Research versus Design Paradigms
positivism
technical rationality
rational problem solving

phenomenology
etc, e.g.
“Vienna Circle”
etc, e.g.
“phase models”
constructionism
design as reflective practice
etc, e.g.
“idealism”
etc, e.g.
“hermeneutic”
Results from both Paradigms
positivism
limits
assessment criteria

constructionism
attractors
design solutions
Comparison of both Paradigms
theories and models
abstracting
reality (t1)
concretisation
reality (t2)
positivism :
constructionism :
{theory, model  reality
{theory, model  reality
reality (t1) = reality (t2)
reality (t1)  reality (t2)

Conclusions
• a coherent and powerful corpus of descriptors
and technical terminology
• a theoretical framework to investigate the
interaction space
• a rigorous validation method to prove the
design relevant knowledge
