What Are the Requirements of 21 CFR Part 11?

In pharmaceutical and medical-device operations, computerized-system compliance is not just an audit checkbox; it is foundational to patient safety, product quality, and trustworthy data-driven decisions. FDA 21 CFR Part 11 together with EU GMP Annex 11 provides a practical framework for electronic records and electronic signatures.

1) Risk-Based Computerized System Validation

Each GxP computerized system should be validated according to intended use and risk. URS, design specifications, IQ/OQ/PQ, and lifecycle maintenance should demonstrate data reliability and reproducibility.

2) Veri Bütünlüğü Based on ALCOA+

Records should be Attributable, Legible, Contemporaneous, Original, and Accurate, and also Complete, Consistent, Enduring, and Available.

3) Secure, Tamper-Evident, Reviewable Denetim İzi

Create/edit/delete activities should be automatically logged with user identity, timestamp, reason for change, and before/after values.

4) Access Control, Authentication, and Role Segregation

Core expectations include unique user IDs, least-privilege access, role-based permissions, and prevention of shared accounts.

5) Electronic Signature Compliance

Electronic signatures should be permanently linked to their records, including signer identity, signing time, and signature meaning.

6) Backup, Archiving, and Disaster Recovery

GxP data should be protected through tested backups, long-term retention, and verified restore capability.

7) Change Control, Deviation Handling, and Periodic Review

Software and infrastructure changes should follow formal GxP impact assessment, approval, and traceable documentation.

Practical Conclusion

To implement these requirements sustainably, organizations need an integrated platform with audit trail, role-based access, electronic signature, trusted reporting, and lifecycle validation support. GitoTek Ecosystem software is designed to support these compliance expectations in real GxP environments.
