What is an 'audit trail' in logistics information systems?

• A. A record of all transactions and movements enabling traceability and accountability.
• B. A schedule of quarterly spending.
• C. A list of suppliers with no transaction history.
• D. A record of weather impacts on shipments.

Answer: (A)

In logistics information systems, an audit trail is a chronological record of every action, transaction, and movement within the system, created to preserve traceability and accountability. It shows who did what, when, and what data changed, so you can follow the lifecycle of a shipment, inventory adjustments, order status updates, and system edits. This kind of visibility supports auditing, compliance, discrepancy resolution, and security checks, which are all crucial in complex logistics networks with many hand-offs. The best choice describes this comprehensive log of transactions and movements that enables traceability and accountability. A budgeting schedule focuses on spending plans, not system actions. A supplier list without transaction history lacks the movements and changes you’d need to trace events. A record of weather impacts tracks external conditions, not the internal actions and movements within the system.
