Definition
The systematic monitoring of a process after implementation to confirm that it remains stable and continues to meet quality requirements.
Human Explanation
The process is observed during routine use to detect loss of control or capability.
Why it Matters
Changes in materials, equipment or operating conditions can affect process quality over time.
Conceptual Boundary
CPV does not replace initial Process Validation; it continues the evidence during routine operation.
Practical Perspective
CPV uses process data, quality indicators and trend analysis to identify drift and emerging deviations.
