Last week I wrote a post about the fidelity level of design prototypes. This topic has been on my mind for some time. Shortly after making last weeks post I created another graph that I think is noteworthy. Much like last weeks graph/post I have no quantitative research to back this up. I have been studying design and designers for a couple of decades now and these two posts reflect my personal experiences. Today's graph reflects how an experienced designer might create prototypes of increasingly high fidelity as a design project progress from its early stages to it later/final(?)/ship state. As with last weeks post this progression may depend on the type of design project that a designer might be working on and the client that the designer is working with. Sometimes it might be appropriate to create prototypes at a very high level of fidelity much earlier in the design process. So, these graphs are intended as rough "rule of thumb" models.
