The introductory design course in Mechanical and Industrial Engineering at Ryerson University combines Human Factors (HF) and Design. Due to its unique character, we have developed custom courseware. In recent years the instructors have noticed four specific shortcomings in students’ abilities to incorporate HF into their designs. We are developing new courseware that focuses on embedding HF considerations into the requirements specification stage. The courseware incorporates a novel combination of Hierarchical Task Analysis (a well-known method) with Usage Scenarios (a method of Salustri’s invention, based on the work of Stone and Wood). We further alter the courseware in several other ways to minimize the amount of documentation that students need to provide, while still capturing their decision-making process well enough to allow appropriate assessments. A plan for implementing and assessing the proposed work is also presented. Keywords: engineering design, human factors, hierarchical task analysis, courseware, user experience
