Summative Evaluation – Human Factors Validation Test

You must fulfill these legal requirements when it comes to summative evaluations

In contrast to formative evaluations, summative usability tests must be carried out with the final device at the end of development to objectively demonstrate the safe use of the user interface in the intended environment.

​​​​​​​Manufacturers must test all hazard-related use scenarios, whereby the participation of 10-25 users per user group is recommended. The FDA requires at least 15 participants per group, who must be US residents. Therefore, these evalua­tions should take place in the US. 

​​​​​​​The MDR, IVDR, IEC 62366-1, and FDA all require legible labeling. In parti­cular, safety information must be perceptible and understandable and support safe use.   
Proof that this applies to the instructions for use (IFU), quick reference guide (QRG), and labeling on the device can be provided in readability (comprehension) tests with the intended users.
