This article is based on the experiences gained through a large data migration and business process outsourcing project in 2019. Examining static data linked to approximately 12 million customer records spread across over 10 source systems led to the early identification of unclean data in approximately 10 percent of the golden source data and resulted in large-scale data remediation efforts that were necessary prior to data migration. Key takeaways and lessons learned about data quality on a financial institution’s customer data are summarized here for the data practitioner, with an emphasis on applicable methods and techniques applied to gain transparency about an institution’s overall current state of data.
