Early-Stage User Research
Applying HFE early can lower overall development costs and reduce the project timeline by helping to design the right thing and design the thing right!
IFU Design
While mitigating risk by design is the first step of device safety, instructional materials are another way to support the safe and effective use of your device.
Formative/Validation Human Factors Testing
RCI conducts formative testing with the aim of providing you meaningful and practical data around your product in development.
Human factors validation testing (sometimes referred to as summative usability testing) is required by regulatory agencies to prove that your device is safe and effective to use by its intended users in its intended use environment.
Human Factors Documentation
Successful human factors (HF) documentation should tell the story of your product’s development, presented clearly enough for reviewing authorities to quickly grasp the rationale behind design choices.
IRB/Ethics Review
RCI’s IRB is registered with the U.S. Department of Health and Human Services (HHS) to review and monitor plans for biomedical research involving human subjects.

We are happy to consult on the following guidance documents:
• FDA Guidance – Applying Human Factors and Usability Engineering to Medical Devices
• ANSI/AAMI HE75
