How OPUS can improve your human factors analysis

Take the guesswork out of your medical product HFE activities by leveraging our tools that support project scoping, human factors analysis and user interface design.

Our complimentary tools help with key HFE decisions, like defining an appropriate scope for an HFE project or usability test, or choosing the right text size. Our premium tool – the RCA Wizard – enhances your RCA skills by putting hundreds of root causes at your fingertips.

RCA Wizard (Premium) - Root Cause Analysis Tool

The Root Cause Analysis (RCA) Wizard guides you through the RCA process to identify potential root causes for usability test findings. The tool includes our library of hundreds of carefully crafted root cause write-ups, including those for a wide variety of user interfaces (e.g., hardware, software, instructions, training) and product types (e.g., medical devices, combination products, in-vitro diagnostics).
