Addressing the subject of Case-Based Reasoning in design, this article reports on a series of
in-depth interviews with expert architects/design teachers about the role of cases in design
practice and education. Several ingredients of the Case-Based Design (CBD) recipe turned
out to occur in real-world design, be it in a subtler version than CBD researchers usually
assume. The article focuses primarily on design in architecture, yet the findings may be
relevant for other design domains as well.
