I’m also currently working on my capstone project, and we also broke down the project into categories. We split up the project into hardware and software. The project is developing a smart-cast, a cast that can measure the degree of inflammation around the affected area and give a more accurate representation of the healing process. We further split up the hardware into categories based on components and the software based on the hardware components. We could have tried a different method, but since our project is built from so many components, using a category system was more beneficial to us in the long run because it allowed us to focus on each component separately before creating a system design. If we had to do it differently, perhaps a phase breakdown would also be suitable. Hardware and software would be developed simultaneously, and each phase would constitute a different component.
