The Ministry of Public Finance in Costa Rica, which handles the country's financial policies, discovered that its tax data was riddled with inaccuracies. It urgently needed a data quality program in order to increase revenues, root out fraud and noncompliance, and bolster public confidence in the Ministry and its work.

Challenges

  • Ensure that data is complete, consistent, accurate, and reliable
  • Standardize, cleanse, match, and de-duplicate data from multiple systems
