Yes, strange question... and perhaps necessary in some contexts. Wether the only way to embrace a complex object of study (e.g. social impacts of a big project of infrastructure) coincide with the "unfaithfull" of a enterprise wich department of r+d only believe in "numbers" and "strict steps"... and perhaps some of "where's your model for a project like the mine?"... Could be a choice to construct "the best possible-model" for this kind of situations? For "legitimating our job?", and at the same time for "introducing a qualitative-methodology-is-reliable" axiom into som rigid and traditional scientific minds?"... Both? Some more?
