I have always purposed research for either marketing efforts, or for design of the product/service. I believe that marketing research and design research ask different questions. Design research fo instance tends to go deeper. I also think that design research can happen prior to and during the design process. I was recently challenged by a college that believe everything prior to the product or project definition is just a variation of marketing research, and design research only happens in stream as testing of potential design solutions.
I find myself wondering what those of you on this list think. How do you define design research? Do you re-purpose marketing research?
