Formative Evaluation for Medical Devices

Formative Evaluation is an early-phase Human Factors Usability Testing approach used to understand how users interact with a medical device or healthcare application while it is still under development. Instead of waiting until the design is nearly finished, formative testing brings real clinicians, technicians, and patients into the process to observe how they interpret instructions, navigate workflows, and operate the user interface. This allows teams to detect misunderstandings, task failures, and workflow inefficiencies long before they become costly or difficult to correct.

As part of an IEC 62366-1–compliant Usability Engineering process, Formative Evaluation supplies essential insights for refining the design of your medical device. It enables improvements in information architecture, interaction flows, and overall UX/UI quality, ensuring the product aligns with real clinical environments and user expectations. This reduces use-related risks and strengthens the Human Factors foundation necessary for later validation.

Both healthcare professionals and patients benefit from our in-house Human Factors expertise. With extensive experience in testing medical devices across all stages of development, we are specialists in identifying usability weaknesses early, whether they relate to workflow design, interface clarity, or risk-critical tasks. Our external perspective helps teams overcome internal “tunnel vision” or development-related blind spots that often arise after long design cycles in MedTech. By offering an impartial, expert-driven view, we ensure that usability gaps are recognized and resolved efficiently.
