapted to assess the LeGreen impact on the sustainable performance of hotel supply chains, as well as other service industries such as banking and health care.
Practical implications
The proposed assessment model is expected to be of great value toward the effective implementation of LeGreen practices across hotel supply chains in the UAE and globally. The study findings also provide guidelines for practitioners within the hospitality sector to undertake the proposed model and to adapt it for assessing and enhancing sustainable performance in other sectors of the service industry.
Originality/value
There is a growing emphasis by practitioners and academics on measuring the impact of LeGreen on the sustainable performance of service supply chains. However, the assessment of LeGreen impacts within the context of a hotel supply chain remains unexplored with a scarcity of comprehensive assessment frameworks. This study aims to fulfill this gap in literature and provide directions for researchers to expand the proposed model and to further analyze the integrated lean-green impact on the sustainability of supply chains of hotels and the service industry.
Although researchers recognize the synergy between lean and green manufacturing, the concepts around this topic remain unstructured. When it comes to performance assessment, the elements that allow evaluating the integrated performance of lean and green are still unknown, since each separate system (lean and green) has a specific logic to assess performance. Thus, this paper systematizes the available knowledge about the relationship between lean and green to identify how these practices relate to performance criteria and how they could be integrated into a unique assessment system. To achieve this goal, we applied a systematic review aiming to extract the main contributions and gaps from the lean and green literature. The systematic literature review was conducted in two stages: selection and analysis of the studies. After selecting a set of 65 articles, the paper provides an overview of the literature trends regarding journals addressed, most cited papers, applied methods, and current research streams. Then, through a content analysis of the articles, the paper identifies the performance criteria and practices of lean and green and their relationships. Based on the main findings, we proposed a conceptual framework that helps in understanding the concepts and relationships involved in the lean and green performance assessment system. From the literature review and inspired in the framework, we suggested some possible research questions for further investigation.
Purpose
Developing agility and innovativeness as dynamic capabilities are important for firms to sustain their competitive advantage in today’s global economy. The purpose of this paper is to develop and empirically test a framework to investigate how the supply chain agility and innovativeness are achieved through IT integration and trust in members of supply chain and how these, in turn, can enhance firms’ competitive advantage.
Design/methodology/approach
This research employs a survey method and data are collected from senior managers working in the supply chain or IT area. The model and hypotheses are tested utilizing data from 204 usable Taiwan manufacturing firms via structural equations modeling methodology.
Findings
The study demonstrates that both IT integration and trust in supply chain members significantly enhance supply chain agility and innovativeness, which in turn positively affect firm’s competitive advantage. The results indicate that IT integration and trust are antecedents and major joint partnership resources for improving supply chain agility and innovativeness.
Research limitations/implications
Data are collected from manufacturing industry in Taiwan and single respondent from each firm, the generalizability of current findings to other industries or countries should require additional investigation.
Practical implications
The study suggests that a firm should focus on IT integration and trust in supply chain members to achieve supply chain agility and innovativeness. To take advantage of supply chain agility and innovativeness, through maximizing firm’s competitive advantage, firms should continually adapt to the fast changing business environment and search for creative ways to satisfy new market needs.
Originality/value
Given the attention paid to supply chain agility and innovativeness in terms of importance to responding to business uncertainty and competitiveness, and more recently, as important capabilities in managing supply chain management, this paper investigates how IT integration and trust can contribute to supply chain agility and innovativeness. Provide evidence regarding the impact of IT integration and trust on agility of supply chains, innovativeness and competitive advantage.
This paper investigates the relationship between lean, green and process innovation practices and green supply chain (GSC) performance. Data were collected from 374 manufacturing firms and results analyzed using Structural Equation Modeling (SEM). The findings revealed a synergetic effect between process innovations, green and lean practices, which play a crucial role towards the improvement of GSC performance. In particular, the results suggested that: (1) lean practices such as JIT, set-up time reduction, cellular manufacturing, and waste elimination can significantly contribute to improve GSC performance; (2) green practices including eco-design, life cycle assessment, green manufacturing, reverse logistics, and waste management significantly and positively affect GSC performance; (3) process innovation practices such as fast response to new processes introduced by other companies within the same sector, pioneering disposition to introduced new processes, and number of changes in the process introduced in one year, do not have a direct contribution to improving GSC performance; finally that
(4) process innovation amplifies the effect which contributes for lean and green practices to offer a higher payoff rate in terms of GSC performance when these are coupled with process innovation activities. This paper presents an innovative approach since it studies simultaneously the three dimensions of sustainability (environmental, social and conomic), the lean, the innovation process and green paradigms, which are considered strategic for supply chain competitiveness. Investigating the relationships between the four strategies is a contribution that the authors hope will become a forward step for promoting sustainability in manufacturing supply chains.
Lean manufacturing practices (LMPs) and corporate environmental sustainability are becoming inextricably linked. Throughout the lean and green debate, many organisations have recognised that LMPs have implications for their sustainable development and competitive positioning. Not only LMPs are complex on their own, but when perceived from an environmental sustainability perspective, the decision to implement an LMP can become even more intricate. Although general tools exist, the lack of effective decision-making tools to help in the implementation of LMPs with an environmental sustainability dimension is palpable. Thus, this study tackles the aforementioned decision problem by incorporating environmental and operational performance outcome expectations as these expectations are viewed in light of the ease of implementation of various LMPs. A novel multi-criteria decision-making (MCDM) model for evaluation of LMPs is developed in this respect. The model integrates a three-parameter interval grey number with rough set theory and the TODIM method. The model is run using empirical data from six manufacturing organisations. The findings facilitate the identification of a ‘locus of investments’ for a better selection of LMPs. The robustness of the decision support model developed is assessed through sensitivity analysis.
This paper conducts an exploratory case study-based research in three companies to identify the main synergies and misalignments between Lean and Green in the context of a range of distribution networks operating globally, regionally and domestically. The research strategy applied by this study is exploratory multiple case studies in three companies, particularly in the road transport and logistics sector. Semi-structured interviews with fifteen executives from three companies were conducted to identify activities within logistics operations leading to synergies and misalignment between Lean and Green practices. The outcome of the three cases shows that several improvements can be achieved by the simultaneous adoption of Lean and Green. The study contributes to the literature by extending the research in the logistics sector and providing examples from a wide variety of logistics operations on synergies and misalignments between Lean and Green practices. The findings and outcome of this study are a starting point for further research in the logistics sector.
We assess the antecedent link between lean and green practices and assess the combined impact of lean and green practices on both environmental and operational performance. A lean and green practices performance model is proposed that incorporates lean and green practices as antecedents to both environmental and operational performance. Structural equation modelling was used to analyse data collected from a sample of 182 manufacturing managers in U.S. plants. We found that lean manufacturing practices are positively associated with environmental performance and operational performance and that green supply chain management practices are positively associated with environmental performance and environmental performance is positively associated with operational performance. No support was found for the idea that green supply chain management practices are positively associated with operational performance. While lean practices were found to directly affect environmental performance, the indirect effect of lean practices on environmental performance through green practices is stronger, indicating complementarity.
Lean based systems include several practices and tools that have the potential to facilitate an organization to be economically, environmentally, and socially sustainable. The objective of this research is to integrate applications of lean systems in the design and planning model of a supply chain to improve sustainability performances of the overall business. The study defines and identifies antecedents, enablers, and ingredients of sustainable supply chain based on the literature. It also identifies practices and outcomes of Lean based systems that may be applied to supply chain functions in the perspectives of established sustainability criteria. Such practices and outcomes of lean based systems are then incorporated in the design of a sustainable supply chain to become enabler, antecedents or ingredients of sustainability to improve overall business performances. A numerical example illustrates the applicability of the approach.
A constant evolution in the efficiency of production systems and government policies has enabled the control of the environmental impact of production activities and encouraged companies to develop strategies to achieve more sustainable operations. Despite this, more needs to be done to reduce the risks of globalised production activities. In this context, evidence suggests that Lean Manufacturing (LM) and Cleaner Production (CP) make a positive contribution to the environmental performance of organisations. However, very little has been reported in the scholarly literature regarding the convergence and divergence of these two approaches. This work therefore attempts to take advantage of the synergies of LM and CP by proposing a Lean Cleaner Production Benchmarking (LCPB) method to assess the practices and culture regarding the application of CP in companies. The method considers the management aspects of people, information, products, suppliers and customers, management and processes, as well as the LM practices that contribute to a more eco-efficient production. LCPB uses a methodology based on benchmarking that was applied to 16 Brazilian manufacturing companies in order to assess their practices and performances regarding CP. The method seeks to provide a diagnosis to verify whether CP is effectively carried out by the companies, and what their performances are regarding actions beneficial to the environment. The application of LM practices that contribute to CP was also evaluated through the proposed LCPB method. The paper contributes to the theory by proving further evidence of the compatibility and synergies of LM and CP. In addition, it proposes a novel method that enables the analysis of companies' practices and performances related to CP, assesses their actions associated with sustainability, and contributes to identifying points where there is a lack and difficulty regarding CP. The proposed method helps to relate LM and CP activities, indicating that companies that seek to apply LM concepts are those that present high CP practices and performance.
