What is Installation Qualification (IQ)?
IQ confirms that equipment or a system has been physically delivered, installed and configured exactly as intended, before any testing of how it actually operates begins. This includes verifying utilities, piping, instrumentation and connections match the manufacturer's requirements and the facility's approved design.
IQ typically involves comparing the as-installed equipment against purchase specifications, engineering drawings and the manufacturer's installation manual, documenting that every relevant design feature and connection matches what was intended.
Because IQ is the foundational first stage, any gaps or discrepancies identified here should be resolved before moving on to Operational Qualification, since testing operation on improperly installed equipment would produce unreliable or misleading results.
Why is Installation Qualification (IQ) important?
Confirming correct installation before testing operation reduces the risk of chasing operational problems that are actually rooted in a basic installation error, saving significant time and rework later in the validation process.
IQ documentation provides the foundational evidence auditors and regulators expect, showing that equipment was verified against manufacturer specifications from the very first step, not assumed to be correct.
A thorough IQ also creates a reliable baseline reference, useful later if equipment needs to be reinstalled, relocated, or compared against its original approved configuration.
How does Installation Qualification (IQ) work?
A typical IQ process includes:
- Specification review. Confirm the equipment's design features match purchase specifications.
- Physical verification. Check that the equipment, piping and utilities are installed as designed.
- Documentation review. Confirm manuals, drawings and certificates are complete and available.
- Calibration verification. Confirm any required instrumentation calibration was completed.
- Deviation resolution. Address and document any installation discrepancies found.
- Sign-off. Obtain approval confirming installation is complete before proceeding to OQ.
Installation Qualification (IQ) vs. Operational Qualification (OQ)
| Comparison | IQ | OQ |
|---|---|---|
| Confirms | Correct installation and configuration | Correct operation within defined limits |
| Sequence | First stage | Second stage, follows IQ |
Real-world examples of Installation Qualification (IQ)
A pharmaceutical manufacturer verifies that a new filling machine's utilities, piping and control panel were installed exactly according to the manufacturer's installation manual before any operational testing begins.
A medical device company confirms that a new molding press's electrical connections and safety interlocks match approved engineering drawings during IQ.
A quality engineer documents a discrepancy during IQ, noting that a required calibration certificate for an installed sensor was missing, resolving the gap before moving to OQ.
Regulations and standards related to Installation Qualification (IQ)
IQ is a foundational element of process validation expected under GMP regulations and FDA process validation guidance, applicable across pharmaceuticals, medical devices, biotechnology and other regulated manufacturing sectors.

Common mistakes with Installation Qualification (IQ)
Common mistakes include rushing through IQ to reach operational testing sooner, missing installation discrepancies that later cause confusing or unreliable OQ results.
Other problems include failing to document IQ thoroughly enough to serve as a reliable baseline reference if the equipment is later moved, serviced, or needs re-qualification.
