This paper provides a survey on recent research in the area of design rationale. The study of design rationale spans a number of diverse disciplines, touching on concepts from research communities in mechanical design, software engineering, artificial intelligence, civil engineering, computer-supported cooperative work, and human-factors and human-computer interaction research. We focus this survey on prototype design rationale systems for these application domains, and put forward several major criteria with which to describe and classify design rationale systems, including argumentation-based, descriptive, process-based approaches. Further, we attempt to abstract the place of systems and tools for design rationale capture and retrieval in the context of contemporary knowledge-based engineering and Computer-Aided Design (CAD) tools. This survey is structured around classes of fundamentally different approaches, their representation schema, their capture methods and retrieval techniques. A number of recent design rationale systems, including JANUS, COMET, ADD. REMAP, HOS, PHIDIAS, DRIVE and IBIS are analysed. We conclude with an assessment of current state-of-the-art and a discussion of critical open research issues.
