Which statement about usability testing is NOT true?

• A. Lack of user input in design and testing is a major cause of system implementation failure
• B. Usability testing can be conducted inexpensively in hospitals
• C. Nurses and physicians should be involved in systems design
• D. Usability testing can be conducted only by human engineers

Answer: (A)

Usability testing centers on how real users interact with a system and how their feedback guides design to fit actual clinical workflows and safety needs. The most important idea is that testing benefits from involving those who will use the system—nurses, physicians, and other clinicians—so the design supports their tasks, language, and environment. It can be done inexpensively in hospital settings by using low-fidelity prototypes, simple task scenarios, and small user groups to uncover issues early and iterate quickly. The statement that is not true is that usability testing can be conducted only by human engineers. In practice, end users and a broader multidisciplinary team—clinicians, IT staff, and usability professionals—participate in testing to ensure the system works in real care contexts. Engineers may facilitate or analyze tests, but restricting usability testing to engineers misses essential clinical insight and undermines the goal of aligning the tool with actual workflows.
