DHF

Term from Medical Device Manufacturing industry explained for recruiters

DHF (Design History File) is a required collection of documents that shows how a medical device was designed and developed. Think of it as a detailed diary that tracks every decision and step taken while creating a medical product. Companies must maintain DHFs to prove to regulators like the FDA that they followed proper procedures when designing medical devices. This is similar to having a complete recipe book that not only lists ingredients but explains why each ingredient was chosen and how the recipe was developed. Related terms you might see include "Design Controls" or "Product Development Documentation."
