Qualification and Validation
Definitions
Glossary
Validation
 Action of proving, in accordance with the principles of GMP,
that any procedure, process, equipment, material, activity or
system actually leads to the expected results
Qualification
 Action of proving that any premises, systems and items of
equipment work correctly and actually lead to the expected
results
(Validation usually incorporates the concept of qualification)

Qualification and Validation
Principle
 Qualification and Validation: Essential part of GMP
 Manufacturer has to identify what qualification and
validation work is required.
4.1, 4.2, 4.8
 Provides proof that critical aspects of work are
controlled and provide documented evidence
 Key elements of qualification and validation defined
and documented: Policy and approach: VMP

Qualification and Validation
Scope
Qualification and validation:
 Applicable to any aspect of operation which may affect the
quality of the product
 Directly or indirectly
 Cover e.g. premises, facilities (utilities), equipment,
processes
4.4
 In case of significant changes – consider the need for requalification or re-validation

Slide 10 of 31
2012
Qualification and Validation
Principle
 Qualification and validation should be done in
accordance with an ongoing programme
 Initial qualification and validation
 Annual review (determine the need for revalidation)
4.5, 4.6
 Ensure continued validation status is maintained
 Policy described in relevant documentation, e.g.
quality manual, or Validation Master Plan

Qualification and Validation
Documentation
 Clearly defines responsibility of performing validation
 Conducted in accordance with predefined, approved
validation protocols
 Recorded results and conclusions presented in
written validation reports – prepared and stored
 Processes and procedures should be established on
the basis of these results
4.7 – 4.10

Qualification and Validation
 A qualification or validation report should reflect the elements of
the protocol, and may contain elements such as:
 Title
 Objective of the study
 Reference to the protocol
 Details of materials, equipment, instruments, personnel
 Programmes and cycles used
 Details of procedure and test methods
… etc.

Slide 18 of 31
2012
Qualification and Validation
 New approaches recommend that manufacturers
should perform a risk assessment as part of their
approach to validation
 Risk assessment can be useful in:
– Identifying the need for qualification, or the extent
and or scope of qualification (e.g. utilities and
equipment)
– areas of focus in process validation
– Cleaning validation

Slide 19 of 31
2012
Qualification and Validation
 There is currently a move to change the approach to
qualification and validation. The principles remain
however the same.
 US and EU guidance now focus on “Process
qualification” which covers the complete lifecycle of a
products with additional focus on product design
 Three Phases are identified that cover “process
design, process qualification” and “continued process
verification”
