The Audit Trail Examination Playbook

A Step-by-Step Guide for Examining Electronic Records and Detecting Data-Integrity Risk

Most pharmaceutical professionals understand that audit trails are important. Far fewer have been shown exactly how to examine one.

The Audit Trail Examination Playbook was created to close that gap.

Written by DeVaughn Edwards, a former FDA Investigator and pharmaceutical Quality executive, this practical guide walks the reader through an audit trail examination from beginning to end. It is designed for the overwhelming majority of Quality professionals, auditors, laboratory personnel, consultants, and managers who are expected to evaluate electronic records but were never given meaningful, hands-on instruction.

This is not a technical book written for computer-system experts. It is a field-oriented playbook written for the person sitting in front of a chromatography data system who needs to know what to request, where to begin, what questions to ask, which events require further investigation, and how to determine whether the electronic evidence supports the reported laboratory result.

The playbook explains how to prepare for the examination, define its scope, obtain the correct records, confirm user identities and access levels, reconstruct the sequence of events, evaluate deleted or aborted activities, examine reintegration and reprocessing, assess timestamps and reason entries, and connect the electronic evidence to the underlying GMP record.

Readers are also shown how to distinguish an unusual event from an actual deficiency, conduct effective follow-up questioning, document conclusions, and recognize when an isolated concern may represent a broader data-integrity or quality-system failure.

A fully executed example demonstrates how the examination process works in practice.

This playbook will help you:

• Prepare for and conduct a structured audit trail examination
• Navigate a chromatography data system with greater confidence
• Identify deleted, aborted, repeated, altered, or unexplained activities
• Evaluate manual integrations, reprocessing, and reason-for-change entries
• Reconcile electronic activity with laboratory records and reported results
• Develop defensible conclusions supported by objective evidence

The Audit Trail Examination Playbook is especially valuable for Quality Assurance professionals, internal and supplier auditors, laboratory managers and supervisors, data-integrity investigators, compliance consultants, and personnel preparing for an FDA inspection.

You do not need to be a computer expert to conduct an effective audit trail examination. You need a logical process, the right questions, and an understanding of what the electronic evidence is telling you.

This playbook provides that process.
