Audit Trail

Chronological record of changes, approvals or transactions that allows actions and data to be traced.

Examples

01The audit trail in the batch record system shows who changed the mixing temperature, when, from what value and why.
02In the governance review, auditors sample 20 changes and check that each has a complete audit trail with approval.
03Any change to a validated system without an audit trail is blocked, so changes cannot bypass the approval process.
