The CDIO Initiative is going through a process of reconsidering and updating the CDIOapproach for engineering education development. Previous work resulted in substantialupdates of the twelve CDIO standards and the introduction of “optional” CDIO standards. Thispaper reports on a similar review and update of the CDIO Syllabus to version 3.0. It has beendeveloped by a working group consisting of four sub-groups and iterated and refined guidedby feedback from the whole CDIO community. There are mainly three external drivers that motivate the changes: sustainability, digitalization, and acceleration. There is also an internaldriver in the form of lessons learned within the CDIO community, from using the Syllabus incurriculum and course development. Approximately 70 updates are proposed, amongst themthree additions on the X.X level, namely 1.4 Knowledge of Social Sciences and Humanities,3.1 Teamwork and Collaboration, and 5.3 Research.
