To conduct any research project it is vital that one knows research design. Designing research is not about planning how to conduct fieldwork: it is also about designing deliverables as well: research creates knowledge, and sharing knowledge is a holistic process. Research design is specifically about how to plan and deliver knowledge in this sense. Yet in the field of design, designing research is not so easy. There are many methods, tools, perspectives and principles to understand complex processes in designing objects, services and systems. For this lecture we look specifically at HCD / Inclusive Design / Service Design to experience&reflect various design research methods.
