Human system integration focuses on which aspect of system design?

• A. Focuses attention on the human part of the system.
• B. Focuses on mechanical reliability alone.
• C. Deals with financial auditing of support contracts.
• D. Sets environmental compliance standards.

Answer: (B)

Human system integration centers on the human element in system design, ensuring people can operate, maintain, and interact with the system effectively and safely. It considers usability, cognitive workload, training, procedures, and the human–machine interface to optimize performance and safety. That’s why the best option is that it focuses attention on the human part of the system. Options about mechanical reliability, financial auditing, or environmental compliance describe other aspects of a program, not the human-centered design focus.
