The purpose of this paper is to investigate how just-in-time (JIT)-related job demands, problem-solving job demands and soft lean practices (SLPs) jointly influence employee well-being in terms of work engagement and exhaustion.

Based on the job demands-resources model, lean-related job characteristics were classified as resources or demands, and a set of hypotheses was developed to test their effect on work engagement and exhaustion, including the potential interaction between job resources and demands. The hypotheses were tested using moderated hierarchical regression and structural equation modelling, based on data from 138 workers.

SLPs act as job resources in a lean company, increasing work engagement and reducing exhaustion. Conversely, JIT-related job demands act as a hindrance, reducing work engagement and increasing exhaustion. However, SLPs can reduce the effect of JIT-related job demands on exhaustion, and JIT-related job demands may enhance the positive effects of SLPs on work engagement.

The study provides no conclusive evidence on the hypothesized role of problem-solving as a challenge job demand.

The results can guide practitioners’ understanding of how to implement lean without harm to employee well-being.

By employing a well-grounded psychological model to test the link between lean and well-being, the study finds quantitative support for: the buffering effect of SLPs on exhaustion caused by JIT-related job demands, and for the role of JIT as a hindrance. These novel findings have no precedent in previous survey-based research. In addition, it reveals the importance of studying SLPs at an individual level, as what matters is the extent to which workers perceive SLPs as useful and supportive.

Lean remains popular in a wide range of private and public sectors and continues to attract a significant amount of research. However, most of this research is not grounded in theory. This paper presents and discusses different expert viewpoints on the role of theory in lean research and practice and provides guidelines for future research.

Seven experienced lean authors independently provide their views to the question “is Lean a theory?” before Rachna Shah summarizes the viewpoints and provides a holistic outlook for lean research.

Authors agree, disagree and sometimes agree to disagree. However, a close look reveals agreement on several key points. The paper concludes that Lean is not a theory but has plenty of theoretical underpinnings. Many lean-related theories provide promising opportunities for future research.

As researchers, we are asked to justify our research drawing on “theory,” but what does that mean for a practice-driven phenomenon such as lean? This paper provides answers and directions for future research.

The purpose of this paper is to deal with the transfer of lean practices between different units in multi-plant organizations with different levels of adoption of lean practices. It investigates how certain influential contextual variables – i.e. lean standards development, lean transfer team composition, source characteristics, recipient national environment and corporate lean programme deployment – can influence stickiness in the different phases of lean transfer process.

This paper opted for the multiple-case study method and examines six lean transfer projects at a dyadic level, that is, between a source and a recipient unit. The authors focussed on companies with headquarters in Europe with an attested experience in lean and which had recently and successfully transferred lean to subsidiaries in the USA and China.

The paper provides empirical insights about how stickiness in lean transfer projects changes during the initiation, implementation/ramp-up and integration phases. It identifies three lean transfer approaches (local, global, global and shared) and provides a set of propositions that explains how sociocultural traits of recipient environment (China vs USA) and lean transfer approach affect stickiness in each phase.

Literature on stickiness in lean transfer is at an early stage and very fragmented. Unlike previous contributions in the field, this paper provides an interpretation of the dynamics of stickiness in lean transfer at a micro-level (i.e. for each single phase of the lean transfer process). In addition, it develops a fuller understanding of the influence of context on lean transfer by adopting a configurational view, i.e. studying the joint effect of contextual variables on stickiness, which is a novelty in the lean transfer literature.

The purpose of this paper is to analyse whether the adoption of e-commerce improves company business, innovation and operational performance and whether sales internationalisation might moderate this relationship.

The research is based on a survey within the fashion industry and a multi-step linear regression model investigating the relationships between e-commerce and performance.

Results reveal that e-commerce improves innovation performance but has no significant relationship with business and operational performance. Also investigating whether the sales internationalisation might moderate the relationship between e-commerce and performance, the findings reveal that the adoption of these tools might even be negative when applied at the international level in particular by considering innovation operational practices, and the research suggests for fashion companies the necessity to develop strong markets’ knowledge and brand awareness among foreign markets and customers before investing internationally.

This paper offers an original analytical approach to identifying the relationships between a company’s adoption of e-commerce, performance and internationalisation within the fashion industry.

The purpose of this paper is to identify the most influential determinants of healthcare employees’ problem-solving capabilities and attitudes towards kaizen initiatives, and clarify how these determinants are related to social outcomes.

Drawing on the input-process-outcome framework, applied to kaizen initiatives, the determinants of the input and process factors are embodied in hypotheses concerning the direct effects of input and process factors on social outcomes and the indirect effects of input factors on social outcomes resulting from process factors. The hypotheses are tested through multiple regressions using data from 105 kaizen initiatives drawn from two hospitals.

Of the 14 determinants investigated, goal clarity, team autonomy, management support, goal difficulty and affective commitment to change (ACC) are the most influential determinants of kaizen capabilities and/or employees’ attitude. Goal clarity, goal difficulty, team autonomy and management support are also found to influence social outcomes directly and/or indirectly through ACC, internal processes and/or an action orientation.

The results support healthcare practitioners to understand how to establish “focused kaizen” actions to leverage specific determinants that positively influence social outcomes.

This study provides an original contribution to the literature concerning effective kaizen initiatives in healthcare operations by empirically testing a comprehensive model of the relationship between kaizen initiative determinants and social outcomes. Unlike previous studies, which are mostly anecdotal or focused on one or few determinants, this research adopts a holistic view, and investigates a pluralist set of determinants on social outcomes through a systematic and quantitative approach.

The purpose of this paper is to contribute to the debate on blockchain (BC) adoption for preventing counterfeiting by investigating BC systems where different options for BC feeding and reading complement the use of BC technology. By grounding on the situational crime prevention, this study analyses how BC systems can be designed to effectively prevent counterfeiting.

This is a multiple-case study of five Italian wine companies using BC to prevent counterfeiting.

This study finds that the desired level of upstream/downstream counterfeiting protection that a brand owner intends to guarantee to customers through BC is the key driver to consider in the design of BC systems. The study identifies which variables are relevant to the design of feeding and reading processes and explains how such variables can be modulated in accordance with the desired level of counterfeiting protection.

The cases investigated are Italian companies within the wine sector, and the BC projects analysed are in the pilot phase.

The study provides practical suggestions to address the design of BC systems by identifying a set of key variables and explaining how to properly modulate them to face upstream/downstream counterfeiting.

This research applies a new perspective based on the situational crime prevention approach in studying how companies can design BC systems to effectively prevent counterfeiting. It explains how feeding and reading process options can be configured in BC systems to assure different degrees of counterfeiting protection.

This research intends to investigate whether there are synergies that a firm could or should exploit by simultaneously implementing customer and supplier integration. In particular, the aim is to analyze the impact of customer integration on efficiency, and the moderating role of supplier integration.

This study analyzes data from a sample of 200 manufacturing plants. Two hypotheses are tested through a hierarchical regression analysis. Customer and supplier integration constructs consider items related to different aspects of the integration (e.g. sharing of production plans and customers' forecasts, feedback on performance, communication on quality considerations and design changes, joint quality improvement efforts, close contact, partnerships). The focus of the integration clearly extends beyond the dyad, as it includes the integration of focal operations upstream and downstream, with both suppliers and customers.

Supplier integration positively moderates the relationship between customer integration and efficiency, whereas the analyses do not support the hypothesis that in general customer integration positively impacts on efficiency. They also reveal that, when supplier integration is at a low level, customer integration can even produce a reduction in efficiency.

Efficiency performance optimization requires levering simultaneously on customer and supplier integration to foster their interaction, rather than investing and acting on customer integration only. In addition, before deciding whether to invest in customer integration, managers should ascertain the level of supplier integration, since it acts as a prerequisite for the successful implementation of customer integration.

Compared with previous studies investigating the main impact of customer and supplier integration on a company's performance, this research analyzes a model that considers the interaction effect between these integration strategies. This provides a number of original implications for the interpretation of the relationship between customer and supplier integration and efficiency.

The purpose of this paper is to study whether a fast supply network structure interacts with customer integration (CI) by positively moderating the relationship between CI and efficiency performance.

The authors developed two hypotheses, incorporating dimensions of CI, fast supply network structure and efficiency performance. The hypotheses are tested through a hierarchical regression analysis using data from a sample of 200 manufacturing plants.

CI alone is not enough to guarantee cost reductions because a fast supply network structure acts as a moderator of the CI‐efficiency relationship. The role of this moderator is twofold. On the one hand, it interacts with CI, strengthening the positive impact of CI on efficiency through a positive complementary effect. On the other hand, if the supply network structure is not intended to support fast lead times, the impact of CI on efficiency can be hindered and, in extreme cases, CI can even make efficiency worse.

Efficiency maximization requires levering simultaneously on CI and the supply network structure, rather than investing and acting on CI only. Managers should carefully weigh up the supply network structural context before embracing a CI program, because adopting CI in a wrong context could amplify a series of problems (e.g. nervousness of plans) and offset CI benefits in terms of efficiency.

This study provides an original contribution to the literature on the relationship between CI and efficiency by adopting a contingency perspective, namely assuming that the relationship between supply chain practices and performance is contingent upon how supply networks have been designed. Accordingly, this research questions the assumption that CI always improves efficiency, by analysing the complementary effect between CI and a fast supply network structure. This provides a number of original implications for the interpretation of the relationship between CI, supply network structure and efficiency.
