Evangelising and Awareness of AI in Internal Audit

Leading organizations and industry experts are actively raising awareness and promoting the adoption of AI within the internal audit community. As a result, several initiatives are gaining traction:

Thought Leadership and Publications: Organizations like The IIA and KPMG are publishing articles and reports that delve into the benefits, challenges, and practical applications of AI in internal audit. For example, KPMG’s report “Revolutionizing Internal Audit with the Power of AI” highlights how AI enhances risk assessment, fraud detection, and compliance monitoring. These publications are vital resources for auditors.
Conferences and Webinars: Industry events and webinars provide platforms for experts to share their insights and experiences with AI in internal audit. The IIA’s podcast “All Things Internal Audit” features discussions on the practical applications of generative AI in the workplace and its impact on internal auditors. These forums foster knowledge-sharing and provide actionable insights to internal audit professionals.
Training and Development: Organizations are developing training programs to equip internal auditors with the necessary skills and knowledge to leverage AI effectively. These forums foster knowledge-sharing and provide actionable insights to internal audit professionals.
Collaboration and Knowledge Sharing: Platforms like AuditBoard are facilitating collaboration and knowledge sharing among internal audit professionals. This enables practitioners to learn from each other’s experiences and best practices in AI implementation. AuditBoard’s “2025 Focus on the Future” report provides insights into the current state of AI adoption in internal audit and highlights key trends and challenges.

Keep it simple

Starting with simple AI use cases and scaling up gradually is often recommended. For example, specifying contexts and formats ensures generative AI aligns with audit objectives effectively.

Furthermore, it’s important to highlight the innovative use of AI in generating audit documentation and providing data-driven insights. AI can generate code to help create audit memos with key findings, supply data-driven insights, and even provide recommendations using predictive analysis that the auditor may not have previously considered.

Experiments with AI in Internal Audit

Internal audit departments are actively experimenting with AI across several areas. For example:

Data Analytics: AI is being used to analyze large datasets, identify anomalies, and provide insights into financial transactions and operational processes. This enables auditors to identify potential risks and fraud more efficiently.
Risk Assessment: AI-powered tools are being used to automate risk assessments, providing a more comprehensive and dynamic view of organizational risks. This allows auditors to focus on high-risk areas and allocate resources more effectively.
Compliance Monitoring: AI is being used to monitor compliance with regulatory standards and internal policies. This helps organizations detect and address compliance issues in real-time.
Fraud Detection: AI algorithms are being used to identify patterns and anomalies that may indicate fraudulent activities. This enables auditors to proactively detect and prevent fraud.
Audit Automation: AI is being used to automate routine audit tasks, such as data extraction, document review, and report generation. This frees up auditors to focus on more strategic and analytical tasks.

Case Study: Data Analytics in a Large Internal Audit Department

A Detroit-based audit team leveraged AI tools for analyzing Accounts Payable and the General Ledger. For instance, they hired experts and developed analytics routines. Consequently, their success underscores AI’s practical benefits in traditional audit processes.

Building upon these experiments, internal audit departments are now actively integrating AI into their core processes.

Integration of AI in Internal Audit Processes

AI is transforming core audit processes by improving efficiency and accuracy. For example:

Continuous Auditing: AI-powered tools enable continuous monitoring of financial data, transactions, and internal controls. This real-time oversight helps internal auditors detect issues as they arise, rather than waiting for periodic audits. AI-driven approaches offer comprehensive analysis and real-time insights, leading to more accurate results.
Predictive Analytics: AI algorithms can analyze historical data and identify patterns that might indicate fraud, errors, or control weaknesses. This allows auditors to proactively address potential risks and improve the effectiveness of internal controls.
Risk Assessment: AI enables more frequent and accurate risk assessments by allowing for real-time sharing of risk information and automation of data analysis. This allows organizations to proactively identify and mitigate risks.
Enhanced Reporting: AI can generate insightful and customized reports, making it easier for auditors to communicate their findings effectively to management and stakeholders. These reports can also highlight areas that require immediate attention. AI can also be used to produce data-driven insights and visualizations for audit committee and board reporting, facilitating deeper discussions and more effective communication.

Enhanced Reporting to Stakeholders

AI can generate reports and visualizations that present complex information in a clear and concise manner, allowing auditors to communicate findings and recommendations more effectively to stakeholders. A future state for audit committee reporting could use AI to develop predictive models that estimate the likelihood of future risks based on current results, facilitating deeper discussions between audit leaders and the audit committee.

Process Automation: AI can automate routine and repetitive tasks, such as data gathering, documentation, and report generation. This allows internal auditors to focus their efforts on more complex and strategic activities. AI can also help improve the quality and speed of fieldwork, enabling auditors to perform their tasks more efficiently and effectively.

A key insight from this integration is that AI allows auditors to shift their focus from tedious tasks to the interpretation of data. By automating time-consuming tasks, AI frees up auditors to dedicate more time to analyzing data and drawing meaningful conclusions.

Innovation with AI in Internal Audit

Internal audit departments are exploring innovative uses of AI to further enhance their capabilities:

Natural Language Processing (NLP): NLP analyzes unstructured data like emails to uncover risks and compliance issues.
Machine Learning (ML): ML creates predictive models, identifying potential risks based on historical trends.
AI-powered Audit Agents: AI agents are being developed to automate specific audit tasks, such as transaction testing and control assessments. This can help increase audit coverage and reduce the human hours required for these tasks. For example, ZBrain enables the automation of transaction testing and control assessments, which can help increase audit coverage and reduce the human hours required for these tasks.
Generative AI: This technology automates tasks such as generating audit reports and analyzing raw data, streamlining workflows.

These innovations demonstrate the ongoing evolution of AI in internal audit. By exploring new technologies and applications, internal audit departments are pushing the boundaries of what’s possible and creating new opportunities to add value to their organizations.

The Future of AI in Internal Audit

The future of AI in internal audit is promising, with several trends gaining momentum:
