A discussion of the methodologies of researchers in art and design: should they adopt and adapt methodologies from other academic disciplines or develop original approaches unique to the quality of discovery in art and design? In the key area of research by project, where the end product is an artefact, the need to develop original research methodologies seems essential. This paper reviews the methodologies of three Royal College of Art-based research-by-project doctoral students - Ian Ferguson, Les Johnson, and Anthony Dunne - who have begun to develop unique research strategies.
