This totem pole-style monstrosity of a chart you are looking at represents the perpetual beta state of good service design. I’ve snagged and manipulated Jesse James Garrett’s beautiful chart, The Elements of User Experience. Download the original pdf here and marvel that this was done in the year 2000. Garrett was clear that his picture is incomplete, that it does not “account for secondary considerations” and that it “does not describe a development process”. Just for thrills and in the crudest of ways I tried to add that dimension to his chart; the iterative development process is illustrated with repetition. Enjoy.
