Abstract

Purpose

The paper aims to identify, prioritize and rank lean practices in the context of an Indian automotive component manufacturing organization using interpretive ranking process (IRP) and interpretive structural modeling (ISM) approaches.

Design/methodology/approach

Lean practices are identified from the literature. Then, two hierarchical models were are developed using two distinct modeling approaches – ISM and IRP with expert opinions from an Indian automotive component manufacturing organization to analyze the contextual relationships among the various lean practices and to prioritize and rank them with respect to performance dimensions.

Findings

In the study, the hierarchical structural models are developed using ISM and IRP approaches for an Indian automotive component manufacturing organization. In ISM-based modeling, lean practices can be categorized into five levels. Top priority should be given to the motivators followed by value chain, system/technology and organization centric practices. IRP model shows the dominance relationship among the various lean practices with respect to performance dimensions.

Practical implications

The models are constructed from the organizational standpoint to evaluate their impact to the implementation of lean manufacturing. The study leverages the organizations to prioritize limited resources as per the hierarchy. Managers get the inter-linkages and ranking of various lean practices, which leads to a better perspective for the effective implementation of lean. The structural models also assist management to assign proper roles to employees/departments for effective lean implementation.

Originality/value

There is hardly any structural model of lean practices in the literature for clustering, prioritizing and ranking of lean practices. The study fills this gap and develops the hierarchical models of lean practices through IRP and ISM approaches for an Indian automotive component manufacturing organization. The results from both approaches are compared for illustrating the benefits of one over the other.

Abstract

Purpose

The purpose of this paper is to compare environmental performance of two shackle insulator manufacturing enterprises in India by evaluating and quantifying the life cycle environmental impacts in these enterprises using ISO 14040 guidelines.

Design/methodology/approach

All relevant life cycle phases – raw material, manufacturing, transportation and disposal – are considered. Primary inventory data for the two enterprises are collected through observations of processes at the sites. Ecoinvent 3.0 database is used as secondary data source. Process flow models are developed using Umberto software. ReCiPe impact assessment methodology is adopted to calculate environmental impacts in terms of endpoint categories of ecosystem quality, human health and resource availability; and midpoint categories of climate change, fossil depletion, human toxicity, metal depletion, ozone depletion, terrestrial acidification and water depletion.

Findings

This study has found that manufacturing phase followed by raw material extraction and transportation phases are responsible for most of the environmental impacts. This study also found that raw materials used in glaze preparation (manganese and ferrite), electricity, heavy fuel oil (C-9) and cotton have high environmental impacts in the manufacturing phase.

Research limitations/implications

The limitation of this study is that most of the inventory data are collected from only two manufacturing plants.

Practical implications

The researchers/enterprises can use the knowledge body for modelling and result comparison under different conditions. The enterprises can do the micro analysis of environmental effects of processes to improve environmental as well as economic performance. The government agencies can use the data for policy development and deployment.

Originality/value

The main contribution of the research is the creation of a knowledge body in the area of ceramic product environmental impacts. The paper provides inventory for the life cycle assessment (LCA) of shackle insulators using primary source (measured values) as no secondary data source is available for the shackle insulators. The inventory and results of this study can be used as reference for the future LCA studies in ceramic industry.

This paper proposes an integrated value stream mapping (VSM) for a complex assembly line to improve the leanness of a complex automotive component manufacturing organization.

Abstract

Purpose

This paper proposes an integrated value stream mapping (VSM) for a complex assembly line to improve the leanness of a complex automotive component manufacturing organization.

Design/methodology/approach

This study depicts the application of VSM at the case organization, where top management is concerned about the challenges of higher cycle time and lower productivity. Gemba walks were conducted to establish the concept of “walk the flow, create the flow” along the assembly line. The multi-hierarchical cross-functional team developed the current value stream map to know the “as-is” state. Then, the team analysed the current VSM and proposed the future VSM for the “to-be” state.

Findings

The integrated VSM shows different processes and work cells, various wastes, non-value-added activities, cycle time, uptime and the material and information flows for both products of the assembly line on the same map. The integrated VSM reduced cycle time, non-value-added activities, work in process inventory and improved line efficiency and production per labour hour for both the products, simultaneously.

Research limitations/implications

The limitation of the study is that the study focussed only on the application of VSM for one complex assembly only. Future research may be conducted using the developed integrated VSM approach in other complex production environments.

Practical implications

Managers can identify and reduce system waste by incorporating the concept of integrated VSM in a complex production or assembly environment where two or more products are being manufactured/assembled with low similarity.

Originality/value

The application of VSM for assembly lines is highly challenging because of merging flows, a large number of child parts in the lines and assembly of more than one product on the same line.

Abstract

Purpose

There is a dichotomy in the actual and expected environmental performances of the Indian enterprises even though the Indian enterprises have aligned their businesses with intended nationally determined contributions (INDC) targets. The purpose of this paper is to analyze the supply chain of Indian enterprises to understand influences to adopt green practices throughout the supply chains, and how these green practices influence economic, operational and environmental performances to reveal the underlying currents explaining difference in actual and expected performance.

Design/methodology/approach

Five research propositions are developed based on the existing literature. Data are collected from 233 ceramic enterprises in India. Exploratory factor analysis has been done to test construct validity and correlation. Confirmatory factor analysis is used to check unidimensionality of constructs. Structural equation modeling is used to test the strength and direction of the relations between the constructs and to develop the model.

Findings

The findings of the study suggest that the Indian companies have aligned their businesses with INDC targets but they have not adopted the green practices in inbound and outbound supply chains; therefore, the actual environmental performance is not as expected. Other major finding is that the enterprise and government are not focusing on the informative pressure and instead the focus is on coercive techniques which are not yielding positive results. The statistical results show that the adoption of green practices led to the improvements in environmental and operational performances but reduction in economic performance.

Originality/value

This paper has analyzed green supply chain management pressure, practice and performance measure for Indian ceramic enterprises and proposed a structural model with their interrelation.

Abstract

Purpose

The purpose of this paper is twofold: first, to develop a statistically reliable and valid model of performance measures (PMs) to observe the environmental behavior of different enterprises; second, at benchmarking the enterprises based on their green practices.

Design/methodology/approach

A PM model has been proposed using an empirical analysis of manufacturing industry. The developed model has been tested using structural equation modeling technique. The level of green manufacturing (GM) performance in different sectors and sizes of Indian manufacturing industry has been studied and benchmarked using hierarchical cluster analysis with one-way ANOVA.

Findings

The results indicate that top management commitment and product design are the root PMs for the success of GM practices. It has been found that chemical, automotive, food and pharmaceutical industries are the high performing sectors. It has also been found that large scale enterprises are performing better than medium-sized enterprises which are doing better than small and micro enterprises in GM practices.

Research limitations/implications

The indicators/variables in questionnaire are subjective in nature and collected data are from Indian manufacturing organizations only.

Practical implications

The governments, trade bodies and NGOs can use the proposed model for measurement of green performance of any manufacturing industry. The benchmarking can be used by the different policy influencing and making agencies to develop future policies for the improvement. The industry can also use the benchmarking for its peer performance improvement.

Originality/value

The major novelty of the paper is benchmarking the green performance of manufacturing industries based on the different sectors and sizes using empirical investigation. The level of GM performance in different sectors and sizes of industries has been studied and benchmarked using hierarchical cluster analysis with one-way ANOVA.

Abstract

Purpose

The concept of green supply chain management (GSCM) is evolving rapidly due to the environmental concerns and gaining popularity in the research community. This study critically analyze the literature of GSCM pressure, practice and performance for manufacturing enterprises based on the results of bibliometric, network and frequency analyses.

Design/methodology/approach

Scopus database is used for literature search. Bibliometric network and frequency analysis are used to critically review the evolution of identified constructs and measures of GSCM pressure, practice and performance.

Findings

This study has identified that the selected topic is in growing stage through the collaborative effort of the worldwide researchers. This study also shows the diffusion of influence in developing countries and there are enormous opportunities of research in these regions. The study finds evaluation of GSCM constructs and measures with time and shift in focus areas by the researchers. The study suggests more focus on the measurement of informative pressures, reverse logistics practices and negative impact on economic performance due to the adoption of GSCM practices. There is a need of simultaneous analysis of GSCM pressures, practices and performance to identify the cascading effect in different regions and industrial sectors and developed a conceptual framework to identify this effect. This study also observes the need of more quantitative measures-based case studies and suggests the use of life cycle assessment for the quantification of environmental performance.

Originality/value

This study for the first time has analyzed a specific topic of GSCM pressure, practice and performance through bibliometric and network analyses. This study critically reviews the constructs and measures of GSCM pressure, practice and performance and identified the future research directions.

Abstract

Purpose

The purpose of this paper is to identify and analyze the impact of green supply chain management (GSCM) pressures, implementation level of GSCM practices and improvement in performance of the Indian ceramic enterprises. The paper also aims at benchmarking the Indian ceramic enterprises based on enterprise size and market orientation (export activity).

Design/methodology/approach

The research is based on the empirical study of Indian ceramic industry. Propositions are developed to study: the impact of GSCM pressures, implementation level of GSCM practices, improvement in GSCM performance, and the effect of GSCM pressures on implementation of practices, and impact of GSCM practices on GSCM performance. Data are collected from Indian ceramic enterprises of different sizes. Exploratory factor analysis is performed to segregate the pressures, practices and performance variables into constructs. Two-step algorithm, with log-likelihood measures of distance and Bayesian information criterion, is used to decide the optimal number of clusters. These clusters are compared and benchmarked according to the enterprise size and export activity.

Findings

This study finds that the implementation level of GSCM practices is higher in large- and medium-size enterprises as compared to small-size enterprises. Large- and medium-size enterprises have high impact of mimetic and informative pressures and small enterprises have high impact of coercive pressure (CP). Although the CP is high on small enterprises but due to the limited resources, these enterprises cannot afford to implement GSCM practices. The implementation of GSCM practices results into the improvement of environmental and operational performance but decrease in economic performance.

Practical implications

The findings of this study will suggest the policy maker to encourage the diffusion mechanism through a collaborative partnership with larger enterprises to enhance the implementation level of GSCM practices in small-size enterprises.

Originality/value

The novelty of the paper are: it analyzes and benchmarks GSCM pressures, practice and performance for Indian ceramic enterprises by considering enterprises size and export activities as control variables, and it finds the effect of GSCM pressures on the implementation level of GSCM practices and improvement in enterprise performance for Indian ceramic enterprises.

Abstract

Purpose

The purpose of this paper is to propose an integrated performance measurement framework to measure the effect of lean implementation throughout all functions of an organization.

Design/methodology/approach

The paper identifies the seven categories representing all organizational functions. These categories have been divided into 26 performance dimensions and key performance indicators (KPIs) for each performance dimension have been identified to measure lean performance. The interrelationship of each category with lean principles and/or lean wastes has been identified. KPIs are developed on the basis of identified criteria, frequency analysis of existing literature, and discussion with industry professionals. Finally, an integrated performance measurement framework is proposed.

Findings

The proposed framework evaluates the organization under seven categories – manufacturing process, new product development (NPD), human resource management, finance, administration, customer management, and supplier management. In total, 26 dimensions and 119 key performance indicators have been identified under the seven categories.

Research limitations/implications

The proposed framework is a conceptual framework and it is to be tested by empirical and cross-sectional studies.

Originality/value

The main novelty of the research is that the leanness of the organization has been measured throughout the supply chain of the organization in an integrated way. The various areas of measurement are manufacturing process, NPD, finance, administration, customer management, and supplier management. Further, the proposed KPIs are also categorized as qualitative or quantitative, strategic or operational, social or technical, financial or non-financial, leading or lagging, static or dynamic. This paper contributes to the body of knowledge in performance measurement.

Abstract

Purpose

The purpose of this paper is to develop a framework and key performance indicators (KPIs) to assess the sustainability of the manufacturing organizations along the integrated supply chain.

Design/methodology/approach

A systematic literature review of existing peer-reviewed articles has been carried out to understand the strengths and weaknesses of current frameworks. A sustainability assessment framework has been proposed for the manufacturing sector. KPIs to assess sustainability performance of manufacturing organizations are identified. An empirical study is carried out for the cement industry to test the proposed framework and KPIs.

Findings

The existing frameworks on sustainability assessment lacks an integrated assessment consisting product life cycle, resources, critical factors (product, process and policy), KPIs and their interrelationship with sustainability dimensions. In total, 121 KPIs are identified for sustainability assessment of manufacturing organizations. The empirical study of the Indian cement industry identifies 52 KPIs (17 social, 15 economic and 20 environmental), which are classified into 13 factors using exploratory factor analysis.

Research limitations/implications

The proposed framework is tested for the cement sector. More studies are required to validate and refine the framework to make it generalized for the manufacturing sector.

Originality/value

This study has developed for the first time a close interrelation among life cycle engineering, resources, critical factors, KPIs and sustainability dimensions.

Abstract

Purpose

The purpose of this paper is to aim at prioritizing and identifying the interrelations among the green supply chain management pressures, practices and performance measures. The study also compares the reasons of green supply chain management implementation, levels of implementation and improvement in performance for medium and large Indian ceramic enterprises because of green supply chain management implementation.

Design/methodology/approach

The most frequent constructs and measures of green supply chain management pressure, practice and performance are identified from the literature. The identified measures are corrected/added/removed, as per the suggestions of industry professionals, to develop a survey instrument. An interpretive structural model is developed to prioritize the constructs. Matriced “impacts croises-multiplication applique” and “classment” (MICMAC) analysis is done to identify the driving and dependence powers of the constructs. The identified results are validated through the descriptive analysis of responses obtained from multiple case studies.

Findings

It is observed that the informative pressures followed by coercive and mimetic pressures are the main drivers for the implementation of green supply chain management practices. Internal environmental management in enterprises is found to be the driving power behind the implementation of other green supply chain management practices. The implementation of these practices drives the environmental and operational performance. It is observed, through the multiple case study analysis that the impact of the pressures to adopt green supply chain management practices is high on Indian ceramic enterprises but the implementation of practices is in the early stage. The improvement in performance is also not found to be significant at this stage. This study also found that large ceramic enterprises are doing better than the medium enterprises in terms of green supply chain management implementation, largely because of higher pressures and availability of resources.

Originality/value

This study prioritizes the constructs of green supply chain management pressure, practice and performance for Indian ceramic enterprises and compares the large and medium enterprises on the basis of these constructs.
