The requirement that a system be easy to use is an example of which type of requirement?

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

Answer: (C)

Focusing on how users interact with the system—the ease of use—this centers on usability and the user experience. Usability is studied within human-computer interaction, which covers how intuitive an interface is, how quickly a user can learn it, and how efficiently tasks can be completed with minimal errors. This differs from technical requirements, which specify hardware, software, performance, or security constraints, and from functional requirements, which describe specific functions the system must perform. So the requirement for the system to be easy to use fits under the human-computer interaction category.
