A German pharmaceutical manufacturer engaged Zamann Pharma Support to strengthen compliance in Equipment Qualification (EQ), specifically around Waters Empower CSV documentation and lifecycle controls.
Initially, the expectation focused on improving URS structure, protocols, and validation lifecycle documentation. However, during the assessment, a far more critical issue emerged.
The calibration and preventive maintenance (PM) system showed severe compliance gaps. For instance, sensors were overdue, critical instruments had not been calibrated for years, and maintenance occurred only after failures.
Moreover, no risk-based justification supported calibration intervals, and out-of-tolerance (OOT) events were often ignored or left undocumented. Most critically, equipment remained in production use despite known calibration failures.
From a GMP standpoint, this situation represented a major compliance risk because calibration and maintenance directly define whether qualification remains valid.
Our team supports the planning, execution, and maintenance of qualification and validation activities, including IQ, OQ, and PQ, to keep GMP-regulated systems compliant and under control.
When equipment is used after a documented calibration failure, batch release becomes scientifically indefensible under GMP. Regulators treat this as a direct loss of control over critical process parameters, meaning all data generated during that period is potentially invalid. As a result, QA cannot justify release without a full retrospective impact assessment, and in many cases, entire batch sets are classified as non-releasable due to compromised measurement integrity.
Because repeated use of non-calibrated or failed instruments demonstrates that lifecycle controls are not functioning in practice. Inspectors interpret this as evidence that the validated state is not being maintained, even if initial IQ/OQ/PQ was completed. This shifts the finding from a simple deviation to a systemic failure in equipment qualification governance, often triggering data integrity classification and extended inspection scope.
When OOT results are not properly investigated, equipment drift remains undetected while being continuously used in production. Over time, this creates a hidden deviation from validated operating conditions. Regulators consider this a breakdown of lifecycle validation because the qualification assumption stable and controlled performance is no longer true. Consequently, the equipment is treated as unqualified retrospectively, and impacted historical data may be challenged.
