Computer System Validations

Computer System Validation (CSV) is a structured, regulatory-driven process that ensures software, hardware, instruments, and computerized systems used in GxP environments consistently perform according to their intended use and comply with global regulatory guidelines such as:

  21 CFR Part 11
  EU Annex 11
  GAMP 5
  WHO / MHRA
  Data Integrity ALCOA+ Principles
  GXP Assessment
  Risk based Approach

A. Validation Planning

  User Requirements and Process Understanding
  System Categorization (GAMP 5 Category)
  Validation Strategy and Risk Assessment
  Validation Plan (VP) preparation
  Resource, timeline, and responsibility allocation

B. Requirement Definition & Documentation

  User Requirement Specification (URS)
  Functional Specification (FS)
  Design Specification (DS)
  Traceability Matrix (initial creation)
  Data, workflow and regulatory impact analysis

C. Risk Assessment

  System & functional risk assessment (FRA)
  Identification of GxP impact functions
  Identifying critical data points and workflows
  Defining mitigation & control measures

D. Validation Testing

a. Installation Qualification (IQ)

  Hardware installation checks
  Software installation verification
  Server configuration, OS hardening & patch validation
  Backup, user access, and antivirus validation

b. Operational Qualification (OQ)

  Functional verification against FS/DS
  Negative & positive scenario testing
  Security role testing
  Audit trail, electronic signatures testing
  Data integrity testing
  Exception handling verification

c. Performance Qualification (PQ)

  End-to-end real-time business process testing
  Workflow validation with actual users
  System performance, load, and stress tests
  Data migration and integrity checks

E. Data Integrity Validation

  Audit trail review
  Access control validation
  Backup & archival process validation
  Raw data protection
  ALCOA+ compliance checks
  Log review procedure definition

F. Infrastructure Qualification

  IQ/OQ of servers, networks, firewalls
  Qualification of virtual environments
  Backup/restore testing
  Disaster recovery (DR) simulation
  Environmental controls, stability, uptime monitoring

G. Validation Deliverables

  Validation Plan (VP)
  URS, FS, DS
  Risk Assessment Reports
