Book Description: The IOM is the primary guidance document on FDA inspection policy and procedures for field investigators and inspectors. This extends to all individuals who perform field investigational activities in support of the Agency's public mission. Accordingly, it directs the conduct of all fundamental field investigational activities. Adherence to this manual is paramount to assure quality, consistency, and efficiency in field operations. The specific information in this manual is supplemented, not superseded, by other manuals and field guidance documents. The IOM is recommended reading for all operations regulated by the Food and Drug Administration.
