This domain defines the lifecycle-based approach used to establish and maintain assurance that manufacturing processes consistently produce product meeting predefined quality attributes. It integrates scientific process understanding, risk-based decision making, statistical evaluation, and ongoing performance monitoring. Emphasis is placed on linking development knowledge to commercial control and maintaining a validated state through data-driven lifecycle management.
1. Introduction Lifecycle management within Continued Process Verification ensures that process performance is not only maintained but actively controlled as conditions evolve. It defines how monitoring results are translated into actions that preserve the validated state. This includes structured change…
1. Introduction Signal detection within Continued Process Verification identifies conditions indicating potential or actual loss of process control. It converts monitored data into actionable information by distinguishing normal variation from meaningful change. This section defines how statistical signals are identified,…
1. Introduction Continued Process Verification is the mechanism by which process performance is monitored during routine manufacturing to ensure the process remains in a state of control. It converts process knowledge and control strategy into ongoing, data-driven verification. This stage…
