Syringes, Catheters, X-Ray Machines, Medical Software (EMR) - All are considered Medical Devices by all of the notified bodies. But depending upon the specific type, the classification can differ between the various notified bodies, e.g. FDA versus MDR. All medical devices are affected by Human Factors Regulations, some more than others. For example, managing Innovation and meeting the 510(k) Human Factors Usability Requirements can be a daunting task. Product evaluation, product validation, Human Factors Engineering and User Experience testing are all part of the User Centered Participatory Design process. With R&D expenses escalating, it is beneficial to limit and minimize product risk by identifying product designs that may result in serious use errors as early in the process as possible.

HirLan specializes in User Centered Design and the evaluation process associated with innovative ideas, product features, and the final integration of innovation and User Centered Design.

  • Integration of Human Factors into your product lifecycles
  • Application of the General Principles of Human Factors to your future Product lifecycles through User Centered Design concepts
  • Evaluation and Validation of your products against general Human Factors Principles
  • Manage the Risk Error with respect to basic human skills and abilities
  • Usability Testing and the appropriate methods to meet the various requirements of different notified bodies, e.g. FDA/MDR, etc.
  • Accessibility and Cross Cultural / Cross National Design concerns
  • User documentation, packaging and instructions for use

Human Factors Testing

HirLan, Global Human Factors Testing Experts

Both the FDA and MDR (CE Mark) require Formative and Summative Human Factors Testing for the approval process. Formative Testing is a smaller scoped test performed at various stages throughout the Product Lifecycle to ensure product development is progressing as desired and catch usability issues early in the process. The successful Summative Test is the final Human Factors Test prior to FDA/CE Mark Approval and product release. The ultimate goal of Human Factors Engineering and all testing is to ensure Safe, Effective and Usable products are introduced to the public.

Formative and Summative Testing enlist the help of all intended users of a product. Were a Summative Test requiring a minimum of 15 participants from each user group, a Formative Test is much more flexible using up to 8 participants from a target user group. The FDA requires all Summative Tests to be performed in the US whereas the CE requires testing in an EU country. Generally, all test participants should not be company employees or associated with the company. Care must be taken when using pediatric and/or geriatric participants as there are ethical considerations. HirLan is experienced in all methods and requirements associated with global Human Factors Testing.
