Building trust through data quality tools
ArticleHow to get your data into shape, free up your data scientists and empower confident decision making.

Do your data programmes deliver business objectives, optimise performance and meet regulatory standards? Nikhil Asthana and Kamaldeep Kaur explain how external assurance can help meet these challenges.
The most successful financial services firms have complete command of their data to drive product quality, decision making, customer service, and operational efficiency.
However, information comes with responsibility. Companies must ensure their data programmes meet increasingly stringent regulator expectations.
In addition, a malfunctioning data programme can also cause irreparable damage to customer trust – take a company that sends out incorrect billing information or accidentally shares third-party information.
In short, regular assurance is needed to ensure data frameworks are working hard from a business perspective yet are also reliable, accurate, and secure.
The following high-profile (anonymised) cases are instances in which financial services institutions sought external assurance of data programmes to resolve issues that had already resulted in heavy financial penalties. The fines ran into millions of pounds that could have been avoided had external assurers been involved at an earlier stage.
A review of your data programmes offers valuable insight into various aspects of operations, including data strategy, process design, technology, and governance.
Our Assurance Maturity Framework is a useful tool for validating data programmes. It splits the programme lifecycle into five stages, from requirement management to final reporting.
Each stage is evaluated using three sources of information:
The result is a clear picture of a programme’s strengths and weaknesses, which quickly identifies any necessary remedial action.
Though frameworks such as the above can guide internal teams, an external perspective is a powerful way to identify gaps and weaknesses that might be overlooked.
External assurance specialists can also help with strategy, process design, technology, implementation, and governance while ensuring you're compliant with the latest regulatory changes.
A leading retail and commercial bank in England asked us to conduct a comprehensive review of their payment protection insurance (PPI) data waterfall programme, specifically:
The programme collated data for complaints, commissions, returns, payments, and many more workstreams acquired from means, such as phone calls, emails, and certified management consultant files.
We evaluated the PPI programme using our Assurance Maturity Framework and methodology (questionnaires, artefacts and continual feedback). Our work involved:
Our review identified one high, four medium and three low-risk action points.
We identified major gaps concerning test case traceability and the reconciliation of final output numbers with the data sources.
Additionally, our advice on identifying critical data elements and establishing data validity rules not only ensured report accuracy but also led to improved compliance and performance, enabling a clear assessment and comparison with industry standards.
External data assurance can ensure that your firm has access to up-to-date insights on industry standards and best practice to improve your internal processes and decision-making abilities.
It should provide a robust gap analysis and a clear set of metrics to assess your data and compare it to others in the industry.
Our five-phase agile process ensures continuous engagement for swift risk mitigation.
