Most Data Quality Issues Are Really Control Issues

A delayed close, an unreconciled subledger, a failed control, or a management report that does not tie often points to the same underlying issue: the organization does not have sufficient controls over the data it depends on.

When that happens, the response is usually a cleanup effort.

A team is assembled to review records. Data is corrected. Exceptions are resolved. Reports are rerun. In larger situations, organizations may launch a formal data-quality initiative, create a master data governance workstream, or perform extensive remediation after a conversion or implementation.

Those actions are often necessary.

The problem is that remediation is not the same as control.

If the same issue can occur again next month under the same conditions, the organization has reduced a backlog. It has not reduced the underlying risk.

In our experience, many data-quality findings originate from control gaps that were never recognized as control activities. The organization relied on the data, but nobody formally owned the process that ensured the data remained complete and accurate.

Start with the Questions That Matter

When auditors, controllers, or risk professionals assess data quality, they are usually focused on a few fundamental questions.

• Who can create or modify the master data that drives key business processes?
• How would the organization know if critical data failed to load or an interface was incomplete?
• Which reports are relied upon to support decisions, reconciliations, or controls?
• How is the completeness and accuracy of those reports validated?

These questions are not specific to a particular ERP system, reporting platform, or data warehouse. They have existed for decades because they address the same underlying concern: whether management can trust the information being used to operate the business.

Technology can help answer those questions, but only when completeness and accuracy are defined in business terms rather than technical terms alone.

What Meaningful Data Testing Looks Like

Organizations sometimes begin with dashboards and metrics because they are easy to produce and visually compelling.

A more effective approach is to begin with the underlying population.

Can the organization demonstrate that the data being reported is complete when compared to a source that finance, operations, or compliance already trusts?

Can the organization demonstrate that key attributes are accurate when tested against source documentation?

Can process owners explain the exceptions and their impact?

The objective is not simply finding errors. The objective is determining whether those errors could influence a business decision, a financial conclusion, a control activity, or an audit outcome.

That is what transforms data testing from an operational exercise into a control activity.

Data Analytics and Forensics Start in the Same Place

Organizations sometimes think of audit analytics, forensic reviews, and data-quality assessments as separate disciplines.

In practice, they often start with the same foundational steps:

• Identify the population.
• Define expected outcomes.
• Test for completeness and accuracy.
• Investigate exceptions.

The difference is usually the objective.

A data-quality review is looking for control failures or process weaknesses. A forensic review is looking for evidence related to a specific allegation, concern, or hypothesis.

The underlying discipline remains remarkably similar.

A Practical Approach

Organizations looking to improve data quality should start with the information that matters most to the control environment.

A good first step is to identify:

1. The reports, interfaces, and data sources that key controls rely upon.
2. The individual responsible for ensuring the completeness and accuracy of that information.
3. The recurring tests that verify the information remains reliable over time.

Many organizations reverse that sequence by launching a remediation effort before establishing ongoing monitoring and ownership.

As a result, the same issues eventually return.

The Most Important Lesson

Data problems rarely become audit findings because nobody knew they existed.

They become audit findings because the organization relied on information that was never formally recognized as a control dependency.

Once a report, interface, or dataset influences a financial conclusion, management decision, compliance obligation, or control activity, data quality is no longer simply an operational concern.

It becomes part of the control environment.
