Purpose: This research aims to propose a framework to integrate Green Lean Six Sigma (GLSS) and Industry 4.0 to improve organizational sustainability.Design/methodology/approach: The integration of GLSS and Industry 4.0 is proposed based on theoretical facets of the individual approaches. A generic, conceptual framework of an integrated GLSS-Industry 4.0 approach is then proposed using the application of different tools and techniques of GLSS and Industry 4.0 at different stages of the realization of a project.Findings: Both approaches have common facets related to enablers and barriers, and the integrated application of tools and techniques of each approach supplements the common focus of both related to sustainability enhancement. The proposed, conceptual framework provides systematic guidelines from the project selection stage to the sustainment of the solution, with the enumerated application of different techniques and tools at each step of the framework.Originality/value: This research is the first of its kind to propose the integration of GLSS and Industry 4.0 under the umbrella of a unified approach, including a conceptual framework of this integrated GLSS-Industry 4.0 approach.

The increased awareness about the effect of operations on sustainability dynamics and governmental pressure to cut emission rates has forced industries to adopt sustainable approaches such as Green Lean Six Sigma (GLSS). Despite increasing interest in GLSS, very limited research has focused on its implementation and no research has investigated barriers that hinder GLSS execution. This article investigates GLSS implementation barriers, their relationship, and removal of same in the manufacturing sector. In this article, 18 GLSS barriers have been recognized through literature review and formulated into logical groups using principal component analysis. This article pioneers with decision-making trial and evaluation laboratory with intuitionistic fuzzy (IF) set to prioritize barriers and handle the important and causal relationship among the same. The results of the article were validated through the IF best-worst method (BWM). The results reveal that management-related barriers are the top ranked followed by environmental and organization barriers with BWM weights 0.5283, 0.1704, and 0.1035, respectively. This provides impetus to policymakers for the induction of GLSS in business organizations to make harmony between economic development and environmental sustainability.

Purpose: The main aim of this study is to review different aspects of Industry 5.0 (I5.0) along with Kaizen measures to foster this novel aspect of industrial sustainability. The study makes a comprehensive study to explore the implementation status of I5.0 in industries, key technologies, adoption level in different nations and barriers to I5.0 adoption together with mitigation actions.Design/methodology/approach: To do a systematic study of the literature, the authors have used preferred reporting items for systematic reviews and meta-analysis (PRISMA) methodology to extract articles related to the field of the study.Findings: It has been found that academic literature on the I5.0 is continuously growing as the wheel of time is running. Most of the studies on I5.0 are conceptual-based, and manufacturing and medical industries are the flag bearer in the adoption of this novel aspect. Further, due to I5.0's infancy, many organizations face difficulty to adopt the same due to financial burden, resistive nature, a well-designed standard for cyber-physical systems (CPS) and an effective mechanism for human–robot collaboration. Further studies also provide avenues for future research in terms of the identification of collaborative mechanisms between machines and wells, the establishment of different standards for comparison and the development of I5.0-enabled models for different industrial domains.Originality/value: The study is the first of its kind that reviews different facets of I5.0in conjunction with Kaizen's measures and application areas and provides avenues for future research to improve an organization's environmental and social sustainability.

Purpose: The purpose of this study is to review the different facets associated with Industry 5.0 (I5.0) and propose a conceptual framework to boost the applicability of this novel technological cum social aspects within industrial organizations for improved organizational sustainability.Design/methodology/approach: This research work adopted a bibliometric analysis that encapsulates a quantitative set of tools for bibliometric and bibliographic information. This study uses the database of Scopus to acquire data related to different facets of I5.0. The study implies a different spectrum of terms to reach the final corpus of 91 articles related to I5.0. Furthermore, a conceptual define, measure, analyze, improve and control (DMAIC)-based framework based on different literature findings is proposed and validated based on the input of experts from different parts of the world.Findings: The results indicate that I5.0 is still in its infancy. The wider applicability of I5.0 demands comprehensive theoretical knowledge of different facets of this new paradigm and the development of a framework to adopt it on a larger scale. Organizations that are in the race to adopt I5.0 face major challenges related to the digitization of processes along with well-defined cyber-physical systems and the lack of a dedicated framework to execute I5.0. Furthermore, the result also suggests that manufacturing industries are more ready to adopt I5.0 practices as compared to service industries, which can be attributed to well-defined technological measures available in manufacturing settings.Originality/value: To the best of the authors’ knowledge, this is one of the first studies that explore different know-how and challenges and provides a holistic view of I5.0 by providing a systematic adoption framework.

Modern organisations are in quest of initiatives that will facilitate them to be sustainable as well as provide a competitive advantage to remain a continuous stakeholder in the global market. Green Lean Six Sigma (GLSS) is an inclusive approach that not only improves environmental sustainability but also leads to improvement in the financial stability of the organisations. To implement the GLSS strategy, it is essential to integrate Green, Lean, and Six Sigma initiatives under the umbrella of GLSS. In this study, GLSS integration has been proposed based on intangible features like enablers, toolsets, etc. Management dedication, participation, and team effort have been recognised as the most remarkable enablers to implement GLSS in the manufacturing sector. Moreover, this study also proposes a five facet GLSS framework for the manufacturing sector to enhance organisational sustainability. The current work will facilitate managers and practitioners to execute a sustainable GLSS programme in manufacturing firms for increased operational excellence as well as environmental sustainability.

Purpose: The purpose of this paper is to identify and prioritize prime just-in-time (JIT) elements in Indian healthcare sector based on the degree of importance and difficulty. This facilitates the implementation of JIT philosophy in healthcare services without any failure as well as provides quality services to patients at low cost.Design/methodology/approach: JIT elements related to health care services have been sorted out from comprehensive literature survey. Moreover, important and difficult JIT elements have been ranked on the basis of score obtained by the quantitative method using statistical tools. Furthermore, validation and prioritization of important JIT elements based on the degree of importance have been computed using the analytical hierarchy process (AHP) and best worst method (BWM).Findings: The present work provides important, difficult and easy to implement JIT elements in healthcare services. Besides, this work justifies the application of decision-making tool (AHP, BWM) for the prioritization of JIT elements in the health care sector.Practical implications: The present study develops a deep understanding of JIT concepts in health care services. Furthermore, it motivates professionals for implementing JIT in healthcare services with healthy situation for both hospital and supplier.Social implications: The present work is beneficial for all the dimensions of sustainable development (social, economic and environmental). The implementation of JIT with a proper understanding of its elements results in an improved patient care, lesser cost of healthcare delivery, time and better management of associated medical items. This work also facilitates the proper management of inventory items together with the reduction in various Lean wastes with the proper implementation of JIT in healthcare. The reduction in various associated wastes leads to cleaner surrounding and lesser environmental degradation.Originality/value: This paper outlines the need of a robust JIT approach in the healthcare sector for quality services. The efficacy of JIT, AHP and BWM has been explored to find out critical elements for successful JIT implementation in health care.
