Successful, creative artists and designers engage in many kinds of research beyond a traditional bibliographic approach commonly associated with the arts and humanities. Because they frequently collaborate with professionals from different fields and disciplines, including science, business, and technology, they must be versed in empirical and market research, as well as quantitative and qualitative research approaches that often include product, economic and financial data, demographics, consumers, and statistics. These approaches are key to design research, which often means combining a variety of research and methodological approaches in innovative ways to identify and solve complex design problems.
