A lot of teams write the usability engineering file at the end of the project, once the design is already finished. That's when the gaps show up: critical tasks that were never tested, hazard-related scenarios that don't match the risk analysis, and instructions for use that nobody checked with real users. We read the file you already have, clause by clause, and give you a ranked list of what to fix before a notified body or the FDA asks about it.
Who it’s for
- Medical device and diagnostics teams preparing a submission
- Software as a medical device (SaMD) teams with a usability file in progress

Don't have a usability engineering file yet? Building the process and the file is a larger engagement, and we scope and price it separately.
