Lean Six Sigma (LSS) is often perceived as a foundation for implementing Industry 4.0 (I4.0) within an organization, with the two strengthening each other in different ways. The purpose of this article is to examine the evolution, trends and motivation for merging LSS and I4.0 and to gain insights into LSS 4.0 in both manufacturing and service sectors. This article also explores the effective methods for integrating and implementing LSS 4.0 in both manufacturing and service sectors, along with conducting a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis of LSS 4.0.

By conducting a systematic literature review in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant literature from 2010 to 2023 was reviewed using appropriate keywords and research criteria. The objective was to identify, select and evaluate research articles related to LSS 4.0. Consequently, 159 relevant papers were located in databases, including Elsevier, Taylor and Francis Group, IEEE, Springer, Emerald Insights, Scopus and non-Scopus databases. Additionally, this review aimed to understand the progress of LSS 4.0 from the manufacturing and service sector context and to perform a SWOT analysis of LSS 4.0.

This review reveals a significant surge in the literature on LSS and I4.0 over the past three years. The research articles were categorized based on various themes, including the publisher, journals, types of articles and geographical factors such as country and continent. Additionally, the review examined the progress of LSS 4.0 in both manufacturing and service sectors. A SWOT analysis was also performed to identify the SWOT of LSS 4.0.

This is the first exclusive research work to conduct a SWOT analysis of LSS 4.0. This research article is highly valuable for academicians, researchers, policymakers and practitioners as it helps to identify the SWOT of LSS 4.0. Furthermore, it provides an overview of the progress of LSS 4.0 from both manufacturing and service sector perspectives, and significant case studies are discussed.

This study developed a theoretical model to test the relationship between digital capability and Industry 4.0 (I4.0) and its effect on innovation performance in small and medium-sized enterprises (SMEs).

The proposed theoretical model was evaluated using partial least-squares structural equation modeling and fuzzy-set qualitative comparative analysis. The data were obtained from a sample of 536 SMEs in Chile.

The proposed model presented two dimensions of digital capability: management and information and communication technologies (ICTs). Management models composed of enterprise resource planning and customer relationship management systems are essential for optimizing organizational management. Meanwhile, ICTs facilitate the smooth flow of information within an organization, leading to improved efficiency in production processes. I4.0 is encouraged by exposing SMEs to base technologies such as data analytics. These results confirm that I4.0 influences innovation performance.

SME managers should encourage the development of digital capabilities to transition toward I4.0, as this can make SMEs more competitive and innovative in changing and dynamic scenarios.

I4.0 adoption and the development of digital capabilities can directly affect employment and national economic growth.

Most studies focus on the organizational factors affecting SMEs’ I4.0 adoption. They do not, however, address the role played by current digital capability in I4.0 technology adoption and its effect on firms’ innovation performance.

Este estudio desarrolló un modelo teórico para probar la relación entre la capacidad digital y la Industria 4.0 (I4.0) y su efecto en el desempeño de la innovación en pequeñas y medianas empresas (PYME).

El modelo teórico propuesto se evaluó mediante el uso de modelos de ecuaciones estructurales de mínimos cuadrados parciales y análisis comparativo cualitativo de conjuntos difusos. Los datos se obtuvieron de una muestra de 536 pymes de Chile.

El modelo propuesto presenta dos dimensiones de la capacidad digital: la gestión y las tecnologías de la información y la comunicación (TIC). Los modelos de gestión compuestos por sistemas de planificación de recursos empresariales y de gestión de relaciones con los clientes son esenciales para optimizar la gestión organizacional. Por su parte, las TIC facilitan el flujo fluido de información dentro de una organización, lo que conduce a una mejora de la eficiencia en los procesos de producción. La I4.0 se fomenta exponiendo a las PYME a tecnologías de base como el análisis de datos. Estos resultados confirman que la I4.0 influye en el rendimiento de la innovación.

La mayoría de los estudios se centran en los factores organizativos que afectan a la adopción de la I4.0 por parte de las pymes, pero no abordan el papel que desempeña la capacidad digital actual en la adopción de la tecnología I4.0 y su efecto en el desempeño innovador de las empresas.

Los gestores de las PYMES deben incentivar el desarrollo de capacidades digitales para realizar la transición hacia la I4.0, ya que esto puede hacer que las PYMES sean más competitivas e innovadoras en escenarios cambiantes y dinámicos.

La adopción de la I4.0 y el desarrollo de capacidades digitales pueden afectar directamente al empleo y al crecimiento económico nacional.

Acknowledging the importance of both lean thinking (LT) and Industry 4.0 (I4.0) for successful business performance and organisational success, the present study investigates the critical success factors (CSFs) for the concurrent implementation of both approaches, a field not yet significantly explored.

The study conducts two systematic literature reviews (SLRs), one on LT and the other one on I4.0 to map out the CSFs for the effective implementation of each approach. These CSFs are subsequently prioritised with the use of a Delphi Study. Finally, from the set of the common CSFs recognised through the two approaches, a more condensed list is put forward as the first step towards achieving a successful synergy between LT and I4.0.

The study’s findings suggest the most important CSFs and determine their definition in the context of a concurrent implementation of LT and I4.0. This can provide managers and practitioners with the awareness of crucial factors, enabling them to take the necessary steps for planning and implementing both approaches.

A concise set of CSFs for the concurrent implementation of both LT and I4.0 has been identified, which can be viewed as a starting point for providing top executives and managers with useful insights into enhanced business efficiency and performance. This study furthermore contributes to the overall body of knowledge on LT and I4.0.

The scholarly literature that explores a common set of CSFs for the concurrent implementation of LT and I4.0 is limited. This gap significantly enhances the importance of the present research, contributing to a better understanding amongst both academics and practitioners of the key supporting factors for the integration of the two approaches.

The efficiency-enhancing and performance-boosting benefits of lean six sigma (LSS) practices have been advocated in both academia and industry. However, their mediating and moderating effects remain unclear and the impact of LSS practices is underdeveloped in the Chinese context. Therefore, by focusing on publicly listed companies in China, this study aims to investigate whether, how and when LSS practices link to organizations’ innovation and financial performance.

Data from 66 Chinese publically listed companies spanning a period of 25 years (2000–2024) was analyzed using the difference-in-difference method which compared the changes in outcomes over time between a treatment group and a control group.

This research found that LSS practices are positively related to firm-level outcomes including innovation and financial performance. The authors also confirm the mediating effect of operational capability on these relationships. Moreover, the empirical evidence suggests that implementing the quality management systems (QMS) standard, ISO 9001, moderates the relationships between LSS practices and innovation and financial performance such that these relationships are stronger for firms in organizations with higher maturity levels in implementing the standard.

This study sheds light on LSS theory and offers valuable recommendations for lean managers on how to leverage LSS practices to improve their innovation and performance capabilities.

This research provides novel insights into the influence of LSS practices on firm-level outcomes such as the level of innovation and financial performance. To the best of the authors’ knowledge, this study is the first to theoretically propose and empirically validate how and when LSS practices influence firm outcomes by introducing the mediating mechanism of operational capability and the boundary condition of QMS standards.

This study utilised the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) declaration as a review protocol, and the data is retrieved accordingly. Therefore, 104 articles from Scopus and 28 from Web of Science were combined in R-Environment, and 25 duplicates were removed using RStudio. Finally, 107 papers were selected for further analysis. After the abstract level screening, the study reviewed 99 articles bibliographically published in peer-reviewed journals from prominent academic databases Scopus and WoS between 2011 to April 2023. We used the VOSviewer software tool for analysing bibliometric networks that allow the construction, visualisation, and exploration of maps based on any form of network data.

The review identified emerging themes: artificial intelligence, digitalization, sustainability, root cause analysis, topic modelling, and digital voice-of-customers. To establish the intellectual structure of the field and identify gaps, co-citation and content analysis were used. The content of 49 papers in the identified clusters was then carefully analysed. The four primary themes are the relationship of Quality 4.0 with Industry 4.0, the conceptualization of Quality 4.0, recommendations for the new Quality 4.0 model, and the impact of Quality 4.0. The findings provide an excellent foundation for future research in this field for policymakers, managers, practitioners, and academia.

This is the first systematic literature review-cum-bibliometric analysis on quality 4.0 that covers the field comprehensively. Based on the present review, the paper proposes six possible future research directions to investigate.

The integration of Lean Six Sigma (LSS) and Industry 4.0 (I4.0) is in the nascent stage and promises to achieve new optimums in operational excellence. This study aims to empirically examine the enablers, barriers, benefits and application of I4.0 technologies in LSS and I4.0 integration.

A pilot survey was chosen as an appropriate methodology, as LSS and I4.0 integration is still budding. The survey targeted senior quality management professionals, quality managers, team leaders, LSS Black Belts and operations managers to collect the relevant research data. The questionnaire was sent to 200 respondents and received 53 valid responses.

This study reveals that “top management support” is an essential enabler for LSS and I4.0 integration. The most significant barrier was “poor understanding of data analysis” and “lack of top management support”. The findings further illustrated that LSS and I4.0 integration resulted in greater efficiency, lower operational costs, improved productivity, improved customer satisfaction and improved quality. Regarding I4.0 technology integration at different phases of LSS, the authors noticed that big data analytics and artificial intelligence (AI) are the most prominent technologies used in all phases of LSS implementation.

One of the limitations of this study is the sample size. LSS and I4.0 are emerging concepts; hence, obtaining a larger sample size is difficult. In addition, the study used non-parametric tests to analyse the data. Therefore, future studies should be conducted with large sample sizes across different continents and countries to understand differences in the key findings.

The outcomes of this study can be useful for organisational managers to understand the enablers and barriers before integrating LSS and I4.0 for adoption in their organisations. Secondly, it helps to convince top management and human resource personnel by providing a list of benefits of LSS and I4.0 integration. Finally, it can help decision-makers understand which I4.0 technologies can be used in different stages of LSS methodology.

LSS and I4.0 integration was studied at a conceptual level. This is the first empirical study targeted toward understanding the LSS and I4.0 integration. In addition, this study investigates the application of widely used I4.0 technologies in different phases of LSS.

The integration of front-end technologies such as automation, process simulation and augmented reality with Just-in-Time (JIT) practices can yield unforeseen outcomes in manufacturing due to complex dynamics. This study examines this integration’s impact on manufacturing firms' performance.

We design a survey questionnaire and distributed it among 353 Brazilian manufacturing firms to conduct our investigation. We utilize a combination of factorial and regression analyses with moderation within our final sample, composed of 262 manufacturing firms. Our goal is to examine the impact of aligning front-end technologies and JIT on the operational and economic performance of these manufacturing firms. We adopt complexity theory as our theoretical framework, recognizing and accommodating the intrinsic unpredictability and uncertainty inherent in complex scenarios such as technology adoption and its interplay with firm culture, adoption time and technology adoption resistance.

Our findings indicate that JIT influences the use of front-end technologies both positively and negatively. Regarding operational performance, JIT has a positive moderation effect on automation and a negative moderation effect on process simulation. Conversely, for economic performance, JIT positively moderates process simulation and negatively moderates automation.

We provide empirical evidence for managers to carefully assess the compatibility of technology adoption strategies with existing organizational culture and operational practices to maximize performance outcomes.

Our study advances complexity theory by elucidating the impacts of integrating front-end digital technologies with JIT practices within the unique scenario of the Brazilian manufacturing industry. More specifically, our theoretical framework offers a new perspective on the unpredictable nature of performance outcomes regarding technology adoption in operations.

To deal with an increasingly competitive environment, organizations are combining continuous improvement (CI) practices with digitalization to accrue their benefits on operational performance and achieve operational excellence. The purpose of this study was to identify the enablers and inhibitors of digitalization as part of CI projects.

A mixed-methods sequential explanatory research design consisting of an online survey and semi-structured interviews was used to examine how digitalization technologies have been incorporated by organizations in their CI projects.

Key enablers of digitalization were found to be leadership capabilities, strategic direction, stakeholder involvement, system compatibility, data quality and giving employees room to experiment. Knowledge of digitalization was found to affect all these enablers.

The empirical findings are based on a nonprobability sample of Dutch CI practitioners, limiting their generalizability.

The empirical findings highlight the need for organizations to adopt a structured approach to implementing digitalization as part of their CI projects, starting by ensuring that the necessary knowledge and skills are either present or accessible to the organization.

The empirical findings show that enablers of digitalization in the context of CI are strongly interlinked, and thus require a holistic approach.

This paper aims to identify leadership behaviours in the manufacturing sector in Jordan that enable successful Lean Six Sigma implementation.

Qualitative data were collected through 27 interviews to identify the leadership behaviours that facilitate Lean Six Sigma and a focus group to categorise the aspects by grouping them into themes. A grounded theory approach was used in the field study. The processes of constant comparisons helped in identifying the relevant aspects of leadership behaviours and integrating specific aspects into themes; these processes were iteratives. Therefore, this research project relies on the grounded theory methodology to collect and analyse the data. The authors also used a focus group to categorise the aspects by grouping them into themes. In that, the aspects were grouped around core categories.

After analysing the data, 36 aspects have emerged. The data analysis processes helped in discovering the aspects of leadership that support the use of Lean Six Sigma in the manufacturing sector in Jordan. The aspects were developed through an iterative process of analysis until the saturation level was reached. Eight themes that influence the successful use of Lean Six Sigma emerged: Training and development; Continuous improvement and development; Communication; Empowering employees; Motivating employees; Managing qualities and operations; Employees engagement and involvement; and Supporting culture

There are some research limitations to this study, which opens avenues for future research. First, the data was collected through qualitative methods, which limits the generalizability of the results. Future studies are needed to generalize the results to the wider business community. Second, the data was collected only from manufacturing organizations and did not consider other sectors. Future researchers are urged to replicate the study in other sectors. Third, this study considered only Jordanian firms; therefore, the authors call upon further research to investigate other national settings that may have a different business culture.

This study encourages businesses to follow and adopt these behaviours in organisations, which can help in developing desirable behaviours among leaders to reach advanced levels in using Lean Six Sigma. Moreover, practitioners can develop training programmes for developing leaders. Thus, the Lean Six Sigma journey can become smoother by addressing the issues that face practitioners during the different phases of implementing Lean Six Sigma. In that respect, the practical implication of this research is to describe the practices that the leadership of organisations must develop to maintain high levels of Lean Six Sigma deployment.

Scholarly studies in this field are scarce, especially in developing countries, so identifying the leadership behaviours can help researchers create a theory of leadership behaviours for Lean Six Sigma. Furthermore, practitioners of Lean Six Sigma can take into account these behaviours as crucial to the effective use of Lean Six Sigma. They can encourage leaders to follow and adopt these behaviours in organisations which can help in developing desirable behaviours among leaders to reach advanced levels in using Lean Six Sigma. Thus, the Lean Six Sigma journey can become smoother by addressing the issues that practitioners face during the different phases of implementing Lean Six Sigma.

The view that dynamic capabilities theory can help explain how lean organizations improve has been put forward by scholars. However, there is still a lack of research on the matching relationship between the application of lean practice and the internal elements of enterprise organization from the perspective of dynamic capabilities. The purpose of this study is to validate the moderating effect of dynamic capabilities on the relationship between lean practices and operational performance.

This study used the method of survey and empirical research to collect sample data from 263 enterprises in China. Through literature review, this study put forward the moderating hypotheses around dynamic capabilities, lean practices and operation performance and used the method of regression analysis to validate these hypotheses.

The results showed that dynamic capabilities have a partially moderating effect on the application of lean practices. Specifically, dynamic capabilities have a significant moderating effect on the relationship between just-in-time, total quality management, total preventive maintenance and operational performance, while dynamic capabilities have no significant moderating effect on the relationship between human resource management and operational performance.

The research conclusion complements and enriches the lean practices literature from the perspective of dynamic capabilities. Existing studies mainly focus on the moderating role of external environmental factors, while there is a lack of empirical research on the role of dynamic capabilities in lean practices literature. The research results will help enterprises further understand the matching relationship between lean practices and dynamic capabilities and then improve the success of lean practices application.
