Integrative problem solving has emerged as a crucial competency in the evolving landscape of engineering education and management, where complex challenges demand multidimensional and collaborative approaches. This study aims to develop a comprehensive framework for Integrative Problem Solving (IPS) that bridges analytical reasoning, creative design, and managerial decision-making. Drawing from systems thinking, design thinking, and experiential learning theories, the proposed framework synthesizes cognitive, technical, and socio-organizational dimensions to enhance problem-solving effectiveness. The study employs a mixed-method approach that includes literature synthesis, expert validation, and pilot application within engineering and management learning environments. Results highlight that integrative problem solving improves adaptive thinking, interdisciplinary communication, and decision quality. The proposed model also facilitates alignment between academic instruction and real-world managerial contexts, fostering innovation-driven learning ecosystems. This framework provides actionable insights for educators, curriculum designers, and organizational leaders seeking to cultivate integrative competencies among future engineers and managers. It emphasizes the transformation from traditional silo-based instruction toward a holistic educational paradigm grounded in collaboration, reflection, and systems-oriented inquiry...
