Lesson 9 of 12 · 6-minute lesson
Check data and suppliers
Keep known facts, supplier claims, documents and independently reviewed evidence separate.
For: Data owners, procurement, security, privacy and supplier owners
This lesson uses National AI Centre guidance: Data quality checklist, Questions to ask AI suppliers.
The problem
Incomplete sources or unverified supplier claims can undermine a well-designed human-review process.
The choice
Priya checks data quality while Maya records supplier answers and the evidence supplied for them.
What you will learn
By the end of this lesson
- Review information quality.
- Record supplier answers and documents.
- Distinguish claims from reviewed evidence.
The pivotal moments
What changes—and why it matters
Moment 1
Review information quality
What the person does
Priya checks accuracy, completeness, where the information came from, who owns it and whether it is current.
What the workspace records
An important gap is recorded with an owner.
Notice
Known gaps remain visible during assessment.
Why it matters
The team does not assume source quality.
Moment 2
Ask the supplier
What the person does
Maya records answers about data, controls, monitoring and incidents.
What the workspace records
Answers sit beside the documents the supplier provided.
Notice
A plausible answer is still a supplier claim.
Why it matters
Procurement and reviewers can see what needs checking.
Moment 3
Record what the evidence shows
What the person does
Maya marks each item as claimed, supplied or independently reviewed.
What the workspace records
Evidence records state which claim they may support.
Notice
Uploading a file does not close a condition.
Why it matters
Assessment readers can distinguish facts from unresolved claims.

The complication
The difficult part stays visible
Some supplier answers are plausible and documented but have not been independently verified.
The outcome
Confirmed facts, claims, supplied documents and evidence gaps remain visibly separate.
Check your understanding
Does a supplier document prove its claim?
Show the answer
Not automatically. The document can be supplied evidence, but a reviewer must decide what it supports and whether independent checking is needed.
Key points
Remember these three things
- Record important information gaps.
- Treat supplier answers as claims.
- Review evidence before closing conditions.
