Prototyping Twitter Video
A good diary-style account of the decisions enabled by making prototyping part of the design process. Today’s best engineers understand the bare-minimums expected for screen transitions and animation. Prototyping everything is a waste of time. I find it far more productive to use that time to use high-fidelity prototypes to test new ideas. These are ideas that make sense in your head but invariably require several rounds of tweaking before they are actually usable.
