In the high stakes world of medical devices & biopharmaceuticals, there’s one phase of Compliance that quietly determines your product’s fate: Operational Qualifications (OQ).
Overlook it, rush it, or get it wrong – and the consequences can be detrimental to your (on time) product release.
Where does Operational Qualification (OQ) fit in?
Let’s break this down by sequence; here are three activities which are crucial for ensuring product quality, regulatory compliance and patient safety in regulated industries:
- IQ – Installation Qualification (ensure everything is installed correctly)
- OQ – Operational Qualification (ensure it operates as intended)
- PQ – Performance Qualification (ensure it performs consistently)
While an Installation Qualification focuses on ensuring that the equipment is installed correctly and the 
Performance Qualification ensures that the product can be produced consistently, the Operational Qualification, (OQ), verifies that the installed equipment or system operates correctly and within the operational limits specific to your product. It involves conducting a series of tests to verify that all functions perform as intended, identifying critical parameters, and establishing operating ranges.
The goal is to demonstrate that the equipment or system can operate consistently within its intended design parameters, while meeting your product requirements.
How Important is the OQ Phase?
OQ is crucial for confirming that the equipment needed for producing a product and or system consistently performs, per requirements, over time.
For example, an OQ for a pouch sealer would include evaluating various equipment parameters all while verifying that those parameters ultimately yield a pouch seal meeting the required peel strength opening force. In this case, a multifactorial evaluation of sealing temperatures, sealing dwell time and sealing pressures would be evaluated. This is called a multifactorial qualification and can become even more complicated as the number of equipment setting variables increases.
Why all the fuss – what risks do we need to be worried about?
It depends; how much risk can your career endure? 😉
If it’s a trivial or low-level deviation, the end result may be a fairly minimal impact felt by the OEM.
However, it could be much, much worse.
When FDA regulations are not fully complied with, (or skipped), the downstream implications can be pretty disastrous. If patients are harmed, or medical personnel are put at risk of injury, then it starts to become prosecutable. 
And if the FDA has to work at getting the manufacturer’s attention (to reduce the risks) then the negative consequences for the product maker can become insurmountable.
For example: Some of the key risks and items that should always be considered are as follows.
⚠️ 1. Regulatory Noncompliance
- FDA 483 observations or Warning Letters from regulatory agencies (FDA, EU Notified Bodies) for violating 21 CFR 820.70 or ISO 13485:2016 Clause 6.3/7.5.
- Inadequate validation is one of the top 10 FDA citations year after year.
- Potential product recalls or import bans.
📌 Example: A manufacturer received an FDA warning letter because the sealing equipment on a packaging line was never qualified, leading to undetected seal failures.
⚠️ 2. Product Quality Issues
- Machines may drift out of spec without being detected, producing nonconforming or unsafe medical devices.
- Improper torque, sealing, welding, or dosing parameters can compromise product integrity, sterility, or function.
- Can result in patient injury, product malfunctions, or hospital returns.
⚠️ 3. Production Downtime & Scrap
- Unqualified machines are more prone to breakdowns and inconsistent performance.
- Lack of robust PQ testing can mean excessive scrap rates, rework, and reduced yield.
- Operators and maintenance may struggle due to unverified SOPs or settings.
⚠️ 4. Poor Risk Assessment
- Failure to identify machine-related risks to product safety or quality may lead to regulatory citations.
⚠️ 5. Product Recalls & Liability
If a product defect is traced back to an unqualified machine, the entire lot—or multiple lots—may need to be quarantined or recalled.- Triggers legal risk, liability claims, and loss of customer trust.
- Product liability lawsuits may arise if the failure harmed patients.
~ Here’s one more Expensive Consequence ~
⚠️ 6. Hidden Cost of Requalification
- Retroactive validations are expensive, time-consuming, and often disruptive to operations.
- If you have to revalidate post-market, it can require product traceability reviews, repeat testing, and temporary production halts.
