Reviewing Milestones

Third Party Assurer (TPA) Verification Checklist

You can use this checklist as a final sense-check before submitting your Third Party Assurer Comments.

Pre-assessment:

Before reviewing any deliverables, confirm the following:

• Independence confirmed I have no financial, personal, or professional ties to the vendor or outcome of this milestone.

• Right expertise I have the appropriate knowledge to assess this specific deliverable.

• Proposal reviewed I have read the original proposal and understand the milestone acceptance criteria and deliverables in the signed contract.

• Scope is clear I know exactly what “complete” looks like for this milestone.

Assessment: Evidence & Quality

When reviewing the milestone, validate both completion and quality:

• Evidence provided The vendor has supplied clear, tangible proof (e.g. documentation, code, data, outputs).

• Evidence is sufficient The materials provided are enough to confidently verify completion.

• Matches the proposal The deliverable aligns with what was originally promised.

• Quality standard met The output meets expected technical or professional standards (not just minimum effort).

• Clarity & transparency Outputs are understandable, even for non-technical stakeholders where relevant.

• No major gaps or risks Any issues, inconsistencies, or red flags have been identified.

Final Attestation: Reporting

Before submitting your review, ensure your output is clear and actionable:

• Clear outcome provided I have given a definitive result (e.g. Pass / Fail / Conditional).

• Justification included My decision is supported by specific, evidence-based reasoning.

• Actionable feedback (if needed) If not approved, I have clearly outlined what needs to be addressed.

• Objective tone maintained My report is factual, unbiased, and free from personal opinion.

Final Sense Check

Before submitting, ask yourself:

“Would someone outside this project feel confident that funds were well spent based on my review?”

• Yes — the assessment is clear, evidence-based, and trustworthy

• No — further review or clarification is needed

Key Reminder

You are the independent control in the process.

Your role is not to support delivery; it is to verify it objectively. If evidence is unclear or quality is not met, it is your responsibility to reflect that in your comments.

We want to ensure Treasury funds are being spent in line with the agreed contract.
