This study aims to propose the Shingo 5.0 model, which integrates the Shingo model with Industry 5.0, with the aim of ensuring not only internal cultural transformation but also the sustainability of the broader ecosystem. It is intended to enhance stakeholder engagement, strengthen the resilience of the entire value chain, including the supply chain, and improve environmental, social and ethical sensitivity. The primary objective is to determine the importance weights of this new model structure.
The integration of the Shingo model and Industry 5.0 is proposed based on the theoretical foundations of an individual-centered approach. The dimensions and principles created for the proposed Shingo 5.0 model are detailed. To determine the importance weights of these dimensions and principles, the Fermatean Fuzzy Piprecia method was used.
The Shingo 5.0 model enables not only more reliable production but also fosters greater environmental and social sensitivity. It contributes to strengthening not only internal company structures but also the supply chain, creating a system where all stakeholders are empowered and contribute actively. Rather than being subordinate to technology, employees become the core around which technology is developed as a supportive tool. The technical practices and cultural perspective of the Shingo model also constitute other strengths of the model. Moreover, to better understand and manage the relevance of this new model, the importance weights of its three dimensions and ten principles were calculated using the Fermatean Fuzzy Piprecia method. To ensure the reliability of experts’ evaluations, the Delphi method was used. The sensitivity of the results was tested across three different sectors by experimenting with alternative scenarios in decision-maker weightings and validating the robustness of the method through the application of the Fermatean Fuzzy SWARA approach. The findings indicated a high degree of consistency and reliability among the results. Among the three dimensions of the model, the most critical is smart advancement systems, followed by structures for enabling human potential. The dimension integrated sustainable value creation ranks third. Among the principles, the most important is strengthen each human, followed by lead by common vision.
Applications of the Shingo 5.0 model are expected to be adopted by many companies in the near future. The growing importance of concepts such as sustainability, people, cultural transformation, technology, efficiency and supply chain resilience will distinguish this model in the long term. However, real-world implementation of this model and comprehensive analysis of its results are still required.
To the best of the author’s knowledge, this research is the first to integrate the Shingo model with Industry 5.0. It also stands out for its originality in evaluating the importance weights of the model’s criteria using one of the most up-to-date methods – the Fermatean Fuzzy Piprecia method. The weighting procedure in this hierarchical framework was implemented to establish priorities for continuous improvement efforts, ensure the effective utilization of organizational resources, define key strategic focus areas and support the direction of design-driven initiatives. Accordingly, the calculated weights were not solely intended to contribute theoretically but were also structured to strengthen their managerial relevance and applicability within real-world decision-making and execution contexts.
