A multi-billion dollar chemical company (DupontCanada) developed, over twenty years, a unique leadership philosophy and practice that was instrumental in the company’s remarkable improvement and great financial and societal success. The beliefs that are fundamental to this Developmental Leadership model are: values are the foundation of leadership; everyone can learn to lead; leaders develop role model leading competence through learning certain skills, character attributes and purposeful behaviours; the work of leaders in organizations is developing high performance work systems dedicated to achieving sustainable growth; and learning to be a better leader is a life-long endeavor. A leadership course for engineering students based on this was developed by the former CEO and Chairman of the company (first author David Colcleugh), an engineer by training, and has been offered to undergraduate and post-graduate engineering students at the University of Toronto since 2007. At first the course was offered as a combined undergraduate-graduate course. In 2011 it was decided to offer separate coursesfor graduate students and undergraduate students. Atextbook, Everyone a Leader, was prepared (byColceugh) and beginning in 2012 was used, in manuscript form, in both courses. The textbook provided the curriculum and instructional framework that permitted a second instructor to lead the course –(second author Doug Reeve). The Developmental Leadership Model serves as a framework for instruction so long as the instructor’s own leadership experience is well integrated into course discussions. The course hasnow been offered eight times.The motivation for the course arises from the belief that engineering students should, in addition to having strong scientific and technical capabilities and being self-motivated to contribute, should be well prepared emotionally, socially, and ethically to accept challenges and should be to committed to develop non-technical as well as technical competencies.
