Flash It is a rapid concept communication technique in which a designer presents a rough idea (a sketch, a photograph, a paragraph, or a prop) to a colleague or potential user for a very brief 'flash' of exposure, then asks for an immediate, unfiltered reaction. It is faster and less formal than a review session and less resource-intensive than a usability test: it is a thirty-second conversation that can happen in a corridor, at a desk, or via a shared photo. The brevity is what makes it valuable, the reaction captures first impression, not constructed opinion.
