The document provides guidance on preparing for a pre-approval inspection (PAI) by the FDA. It discusses understanding what to expect from an FDA inspection team, developing an inspection management plan, and preparing the facility and documentation. Key steps include conducting internal audits and mock inspections, training personnel, reviewing documents that will be examined, and designating an inspection team to manage document requests and escort inspectors. The goal is to demonstrate compliance and control over any issues, rather than hiding problems from inspectors.
