Permanent TSB

Data quality audit, enhancement and integration of high volumes of legacy data


Permanent tsb is the result of the merger of Irish Permanent and TSB Bank. It is the retail banking  arm of Irish Life & Permanent plc, Ireland’s largest home loan and insurance company.


Permanent tsb wanted to understand fully the relationships it had with its existing customers. Part of this understanding was the identification of all products currently and previously owned by its customers, including the legacy data of the merged entities, Irish Permanent and TSB Bank.


Kainos, one of Ireland’s leading financial services Systems Integrators (SI) was selected to conduct a full customer data audit, first to assess the quality of the available data and to identify the root causes of data quality issues. In approaching its solution Kainos selected Datactics technology to do the following:

  • Conduct data quality audit
  • Devise and implement strategies to address data quality issues
  • Define and implement “de-duping” rules
  • Augment and enhance existing customer data
  • Provide full reporting capability

We’re absolutely convinced we’ve made the right choice in selecting Kainos and Datactics for this project. The Kainos approach and the Datactics technology has given us full control and confidence in our matching rules and we were able to get up and running and see results for the entire data set – not just samples – in a much shorter time than we could have expected from some of the much more expensive alternatives we considered.

- Jo O’Connor, IT Project Manager permanent tsb


Datactics technology was used to perform analysis and matching on more than 3.5 million customer records with more than 7 million accounts.

The benefits to the client were:

  • More focused targeting
  • Effective profiling – enabling the bank to identify high net-worth customers
  • Enhanced communication with customers
  • Maximizing up-selling and cross-selling opportunities
