Journal Article 2025 07 12 In recent decades, digital transformation and emergence of technologies associated with Industry 4.0 have fundamentally reshaped the structure, performance, and competitiveness of supply chains across various industries. This study aimed to identify and elucidate the role of Industry 4.0 technologies in the smartification of supply chains. The research adopted a qualitative approach grounded in Grounded Theory. Data were collected through semi-structured interviews with 10 experts from both academia and industry. For data analysis, we employed Strauss and Corbin’s 3-stage coding method—open, axial, and selective coding. Subsequently, Interpretive Structural Modeling (ISM) was used to hierarchically structure the key concepts and MICMAC analysis was conducted to assess the position of each component based on its driving power and dependency. The findings indicated that the successful implementation of Industry 4.0 technologies in supply chains necessitated the availability of information infrastructure, formulation of a digital strategy, enhancement of human resource skills, and overcoming of cultural resistance within organizations. Additionally, Industry 4.0 technologies were identified as dependent variables in the model with their effectiveness in improving productivity, flexibility, and responsiveness of the supply chain contingent upon the realization of lower-level components. MICMAC analysis further highlighted factors, such as market pressure, digital strategy, and technological infrastructure, as key driving forces in the transformation of supply chains. The practical implications of this research included the development of digital transformation roadmaps, formulation of organizational policies for technology adoption, re-engineering of supply chain processes, enhancement of employees' digital skills, and establishment of national policies related to Industry 4.0. Introduction In recent decades, rapid advancement of digital transformation and emergence of Industry 4.0 technologies have fundamentally reshaped supply chain structures, performance, and competitiveness (Emon & Khan, 2025; Ostadi et al., 2024). Increasing global competition, volatile markets, shorter product life cycles, and the demand for resilient and adaptive operations have compelled organizations to rethink traditional supply chain management and transition toward digital and intelligent ecosystems (Al Mashalah et al., 2022). Industry 4.0 often referred to as the 4th industrial revolution, integrates technologies, such as the Internet of Things (IoT), Artificial Intelligence (AI), Big Data analytics, Blockchain, Augmented and Virtual Reality, Advanced Robotics, and Cloud Computing. These innovations facilitate real-time connectivity, automation, and data-driven decision-making throughout the supply chain (George, 2024; Huang et al., 2023). While these technologies enhance productivity, transparency, and agility, their implementation presents significant challenges, particularly in developing economies. Barriers like a lack of digital infrastructure, inadequate integration of legacy systems, insufficient human resource capabilities, and cultural resistance to technological change remain critical obstacles (Reaidy et al., 2024). In response to these challenges, this study aimed to identify and explain the key factors influencing the successful deployment of Industry 4.0 technologies in manufacturing supply chains. The research sought to address the following questions: (1) What role do Industry 4.0 technologies play in the digitalization of supply chains? (2) What are the barriers to their implementation? and (3) How can a conceptual model be developed to describe the relationships among these factors? Materials & Methods This research employed a qualitative, exploratory-applied design within the interpretive paradigm by using Grounded Theory (Strauss and Corbin) as its primary methodological framework. Data were collected through semi-structured interviews with 10 experts, including academic scholars and industrial managers in the fields of manufacturing and digital transformation. The interview questions were developed based on a systematic literature review and refined through consultations with experts. Purposeful and judgmental sampling techniques were utilized to ensure a diverse representation of expertise. Data saturation was achieved after the 10th interview. The qualitative data were analyzed by using a 3-stage coding process: open, axial, and selective coding. During the open coding phase, 60 primary concepts were extracted from the interview transcripts. These concepts were then categorized into 6 axial categories that represented causal, contextual, intervening, strategic, and consequential conditions. Subsequently, the core category—digitalization of the supply chain through Industry 4.0 technologies—was identified. To validate and structure the relationships among these categories, Interpretive Structural Modeling (ISM) and MICMAC analysis were employed. 11 key variables were selected for ISM modeling and their pairwise influences were analyzed to determine hierarchical levels. The MICMAC analysis further classified the variables based on their driving power and degree of dependence, identifying independent, linkage, and dependent factors. This methodological integration facilitated the development of a robust, multilevel conceptual model that illustrated the dynamic interdependencies among organizational, technological, and human enablers of Industry 4.0 implementation. Research Findings The results indicated that the successful implementation of Industry 4.0 technologies in manufacturing supply chains relied on a series of interconnected organizational, technological, and human factors. The ISM analysis identified 6 hierarchical levels. The foundational layer consisted of market pressure and competition followed by the need for transparency, a shortage of digital skills, and cultural resistance. The mid-level included technological infrastructure and digital strategy, while the upper levels encompassed employee training, systems integration, and ultimately the adoption of Industry 4.0 technologies. These factors led to enhanced productivity, cost reduction, flexibility, and responsiveness. The MICMAC analysis classified "market pressure", "digital strategy", and "IT infrastructure" as driving (independent) variables, while "integration", "skills", and "training" were identified as linkage variables—both influencing and being influenced by other factors. The dependent variables—"productivity improvement", "cost reduction", and "supply chain flexibility"—represented the ultimate performance outcomes. Furthermore, the study found that technological adoption alone was insufficient; it required complementary enablers, such as management commitment, employee empowerment, and a supportive digital culture. The results also highlighted that technologies like AI, IoT, Big Data, and Blockchain could significantly enhance real-time monitoring, traceability, decision-making accuracy, and transparency. However, their effectiveness was contingent upon organizational readiness, infrastructure maturity, and strategic alignment. Discussion of Results & Conclusion The study concluded that Industry 4.0 technologies served as critical yet dependent enablers in the digital transformation of supply chains. Their effectiveness hinged on the prior establishment of a coherent digital strategy, a robust technological infrastructure, and a digitally skilled and motivated workforce. The ISM–MICMAC-based conceptual model–illustrated that digital transformation followed a hierarchical cause-and-effect progression: from strategic and infrastructural readiness to technological implementation, culminating in performance outcomes. 5 major barriers were identified: (1) the absence of a comprehensive digital roadmap, (2) inadequate IT infrastructure, (3) a shortage of digital skills, (4) cultural resistance to change, and (5) insufficient structured training programs. Addressing these barriers necessitated an integrated approach that encompassed strategic governance, investment in infrastructure, process re-engineering, and human capacity building. Practically, the findings offer managerial guidelines for designing effective digital transformation roadmaps, developing training and motivation systems, and formulating organizational policies to enhance readiness for Industry 4.0 adoption. Theoretically, this research contributes to the growing body of literature on smart supply chains by providing a contextually grounded conceptual model that bridges the gap between technological potential and organizational capability. Future research could extend this work by quantitatively validating the proposed model across various industries and regions.
