Over the last 10 years we have seen a growing number of researchers integrating design experiments in their research inquiries. Initially, this work borrowed heavily from neighboring fields, employing a dual strategy in which design experiments and their evaluation were largely treated as separate processes that were often carried out by different people. More recently, design researchers have developed several approaches that integrate design-specific work methods into research. This paper takes a methodological look at three such established approaches that the authors call Lab, Field, and Gallery. They are described and their similarities and differences analyzed. In conclusion, whether design research today needs foundations based on the standards established for other disciplines is discussed.
