ICH Q14 - Analytical Procedure Development

What it says

Analytical procedures should be developed using a structured, risk-based approach that defines the analytical target profile, evaluates and selects an appropriate method, and establishes a control strategy for the procedure across its lifecycle, complementing the validation requirements described in ICH Q2(R2).

Paraphrased for plain-language clarity. Always verify against the current published regulation text.

What it means in practice

• ICH Q14 shifts analytical method development from a purely empirical exercise into a documented, risk-based process similar in spirit to how ICH Q8 approaches product development.
• Defining an analytical target profile up front gives a method developer a clear performance target, which then shapes which validation studies in ICH Q2(R2) are most critical to perform.
• A well-documented Q14 development package can support a more flexible post-approval change management pathway for analytical methods, connecting to the change management principles in ICH Q12.

What inspectors look for

• Whether analytical method development records show a structured, risk-based rationale for the chosen method rather than an undocumented selection.
• Whether the analytical target profile and method operable design region, where used, are consistent with how the method is actually being run in routine testing.
• Whether changes made to an analytical procedure after validation are being evaluated and documented consistently with the original development rationale.
