Determining When and How to Include Multiple Users in Human Factors Testing: Case Study Examples.

We wanted to say thank you to everyone who came out and chatted with us about our poster at the 2024 International Symposium on Human Factors and Ergonomics in Health Care in Chicago, Illinois, in March 2024. It was a blast and so great to see our topic found such interest and resonated with so many! It was just so lovely to have all these amazing conversations with all of you human factors and ergonomics nerds about how and when to use multiple users in human factors testing!

Thank you to the authors Heidi Mehrzad, Janet Creaser, Ph.D. and Sami Durrani for emphasizing the need for employing multiple users to ensure realistic simulated-use conditions are provided during human factors testing! 

Because of the overwhelming response following the conference, we decided to publish our poster here for everyone to access and read.


The poster aims to provide examples of #UsabilityTesting for products in which one or more individuals, such as a #Parent, #Caregiver or #Surgical team, may be involved regularly or infrequently in managing a #MedicalDevice or #DrugDeliverySystem for its #IntendedUse and answer questions such as: how to evaluate a device when more than one #IntendedUser may be involved in the use at the same time or in sequence, how to make appropriate decisions about user group inclusion throughout the #HumanFactorsEngineering process, and how to address known or #Foreseeable #UseError scenarios when those scenarios predict that the presence of other users could impact #Safe and #Effective use, and many, many, more.

Each case study walks the reader through the considerations of the intended user group or groups, the #UseEnvironment, discusses the impact the different testing options would yield in relation to performance objectives, and walks through the resolution of how each choice meets #Regulatory requirements for #FDA and #ISO62336 human factors guidance.

Enjoy reading our poster and of course please feel free to reach out to us should you have any further questions regarding human factors testing with multiple users or for that matter all things #HumanFactors in #MedicalDevice and #CombinationProduct development.

We are looking forward to hearing from all of you!
