Internal audit and external affairs are two distinct processes that serve different purposes. However, both are equally essential components of effective corporate governance and risk management. While they share some similarities, their objectives, scope, and approaches differ significantly. In this comprehensive overview, we will help you explore the process, objectives, and risks associated with both internal and external audits.

Internal Audit

Internal auditing is an independent, objective assurance and consulting activity designed to add value and improve an organisation’s operations. It helps accomplish objectives by bringing a systematic approach to evaluating and improving risk management, control, and governance processes.


• Risk assessment: the internal audit process begins with a thorough risk assessment of the organisation’s operations, processes, and controls. This assessment helps identify areas of potential risk and prioritise audit activities.
• Audit planning: based on the risk assessment, an annual audit plan is developed, outlining the scope, objectives, and timeline for each audit engagement.
• Fieldwork: Internal auditors conduct fieldwork, which involves gathering and analysing data, interviewing personnel, observing processes, and testing the effectiveness of internal controls.
• Reporting: After completing the fieldwork, internal auditors prepare a report detailing their findings, areas for improvement, and recommendations.
• Follow-up: the internal audit team follows up on the implementation of their recommendations and provides guidance to management on addressing any identified issues.


The primary objectives of an internal audit are:

• Internal auditors assess the adequacy and effectiveness of the organisation’s internal control systems, including operational, financial, and compliance controls.
• Internal audits help identify and mitigate risks that could impact the achievement of the organisation’s objectives.
• Internal auditors review processes and procedures to identify opportunities for improving operational efficiency and effectiveness.
• They ensure that the organisation complies with applicable laws, regulations, policies, and industry standards.


While internal audits play a crucial role in organisational governance and risk management, there are certain risks associated with the process:

• Internal auditors may face pressure from management or conflicts of interest, which could compromise their independence and objectivity.
• The scope of internal audits may be restricted due to resource constraints or management’s resistance to certain areas of review.
• Inadequate training, experience, or a lack of professional scepticism can undermine the effectiveness of internal audits.
• Failure to report findings accurately or a lack of follow-up on recommendations can diminish the value of internal audits.

External Audit

An external audit is an independent examination of an organisation’s financial statements and records by a qualified third-party auditor. Its primary objective is to provide an opinion on whether the financial statements fairly present the company’s financial position and results in accordance with applicable accounting standards.


• External auditors evaluate potential clients and assess the risks associated with accepting or continuing an audit engagement.
• The auditors develop an audit plan, which includes identifying significant risk areas, determining the nature and extent of the audit procedure, and allocating resources accordingly.
• External auditors assess the risks of material misstatements and evaluate the design and operating effectiveness of the client’s internal controls.
• External auditors perform substantive procedures, such as analytical procedures, tests of details, and other audit procedures, to obtain sufficient and appropriate audit evidence.
• Based on the audit findings, external auditors issue an auditor’s report, expressing an opinion on the fairness of the financial statements.
The primary objectives of an external audit are:

• The auditors provide an independent opinion on whether the financial statements present a fair and accurate view of the organisation’s financial position, results of operations, and cash flows.
• External auditors ensure that the financial statements comply with applicable accounting standards and regulatory requirements.
• External auditors evaluate the design and operating effectiveness of the organisation’s internal controls over financial reporting.
• External audits can help detect material misstatements due to fraud or error.
• In certain industries, external audits may be required to assess compliance with specific regulations or industry standards.


External audits are not without risks, and it is important to be aware of the following potential concerns:
• External auditors must maintain their independence and objectivity throughout the audit process. Factors such as personal relationships, non-audit services, and financial interests can threaten independence.
• External auditors may face scope limitations due to restrictions imposed by management, a lack of access to information, or other practical constraints.
• The quality of an external audit can be affected by factors such as auditor competence, professional scepticism, and adherence to auditing standards.
• External audits may not detect all instances of fraud or illegal acts, particularly if they are well-concealed or involve collusion.

Both internal and external audits play a crucial role in promoting transparency, accountability, and effective risk management within organizations. While their processes, objectives, and risks may differ, they complement each other in providing assurance and insights to stakeholders.
