Internal Audit as a Strategic Asset

In some organisations, internal audit is still seen mainly as a checking function: useful for confirming policy compliance, but peripheral to strategic discussion. That perception tends to narrow its mandate and reduce its influence. The Institute of Internal Auditors’ guidance for audit committees notes that internal audit is not always widely recognised for its full value, and that boards and executive management play an important role in elevating the function so it is understood as a contributor to governance, risk management, and internal control improvement.^[2]

Why internal audit is sometimes marginalised

That narrow perception is increasingly out of step with the formal role of internal audit. The IIA’s Global Internal Audit Standards define internal auditing as an independent, objective assurance and advisory service designed to add value and improve operations, helping the organisation accomplish its objectives through a systematic, disciplined approach. They also require the audit plan to be risk-based and dynamic, adjusting to changes affecting the organisation. Internal audit is therefore meant to do more than verify routine compliance; it is expected to remain relevant to changing risk and governance needs.

The limits of a purely compliance-driven model

A compliance-led audit model still has an important place. Organisations need assurance over core controls, regulatory obligations, and policy adherence. But when internal audit is defined too narrowly, it can become disproportionately focused on low-value testing, historical exceptions, and standardised findings that management already expects. COSO’s internal control guidance is helpful here: effective internal controls have value beyond compliance and external financial reporting, helping organisations articulate purpose, set objectives and strategy, and grow with confidence and integrity. If control is broader than compliance, internal audit’s lens should be broader as well.^[1][4]

What makes internal audit strategically useful

The strategic value of internal audit usually becomes clearer when it is aligned with organisational objectives and risk appetite rather than organised solely around recurring control themes. The IIA’s guidance on risk-based audit planning says internal audit should focus limited resources on insightful, proactive, and future-focused assurance and advice on an organisation’s most pressing issues. This is especially relevant when organisations are navigating major transformation, digital change, operating model redesign, or regulatory pressure. In those environments, internal audit can be strategically useful by assessing whether governance processes support effective strategic and operational decisions, whether risk oversight is functioning as intended, and whether control maturity is keeping pace with change.^[5][6]

Independence remains essential — but so does relevance

One reason some leaders hesitate to position internal audit more strategically is concern about independence. That concern is valid. Internal audit should not become a substitute for management, nor should it assume ownership of risk decisions it later needs to assess. The IIA’s Three Lines Model addresses this clearly: internal audit, as the third line, provides independent and objective assurance and advice on the adequacy and effectiveness of governance and risk management, while maintaining independence from management responsibilities. Strategic relevance should therefore not be confused with operational ownership.^[3]

What a strategically operating internal audit function looks like

In practice, a strategically operating internal audit function often shows a few recognisable traits. Its plan is clearly linked to enterprise risk, business objectives, and major change initiatives. Its reporting helps management and the board act, rather than simply record exceptions. It is willing to look across governance, culture, incentives, decision processes, and control effectiveness, not just transaction-level compliance. Equally, it communicates with sufficient timeliness that issues can still be addressed before they harden into losses, regulatory problems, or strategic setbacks.^[2][5]

For boards and audit leaders, the practical question is not whether internal audit should stay independent; it must. The more useful question is whether the function’s work is sufficiently connected to the decisions, risks, and control conditions that matter most to the organisation now. When that alignment exists, internal audit is no longer seen as a narrow checking activity. It becomes a more credible and useful governance asset.^[1]
