Although leadership in lean systems is influenced by context, the mechanisms linking contextual factors (CFs) to leadership have not been explored. This study aims to present a framework for analyzing how context influences lean leadership competencies (LLCs).

The framework’s design was based on insights from literature and refined through an empirical study of a large manufacturing plant formally committed to lean. The evolution of CFs over time was monitored in this study, allowing for analyzing how these triggered the need for using LLCs.

The framework proved to be useful for as follows: the assessment of LLCs in different hierarchical levels; the analysis of how CFs and LLCs interact in specific “leadership events”; and the identification of improvement opportunities for supporting leadership. Four design propositions emerged from the empirical study, offering complimentary guidance for using the framework.

The framework was tested in one company, and therefore generalizations about its effectiveness need further applications.

The framework may be used fully or partly by practitioners. For instance, the assessment of LLCs can be used as a standalone tool according to the specific needs of practitioners. Also, by producing rich descriptions of LLCs and CFs, the framework may inform lean leadership development programs.

The framework allows for a systematic analysis of how a broad range of CFs influence LLCs, thus operationalizing an idea that so far has been discussed mostly on a theoretical level.

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.

Service businesses are struggling with customer demands for better quality service and managerial demands for cost reduction. There is evidence to suggest that service businesses are in practice failing on both these counts, seeing increased costs and reductions in service quality. The application of lean production approaches to the service context has been suggested as a means to resolve these problems, reducing costs and improving quality. Despite the validation of lean approaches in the product‐service context, the application of lean approaches in the pure service environment remains largely untested. The purpose of this paper is to assess the suitability of lean production methodologies in the pure service context.

Three financial service companies in the UK were followed through a common programme of lean transformation. The improvements observed in each company were recorded. The change programme is evaluated to determine the “leanness” of the initiatives. The suitability of lean for the service context is discussed.

The paper's findings highlight significant improvements in quality and cost positions with minimal investment through adoption of lean tools in the pure service context. The paper proposes the suitability of basic lean methodologies such as value understanding, process mapping and problem solving for the pure service context.

The lean approach is well established in the manufacturing sector and certain product‐service contexts. Evidence on lean in pure service environments is very limited. The paper addresses this shortcoming.

This paper presents a proposal of adaptation of the failure mode and effect analysis method to analyze wastes and define priorities for actions aimed at minimizing or eliminating these wastes based on the criteria of severity, occurrence and detection.

The proposition was developed in parallel to the implementation of a lean production system of a manufacturing company. A pilot application of the proposal was based on the analysis of a flow of information for order processing.

Application of the proposed procedure results in a classification of levels of priority for waste reduction of the analyzed waste modes. Following this procedure, high priority will be given to actions focused on the elimination or minimization of the most common causes of the most severe waste modes.

Prioritization of actions to minimize waste is essential to sustain lean production systems. However, identifying the wastes most in need of attention is not always straightforward and methods presented in the literature to evaluate leanness do not focus on waste reduction prioritization. Adoption of the proposed technique can certainly aid planning implementation and improvement of lean production programs, and in the end, it can contribute to the effectiveness and sustainability of lean production systems.

The extant literature on lean service reveals a noticeable lack of theoretical models establishing the core constructs of lean service, their interrelation and impact on organizational performance. The purpose of this paper is to address this gap by proposing a theoretical model in which lean constructs are identified and operationalized to establish their interrelation and impact on organizational performance.

This paper synthesizes information drawing on a systematic review of the literature on lean service, other relevant academic literature to develop a theoretical model and a set of propositions. Drawing on the universal theory, socio-technical systems theory and contingency theory (CT), the paper highlights and clarifies the potential impact of lean service on operational and financial performance.

This study identifies a comprehensive set of lean technical practices, lean supportive practices, inhibitors and expected outcome of lean service. Expected relationships among those constructs are established by developing a conceptual framework with several propositions based on the relevant literature and the socio-technical system theory, the universal perspective and the CT, when relevant. Moreover, six influential contextual variables on the lean-performance relation are identified based on a review of the management accounting literature, organizational strategy literature and diversification literature to overcome limitations of previous studies.

This paper covers a gap in the literature by identifying and operationalizing lean service constructs and offering a theoretical model with several propositions that establish relationships between lean constructs and overcome limitations in previous studies by identifying six contextual variables that are important factors in the lean-performance associations.

Requirements for business improvement professionals depend on different job characteristics. By focussing on lean management, the purpose of this paper is twofold: first, to provide a comprehensive conceptualisation of competencies relevant for lean professionals by comparing them to an existing project management competency framework; and second, to identify their similarities and differences in three different analysed countries.

This paper investigates 2,701 online published job advertisements in the USA, UK and Germany by means of a content analysis to compare and contrast the respective job profiles.

Main findings are similarities and differences in the specification and perception of lean professional’s roles among the three countries. Strikingly, four out of eight considered competency categories comprise 74 per cent of the profiles’ most relevant keywords. Additionally, with the help of a latent semantic analysis, 16 specific competencies can be summarised in a lean professional’s competency taxonomy.

The collected data only represent a snapshot of lean professionals’ advertisements. Also, text mining results from job profiles could largely differ from other techniques like recruiter interviews or company surveys. Further research could use different methods or combine them to construct a more complete model.

Lean education and training as well as the respective candidate selection processes can benefit from these studies’ results.

Requirements and job contents for lean professionals have not been empirically researched on a comparable in-depth level before, even though their expertise is in high demand in any kind of business sector.

The present research aims to understand how the literature on lean leadership is currently structured. For this, the thematic subdivisions within the subject (thematic clusters) are analyzed as well as the networks between authors and the authors' countries and the chronological co-occurrence of terms over the years.

The research strategy chosen was a bibliometric analysis conducted with documents collected from the Scopus scientific database. After screening, 192 documents were analyzed using the Vosviewer software.

The main result is related to identifying four thematic clusters. The first cluster is connected to the manufacturing and supply chain industry, and this showed an increasing concern with sustainability, agile manufacturing and digitalization. The second is related to small and medium-sized companies in which Lean concepts, often associated with Six Sigma ideas, present as differentials for competitive advantage. The third one is associated with the civil construction segment, in which there is a great need for cultural and organizational change. The fourth cluster focuses on health organizations. In all clusters, leadership plays a key role.

Besides the contributions to the literature on the theme, this study provides interesting insights for managers regarding the path the managers' sectors are taking in the Lean leadership context.

There are no studies that critically examine Lean leadership literature. This research identifies clusters on the theme, showing how Lean leadership is being addressed by international research.

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.

The purpose of this study is to document the experience and impact of implementing lean thinking (LT) in an Indian healthcare institution.

A detailed review of literature documenting the experience of implementing LT in healthcare institutions is carried out. Review revealed that there is a dearth of documentation on implementation of LT in Indian healthcare institutions. To address this gap, the experience of implementing LT in an Indian case hospital is documented by adopting a single case study research methodology.

Lean practices adopted by the Indian case hospital are documented. Performance measures before and after implementation of lean practices in the case hospital are compared. Based on this experience, a framework for implementing LT is proposed for healthcare institutions.

The current study documents the experience of an Indian case hospital, which is only at its initial stages of LT implementation. Future studies can be undertaken to assess the long-term impact of implementing LT in a healthcare institution. Similarly, the proposed framework for implementing LT can be validated by using the same in different healthcare institutions.

Review of lean principles, practices and performance measures discussed in the literature on implementing LT in healthcare institutions can act as a ready reckoner for practitioners. Framework proposed based on the experience of the case hospital is expected to guide healthcare practitioners in their lean journey.

This study is unique, as it documents the experience of implementing LT in an Indian healthcare institution and proposes a framework for implementing LT for future validation.
