at one level, i agree with Clifford Snow's comment that first you need
to define data quality.

at another level, i think that we can talk about the following:

1) consistency in tagging. editor improvements, better documentation, better
     training materials can all help with this

2) improved processes and controls for data import (this is work that is 
     on the US import committee). there are a lot of imports of the past 
that suffer
     from Quality Control issues, and lots of imports that never should 
have been
     done because of problems with the data quality.

3) in the US (and you did ask on talk-us), identifying and dealing with 
the shaky
     Tiger data from the 2007 tiger import. some of this has been done, 
but it's an
     ongoing effort and is one of those things that is easier to say 
than it is to do
