Yes, if we accept that more is better.  But a high index is more likely if 
one or two attribute scores are great while the others are small.  (Satisfy 
yourself of this by considering just two dimensions.)  So a "bad" product 
may be one which has inconsistent levels of attributes.  I guess we'd really 
have to know what the attributes were, and how they were supposed to go 
together.  Still it sounds like an interesting technique for snowing 
clients, helping them believe we can do magic, and helping them see what 
they want to see.  ... SIGH.
