Abstract

Effects of a Structured Prototyping Strategy on Capstone Design ProjectsPrototyping is often a very important phase in a capstone design project. However, in manycases, prototyping decisions are made arbitrarily by students, adversely affecting the quality ofthe final product delivered. At the University of ________ we are developing a structuredprototyping strategy tool based on a synthesis of prototyping techniques that have been shown tobe effective. Our strategy tool leads designers through the process of making decisions aboutaspects of a prototype program, such as how many concepts to prototype, how many iterations tocomplete for a given concept and whether to use scaled prototypes. In this study we evaluatewhether explicit discussion of these prototyping decisions affects the results of the capstonedesign projects. At the beginning of the semester, two researchers presented the prototypingstrategy tool to the students and elaborated upon the benefits of the same. The researchersconducted interviews at the end of the semester to evaluate the success of the prototyping effortmade by the students. These results were compared to previous capstone projects where thestudents were not exposed to such a prototyping tool. The results of the comparison showstatistically significant increases in the proportion of teams opting to create prototypes and theaverage number of prototypes per team. This paper describes the study in detail, analyzes theresults, and presents conclusions and future directions of the research.
