ICH Q14 — Analytical Procedure Development
Q14: analytical quality by design — the analytical target profile, method operable design region, robustness, and the method lifecycle that Q2(R2) validation now confirms rather than initiates.
Outline and talking points — the full write-up is still to come. (This one is close to the core of the course — likely deserves depth on par with Q1.)
What this page covers
- The Analytical Target Profile (ATP) — the performance the method must deliver, defined before development.
- Minimal vs. enhanced approaches to method development.
- Method Operable Design Region (MODR) — the analytical analogue of a design space; robustness studied by DOE, not discovered by accident.
- Method lifecycle — development → qualification/validation (Q2(R2)) → continued performance verification → managed change (Q12 established conditions).
- Why Q14 reframes everything in this section: the method is designed against its requirements, and Q2 validation confirms the design rather than testing a method built by guesswork.
- Ties to Q13 — PAT and RTRT methods are developed under exactly this framework.
Lecture prep — open items
- ATP worked example for an impurity method.
- A robustness DOE the class can interpret (main effects + interactions on resolution).
- Decide: is this a full lecture on its own, or paired with Q2?
