Quality Assurance
Quality gates positioned across critical operating stages—before processing, during controlled activity, at batch release and through corrective-action closure.
System at a Glance
The control logic in sequence.
Quality assurance is a sequence of evidence-based gates, not a single end-point inspection. Each gate can allow progression, impose a hold or trigger corrective action.
- 01
Input Gate
Confirm requirement, source, identity and readiness evidence before processing.
- 02
Process Gate
Review controlled activity, segregation, conditions and exceptions.
- 03
Release Gate
Reconcile specification, product, batch and required documents.
- 04
Closure Gate
Record correction, disposition, authorization and retained evidence.
