The purpose of this paper is to develop and empirically validate an instrument containing operational measures of lean service. The instrument is intended for use by both researchers and practitioners.

The instrument was developed and validated in an iterative process between theoretical and empirical insights. Drawing on a wide selection of frequently cited papers on lean service, a preliminary list of items was generated. These items were then vetted through four steps in order to achieve high validity. Empirical refinement and validation included workshops and semi‐structured interviews with expert practitioners, as well as testing the instrument's ability to discriminate between high and low adoption of lean and portray changes during lean service adoption.

The instrument contains 34 items that assess enablers of lean adoption, lean practices, and operational performance. Empirical validation suggested the instrument was able to discriminate between high and low adoption of lean service, as well as portray changes over time during lean adoption.

Practicing managers will be able to use the instrument in order to track progress during lean service adoption, thereby identifying and acting upon deviations from planned progress.

The paper represents the first comprehensive attempt to develop an instrument for assessing lean service adoption. Through this instrument, operational definitions of lean service will allow researchers to measure the level of lean service adoption, and using this information, to develop knowledge of for instance the contingencies to lean service adoption, the problems and pitfalls in lean service adoption and the feasibility of transferring practices to various service settings.

The paper tests if and to what extent lean management system adoption generates abnormal profitability, and how it accrues over time. Configurational approaches to lean management systems and “S-curve” effects in lean implementation are used to ground the paper's hypotheses and interpret its findings.

Using the emerging view of lean as enterprise-wide management systems, this quasi-experimental study uses a difference-in-differences approach to estimate the abnormal profitability (ROIC) attributable to lean management system adoption. The paper leverages a unique data set of lean adopters nested in a panel data set (19 years) of 2,088 industrial firms matched by industry and firm size. It applies a variety of regression methods (two-way fixed effect panel estimator, propensity score matching, instrumental variable two-stage-least squares) to estimate the size of the abnormal profitability attributable to lean management systems, addressing endogeneity issues related to non-random sampling, omitted variable bias and reverse causation. It also analyzes the cross-firm variability of such abnormal profitability and how it accrues over time.

For the average non-adopter in the sample (44.3 million euro revenues), lean adoption generates abnormal ROIC ranging from 1.4% to 3.9%. These results come into effect approximately three years after starting lean adoption and peak after eight years. While the average abnormal profitability attributable to lean adoption is sizable, it varies significantly across firms and over time. This significant variation is compatible with firms' diverse ability to understand the complex inner workings of lean systems, and to design and implement them so that they improve profitability.

The conceptualization of lean as enterprise-wide management system can be further refined to more effectively categorize the components of lean systems and investigate the nature of their relationships. Lean system adoption measurement can be fine-tuned to better capture cross-firm and longitudinal heterogeneity. Future work can explore other dependent variables of interest to different stakeholders including shareholders' value, employment and environmental and social sustainability.

The financial benefits of adopting lean can be reaped to the extent to which managers embrace lean as a philosophy and implement it pervasively in the organization. A firm can use the study's estimates as a basis for making calculations about the returns of investment in lean adoption. The paper also shows that “getting the lean system right” makes a significant difference in terms of abnormal profitability, which is twice as large for the best lean adopters..

Compared with the promises of many lean proponents and supporters, the paper provides a more realistic view of what to expect from lean adoption in terms of profitability. Adopting lean as a comprehensive, enterprise-wide management system is not a universal panacea, but a complex endeavor, characterized by multiple complex decisions that require considerable capabilities, coordinated efforts and consistency of action.

Differently from extant research, this study does not study the correlation between the adoption of lean operation practices and financial performance but focuses on the abnormal profitability generated by the adoption of lean as a pervasive, enterprise-wide management system. Its research design allows to identify the differential profitability attributable to lean adoption and documents that it accrues non-linearly.

In times of strong global competition and worldwide economic downturn, there is an imperative need for public services organizations to reform and improve their quality. These organizations can base their improvement efforts on Lean philosophy. The purpose of this study is to assess the employees’ perceived degree of adoption of Lean principles by public services organizations in Greece. Determining the differences in the perceptions of groups of employees with regard to the adoption of Lean principles by public organizations is also an aim of the study.

A questionnaire survey was published online, inviting employees of Greek public services organizations to assess the degree of Lean adoption by their organizations, specified on the basis of general principles. A total of 1,022 employees completed the structured questionnaire. Descriptive statistics were applied to assess the degree of adoption of Lean principles by public organizations. The nonparametric Mann–Whitney U Test and Kruskal–Wallis Test were also applied to determine whether there are statistically significant differences in the perceptions of groups of employees with regard to the adoption of Lean principles by public organizations.

According to the perceptions of employees, Greek public organizations adopt Lean principles to a high extent. However, there is room for further improvement in the degree to which Lean is adopted. Statistically significant differences are observed in the perceptions of groups of employees from different sized organizations, hierarchical levels, skill sets and service subsectors, with regard to the degree of adoption of Lean principles by their organizations.

The employees of the public sector who were invited to respond to the survey through social media, the subjective nature of the data collected and the fact that this is a country-specific study constitute the main limitations of the present study, based on which future studies can be designed.

By determining the strong and weak points of the adoption of Lean principles by Greek public services organizations, suitable managerial initiatives can be undertaken by these organizations to fully adopt Lean, eliminate waste and enhance quality management.

Understanding and improving the current status of the adoption of Lean principles by Greek public organizations will influence the services provided to the citizens in terms of time, quality and delivery.

To the best of the authors’ knowledge, this is the first study which provides insights, based on employees’ perceptions, into the adoption of Lean by the public services sector.

The purpose of this paper is to identify and empirically validate a repertoire of management behaviors associated with the adoption of lean systems, showing how a subset of such behaviors differentiates more advanced lean systems in a specific setting.

The study applies regression analysis and non-parametric hypothesis testing to an original data set coming from field research of 26 cases of adoption of lean operations practices.

The study: identifies in the lean literature a repertoire of management behaviors that support lean implementations and complement the adoption of lean practices; provides a way to operationalize them; validates this repertoire of behaviors; and shows that a subset of these behaviors is associated with more advanced lean implementations, suggesting the necessity to adopt a situational approach to lean leadership.

The findings have boundary conditions, defined by the national, industrial, and size context in which the study was conducted.

The study provides practical guidance for lean system implementation suggesting a repertoire of management behaviors within which firms can identify and validate specific, appropriate subsets of behaviors aligned with the company strategy, culture, size, environment, bundle of lean operation practices adopted, and maturity stage of lean adoption.

This is the first study to provide quantitative, non-anecdotal evidence of the relationship between specific management behaviors and the successful implementation of lean operations practices. It offers a novel method to operationalize and measure lean management behaviors.

Previous research has managed to clearly define lean technical competencies. However, the behavioral competencies remain underestimated, and the roles of lean experts are not clearly stated: are they teachers, facilitators or technical experts? The present paper investigates lean behavioral competencies and their relationship to lean experts' roles.

This article serves as an exploratory study built on interviews, observations and focus groups conducted during a three-year longitudinal study accompanied by a three-year follow-up. The case takes place in an international automotive company in partnership with Toyota in which lean adoption was part of a consistent strategy over a period of 20 years.

The study clarifies lean behavioral competencies related to organizational efficiency (nominal management, improvement management and respect for people) and relational efficiency (problem resolution, competencies development and systemic interactions). The study helped create a typology of lean experts' roles related to the maturity level of the environment in which they intervened. Moreover, Lean experts' roles in congruence with the environment seem to positively influence the creation of emerging human relationships that are beneficial to process improvement and competencies development.

This paper is the first to clarify behavioral competencies with respect to lean experts' roles and to study the temporality of the introduction of lean practices. The findings recommend that researchers better acknowledge the influence of lean behavioral competencies during lean adoption and their relationship to contextual factors and organizational performance. A practical methodology is proposed to measure the necessary behavioral adjustments of lean experts or employees.

The purpose of this paper is to identify forces (in the form of converters and inhibitors) of Lean Six Sigma adoption by studying the gradual adoption of Lean Six Sigma in a medium-sized Swedish manufacturing company. The paper suggests how the converters and inhibitors interact toward increased maturity of the adoption and, in this case, stagnation thereof.

Thirteen interviews were recorded and analyzed to identify converters that were moving the process forward or backward, as well as inhibitors that caused it to linger.

It was discovered that activities that had initially moved the process forward were not sufficient to move it beyond its current point. However, an increased knowledge of Lean Six Sigma throughout the organization now prevents the process from moving in the opposite direction. In this medium-sized Swedish manufacturing company, Lean Six Sigma becomes a framework for thought and communication during Lean work.

The study benefited from considering forces pushing the process forward as well as backward. Thus, the authors suggest that future studies will benefit from focusing beyond critical success factors that may at times are static in nature. As a limitation, for discussions about the past, the memories of interviewees, generally, may have a tendency to be biased.

The paper contributes knowledge of Lean Six Sigma adoptions and how they may attain greater future success by reporting on difficulties and setbacks in the current gradual adoption process in a chosen company.

The purpose of this paper is to identify the factors that promote the successful adoption of lean practices in manufacturing firms operating in developing economies in South America.

Based on the results obtained from using structural equation modeling to analyze the collected data, the authors argue that manufacturing organizations need to identify the factors that assist in successfully adopting lean practices in manufacturing firms operating in developing economies in South America. A dataset of 1,809 responses, gathered from manufacturing firms as part of the World Management Survey, was used to find support for the proposed hypotheses.

Several hypotheses were tested finding that lean practice success factors such as organizational targets proved to have a significant and positive relationship with the mediating factor, performance management. Likewise, performance management was also found to have a significant and positive relationship with lean practices adoption. Human capital management (HCM) has a significant but negative predictive relationship with lean practices.

The empirical results of this study provide valuable managerial insights. The results are therefore limited to the economies analyzed and to the variables surveyed as part of the World Manufacturing Survey research.

The results of this research provide a starting point for researchers to continue studying the key lean practice factors and relationships in the achievement of improved performance management, thereby helping managers in developing strategies to improve the lean capabilities of their practices. This, in turn, will increase the organization's competitive advantage sustainably.

This paper identifies and tests the impact of key factors on successful lean practices adoption in South American organizations in the manufacturing sector.

The purpose of this study is to determine the relationships between Lean adoption and organizational performance in a specific Greek public services subsector, namely, citizen’s service centers (CSCs).

An online structured questionnaire survey was distributed to all the Greek CSCs, and 672 employees responded and fully completed the questionnaire. Exploratory and confirmatory factor analyses were applied to assess the measurement model’s reliability and validity. The relationships between the latent constructs were examined through structural equation modeling.

The study revealed that Greek CSCs adopt at a medium to high extent the following principles: understanding customer needs, establishment of value streams, creating flows within the value streams and value perfection. The data also revealed a valid latent factor reflecting the Lean application, namely, “Lean adoption,” which, according to the findings, contributes to the organizational performance of Greek CSCs.

The small percentage of the responding employees of the Greek CSCs, given their large population and the subjective nature of the data collected, constitute the main limitations of the present study.

The findings of this research will serve as a reference source for managers and decision-makers of CSCs in order for them to set the foundations for successfully adopting the Lean principles and therefore improve their organizational performance in terms of operational performance and satisfaction with employees and citizens.

Building on the public sector literature, to the best of the authors’ knowledge, this is the first study that evaluates the adoption of Lean principles in the Greek CSCs and defines the relationships between Lean adoption and organizational performance.

Despite many Maintenance Repair and Overhaul (MRO) organisations alluding their positive business performances to the adoption Lean initiatives, there is a paucity of direct literature that validates this assertion. Thus, the purpose of this paper is to study empirically via the use of an industry-wide survey to establish and extent of Lean adoption and to verify its suitability in mitigating prevalent MRO challenges.

The empirical study contained in this paper is facilitated by an industry-wide survey to collect data from several firms across the MRO spectrum. The analysed responses from industry leaders, professionals and executives synthesised with existing literature was used in ascertaining the extent of Lean adoption within the operational framework of the industry.

The empirical study helped in validating the suitability of Lean in MRO context. However, it was also observed that the focus of its application was skewed towards its production-orientated functions more than its service-orientated functions. Nonetheless, this paper presents results of the positive influence of Lean in MRO context.

This empirical study presented in this paper was carried out within a framework of key characteristics of operation. Although this approach is sufficient in assessing the industry’s Lean status, further assessment can also be achieved within the context of relevant performance metrics which was not included in this paper.

By exploring the industry’s Lean status within the context of operational characteristics of operation, this study provides MRO practitioners with more awareness into some of the critical factors required for successful holistic Lean realisation.

The state-of-the-art of Lean within the aviation MRO context established through this research also contributes to the wider product-centric service environment by providing a platform that facilitates strategy development which ensures Lean success within this environment.

Apart from validating the suitability of Lean in MRO contexts, by establishing the extent of Lean adoption within the context of the operational framework, this paper provides a clearer insight as to how successful Lean implementation can be achieved via a holistic implementation strategy balanced between the product-centric and service-centric aspects of the industry.

This study aims to investigate the interrelationships between lean production, green technology adoption, green product innovation, social sustainability performance and green competitiveness. The study further investigates the mediation roles of green technology adoption and green product innovation between lean production systems, social sustainability performance and green competitiveness.

The quantitative research approach is used for the study. Data for the study is garnered from 197 managers of manufacturing firms in Ghana via a self-administered questionnaire. Structural equation modeling, specifically partial least square is applied as the methodological tool to test all hypotheses.

Results of the study suggest that lean production systems have a significant positive impact on green technology adoption, green product innovation and green competitiveness. However, lean production systems are found to have an insignificant impact on social performance. The results further confirm the mediation roles of both green technology adoption and green product innovation between lean production systems, social sustainability performance and green competitiveness; thus indicating that lean production systems create an efficient condition for firms to adopt green technologies and produce innovative green-based products to leverage superior social sustainability performance and green competitiveness.

This study proposes and develops a comprehensive research model that is supported by the natural resource-based view theory to investigate the link between lean production systems, green technology adoption, green product innovation, social sustainability performance and green competitiveness from an emergent country perspective.
