The practice of lean management (LM) principles has given firms, from a variety of sectors, quantum jumps in productivity and performance. India is at the cusp of a major leap in economic growth, and adoption of LM is a must for ramping up the rate of growth of the GDP speedily, if the government is really intent on achieving its objective of becoming the third or fourth largest economy soon. This paper aims to study the status of implementation of LM in the LM Leaders (LML’s) in the Indian industry, to understand if they are ready to accept the challenges ahead.

This is an exploratory research study. To study the level of maturity of LM in Indian industry, the authors selected the LM Leaders in the Indian industry (LMLII). By using a well-known survey instrument – the Lean Self -Assessment Tool (LESAT), Version 2.0 – designed and developed by MIT, the authors conducted a longitudinal survey over the period 2013 to 2016, a four-year duration. Surveys were conducted every year.

Survey results show an improvement in the overall average of “current state” scores between the years 2013 and 2016, indicating that LMLII’s have improved upon their LM adoption during these years. However, there is a striking gap between “where the industry wants to be” and “where it currently is”. This could drive future improvements. Based on the survey results, this paper draws lessons and proposes action points on how to improve the adoption and diffusion of LM principles and practices in the LMLII. Factors which need to be addressed to reinvigorate the practice of LM have been identified and classified as urgent, immediate and short term.

While many “snapshot” studies have been done to study LM in Indian industry, a longitudinal study has not been done. Moreover, previous studies administer questionnaires to one company (case study method) or a group of companies in a sector of the industry. Thus, there was a research gap. A longitudinal study will help us take a holistic approach. In addition, studying LMLII will provide data from the most serious adopters of LM. Both these will add value to the current research on LM in Indian industry. The results will also help the LMLII’s to further improve the practice of LM in a systematic and rigorous way. However, as the study is limited to the LMLII, it would not be possible to apply the knowledge to the Indian industry as a whole. For doing so, one would need a larger, more representative sample.

Using this paper, LMLII’s can develop practices which will improve customer satisfaction and reduce waste in manufacturing. They can ramp up LM intensity to make further quantum jumps in performance.

LM, in addition to improving the output/input ratio (producing more for less), also emphasises waste reduction, customer satisfaction and efficient operations. All these three factors are essential for sustainable and happy society.

The work is original. This is the first longitudinal survey of lean practices in the Indian industry to study cross-sectional practices, and the results will propel the Indian industry to intensify the practice of LM.

Lean manufacturing (LM) has advocated gains by reducing waste and intensifying continuous improvement. As a holistic organizational policy, it must overpass the limits of the manufacturing function. Management accounting should be aligned to lean thinking, aiming to meet the demands and goals of a lean organization. This paper aims to investigate the degree of alignment between management accounting systems and LM practices.

Two representative case studies were carried out in industry leaders in the implementation of LM, in Brazil. The key research constructs and were identified by means of a systematic literature review. The rhetoric and practice concerning the alignment between management accounting and LM are discussed based on the existing theory and the conducted case studies.

The analysis showed that many of the principles that form the rhetoric of lean accounting are far from the accounting practices observed in the companies. Using the theory-building function of case studies, 10 propositions to be tested in future research are proposed. The main propositions are also summarized in a framework based on analogies with optical lenses.

To the best of the knowledge, there are no previous in-depth studies focusing on characterizing this alignment between management accounting and LM practices. The analysis yields prescriptive directions for managers that seek to improve this alignment in their business. This study also proposes a five-stage maturity model, which can be used by the managers to assess this alignment and to set goals for reaching more advanced levels of maturity.

The purpose of this paper is to investigate the contribution to improving the efficiency of the focal firm made by lean management at the internal and supply chain levels.

An empirical study was conducted of 285 Spanish focal companies from industrial sectors that occupy an intermediate position in the supply chain. The data gathering method consisted of a telephone survey using computer-assisted telephone interviewing. A structural equation was used to test the hypotheses.

The results indicate that there is an improvement in efficiency of the focal firm when lean management extends throughout the supply chain, in line with the resource-based theory and integrated supply chain management. In addition, lean management at the internal level is observed to impact positively on the focal firm's efficiency only when it contributes to enhancing the implementation of lean supply chain management.

To achieve the best operational performance derived from lean management, managers should pay attention to the transfer to their supply chain members of knowledge, competencies and cultural change linked to the level of internal lean implementation of the focal firm. Moreover, this paper provides a way to assess the operational aspects of lean supply chain strategy implementation and lean supply chain planning.

This study uses a holistic focus on lean supply chain management, to which it applies a validated instrument. It underlines that lean on the internal level should be complemented with lean on the supply chain level to provide a better understanding of the drivers of the efficiency of the focal firm.

This study draws on the systems perspective to study the individual and combined interaction effect of lean management (LM) and sustainability management (SM) on the organization's triple bottom line (TBL) performance.

The study employs structural equation modeling to test the proposed hypotheses using data from the sixth version of the International Manufacturing Strategy Survey (IMSS VI).

The study finds that LM is positively related to all dimensions of the TBL performance. In contrast, SM is positively related to social and environmental performance and negatively related to economic performance. Finally, by finding that the interaction between LM and (SM) is positive for social and environmental performance, this study not only confirms that LM is an enabler for sustainability, but it also supports that the two paradigms are mutually compatible and reinforcing.

The findings imply that practitioners pursuing both LM and SM should leverage their mutual positive effects and balance the unintended effects of implementing isolated bundles by implementing them together as a complete socio-technical system. Their combined impact on the TBL performance will outweigh the sum of their individual effects in the case of isolated implementations.

In contrast with the extant literature, this study proposes that LM and SM make parts of one system as opposed to one correlated with the other or having a positive causal effect on the other. Taking an integrated systems approach, the study empirically verifies the “mutual compatibility” of the lean and sustainability paradigms argument, with regard to their effect on the TBL performance.

The purpose of this paper is to review original research on lean management (LM) in health care to identify potential research gaps and present recommendations for future research. The paper also discusses the current state of implementing LM practices in health care. In addition, it presents and highlights “lean bundles” imported from manufacturing, namely, total quality management (TQM), human resource management, just-in-time and total productive maintenance, as a potential implementation strategy of LM in hospitals to optimize overall health care performance.

The scoping review was conducted based on the guidelines specified by Arksey and O’Malley (2005). Relevant included studies were retrieved by searching various electronic databases. The PRISMA guidelines were applied to identify and select eligible studies.

The majority of previous studies used selected practices to measure LM in health care. In most cases, these practices reflected a narrow and biased view of LM. Lean bundles which comprehensively view LM and reflect all its aspects have rarely been discussed in the health care literature. Evidence about the contribution of lean bundles to hospital performance needs to be addressed in future studies.

This paper demonstrates the implementation of the four lean bundles in hospitals. It argues that, instead of adopting one dimension or selected practices of LM, hospitals viewing LM as a comprehensive multi-dimensional approach through the adoption of the four lean bundles are expected to maximize their performances.

This is one of the first works to comprehensively review and discuss lean bundles in the context of health care. It argues that the adoption of the four lean bundles by hospitals will enable them to yield the maximum LM performance benefits. In addition, a proposed survey questionnaire based on the literature review is provided to assist researchers in conducting future empirical studies.

This paper empirically examines the implementation pattern of different types of lean management (LM) techniques on the shop-floor. Based on the socio-technical systems framework, LM techniques are classified as social improvement tools and technical process standardization and stability practices. This categorization facilitates investigating their implementation relationship in a complex production system.

Based on the survey data from managers of the three major US auto-manufacturers and their suppliers (n = 137), measurement scales are developed using confirmatory factor analysis for the LM process improvement, stability, and standardization constructs. Hypotheses are tested by applying the Sobel test technique for mediating regression.

Statistical results confirm the mediation role of LM improvement tools between standardization and stability goal practices, indicating that technical process-oriented practices are not directly related and that their association is impacted by the corresponding implementation of social tools on the shop-floor.

The results indicate that LM practices should not be randomly implemented on the shop-floor but rather adopted and executed based on a systematic pattern. In LM systems, the implementation of process stability, standardization, and improvement practices on the shop-floor are more tightly integrated than traditionally assumed.

This study establishes a new categorization of specific LM tools based on social and technical characteristics. The conclusions highlight the importance of adopting a social emphasize of continuous improvement to establish a technical focus of process standardization and stability for LM implementation success.

The current research aims to map and investigate how human resource management and lean practices can be integrated. This investigation will help identify the HRM aspects critical in the success of lean initiatives while exploring the research gaps in the existing literature. The review also aims to delineate the benefits and challenges of integrating lean with HRM systems to discuss further research and practice areas.

This study utilizes a systematic literature review method to identify and synthesize the existing literature. As part of the process, a protocol that provided a plan for the review was followed, including the research questions and the data to be extracted.

The study results indicate that aspects of HRM practice and policies such as training and development, teamwork, motivation, communication, leadership, are key enablers of lean initiative deployment and success. The benefits of the integration of human resources with lean can help in lean training and development, communication of lean initiatives and successes, allocating and hiring continuous improvement personnel, and supporting leadership in lean deployment. Challenges to integrating lean and HRM practices included lack of integration and collaboration between disciplines. Further exploration areas in successful lean deployment would be practical longitudinal case studies on lean deployments with human resource (HR) partnerships and involvement.

This review paper has crucial implications for practice relating to, integration of lean with HRM structures and tailoring HRM initiatives to ensure the success of lean deployment and reduce risks of failure.

The systematic literature review study conducted in this paper is the first of its kind to integrate and map the HRM concepts that can be integrated with Lean to deploy the initiative successfully. This mapping is critical for ensuring the success of lean methodologies within an organization and paves the way for future research. In addition, managers and organizations can find support and guidance from this study to focus on vital areas of partnership between their lean and HR programs.

This paper aims to develop the existing theoretical concept of a triad by informing it with the activity-resource-actor (ARA) model in a new empirical context of lean management (LM).

This conceptual paper draws on the industrial marketing and purchasing (IMP) school of thought and the ARA model as theoretical lenses to inform research on triads in an LM context.

The authors find that closed buyer-supplier-supplier (BSS) and buyer-supplier-logistics service provider (BSL) triads, which we call “lean triads,” had a positive impact on LM. The authors display the drivers for closure – LM improvements (Table 2) and the properties of these “lean triads” (Figure 3).

The paper focuses only on closed triads and is based on previous empirical studies.

The authors demonstrate to lean managers the drivers for connecting their partners in BSS and BSL triads and show the importance of developing relationships on three layers between all three actors in both triads to improve a firm’s lean performance.

The authors contribute to the discussion within the IMP school of thought on the value of triads by enriching the understanding of a triad concept with the ARA model, which compounds a concept of a multilayered triad in an LM context.

The purpose of this paper is to identify the mediating effect of lean management (LM) dimensions on the relationship between flexible manufacturing systems (FMS) dimensions and operational performance metrics.

A survey questionnaire was developed based on previous literature and interviews conducted at the automotive facilities visited that identified 28 lean dimensions, 15 flexibility dimensions and 8 operational performance metrics. The survey was presented to 175 North American automotive manufacturing managers through interviews conducted at 64 automotive facilities. A total of 164 usable responses were studied.

Lean and FMS are multi-dimensional philosophies, the results demonstrate that the automotive industry in North America has implemented many dimensions of both philosophies. Each dimension is categorized based on specific organizational metrics. The 64 facilities studied use common dimensions identified by this study for lean and flexibility. Data analysis indicates a direct link between lean, flexibility and operational metrics. It shows that LM plays a critical role in improving the impact of flexibility on performance metrics. The results also indicate that specific lean and FMS dimensions or categories have higher significant roles than others in the relationship between LM, FMS and operational performance metrics.

Since the sample size only considered automotive manufacturing facilities, the results need to be considered with caution.

This research empirically develops a framework linking FMS and LM to operational performance metrics. This research addresses an area within which there is little consensus on the relationship between LM, FMS and their impact on operational performance metrics. The study is unique due to the depth and breadth of the investigation that far exceeds previous literature conducted. In addition, this research highlights the LM and FMS practices on which managers should focus on when attempting to improve operational performance metrics at their facility.

To identify the factors that need to be addressed by Indian industry to steeply ramp up its production and productivity in the coming years, so as to achieve the goal of the country becoming a 5 trillion dollar economy by 2025.

Lean Management Leaders in Indian Industry (LMLII), i.e. those companies in India who are well known for having adopted TQM, BE and Lean methods for many years, and achieved success in their business) in Indian industry were selected and surveys were done between 2013 and 2017, to assess the status of LM adoption, by using the LESAT (version 2.0) survey tool. A longitudinal empirical study has been done, over a period of five years, so that the identification of factors is based on a few years’ data rather than a one year, spot-check or snapshot view. A new method, titled the ‘Three Step Reverse Exploratory Factor Analysis Procedure (TSREP)’, has been attempted to identify the ‘root causes’.

LMLII's have improved in their adoption of LM over these years by about 10%. The root causes that can help in further advancement in adoption have been identified and classified under six component factors.

The identification of LMLII's has been done based on the experience and views of experts in TQM/ BE/ Lean in India. Since this is a first of such study (viz., the term LMLII is being defined and used for the first time), this methodology has been adopted. However, in future, a systematic way to assess the criteria for LMLII's could be designed. Secondly, the sample size of LMLII's needs to be fully representative of the industry.

By using the results of this study, Indian companies can accelerate their LM adoption programmes, leading to quantum jumps in production and productivity, so as to achieve the 5 trillion USD economy by 2025. The practical implications are immense.

Since LM is a bundle of Lean, TQM and BE, companies adopting LM will, due to the inclusion of waste reduction through 5S, JIT, kaizens and continuous improvement, address the Triple Bottom Line (TBL) protocol of the UN. TBL has comprehensive implications on society and environment, climate change and sustainability of business.

This work is original, at least in three ways. First, in the use of the concept of ‘LML’. Second, there is no previous longitudinal study done on Indian industry in LM. Third, the TSREP is being used for the first time. The value of this research is in its findings, in the identification of key factors for future growth and the use of a novel technique for improving upon the accuracy, analytical rigour and legitimacy of the results.
