Comparison Table
DNV
enterprise_vendorDelivers management system audits and regulated-industry quality assessments that include GMP-aligned audit support.
Evidence-focused GMP audit approach using quality system and data integrity review methods
DNV provides GMP audit support through experienced audit teams operating under a global standards organization model, which fits organizations that need evidence-based compliance verification. Engagements can be scoped for manufacturing sites, contract manufacturers, and critical processes, which helps when the audit scope must match operational risk. Audit work focuses on documented conformity results and evidence tied to corrective-action closure.
DNV’s food-safety and information-security audit catalog coverage signals breadth in structured audit planning, evidence collection, and reporting workflows beyond typical site-only checklists. A practical tradeoff is that the service depth spans multiple assurance domains, which can increase scoping and evidence collection effort when the goal is only a narrow GMP gap statement.
A strong usage situation is a regulated operator needing a formal audit package that maps findings to documented evidence and follow-up expectations, including nonconformity closure. Another fit signal is cross-border certification needs where audit evidence must support independent assessments across multiple locations.
- +Global GMP audit capability across multiple regions and regulatory expectations
- +Structured audit planning with documented focus on evidence and data integrity
- +Strong expertise in supplier and contract manufacturing compliance reviews
- –Audit scope depends heavily on upfront evidence readiness and document quality
- –Large enterprise process can slow scheduling for narrowly defined reviews

How to Choose the Right Gmp Audit
We look for differences in how an audit workflow handles evidence. The biggest separator is whether Audit trail review and batch record review tie findings to the exact records you need, with enough automation to stay consistent across each gmp audit.
Evidence linking to audit findings
Why it matters
Evidence linking to audit findings matters because gmp audit work fails when notes can’t be traced back to the exact documents and dates. When evidence is linked, teams can defend what they saw and why it led to a conclusion.
How to check
During a demo, ask to create a sample finding and click through to the linked evidence. Check that each link shows record name, version/date (if available), and who recorded or approved it.
Audit log and audit trail review
Why it matters
Audit log and audit trail review matters because gmp audit reviewers expect you to show system activity, not just final states. Strong audit trail review reduces time spent hunting for who changed what and when.
How to check
Ask the tool to show a timeline of a few actions (create, edit, export) and the user identity used in those actions. Then verify the export you’d hand over includes the relevant events in order.
Batch record review workflow
Why it matters
Batch record review workflow matters because gmp audit evidence often hinges on complete, readable batch documentation. A clear workflow helps teams review consistently and avoid missing sections or outdated versions.
How to check
Provide a sample batch record set and ask the reviewer to mark a gap and attach supporting notes. Confirm you can filter by batch, product, and status, and that marked items can be exported as an audit-ready package.
Deviation handling through CAPA linkage
Why it matters
Deviation handling through CAPA linkage matters because gmp audit outcomes often depend on what you did after an issue. Good linkage shows the chain from deviation to corrective and preventive actions and follow-up evidence.
How to check
Walk through a mock deviation, then create a corrective action and preventive action tied to it. Check that the tool records due dates, owners, status changes, and closure evidence.
Change control traceability
Why it matters
Change control traceability matters because audit reviewers look for how changes were evaluated and approved before release. Traceability prevents “orphan” changes that explain nothing during a gmp audit.
How to check
During demo, start with a change request and open the linked impact items. Verify you can show approval steps, linked documents, and which batch records or documents were affected.
Roles and governance for audit work
Why it matters
Roles and governance for audit work matters because audit evidence must be produced under controlled permissions. When access is constrained and actions are logged, the audit trail stays credible.
How to check
Ask for an admin-less reviewer role and try marking findings and adding evidence. Confirm the permissions restrict what that role can change, and that all actions still write to an audit log.
Red flags
- Findings don’t lead you to the exact evidence you need
- Audit trail timelines are incomplete or don’t include user actions
- Batch record review works, but exports miss key context or versions
Fit by situation
- If your gmp audit depends on reviewing many batch record sets, prioritize batch record review workflow.
- If you expect questions about who changed what in the system, prioritize audit log and audit trail review.
- If your audit findings often require follow-through on deviations, prioritize deviation handling through CAPA linkage.
