This work delves into the integration of CDIO principles within first-year integrated group projects, highlighting collaborative efforts within discipline-specific groups, diverse project deliverables, and the unique emphasis on the Project Showcase for assessment. The integration of CDIO has been applied to methodologies within first-year integrated group projects in Mechanical, Chemical, and Food Bioprocesses Engineering. Students collaboratively conceive solutions to engineering challenges within their respective disciplines. The group dynamic fosters creative thinking, problem-solving, and discipline-specific collaboration. The projects involve diverse deliverables, with the final assessment placing a higher weight on the collective group performance during the Project Showcase. This live demonstration is a pivotal evaluation moment, integrating CDIO principles into a real-world context. The showcase not only provides a platform for students to communicate their design rationale, operational strategies, and project outcomes to a broader audience but also places a heightened emphasis on the collective group performance during this interactive and operational presentation. Graduates emerge with not only technical proficiency but also with the invaluable skills of teamwork, communication, and adaptability, which are essential attributes for success within their chosen engineering field.
