  • observational field research, ethnography, and contextual inquiry

  • task, workflow, and use error analyses

  • user experience and (graphic) user interface design

  • information architecture

  • (rapid) prototyping, wireframes, and mock-ups

  • usability testing, (FDA) formative and summative

  • human factors & usability eng. in agile development, i.e. SCRUM

  • human factors & usability eng. for medical devices and combination products 

  • design controls and ( risk management, i.e. ISO 14971

  • FDA, MDD/MDR, IEC 62366, and international usability standards for medical devices

With our dual-market – US and EU, multi-disciplinary background, and our bilingual capabilities – English and German, we can provide insight into tackling the complexities of applying human factors within the medical device research and development process whilst providing a clear regulatory path for FDA submission and CE mark approval.
