Book excerpt: Doing research can make all the difference between a great design and a good design. By engaging in competitive intelligence, customer profiling, color and trend forecasting, etc., designers are able to bring something to the table that reflects a commercial value for the client beyond a well-crafted logo or brochure. Although scientific and analytical in nature, research is the basis of all good design work. This book provides a comprehensive manual for designers on what design research is, why it is necessary, how to do research, and how to apply it to design work.
