IQ is an acronym for “Installation Qualification”: which is defined by the FDA as, establishing by objective evidence that all key aspects of the process equipment and ancillary system installation adhere to the manufacturer’s approved specification and that the recommendations of the supplier of the equipment are suitably considered.
The Installation Qualification (IQ) execution; verifies that the equipment, and its ancillary systems or sub-systems have been installed in accordance with installation drawings and or specifications. It further details a list of all the cGMP requirements that are applicable to this particular installation qualification. These requirements must all be satisfied before the IQ can be completed and the qualification process is allowed to progress to the execution of the (OQ).
Conformance with continued Good Manufacturing Procedures. (cGMP's)
requires, that what ever approach is used, it is fully documented in
Validation (Master) Plan
(VMP or VP).
The IQ should not start with the Factory Acceptance Testing (FAT) or
Commissioning tasks, but it should start before these tasks are
completed; enabling the validation team to witness and document the
final FAT and commissioning testing. The integration of these
activities greatly reduces the costly and time consuming replication of
There is a
grey area of testing / inspection in the transition from the IQ to the
Qualification (OQ) that is open to rationalization, i.e. it has to be
done, but it can satisfactorily be included in either the IQ
or OQ. On most projects the simpler the IQ is
kept, the quicker it is completed,
reviewed and out of the way, allowing progress to the OQ. It can
therefore pay dividends to keep the IQ
as basic as possible. Where possible, the IQ can be kept to the
pre-powering up stage. Keeping the
this level allows healthy project progress. There should be no
powering up or utility problems to hinder IQ sign off, and rapid
progress through the OQ to the Performance
Qualification (P1Q) and where applicable the Process Qualification
becomes feasible. It can be reasoned that as soon as you power up, you
enter the equipment operation stage, where verification of the User
Requirements Specification (URS) and 21
CFR Part 11 verification testing are undertaken.
For this reason we have modulized the IQ and OQ, building in the tests and inspections that are not in this grey area, and building the one's that are, as modules that can be added to either the IQ or the OQ. This has not been done just because it might work, this has been advocated by us for some time. We have experience major delays to projects, caused purely by waiting for the client to complete document reviews and approvals. See Comment 9 in cGMP-FDA-483.
The scope of the IQ testing/inspections will cover the under listed subjects, but is not restricted to them alone.
