Question 1
A financial services company is developing a new mobile banking app. During a usability review, it is noted that the process for transferring funds between accounts requires six distinct steps, whereas a key competitor's app accomplishes the same task in three. While the process is error-free and users eventually succeed, feedback indicates it feels cumbersome. According to the ISO 9241-11 definition of usability, which component is most negatively impacted by this design?
Answer and explanation
Correct answer: B
Efficiency, in the context of ISO 9241-11, relates to the resources expended (e.g., time, effort) to achieve a goal. A six-step process that could be three steps is less efficient. Effectiveness is the ability to complete the goal at all, which users could do. Satisfaction relates to the user's feelings about the interaction, which is also impacted but is a consequence of the poor efficiency. Accessibility relates to use by people with disabilities and is not the primary issue described.
