Meaning
A formal verification protocol confirms that installed manufacturing equipment performs its intended tasks across all specified operating ranges. Executing operational qualification involves testing alarms, control loops and safety interlocks under simulated load conditions. This procedure succeeds the installation phase but precedes final product testing.
Parameter Verification
Engineers run the system at the lowest and highest limits of its rated performance. They test that temperature, pressure and flow rate remain stable during sudden adjustments. This testing proves that the control systems can handle abnormal situations without failing.
Testing Outcome
The output of this phase is a comprehensive report documenting every run and sensor response. This report must be signed by the validation manager before actual materials are introduced. It provides the legal proof of process capability required by regulators.
Financial Consequence
Skipping these tests to meet a shipping deadline invites disaster during actual production when the machinery runs at full capacity. If a heating element fails to maintain the required temperature under load, the entire batch of product is ruined, leading to immediate scrap and disposal expenses. This waste of raw material and labor forces a complete restart of the validation process, doubling the time to market.
