Regulators Raise Concerns Over Widespread Documentation Gaps in Manufacturing Quality Systems

Regulators and industry bodies have raised fresh concerns over the quality of manufacturing documentation after a series of audits identified recurring gaps in record-keeping, traceability and change control across multiple business sectors.

The findings, drawn from inspections in aerospace, automotive, medical devices and general manufacturing, suggest that documentation failures remain one of the most common weaknesses in quality management systems.

According to a joint briefing issued by European and UK regulatory authorities, inspectors are increasingly encountering incomplete production records, inconsistent revision control and insufficient evidence to demonstrate that changes to processes or materials have been formally approved.

In several cases, companies were found to be operating with outdated work instructions or relying on informal “tribal knowledge” rather than controlled procedures.

“Documentation is not paperwork for paperwork’s sake,” said Claire Donnelly, a senior quality auditor with experience across regulated manufacturing sectors. “When records are incomplete or inconsistent, organisations lose the ability to prove that products were made correctly, safely and in line with customer requirements. That creates risk - not just regulatory risk, but commercial risk.”

The issue has become more prominent as businesses adapt to labour shortages, increased automation and more complex global supply chains. Auditors report that rapid onboarding of new staff, combined with pressure to maintain output, has led some organisations to bypass formal document updates or defer validation activities. Over time, this has resulted in quality systems that no longer reflect how work is actually being carried out.

Industry groups say supplier documentation is a particular area of concern. Several manufacturers told inspectors that they were receiving incomplete certificates, inconsistent inspection data or poorly defined specifications from upstream suppliers.

In some cases, quality teams were compensating by carrying out additional internal checks, masking underlying weaknesses in supplier quality assurance.

A spokesperson for the Chartered Quality Institute said the findings reflect a broader challenge facing businesses. “Quality management systems depend on accurate, current information. When documentation lags behind operational reality, organisations lose control. What we are seeing is not a lack of intent, but a lack of discipline in maintaining quality fundamentals.”

The commercial consequences can be significant. Poor documentation has been linked to delayed customer approvals, failed audits, increased rework and, in some cases, contractual disputes where organisations could not demonstrate compliance with agreed requirements. In highly regulated industries, documentation failures can also trigger enforcement action or restrictions on product release.

In response, regulators are urging businesses to revisit how quality documentation is managed, reviewed and embedded into daily operations. Several audit bodies have indicated that future inspections will place greater emphasis on how organisations maintain document accuracy during periods of change, rather than simply checking whether procedures exist.

As businesses continue to face pressure to deliver faster and more efficiently, quality professionals warn that foundational controls must not be overlooked. “Strong quality systems are built on evidence,” Donnelly added. “If organisations can’t demonstrate what they did, when they did it and why, then quality is already compromised.”
