Today, both the EU Medical Device Directive (MDD) and U.S. Food and Drug Administration (FDA) require that human factors and risks of use errors are accounted for in the development of medical devices. International standards, such as IEC 60601-1 3rd Edition and specifically IEC 60601-1-6, address usability engineering and aim to minimize risks caused by poor usability. In any situation where medical devices are used, there is a responsibility to ensure only well-designed, ergonomic products make it to market. The easier a product is for the user, the safer it is for the patient, and consequently the product can increase its competitiveness in the market place.
Usability Engineering as a Process Cycle
IEC 62366 provides extensive guidance on how to implement usability engineering to minimize risks. The standard defines the following steps for the user interface design cycle within the medical context:
1. Define application and essential performance
2. Define frequently used functions
3. Identify hazards related to usability
4. Define primary operating functions
5. Create usability specification
6. Create usability validation plan
7. Design and implement user interface
8. Verify usability
9. Validate usability

If a user doesn’t need to ask instructions, or develop workarounds to accomplish what he/she intends to do, you are on the right track with your product. If you have, at the same time, crafted an aesthetically pleasant piece of equipment or software, you are about to create a winner.
