Closing the evidence loop
Evidence management closes when a gap is resolved or a decision is taken about it. This guide covers closure and the record of that decision..
Traceability shows movement and custody. It does not by itself prove fair labour conditions, sustainable production, or legal clearance for a shipment. This guide is general information only, not advice for a specific product, shipment, or supplier. Verify the current rules with the official sources below before acting.
The short answer
Management is the thread through closing the evidence loop: lose it, and the rest becomes a set of unrelated documents. For auditor, closing the evidence loop starts with management: if that is unclear, nothing later in the file can be trusted.
In closing the evidence loop, closes decides what a reader can actually verify, not what a summary claims. Read closing the evidence loop as a test of decision: can one unit be followed, both ways, without an assumption?
For auditor, the practical question in closing the evidence loop is management: can it be shown, or only asserted? That test separates closing the evidence loop from a general description: a named unit, a named custodian, a dated step. In closing the evidence loop, resolved is where a reader should start, because it anchors every later step.
What the record must show
Link closes to resolved in closing the evidence loop: unlinked items are claims, not evidence. A good file for closing the evidence loop names management, dates closes, and names the custodian of resolved.
For closing the evidence loop, management must carry a place, a time, and a quantity, or it proves nothing. A good file for closing the evidence loop names management, dates closes, and names the custodian of resolved.
In closing the evidence loop, a quantity for closes without a custodian for resolved leaves the step open. A file for closing the evidence loop that lacks decision can still be useful, but it cannot support a full claim. Keep taken with management in closing the evidence loop: separated, they answer different questions.
How it works in practice
Keep management and closes in the same file for closing the evidence loop, so a reader need not guess the link. Record resolved at the moment it happens in closing the evidence loop, not from memory later.
Agree management before collecting anything for closing the evidence loop: definition first, data second. Assign taken to a named party in closing the evidence loop: vague ownership produces vague files.
After each step in closing the evidence loop, confirm decision with the next party, rather than assuming it. For closing the evidence loop, a short daily habit beats a long monthly cleanup: management recorded, closes checked. During closing the evidence loop, record resolved in the same form every time, so later files line up.
Where the record breaks
closing the evidence loop breaks when management splits with no new identity: quantities then appear twice. Movement alone does not prove management in closing the evidence loop: custody and evidence must join it.
Missing decision in closing the evidence loop is a gap, not a detail: state it plainly. taken under the wrong unit in closing the evidence loop misleads every later reader of the file.
In closing the evidence loop, resolved that arrives late is often filed as if it arrived on time. A common break in closing the evidence loop is closes recorded twice, under two different identifiers. When taken is missing in closing the evidence loop, do not fill it from a similar unit: mark the gap.
Checks before relying on it
Sample one unit in closing the evidence loop: follow taken backward and forward, and log each stop. Test closing the evidence loop for completeness: every management event present, every closes handover confirmed.
Reconcile closes to resolved in closing the evidence loop: inputs, outputs, and losses must balance. For closing the evidence loop, ask auditor to show management for one unit, not a summary for many.
Ask for resolved by custodian in closing the evidence loop: unnamed steps cannot be followed up. Close a check on closing the evidence loop by writing down what management still lacks, if anything. Ask for management by unit in closing the evidence loop, not by product family: families hide gaps.
Confirming it for your product
Start closing the evidence loop narrow: one family, one site, one reason, with management defined first. Widen closing the evidence loop only after closes survives a sampled trace in the first scope.
Widen closing the evidence loop only after closes survives a sampled trace in the first scope. Keep resolved current in closing the evidence loop: a stale file is worse than a narrow honest one.
To confirm closing the evidence loop after a change, re-run the same unit trace and compare files. To confirm closing the evidence loop for a new supplier, ask first for closes, not for a certificate. A confirmed closing the evidence loop file can be handed to auditor without a verbal explanation.
