Practical assurance resources for programme sponsors, boards, delivery leaders and organisations buying technology from third parties.
These materials are designed to support real governance decisions. They explain what independent assurance should examine, what adequate evidence looks like and where supplier self-assessment creates avoidable exposure.
The problem these resources address
Programme sponsors and buyers are frequently asked to judge supplier delivery without a clear standard for evidence, independence or readiness. Generic templates rarely explain which claims matter, what must be demonstrated or when a gap should stop a decision.
The control gap
Guidance can improve the questions asked, but it cannot create independent assurance by itself. The client still needs a defined mandate, access to evidence, a reporting route to governance and practitioners who are separate from the delivery they examine.
How to use the material
- Use the capability and service material to define the assurance need and engagement boundary.
- Use the readiness checklist before commissioning a review or approaching a major decision.
- Use the executive briefing to align sponsors and programme boards on supplier self-assessment risk.
- Use the sample report to establish the level of evidence, clarity and decision support expected from assurance.
- Escalate gaps into an independent review where consequence, uncertainty or conflict makes self-assessment insufficient.
The operating method is explained in How We Assure. The core proposition is set out in Independent Delivery Assurance.

Evidence these resources help you request
The material helps buyers ask for the evidence that supports a real decision: approved obligations and acceptance criteria, integrated plans and dependencies, supplier delivery records, architecture decisions, quality and test evidence, migration reconciliation, cutover readiness, operational acceptance and accountable risk decisions.
Routes into specialist assurance
- Use Supplier Delivery Assurance where supplier reporting, obligations or recovery commitments require independent challenge.
- Use Programme Health Checks and Recovery where viability, governance or forecast confidence is in question.
- Use Quality and Test Assurance where evidence of solution quality or business acceptance is weak.
- Use Data Migration and Cutover Assurance where data fitness, transition or operational readiness drives the decision.
- Use Fractional Assurance Leadership where an organisation needs continuing senior challenge without permanent internal headcount.
Outputs and decision value
Used properly, these resources create a clearer assurance brief, a stronger evidence request and a more explicit governance decision. They help leadership distinguish supplier narrative from demonstrated position and identify where independent examination is required before risk is accepted.
Engagement route
Discuss an independent assurance review. Initial scoping should identify the decision, delivery ownership, available evidence and the consequence of proceeding with an unsupported position.
Resources are not a substitute for assurance
A checklist can expose a gap. It cannot independently test the evidence or accept risk on behalf of client governance.
