A project manager argues that usability testing is a luxury that can be skipped to meet a deadline. Which counterargument best demonstrates that usability is a quality characteristic with measurable business impact?

Usability is required by law for all software products.

Usability is a subjective preference and cannot be measured objectively.

Usability issues can lead to increased support calls, user errors, and lost productivity, which have direct costs.

Usability testing is the only way to ensure software is free of bugs.

A hospital is deploying a new patient-monitoring system. The system will be used by nurses on busy wards, often while wearing gloves, and the monitors are mounted on carts that move between rooms. Which context-of-use component is most likely to have the greatest impact on usability in this scenario?

Equipment, because touchscreen interactions must work with gloved hands and on moving carts.

Tasks, because monitoring patients is a complex medical procedure.

Environment, because the ward is noisy and busy.

Users, because nurses have different levels of technical skill.

A usability test of a banking app shows that users complete transactions quickly, but the error rate is high, and satisfaction scores are low. The team must decide which measure to improve first. Which approach is most justified?

Focus on satisfaction, because it is the most important measure.

Focus on increasing speed, because users value efficiency.

Focus on reducing errors, because errors directly undermine effectiveness and likely contribute to low satisfaction.

Focus on all measures equally, because they are independent.

A usability test of a tax-preparation software shows that participants complete the task, but they frequently make errors and need help from the moderator. Which usability measure would best capture the need for assistance?

Error rate, because errors often lead to asking for help.

Satisfaction, because users who need help are less satisfied.

Time on task, because help increases the time.

Task success, because it counts whether the task was completed with or without help.
