The Definition – What Is IQ, Really?
Installation Qualification (IQ) is a documented verification process that confirms that equipment, systems, and instruments are installed according to approved specifications, drawings, vendor recommendations, and regulatory requirements.
It answers the question: “Has this equipment been installed correctly?”
- Is the equipment placed in the designated area?
- Are the utility connections properly fitted?
- Is every screw, panel, and port compliant with design and safety norms?
- Are manuals, certificates, and drawings available and correct?
The Execution Path – Steps of IQ
The Grand Tale of IQ — Applications Across the Pharmaceutical Kingdom
Once upon a time, in the sprawling kingdom of PharmaLand, the wise elders (Quality Assurance) decreed that nothing could be trusted until it was proven sound from the ground up. Thus was born the ritual of Installation Qualification (IQ) — the first step to building the most trusted empire of medicine.
Every structure, tool, and device in PharmaLand needed an IQ scroll (documentation) to prove its rightful place.
Let’s journey through the different territories where IQ ruled supreme:
Thus, the mighty IQ spread across Pharma land, ensuring every cog, every wire, and every bolt whispered a tale of compliance, precision, and trust.
Visual Representation: The IQ Tree of Validation
Each branch of the IQ Tree nurtures a different aspect of the system, ensuring no weakness, no gaps, and complete traceability — the roots of pharmaceutical confidence.
Types of IQ:
Tools of the Trade – What IQ Comprises
IQ isn’t just a checklist. It’s a comprehensive investigation. Below is a breakdown of its main components:
| Component | Description |
|---|---|
| Equipment Description | Details like make, model, serial number, and function |
| Location Verification | Confirms equipment is installed in the intended space |
| Utility Verification | Power supply, HVAC, compressed air, water, gas, drainage, etc. |
| Part & Component Check | Verifies all mechanical and electrical components are present and correct |
| Documentation Review | SOPs, user manuals, material certifications, calibration certificates |
| Software Installation | For computerized systems, software version and installation validation |
| Safety Features Verification | Emergency stops, interlocks, alarms |
| Instrument Calibration Status | Ensures that all measuring instruments are within calibration |
The Script – IQ Documentation Package
Every IQ must be thoroughly documented and auditable. Here’s what a typical IQ protocol includes:
- Purpose and Scope
- Roles and Responsibilities
- Reference Documents (User Requirement Specifications, Design Specs)
- Equipment List
- Installation Checks and Acceptance Criteria
- Deviation Handling
- Attachments (Certificates, photos, schematics)
- Conclusion and Approval Section
The IQ protocol is approved before execution and closed only after completion of all checks. Deviations, if any, are investigated, justified, and resolved.
The Qualification Continuum – IQ, OQ, PQ
IQ is the first step of the V-Model in pharmaceutical validation. The steps that follow:
| Qualification Stage | Focus Area | Key Question Answered |
|---|---|---|
| IQ (Installation) | Installation according to specification | “Is the equipment installed correctly?” |
| OQ (Operational) | Functional testing of the system | “Does it operate as intended under all conditions?” |
| PQ (Performance) | Real-world performance with process inputs | “Does it perform effectively in routine use?” |
IQ lays the groundwork. Without it, the rest crumbles
IQ in Regulatory Context – What the Authorities Say
Regulatory bodies like the FDA, EMA, and WHO emphasize IQ as a critical GMP requirement. Here’s a quick comparison:
| Agency | Guidance Document | IQ Reference |
|---|---|---|
| FDA | 21 CFR Part 211 & 820, Process Validation Guide | IQ is part of Equipment Qualification |
| EU EMA | EU GMP Annex 15 | IQ must be documented and approved |
| WHO | WHO TRS 961, Annex 6 | Emphasizes verification against manufacturer specs |
Non-compliance with IQ requirements can lead to 483 observations, warning letters, or rejection of the entire validation package.
Challenges in IQ – Pitfalls and Lessons
- Missing Documents: Without manuals or wiring diagrams, verification becomes guesswork.
- Incorrect Installation: Equipment not installed as per design can affect critical process parameters.
- Delayed Qualification: If installation is done but IQ is pending, equipment cannot be used.
- Untrained Staff: Execution must be handled by trained validation and QA professionals.
Why IQ Matters – Beyond Compliance
IQ is not merely a box-ticking exercise. It ensures that:
- Equipment works safely and effectively
- There are no surprises in downstream validation
- The company meets regulatory expectations
- The product quality is preserved from the first moment of use
