DisInnova's internal audit advisory services provide independent, senior advice on internal audit strategy, planning, methodology, assurance quality, reporting, governance and function effectiveness. The work is shaped around the priorities of heads of audit, audit committees and executive sponsors who need a sharper, more useful assurance contribution to the board.
Engagements span audit committee advisory, methodology and working practice review, risk-based audit planning, internal audit reporting and external quality assessment (EQA) readiness — calibrated to the maturity of the function and the expectations of its stakeholders.
The emphasis is on insight, judgement and proportionality rather than mechanical compliance. Where helpful, we support function reviews and quality assessment readiness with a clear improvement roadmap, and consider how technology and data analytics can sharpen audit coverage without overcomplicating the operating model.
Internal audit is also considered alongside the wider assurance model, helping leadership teams achieve coherent oversight across the three lines of defence and a more deliberate assurance contribution to the board.
Where an organisation needs a wider redesign of the function — strategy, operating model, technology, skills and reporting — DisInnova provides dedicated internal audit transformation services for an end-to-end transformation approach. This service sits within DisInnova's wider advisory services for boards and executive teams.
Part of DisInnova's senior business advisory services practice.
When internal audit advisory is relevant
- —Ahead of an external quality assessment or peer review
- —When the audit plan no longer reflects the firm's risk profile
- —When audit reporting is not consistently driving action
- —When assurance overlaps between functions create noise rather than clarity
- —When the audit function is being scaled, restructured or repositioned
What internal audit advisory services include
- —Audit strategy and mandate — refreshing the internal audit charter, positioning and value proposition for the board and audit committee
- —Risk-based audit planning — risk-based audit universe, dynamic planning and alignment with the enterprise risk profile
- —Methodology and working practices — risk assessment, scoping, fieldwork, evidence, conclusions and consistency of execution
- —Audit committee reporting — clearer, decision-useful reports that drive action rather than describe activity
- —EQA readiness and quality improvement — preparation for external quality assessment and a structured internal quality programme
Internal Audit Advisory Aligned to the Global Internal Audit Standards
DisInnova's internal audit advisory work is informed by the Global Internal Audit Standards™ issued by The Institute of Internal Auditors. The standards set expectations across the governance of the internal audit function, strategic planning, quality, engagement performance, communication of results and monitoring of management action plans.
Engagements consider how the function evidences independence and authority, how the audit strategy aligns with stakeholder needs, how methodology supports consistent and decision-useful engagements, and how quality assurance and improvement arrangements are designed and operated. Where helpful, we support heads of audit with GIAS readiness assessments, methodology refreshes and EQA preparation that reflect the updated expectations.
DisInnova is an independent advisory firm and is not affiliated with, endorsed by or certified by The Institute of Internal Auditors. References to the Global Internal Audit Standards are for context only.

Do you co-source or outsource audits?+
DisInnova focuses on advisory uplift to internal audit and the wider assurance model rather than ongoing co-sourcing of audit delivery.
Can you support audit committee effectiveness?+
Yes. We provide independent perspective on assurance reporting and committee inputs, and can facilitate focused sessions for the committee.
Do you support EQA preparation?+
We help heads of audit prepare in a structured way, identifying improvement areas and evidence ahead of the formal external assessment.
How is this different from internal audit transformation?+
Internal audit advisory focuses on independent advice and uplift to methodology, planning, reporting and assurance quality. Internal audit transformation is an end-to-end redesign of the function's strategy, operating model, technology, skills and stakeholder impact — see our dedicated internal audit transformation services.
