Definition

process parameter specification that prescribes a variable which has an impact on a critical quality attribute

Explanatory Notes

FROM ICH: process parameter specification whose variability has an impact on a critical quality attribute and, therefore, should be monitored or controlled to ensure the process obtains the desired quality

Examples

• pH specification for the viral inactivation process, due to its impact on the viral clearance capability of the intermediate; temperature specification for the fermentation process, which affects product titer and impurity levels; agitation speed specification for the cell culture mixing step, where excessive shear stress can impact cell viability and product quality;

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs to have a set of necessary and sufficient conditions. In particular criticality determination is missing as well as a more semantically specific connection to a critical quality attribute specification

Formal Axioms

First-Order Logic Axioms

CriticalProcessParameterSpecification(x) → ProcessParameterSpecification(x) ∧ ∃y (CriticalQualityAttributeSpecification(y) ∧ isAbout(x, y))

Semi-Formal Natural Language Axioms

if x is a ‘critical process parameter specification’ then x is a ‘process parameter specification’ and x ‘is about’ some ‘critical quality attribute specification’
