Which Nielsen heuristic emphasizes providing visible system status so users know at a glance what is happening?

• A. Help and documentation
• B. Flexibility and efficiency of use
• C. Visibility of system status
• D. Aesthetic and minimalist design

Answer: (C)

Visible system status is about keeping users informed of what the system is doing in real time. When you see a spinner, a progress bar, or a message like “Saving…” or “Upload complete,” you understand the current state and what to expect next. This immediate feedback helps users form an accurate picture of the system, reduces uncertainty, and lets them decide their next action without guessing. That direct conveyance of status at a glance is exactly what this heuristic aims for.

The other options address different goals: help and documentation provides guidance when you need it, not ongoing feedback about current operations; flexibility and efficiency of use focuses on shortcuts and adapting the interface for experienced users; aesthetic and minimalist design emphasizes reducing unnecessary elements, which can be important but doesn’t specify communicating ongoing status.
