Computerized System Validation (CSV)

Computerized System Validation (CSV) is the process of ensuring that a computerized system used in a GxP environment performs accurately, consistently, and reliably according to its intended purpose.

Reference: FDA — General Principles of Software Validation (GPSV)

CSV ensures that systems support product quality, patient safety, and data integrity, and that all electronic records and signatures comply with regulations.

Reference: FDA 21 CFR Part 11

The main goal is to provide documented evidence that the system works as intended throughout its entire lifecycle — from planning and specifications to testing, deployment, and retirement.

Reference: GAMP 5 — A Risk-Based Approach to Compliant GxP Computerized Systems

CSV is required for systems used in manufacturing, laboratories, quality management, BMS/BAS, and any digital tool impacting GxP decision-making.

Reference: EMA — EU Annex 11: Computerized Systems

Regulatory Background

What is FDA 21 CFR Part 11?

Part 11 defines the requirements for using electronic records and electronic signatures in FDA-regulated environments.
It ensures that any electronic data used in GxP decision-making is trustworthy, reliable, and equivalent to paper records.

Key technical expectations include:

Unique user accounts (no shared logins)

What is FDA 21 CFR Part 11?

Part 11 defines the requirements for using electronic records and electronic signatures in FDA-regulated environments.
It ensures that any electronic data used in GxP decision-making is trustworthy, reliable, and equivalent to paper records.

Key technical expectations include:

Unique user accounts (no shared logins)
Secure audit trails capturing who, what, when
System access control & role management
Electronic signatures linked to the record
System validation to ensure accuracy & reliability.

Reference: FDA 21 CFR Part 11 — Electronic Records; Electronic Signatures.

What is EU Annex 11?

Annex 11 is the European guideline for Computerized Systems used in GxP processes.
It focuses on ensuring the system is fit for intended use, properly validated, and controlled throughout its lifecycle.

Key requirements include:

Validation & documentation
Risk management
Data integrity & audit trails
Backup, recovery, and business continuity
Periodic review of the system
Change control for any software modification

Reference: EU Guidelines for GMP — Annex 11: Computerised Systems.

How are Part 11 and Annex 11 different?

Area Part 11 Annex 11

Scope: Focused on electronic records & signatures Broader: full computerized system lifecycle.
Type: Regulation (mandatory) Guideline (but enforced during inspections).
Audit Trail: Required only when electronic records replace paper Required for all critical GxP data.
Periodic Review: Not explicit Explicitly required
Risk Management: Indirect Mandatory and central.
