Process Validation, PPQ & CPV
Process validation is the documented evidence that a manufacturing process consistently delivers a product meeting its predetermined quality attributes. This pillar covers validation master planning, PPQ protocol design and execution readiness, continued process verification in Stage 3, statistical sampling and process capability, and the summary reports that close the lifecycle.

What carries and what breaks when the same validation instinct moves from small molecule tablets through medical devices, RNAi-LNPs, oligonucleotides, autologous cell therapy, gene therapy, and now RNA editing.
- Beginner→Validation Master Planning for a Clinical-Stage Biotech: Getting Started the Right Way
What a Validation Master Plan is for, how to scope it by risk instead of habit, and how to keep it a living document an inspector can actually follow.
- Intermediate→Continued Process Verification: Building a Stage 3 Program That Actually Monitors
How to build a Stage 3 CPV program that catches process drift before it becomes an OOS, covering parameter selection, control charts versus capability indices, escalation rules, and right-sizing for batch volume.
- Advanced→PPQ Readiness: The Prerequisites That Decide Success Before Batch One
What Process Performance Qualification readiness actually requires: the process, analytical, documentation, and CDMO prerequisites that decide whether a PPQ campaign succeeds, checked before batch one starts.
