Design Theory and Methodology
Faculty of Industrial Design Engineering
Aim: Understanding the design process
Theoretical basis: reflective practice (Schön, 1983)
Aim: evaluation of the use of methods in particular phases of design
Aim: evaluation of the use of words, concepts and assumptions during the design process
Aim: to analyse ethical judgments in the design process
how to get meaningful results?
“People who write about methodology often forget that it is a matter of strategy, not of morals. There are neither good nor bad methods, but only methods that are more or less effective under particular circumstances in reaching objectives on the way to a distant goal.” (Homans, 1949)
Protocol analysis of design activity:
Two basic assumptions:
Empirical Results: Designers rarely do follow these predefined procedures
does not relate to situational characteristics, such as time-constraints
does not relate to the socialcontext, such as cooperation and conflict
Humans tend to reduce complexity in order to reduce cognitive load.
Perceived difficulty of a task and the non-availability of solutions reduce one’s feeling of competence and self-efficacy.
Human information processes
aims to provide the designer with a well-structured procedure and support in applying available design techniques.
