There is a facility in the heart of Silicon Valley where people are handed medical devices they have never seen before and asked to simply use them. They might be nurses, patients, caregivers, or physicians. Some of them make mistakes or struggle to succeed. Some of those mistakes are alarming. And every single one of them represents a useful learning opportunity.
This is how Anthony D. Andre, PhD, CPE, prefers to learn. Not through assumption, not through the confident opinions of engineers alone, but through careful, methodical observation of real human beings interacting with products that are meant to help them or others. As the Founding Director of Interface Analysis Associates LLC (IAA), a leading healthcare human factors, usability, and ergonomics consulting firm operating since 1993, Dr. Andre has built a career at the intersection of science and empathy, asking the question that too few people in healthcare product development think to ask early enough: What happens when a real human actually uses this?
A Course Description That Changed Everything
The origin of this conviction traces back to a moment of almost accidental discovery. While studying computer science and math at the University of Illinois, Dr. Andre came across a course description in the psychology department that introduced him to the field of human factors.
“After taking my first course on the topic, I was hooked on the discipline, changed my major, and have ever since been devoted to the field of human factors and ergonomics,” he recalls.
It is the kind of conversion story that tends to produce lifelong practitioners. He went on to earn a Bachelor’s, a Master’s, and a PhD in Human Factors/Engineering Psychology from the University of Illinois at Urbana-Champaign and became a Board-Certified Professional Ergonomist (CPE). Before long, he was serving as a Principal Research Scientist at NASA Ames Research Center, conducting research on advanced pilot-vehicle interfaces in the aerospace sector and improve the safety of airport ground operations.
The NASA role was serious, consequential work. However, while working in aerospace research, he increasingly found himself drawn to the application of human factors to all sorts of products, beyond just aviation. And so, in 1993, he established Interface Analysis Associates, determined to take the discipline wherever it was needed most, be it high technology, telephony, computer input devices, websites, business software, automotive interfaces, consumer products, medical devices, and more. Healthcare products such as drug delivery systems and medical technology, over time, became the firm’s primary business focus.
That same year, Dr. Andre joined San Jose State University as an Adjunct Professor of both Psychology and Industrial & Systems Engineering and soon became a founding faculty member of their Human Factors and Ergonomics Graduate Program. The program has since grown into one of the largest of its kind in the United States, a development that reflects both the expansion of the discipline and the quality of instruction Dr. Andre has brought to it across more than three decades of teaching. Along the way, Dr. Andre was recognized as the Outstanding Instructor of the Year by the College of Engineering and has supervised over 80 student theses.
Building the Firm, Shaping the Focus
IAA is, by design, a deliberately small organization. Ten people. All long-term employees. This allows Dr. Andre to be personally involved in every project. That is not a limitation; it is central to how the firm operates and the supreme level of customer service expertise and quality it affords its clients.
“With only 10 people, all long-term employees, there is no ‘bait and switch’ at IAA,” he says plainly. “And there is no ‘B’ team.”
Every year, the firm serves approximately 40 pharmaceutical and medical technology companies, performing design reviews, developing interface and instructional designs, conducting formative studies, validation protocols, use-related risk analyses, comparative non-inferiority studies, and summative validation testing. For over 33 years, IAA has worked with hundreds of organizations across the industry, including Amgen, Bayer, Biogen, Genentech-Roche, GSK, Intuitive Surgical, Johnson & Johnson, Medtronic, Merck, Novartis, NovoNordisk, Philips Medical, Sanofi Aventis, Sun Pharma, and Teva Pharmaceutical, alongside scores of emerging biotech firms and startups navigating the FDA approval process for the first time.
The firm operates two state-of-the-art testing facilities in Saratoga, California, in the heart of Silicon Valley, making IAA one of the longest-running independent usability testing laboratories in the San Francisco Bay Area, if not the country. Each facility includes a participant reception area, a testing room, a client observation room, and a dedicated AV and data collection room separated by a one-way mirror, a setup engineered to minimize distraction and produce cleaner, more reliable data.
Beyond testing, IAA’s services extend into interface design, ergonomic evaluations, instructional design, clinical trial human factors support, risk management and regulatory advising.
The Great Misconception
There is a conversation Dr. Andre has more often than he would like. It begins when a client calls with urgency in their voice, explaining that they need a human factors validation study because their FDA submission deadline is approaching. While they’re right to want the study, they’re mistaken about how long they’ve waited and what is needed to succeed in such a study.
“Too often I get contacted only because a sponsor realizes they must perform a validation study to get their FDA approval or clearance,” he explains. “They don’t realize that the biggest value of human factors is in the design phase, making products intuitive, effective, and safe to use from the start.”
The distinction matters enormously. A product evaluated for usability only at the validation stage is a product whose design flaws may already be embedded. Getting human factors thinking into the development process early, during the design phase rather than at the point of validation, is where the most significant improvements occur. It is also, he believes, where the most meaningful work gets done.
“They may not yet fully recognize the value a true human factors journey can bring to their product, company, and end users,” he says.
The Method and the Mission
IAA’s methodology begins with evidence-based principles and established human factors science, but it does not stop there. The firm takes a layered approach in which use-related risks are assessed early and used to shape design decisions, research priorities, and testing protocols. Safety and accuracy come first. Once those risks are addressed, the work turns to the fuller dimensions of user experience: satisfaction, intuitiveness, and a seamless experience that reduces friction for users.
“We optimize which services should be enacted at the right time to better the user experience and to create a safe, effective, and approvable product,” he explains.
Every deliverable is subject to extensive cross-review before it leaves the firm. On a given workday, Dr. Andre begins by assigning work to the team, then moves through client communications, guidance sessions with staff, and quality oversight across all active projects.
The four pillars of expertise he identifies as central to IAA’s work are a deep understanding of user needs, genuine empathy for the end user, rigorous application of human factors principles and science, and authoritative mastery of the FDA approval process.
“I am most passionate about introducing human factors to new clients and helping them integrate the discipline into the development process to create safer, more effective products,” he says.
The moment he finds most professionally satisfying is when a client receives FDA clearance or approval and the product finally reaches the patients and care providers it was designed to help.
The Road Back From Rejection
Some of IAA’s most consequential work arrives under the most difficult circumstances. A Complete Response Letter (CRL) is the FDA’s formal mechanism for rejecting a product application. A CRL can arrive as a devastating blow to a sponsor, particularly for startups and smaller companies whose entire commercial future rests on the approval of a single product.
Dr. Andre and his team have built a specialty out of exactly these situations. IAA’s Human Factors Validation Recovery practice takes on companies that have already received a CRL on human factors grounds, reassesses the full scope of what went wrong, applies IAA’s methodology comprehensively from that point forward, and constructs a revised human factors program strong enough to persuade the FDA to reconsider.
“These projects are both the most challenging and the most rewarding at the same time,” he says.
The work requires every capability IAA brings to standard engagements, deployed under conditions of greater urgency, higher stakes, and with a client who has already experienced a significant setback.
“Our longevity and number of clients served over 33 years” is, he reflects, among his proudest milestones, alongside the history of product approvals that have brought safe, usable devices and drug delivery systems to the patients who need them.
A Discipline Built From the Ground Up
What separates Dr. Andre’s legacy from that of a skilled individual practitioner is the extent to which he has invested in building the structural foundations of the field itself.
In 2012, he founded the International Symposium on Human Factors and Ergonomics in Healthcare, an annual gathering that has since grown into the largest conference of its kind in the world. He has served as one of its chairs since its founding, and the symposium has become the defining venue where the global healthcare human factors community gathers each year to share research, best practices, and emerging knowledge.
In 2020, he founded Human Factors in Healthcare, a peer-reviewed journal published by Elsevier, and serves as its Founding Editor-in-Chief. The journal is rapidly establishing itself as the most widely read and highly regarded publication in the field.
He is also a Past President, Titan, and Fellow of the Human Factors and Ergonomics Society (HFES) and a Fellow of the International Ergonomics Association (IEA). To date, he has authored more than 150 publications and delivered over 500 presentations.
Over the course of his career, Dr. Andre has received numerous honors recognizing his contributions to research, education, professional outreach, product design, and ergonomics practice. His awards include the HFES Arnold M. Small President’s Distinguished Service Award (2019), the HFES Keith Hansen Professional Outreach Award (2018), the Foundation for Professional Ergonomics Ergonomist Practitioner of the Year Award (2016), the HFES Product Design Technical Group User-Centered Design Award (2009), the College of Engineering Lecturer of the Year Award (2009), and the Best Article Award from Ergonomics in Design Journal (2006).
Looking Forward
Dr. Andre sees the field at an inflection point. For most of history, human factors in healthcare have been something companies engage with primarily because regulations require it. He believes that era is closing.
“I think in the near future it will be considered a core discipline that, regardless of regulatory requirements, will be viewed by industry as the key to a successful product,” he says.
In the future he envisions, every pharmaceutical, biotechnology, and medical technology company will employ human factors professionals not as a compliance function, but as a permanent, central part of their research, design, and development teams.
His own role in that future, he hopes, will be exactly what it has been: leading IAA, continuing the symposium, growing the prominence of the journal, and serving as a thought leader and unifying force for the global healthcare human factors community.
Beyond the Laboratory
Away from the firm, conferences, teaching, and regulatory submissions, Dr. Andre lives on a ski mountain in southwest Reno, Nevada. He and his wife of 30 years hike the surrounding terrain, watch the wild horses that roam the area, collect cars, and ride their motorcycle on weekends.
There is something quietly revealing in that picture. A man who has devoted his professional life to understanding how human beings interact with designed objects chooses, in his own time, to be close to animals and open land, two things that exist entirely outside the logic of product design. It suggests that his interest in the human experience extends well beyond method: it is a genuine curiosity about how people live, move, and make sense of the world around them.
That curiosity, sparked by an unexpected course discovery during his university years, continues to shape his work today.
