Human Factors

Depending on the specific product or process involved, a human factors expert witness typically has an advanced degree and extensive experience in industrial engineering, mechanical engineering, and/or biomechanical engineering. Experts in this field may have an affiliation with an industry organization such as the Industrial Designers Society of America (IDSA) or the Human Factors Ergonomics Society (HFES), and could also be certified as a Human Factors Engineering Professional (BCPE).

A human factors expert witness could provide expertise in intellectual property matters, such as a patent litigation or a trade secret dispute, or a patent case or proceeding in the International Trade Commission (ITC). A human factors specialist could also be called in for an accident reconstruction, product liability, personal injury, or failure analysis project.

Litigation support by a human factors expert witness could include an expert report, forensic engineering, expert opinion, and expert testimony in trial court. In a high-profile case, or litigation involving a significant financial stake, the lead attorney may request a technical expert with prior expert witness testimony experience.
