Overview of FMEA, FMECA, FTA, HACCP, HAZOP, risk ranking and other tools that can support pharmaceutical cross-contamination QRM.
ICH Q9(R1) provides examples of risk-management tools but does not require one universal method for every problem. The method should fit the complexity, available knowledge and decision being made.
FMEA and FMECA
Useful for structured analysis of failure modes, causes and consequences.
FTA and HAZOP
Can support deeper analysis of causal pathways and process deviations.
HACCP and preliminary hazard analysis
Useful for identifying hazards, critical points and preventive controls.
Risk ranking and filtering
Can prioritize products, processes or scenarios, but scoring should be scientifically defined and documented.
Simple tools can be appropriate
Flowcharts, checklists and facilitated discussions may be sufficient for well-understood low-complexity decisions.
Frequently asked questions
Does ICH Q9 require FMEA?
No.
Can scoring introduce bias?
Yes. Scales and weights should be defined carefully and used with expert judgment.
Should the same tool be used for every plant?
Not necessarily.
Can simple tools be compliant?
Yes, when proportionate to the problem and adequately documented.
