Another idea that I find useful to layer on the design process is the consideration of the spectrums of current state to future state (x-axis), and concrete to abstract (y-axis), the above inspired by the Analysis-Synthesis Bridge Model (Dubberly, Evenson, & Robinson). We generally start with concrete information about the current state (lower left quadrant), and with this data about how the world is we synthesize an abstracted model of the current state (upper left quadrant). We then design an abstrated vision of the future state (upper right quadrant) and then work make real that vision of the future (lower right quadrant).
Current / Future _ Abstract / Concrete
