According to Klaus Schwab, the founder and chairman of the World Economic Forum, Industry 4.0 requires a multi-perspective approach to problem-solving, where we leverage the strengths of multiple disciplines, technologies, and ways of thinking to create innovative solutions. To equip engineers for the Industry 4.0 era, the engineering curriculum needs to provide a well-rounded education that includes exposure to diverse engineering fields, computing technologies, and non-engineering subjects, in addition to their core discipline. Computer Science and Engineering programs should supplement computer science courses with physical engineering-related courses. Collaborative, interdisciplinary courses should be jointly developed that combine elements of physical engineering, mathematics, and computing and be taught by faculty from multiple departments. Active demonstration of interdisciplinary teamwork by faculty through these courses is crucial to fostering such skills among students.

Common engineering core courses should include topics related to mechanical mechanisms, CAD, computer programming, contemporary production and construction techniques, digital electronics and embedded systems, engineering measurements, mechanical and electrical machines, digital signal processing & communications, automation & control systems, sensors, actuators, data analysis, IoT, etc. Each University can integrate these topics differently based on its strengths and focus, creating different sets of interdisciplinary courses. Conventional mathematics courses in the engineering curriculum can be transformed into computational engineering modeling courses, providing students with a contextualized and integrated understanding of mathematics across various engineering disciplines. Finally, active, integrative, reflective, and collaborative pedagogical engagements are even more crucial for shifting towards outcome-based education (OBE) in engineering education.
