Introduction
Three basic principles of Quality Assurance:
Quality, safety, effectiveness
Cannot inspect quality into a product
Processes must be under control
© WHO – PSM
Validation
WHO validation definition
The documented act of proving that any
procedure, process, equipment,
material, activity, or system actually
leads to the expected results.

Qualification or validation?
A system must be qualified to operate in a validated process
Qualify a system and/or equipment
Validate a process Qualification versus validation, e.g. you
qualify an autoclave, whereas you validate a sterilization process

Meticulous and careful planning

Validation
Validation Master Plan Recommendation only Cover manufacturer’s validation policy and needs
Provides information on validation
organization
It should describe:
why?
what?
where?
by whom?
how?
when?

Validation
Validation Master Plan
Prospective validation
Concurrent validation
Retrospective validation
Revalidation
Change control
© WHO – PSM
Validation
The VMP helps:
Management
Validation team members
Project leaders
GMP inspectors
© WHO – PSM
Validation
The VMP
Identifies validation items (products, processes, systems)
Defines nature and extent of testing
expected
Outlines test procedures and protocols
Summary document
Management agreement

Validation Activities in VMP
Every validation activity included
Revalidation
Validation of new process cycles
Large validation projects have separate VMPs
Include reasonable unexpected events
Validation
© WHO – PSM
Validation
The VMP:
Enables overview of entire validation
project
Lists items to be validated with the planning schedule as its heart
Is like a map
© WHO – PSM
Validation
The “Introduction” to the VMP Validation policy
Project scope
Location and timing (including priorities)
Validation procedures
Standards
© WHO – PSM
Validation
VMP should state who is responsible for:
Preparing the VMP The protocols and SOPs Validation work Report and document preparation and control Approval/authorisation of validation protocols
and reports in all stages of validation process Tracking system Training needs in support of validation
© WHO – PSM
Validation
VMP should contain: Cross references to documents
Specific process considerations
Specific characteristics briefly outlined
Validation list (What to validate)
premises, systems and equipment processes products
© WHO – PSM
Validation
VMP should contain: Descriptions of
plant (where to validate) processes products
Personnel attributes expertise and training
Key acceptance criteria
© WHO – PSM
VMP should contain: Format for protocols and other
documentation List of relevant SOPs (How) Planning and scheduling (When) Location (Where) Estimate of staffing requirements (Who) A time plan of the project (When) Annexes
Validation

Validation
VMP should contain change control
Policy and procedure
Risk assessment
Authorization
Failure to properly document changes to the
system means invalidation of the process
© WHO – PSM
Validation
Changes that require revalidation Software changes; Controllers
Site changes; Operational changes
Change of source of material
Change in the process
Significant equipment change
Production area changes
Support system changes
© WHO – PSM
Validation
In summary, a VMP should contain atleast: Validation policy Organizational structure Summary of facilities, systems, equipment,
processes to be validated Documentation format for protocols and
reports Planning and scheduling Change control Training requirements
