The manufacturing sector is undergoing a fundamental shift driven by the twin transformation—the simultaneous integration of digital and green transformation. This transition reshapes industrial processes and necessitates a workforce equipped with interdisciplinary skills that bridge technological expertise, sustainability principles, and strategic business acumen. However, existing workforce development strategies remain fragmented, lacking a structured theoretical foundation for skill integration. This paper presents a conceptual and theoretical study that introduces the Talent Triangle Framework, a novel model categorizing essential competencies for twin transformation into three interdependent domains: digital, green, and business skills. Grounded in human capital theory, dynamic capabilities theory, and the skill-biased technological change hypothesis, the framework systematically examines the intersections of these skill domains, providing a structured lens for understanding workforce readiness in the evolving industrial landscape. By offering a theoretically driven perspective, this study highlights the strategic implications of hybrid skill development for industrial competitiveness and policy-making, emphasizing the need for interdisciplinary learning models, reskilling strategies, and adaptive workforce policies. The Talent Triangle serves as a conceptual blueprint for aligning digital and green transformation with business strategy execution, laying the groundwork for future empirical research and practical implementation. While empirical validation remains a future research priority, the framework offers a robust theoretical foundation for exploring interdisciplinary upskilling strategies in manufacturing.
