Data Quality Scorecard and KPI's???

Why not? Information of good quality is an important asset with a high price tag. It takes carefully managed business processes do produce them, so you need management attention and management tools.
That sound very familiar to business people. Scorecard and Key Performance Indicators (KPI's).
So, just to get you going, I have developed this litte sandbox strategy map to information quality:


As for KPI's, here are some suggestions, also to get you started.
Always start at the business impact side and make your priorities correspondingly. Focus on what is really high risks / potential showstoppers / cost generators and so on. You know best.
You can define key performance indicators on 2 levels:
The business object level (the entities or tables in your databases), and / or
The attribute level, eg. Product Group.
If you do it on the higher level, you will probably want to define KPI's something like this: Customer Data Quality Indicator = Number of customer records that contain no missing or incorrect data / the total number of customer records.
However, on the attribute level, you can go down to the most detailed level across all the dimensions like accuracy, completeness, consistency, correctness, integrity, timeliness and uniqueness. You might also consider weighting different measures together to produce higher level indicators.
However, the usual rules of scorecarding apply, so stick with a reasonable number of KPI's. Those that matter most to our business.
Data Quality is an important contributor to what I call Information-driven Business Analysis.
