As the business landscape becomes increasingly complex, the expectations placed on Chief Audit Executives (CAEs) continue to evolve.
With the recent release of the Institute of Internal Auditors’ (IIA) Global Guidance on the Competency of the Profession, it’s timely to reflect on what defines excellence in this critical leadership role.
While the role of a CAE encompasses a wide range of skills and responsibilities, some foundational attributes remain non-negotiable. These are the core pillars that support both credibility and effectiveness in a rapidly changing governance environment.
Business and Cultural Acumen
An effective CAE must possess a deep understanding of the organization’s business model, strategic priorities, and importantly, its unique culture.
This goes beyond general industry knowledge. It involves grasping the nuances of how decisions are made, what drives performance, and how values are operationalized across the enterprise.
Without this level of insight, internal audit risks becoming disconnected from the business, delivering findings that are technically sound but practically irrelevant.
Alignment with the business context is what allows audit functions to deliver not just assurance but meaningful strategic value.
Trust and Respect Across the Enterprise
Influence is a product of credibility, and credibility is built on trust.
A successful CAE must earn and maintain the trust and respect of key stakeholders: the Board, senior leadership, business unit heads, and employees.
This trust is not granted by title. It’s built over time through professionalism, fairness, and a demonstrated understanding of business realities.
Without it, internal audit struggles to gain traction. With it, audit becomes a respected voice in the room – one that can shape risk conversations, challenge constructively, and drive organizational improvement.
Mastery of Internal Audit Standards in Practice
While theoretical knowledge of the International Professional Practices Framework (IPPF) is essential, true competence lies in how that knowledge is applied in the field.
A great CAE brings the standards to life, not by quoting them, but by embedding them into processes, methodology, and decision-making.
This includes translating audit standards into risk-focused work programs, ensuring compliance with integrity, and adapting guidance to the organization’s maturity and scale.
In short, excellence in internal audit isn’t about rigid adherence, it’s about principled application that delivers value.
Foundational Pillars, Not Exhaustive Traits
Of course, the role of a CAE demands more than these three pillars. Leadership, communication, stakeholder management, and forward-looking risk sensing are all part of the equation.
But without business and cultural acumen, trust and respect, and practical mastery of audit standards, none of the other capabilities can thrive.
These are the bedrock upon which everything else is built.
Redefining Excellence in Audit Leadership
As internal audit continues to mature as a strategic function, so too must our expectations of its leaders.
In 2025 and beyond, the most effective CAEs will not be those who merely tick the boxes of technical competence, but those who blend professional rigor with relational depth and contextual intelligence.
Now is the time to raise the standard.
