Design Process | A Mapping of User Interfaces

Over the last few years of school I have been shown various renditions of the design process. Although each valid, I feel they contradict each other in their own ways. My main concern with many of the current design process diagrams is they have discrete steps that you then return to throughout the recursive method. My final design is a circular 'clock' that shows the recursive project timeline and the overlapping of roles.
