One of my intellectual hero's is Donald Schön. I have sine the mid 1980s been impressed and inspired by his writings on design. His theoretical framework is broad in scope, deep in detail and ambitious and by most today overlooked. Of course, Schön is one of the most cited design thinkers but his ideas has been reduced and are usually referred to only be about "reflection". Schön's work is much more than that.
Anyway, to those to engage in trying to produce new methods and tools that can support design practice, there is a wonderful quote from Schön that is worth 'reflecting' upon.
(You have to exchange 'policy academics' with 'design academics' in this quote.)
"If policy academics want to build a better understanding of policy practice in a way useful to practitioners as well as appropriately rigorous, then they must not bypass the research in which practitioners are already engaged. If they disregard what practitioners already know or are already trying to discover, they are unlikely either to grasp what is really going on or to succeed in getting practitioners to listen to them." (Schön & Rein, "Frame Reflection", 1994, p.193.)
Way too often we can observe attempt from academia to improve design practice that is not grounded in any serious understanding of practice. What Schön is arguing for is what I have in other places called "rationality resonance", which is a concept that captures the ideal situation when the rationality underlying an 'improver's' suggested change resonates with the 'improved' practitioners own rationality. When this is not in place, the noble attempt to improve design practice ends up either being neglected or destroying the very nature of design practice.
So, go back, read Schön's books. They constitute an extraordinary source of design wisdom.
