• Utilities qualification 
• Computerized systems 
• Process validation 
• Cleaning validation 
• Packaging validation 
• Analytical methods 
• Continued process verification 
• Change control 
• Deviation management 
• CAPA 
• Periodic review 
• Requalification 
• Validation documentation 
• Inspection readiness 

Understanding the Revised PIC/S Guide

The revised PIC/S guidance provides general principles for qualification and validation studies in pharmaceutical manufacturing.

Its primary objectives are to:

• Support medicinal product quality assurance 
• Promote GMP-compliant validation programs 
• Improve consistency of validation approaches 
• Support regulatory inspections 
• Strengthen lifecycle management
• Encourage risk-based qualification and validation 

The guidance applies to pharmaceutical manufacturing environments where qualification and validation activities are required to demonstrate controlled and reproducible operations.

Effective Date and Superseded Guidance

The revised guidelines will take effect on:

1 October 2026

It replaces the previous PIC/S qualification and validation guideline implemented in September 2007.

It also supersedes four PIC/S documents covering:

• Validation Master Plan 
• Installation and Operational Qualification 
• Non-Sterile Process Validation 
• Cleaning Validation 

Manufacturers should therefore assess existing validation procedures against the revised framework before the effective date.

Validation Master Plan

A strong Validation Master Plan (VMP) provides the overall structure for qualification and validation activities.

It should establish:

• Validation policy 
• Scope 
• Responsibilities 
• Validation strategy 
• Facility and equipment inventory 
• Qualification approach 
• Process validation strategy 
• Cleaning validation 
• Computerized system validation 
• Documentation requirements 
• Change control 
• Requalification 
• Validation schedule 

The VMP should remain aligned with the pharmaceutical site's quality system and manufacturing activities.

Qualification of Facilities and Equipment

Qualification provides documented evidence that facilities, equipment, utilities, and systems are appropriately designed, installed, operated, and capable of performing as intended.

Typical stages include:

1. Design Qualification (DQ)

Confirms that the proposed design meets defined user and GMP requirements.

2. Installation Qualification (IQ)

Confirms that equipment and systems have been installed according to approved specifications.

3. Operational Qualification (OQ)

Demonstrates that systems operate correctly across defined operating ranges.

4. Performance Qualification (PQ)

Demonstrates that equipment or systems consistently perform effectively under routine operating conditions.

5. Process Validation

Process validation demonstrates that manufacturing processes can consistently produce products meeting predetermined quality requirements.

Manufacturers should consider:

• Process parameters 
• Critical Quality Attributes (CQAs) 
• Critical Process Parameters (CPPs) 
• Manufacturing equipment 
• Raw materials 
• In-process controls 
• Sampling plans 
• Acceptance criteria 
• Batch consistency 
• Continued monitoring 

Process validation should be connected to the overall pharmaceutical quality system.

Cleaning Validation

Cleaning validation is essential for preventing:

• Cross-contamination 
• Product carryover 
• Microbial contamination 
• Cleaning-agent residues 
• Product-quality risks 

Companies should establish scientifically justified:

• Cleaning procedures 
• Sampling methods 
• Acceptance limits 
• Worst-case scenarios 
• Recovery studies 
• Analytical methods 
• Validation protocols 
• Validation reports 
• Ongoing monitoring 

The revised PIC/S framework brings cleaning validation within the broader qualification and validation approach.

Risk-Based Validation

Risk management should be incorporated throughout the validation lifecycle.

Companies should assess:

• Patient risk 
• Product risk 
• Process risk 
• Equipment risk 
• Contamination risk 
• Data-integrity risk 
• System complexity 
• Failure modes 
• Criticality of systems 

Higher-risk processes and systems may require greater validation depth and monitoring.

Computerized Systems and Data Integrity

Modern pharmaceutical manufacturing relies heavily on computerized systems.
