Good concept. We have been doing something along these lines with the Swedish governement for the past 15 years: facilitated, non-quantified modelling workshops, empolying general morphological analysis (GMA), to investigate the structure and stakeholder relationships invovled in wicked (policy driven) problems.
We recently published a book on our experiance with this:
“Wicked Problems – Social Messes: Decision support Modelling with Morphological Analysis”. Springer, 2011.
