By role / Internal auditor

Your standards tell you how to audit. They do not tell you what to look at.

The auditing standards govern independence, evidence and reporting. Establishing the criteria is your job, and past contract closure there is very little published to build them from.

You have been asked to give assurance on a capital programme, or on an entity that is building assets it will shortly have to run. You are not the engineer, and none of your standards makes you one.

Standards governing your work

  • Government Auditing Standards, 2024 revision, GAO-24-106786, effective for performance audits beginning on or after 15 December 2025

    Nine chapters: the foundation and use of the standards, general requirements for compliance, ethics and independence, competence and continuing education, quality management and peer review, and then the conduct and reporting of financial audits, attestation engagements and performance audits. Not one of them names a subject. GAGAS defines planning to include determining objectives, scope and methodology and establishing criteria to evaluate matters subject to audit, which puts the criteria on the auditor rather than in the standard.

  • Global Internal Audit Standards, Institute of Internal Auditors, effective 9 January 2025

    Five domains and 15 principles covering the purpose of internal auditing, ethics and professionalism, governance of the function, its management, and the performance of services. The same shape as GAGAS: how the function is run and how an engagement is conducted, not what a capital programme should be measured against.

  • INTOSAI GUID 5280, Guidance for Audits of Public Procurement, 2022, free in full

    The closest thing to a published, global question set for this ground. Three phases, pre-tendering, tendering and post-award, with annexes carrying roughly a hundred possible audit questions and a table of integrity risks at each step. It is also explicit about its own limits: paragraph 62 says the questions are a menu to choose from, are not exhaustive, and need to be completed with the applicable or designed audit criteria.

Where that stops

GUID 5280 ends where the contract does. Its last post-award question asks whether the contract was closed only once the contracting authority formally recognised that all deliveries were complete and payments were released. Everything this publication is about starts one step after that: the asset exists, somebody has to run it, it has to appear in a register at a value somebody can defend, and it will cost more to keep than it did to build. The only place the asset register appears in GUID 5280 at all is in the integrity risk table, as something that might be stolen from before it is recorded. Whatever criteria you apply past that line, you will have written them yourself. What follows is a set you can argue with.

Whether the decision to build was made on evidence that would survive being read back, and whether the governance that approved it could have said no.

What to examine

Instruments

  • The question bank

    Every question this publication asks, drawn from the framework and the articles, filtered by stage and by source, printable.

  • Lifecycle cost sensitivity

    Take three real costed buildings and watch the construction share of lifecycle cost move from 66% to 7% while the data stays exactly the same.

Whether the reported position is the real one, and whether the assurance already being performed adds up to coverage or only to activity.

What to examine

  • Baseline integrity

    Is the baseline currently being reported against the one that was sanctioned, and if not, is every step between the two documented?

  • Change, planned and unplanned

    Are changes assessed before they are made, and does anyone examine changes that were made without being assessed?

  • Forecast credibility

    Does the forecast reflect what is now known, or does it reflect what was committed?

  • Externally provided processes and services

    Where activities that affect the asset have been placed outside the organisation, has the organisation retained the ability to know whether they were done?

  • Competence of whoever is assuring

    Do the people performing this assurance understand the thing they are examining, and where they do not, is the gap covered by someone who does?

Instruments

  • Earned value calculator

    From planned value, earned value and actual cost, the variances and indices; add the budget at completion for the estimates at completion. Formulas shown and cited.

  • Reporting history check

    It does not ask whether the project is healthy. It asks whether the reporting on it has ever produced a signal, across the whole history rather than this month.

Whether the conditions for taking over were met or waived, and whether anybody tested the receiving organisation rather than only the plant.

What to examine

Instruments

  • Operational readiness check

    Put the questions a readiness review will ask, condition by condition, and name the blockers with their references. The percentage counts your answers; the blockers apply a rule.

  • Turnover package composer

    What has to change hands at taking over, grouped by what it is for rather than by who produced it, with what depends on each item and how to tell whether it is any good.

  • What follows the certificate, and when

    Enter one completion date and get every consequential date under your contract regime, each computed from the clause that sets it.

Whether the records describing what the entity owns are true, and whether the management system around them has ever changed a decision.

What to examine

Instruments

  • Asset register package

    The financial register, the technical register and the crosswalk between them, generated together as one Excel workbook. The two registers share the asset tag, and every column states the requirement behind it.

  • Criticality screen

    Find the assets that have to be looked at separately, and see what a likelihood times consequence ranking does to that list.

In the asset lifecycle method

This page composes material published elsewhere on this site and adds no claim of its own. The arrangement into stages is this publication’s, as the framework says at length; the requirements above are quoted from documents that are free to read and linked next to each. Where a stage is empty for this role, it says so rather than being left out.
