What "objective evidence" means

What auditors are expected to record as evidence and why it matters.

Written by Caim Hermoso

Who this is for: Auditors, and administrators configuring evidence requirements.

Objective evidence is the factual record of what the auditor saw, read, measured or was told — stated in a way that someone else could check.

Good objective evidence is specific:

Reviewed the process owner register (rev 4, dated 12/03/2026). Entries absent for Departments 4, 7 and 11 of 12.

Weak evidence is an opinion or a conclusion:

Records not properly maintained.

The difference matters because the evidence is what survives the audit. When someone reads the report in six months, or a certification body challenges the finding, the evidence is what supports it.

Four kinds of evidence are recognised in the module and can be required per template or per clause:

Type

What it means

Document

A record, procedure, certificate or log that was reviewed

Observation note

Something physically seen on site

Test / measurement

A reading, calibration check or test result

Interview note

What someone said, and who they were

A photograph can also be attached to a finding, and can be made required.
