In data quality improvement you always have to find a balance between the almost impossible, and usually not sensible, vision of achieving zero percent defects and the good old 80-20 rule about aiming at the 80% most frequent issues and leaving the 20% not so frequent issues to a random fate.
One of the issues that usually falls into the 20% neglected issues is cross border challenges with contact master data.
In a recent blog post on the Postcode Anywhere blog Graham Rhind describes the data quality flaws arising from his relocation from Holland in the Netherlands to Germany. The post is called Validate … intelligently.
Personally I have had a lot of similar issues when moving from Denmark to England in the United Kingdom as for example described in the post Staying in Doggerland.
My guess is that we will see an increasing demand for cross border data quality services not at least as regulators are increasingly looking into cross border issues. The FATCA regulation from the United States tax authorities is an example as described in the post The Taxman: Data Quality’s Best Friend.
As globalization moves forward organizations will increasingly work cross border, people will move between countries and more frequently live in one country and work in another country and buy services in another country. In coping with this reality you can’t keep up with data quality by just using a National Change of Address service and other data quality services focused on and optimized for a single country.
