Research is a major part of the design process and is a very complex subject area of its own. The main aim of conducting research is “to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications”. In your Design and Technology course, your research will be used to find the best solution to a problem given the specific limitations (such as time, equipment and funding) you have to work with.
