Regulatory Advice

Medical device manufacturers often need expert guidance on designing and scoping a human factors/usability engineering (HF/UE) program for a device or system. We have extensive experience helping clients implement usability engineering programs that meet the requirements of IEC 62366-1 and the U.S. FDA. Considerations include whether it is a new or legacy device, the device class (I, II, or II), known use errors, and level of risk. 

Result: A properly scoped HF/UE effort for a given program; avoiding costly delays due to inadequate HF/UE submissions.
