"Although the point may seem like common sense, few design projects make any explicit provision for this kind of conceptual work before making irreversible design commitments.... A design process that does not analyze its concepts forecloses much of the design space before it even begins, and risks catastrophe if its concepts are broken. And because the same potentially problematic concepts are used in evaluating the system that is designed, fundamental design flaws will not necessarily be detected."
