Designers ask questions throughout the design process. The resulting arguments about how best to answer them are critical in justifying solutions, but are rarely recorded. We are developing a representation of design rationale called QOC (Questions, Options and Criteria) which captures just such information (MacLean et al, 1991). It encourages evaluation of a broader range, or design space, of solutions than designers might otherwise consider.
