This is a podcast episode titled, Design Validation vs. Human Factors Validation. The summary for this episode is: Human factors and risk create a lot of confusion in the medical device industry. What do you need to do from a design control perspective? Today’s guest is Mary Beth Privitera, principal - human factors at HS Design and AAMI Human Engineering Committee co-chair. She describes the similarities and differences between human factors vs. design validation. Some of the highlights of the show include: ● What constitutes human factors validation? It involves an international standard and FDA guidance on rules that medical device professionals need to follow. ● Design validation focuses more on what’s expected during the audit of a human factors file, if you have a product that is a high risk for harm or injury. ● Most companies don’t know how to intertwine human factors within design and development practices. Use common sense to make a good product design. ● FDA helps developers understand what they need to do and document early on during the design process to avoid validation issues with a product later on. ● Past sales criteria is a major difference between design and human factors validation because it’s difficult to define and measure ease of use. ● Understand all elements that could impact a product’s design. Study your users and use environment before identifying and fixing design issues. ● A task analysis identifies each step users need to take and serves as evidence that you considered their needs and made necessary compromises. ● Mary Beth busts myths related to human factors and design validation, such as needing three people to evaluate and provide feedback on your product’s design.
