Writing Specs Designs
If you're stuck between whiteboard sketches and pixel-perfect mocks, this gives you a framework for figuring out what fidelity you actually need. It pushes you toward prototypes over documentation, which is the right instinct but hard to stick to under deadline pressure. The core tension it navigates well is Wodtke's "draw badly to invite collaboration" versus Bier's "products live and die in the pixels." Those aren't contradictory, they're about different stages, and the skill helps you figure out which stage you're in. The fat marker sketch concept from Ryan Singer is worth the price of admission alone.
