The requirement that the system be easy to use would be an example of what type of requirement?

• A. Functional Requirement
• B. Technical Requirement
• C. Human Computer Interaction Recruitment
• D. Incomplete Requirement

Answer: (A)

The important idea here is that usability, or being easy to use, describes how well the system supports the user rather than a specific operation it must perform. That makes it a non-functional quality attribute. Functional requirements specify concrete actions the system must take (what it does), such as processing a transaction or generating a report. Usability focuses on how easy and efficient those functions are to use, how the user interface supports tasks, learnability, and accessibility. For example, a functional requirement might state that the system shall allow a nurse to enter vitals, while a non-functional usability requirement would specify that the interface should allow common tasks to be completed in two clicks or less. So, easy-to-use is classified as a non-functional requirement, reflecting quality rather than a specific function.
