Usability Testing

There is simply no substitute for putting your designs-in-progress in front of real users to see if they can perform tasks. Usability testing is a well-established method for gathering this feedback in a structured way to drive design decisions. For medical devices, usability validation testing is required for regulatory approval, and must be conducted according to strict guidelines.

We have conducted hundreds of usability tests of everything from automobile navigation systems to financial websites to surgical devices. Beth is co-author of Moderating Usability Tests: Principles and Practices for Interacting with Joseph Dumas (Elsevier, 2008).

Result: Data-driven design decisions; improved user experience, safety, and competitive advantage
