Which characteristic makes a daily log useful in operations?

• A. It records factual, event-related information
• B. It remains informal and undocumented
• C. It reproduces other departments' work
• D. It includes only daily summaries

Answer: (A)

A daily log is most useful when it records factual, event-related information with clear, time-stamped details. This objective record captures what happened, when, where, who was involved, and what actions were taken, providing a reliable basis for shift handoffs, problem resolution, and future reference. It supports accountability, trend analysis, safety and quality monitoring, and helps peak operational decisions by showing exact events and outcomes.

Notes on why the other ideas aren’t as helpful: keeping the log informal and undocumented makes it unreliable for real-time problems or audits; reproducing other departments’ work doesn’t add value and can cause confusion; and including only daily summaries omits the specifics—like dates, times, people, and actions—needed to understand incidents or verify what occurred.
