On receiving the inspection report, the addressee is given four weeks in which to propose measures to address the findings of the inspection.
This document, called a corrective and preventive action, or CAPA, plan, must distinguish corrective action (action intended to resolve shortcomings identified during the inspection) from preventive action (action intended to prevent a recurrence of shortcomings identified during the inspection).
Furthermore, it must be apparent that the proposed preventive action is intended to address the root cause of the shortcoming in question.
