This account of practice focuses on an augmented Customer Development methodology which the author adopted for a module in a Master's program in Entrepreneurship at a Swedish business school. The article details the techniques underlying this augmented methodology, and the journey toward its implementation. By conceptualizing "hypotheses" as testable statements linking together blocks of the Business Model Canvas, and "assumptions" as students' assessments of the contents of each block at the outset of the process, the author provides a more pedagogical as well as a more scientifically and theoretically consistent model. Its effectiveness was assessed through discussing these changes with students who had recently taken the course prior to the author's appointment as teacher. Adaptations such as this could provide an effective method for teachers who want to update an existing course, or who have recently been appointed to a new course focusing on practical aspects of entrepreneurship. Alternatively, it could help to inspire teachers who wish to augment course content to draw more on coherent theory building and good scientific practice, as are most often suited to Master's level studies, but without radically altering the lesson plan, syllabus or reading material.
