Research design is a specific outline detailing how your chosen method will be applied to answer a particular research question. Research methods are generalized and. Design research was originally constituted as primarily research into the process of design, developing from work in design methods, but the concept has been expanded to include research embedded within the process of design, including work concerned with the context of designing and research-based design practice. The concept retains a sense.
