This section defines the structured execution of qualification at commercial scale. It requires predefined PPQ protocols that specify the number of qualification batches, rationale for batch selection, and identification of worst-case operating conditions.
1. Purpose and Scope This article defines how deviations observed during PPQ are managed and how overall success of PPQ is determined. Focus: 2. Deviation Handling during PPQ Deviation handling during PPQ defines how unexpected events or results are evaluated…
1. Purpose and Scope This article defines how acceptance criteria and statistical evaluation are established and applied during PPQ to determine whether process performance is acceptable. Focus: 2. Role within PPQ Acceptance criteria define what constitutes success.Statistical evaluation provides the…
1. Purpose and Scope This section defines how Critical Process Parameters (CPPs) and the control strategy are verified using PPQ data to demonstrate that the process operates consistently and produces product meeting predefined quality requirements. The objective is to confirm…
1. Purpose and Scope This article defines how sampling and data collection are designed and executed during PPQ to generate representative, decision-quality data. Focus is on practical implementation, including: 2. Role within PPQ Sampling and data collection operationalize the PPQ…
1. Purpose of Process Performance Qualification (PPQ) Process Qualification is referred to as Process Performance Qualification (PPQ) to emphasize that this stage demonstrates actual process performance under routine manufacturing conditions, not theoretical capability. As defined by the FDA lifecycle approach:…
