Re: Epistemologically valid design theory. Some August observations: 1. The locus of affordance of design outcomes is indeterminate in dynamic social systems. 2. Design theory is best treated pragmatically as an open concept to be evaluated for its usefulness and reliability rather than its epistemological validity and justification. 3. Prediction: Theoretical archeologists will uncover design theory nestled around the crossroads of epistemology and axiology.
