Jürgen Marke is an Operational Intelligence Analyst with the European Anti-Fraud Office (OLAF), which conducts internal and external investigations into irregular or fraudulent activities concerning the financial interests of the European Union. Tableau is used to help analysts visually identify patterns in fraud, and is often more effective than automated statistical analysis.

The specific examples of fraud Jürgen discusses is the misdeclaration of values or origin for textiles, which is an evasion of ad valorem duties. A scatterplot of commodities versus time helps visually cluster cases that meet certain criteria that imply fraudulent activity. Interestingly, the clusters will often - and suddenly - alternate between neighboring countries, depending on which is known to be enforcing customs regulations at the time. In his office, Jürgen proudly displays a wall-sized plotter printout of the scatterplot across all nations.

My favorite part of the presentation came when Jürgen described a request he heard from Ellie Fields, our Director of Marketing: could you show how this was visualized before Tableau? Jürgen smiled as he showed a blank PowerPoint slide, and remarked "I didn't even try - it would be ridiculous!"


Jergen provided an exceptionally entertaining and useful presentation. I plan to blog about it and discuss potential applications for general business.

This was my favorite presentation outside of the keynotes.
