  • Category 4: Configured products, typical for CIP/COP control software requiring customization
  • Category 5: Custom-built systems needing complete validation

  CIP/COP cleaning validation software often falls into Category 4 because it usually entails significant configuration to meet site-specific cleaning protocols and automation logic.

• Supplier Documentation Request: Obtain supplier-provided documentation such as Functional Specifications, Installation Qualification (IQ) guides, and standard test scripts to facilitate validation.
• Define Validation Deliverables: Based on system complexity and supplier input, define necessary validation protocols including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).

Supplier engagement supports effective GMP automation and CSV by leveraging vendor expertise while ensuring thorough regulatory compliance. This step aligns with industry best practices outlined in PIC/S Good Practices for Computerised Systems, promoting risk-based validation and supplier collaboration.

Step 3: Installation Qualification (IQ) of CIP/COP Automation Software

The Installation Qualification phase verifies that the CIP/COP software and associated hardware components have been correctly delivered, installed, and configured in accordance with specifications. The IQ is foundational for establishing a validated state and ensuring automated cleaning validation systems reliably support GMP requirements.

Key Actions:

• Check Physical Installation: Confirm all software components, sensors, and controllers have been installed and connected as per vendor documentation and site standards.
