Steps of Internal Audit

The internal audit engagement goes through a set of organized stages, the details of which vary according to the nature of the engagement and the size of the organization.

1. Planning

The engagement begins by determining the objective, scope, and area to be examined, with an understanding of the nature of the activity, processes, and associated risks.

2. Risk Assessment

Key risks that may affect the achievement of the objectives of the process or department under audit are identified.

3. Preparing the Audit Program

Testing procedures, required evidence, samples, and documents to be examined are determined.

4. Performing Audit Procedures

The audit team collects evidence, analyzes data, examines documents, and conducts necessary interviews and tests.

5. Analyzing Results

Results are compared with established policies, procedures, standards, and objectives, then deficiencies and risks are identified.

6. Preparing the Report

Audit results are presented in a report containing observations, impacts, and recommendations, according to the nature of the engagement.

7. Follow-up

Implementation of recommendations is monitored, ensuring that appropriate corrective actions are taken and identified observations are addressed.

What are the Tools of Internal Audit?

The internal auditor uses a variety of tools and methods to gather evidence and analyze processes, the most prominent of which include:

• Document examination: Reviewing contracts, invoices, records, and documents.
• Interviews: Obtaining information from employees and officials.
• Observation: Directly monitoring the implementation of processes.
• Sampling tests: Examining a sample of transactions instead of reviewing all transactions when appropriate.
• Data analysis: Using data to identify patterns and exceptions.
• Control tests: Assessing whether controls are operating as designed.
• Comparison: Comparing results with approved indicators, objectives, and policies.

What is Meant by Risk and Control in Internal Audit?

The relationship between risk and control is one of the most important internal audit fundamentals. 

Risks are events or circumstances that may negatively affect the organization’s ability to achieve its objectives, while controls represent the procedures and policies put in place to address these risks and mitigate their effects.

For example, if there is a risk of unauthorized access to data, one of the controls used may be implementing multi-factor authentication and periodically defining and reviewing user permissions.

The internal auditor assesses whether controls are appropriate for the risks and whether they are operating effectively.

How Does Internal Audit Contribute to Improving Company Performance?

Internal audit can transform from a function focused on error detection to an important partner in performance improvement when it relies on risk assessment and provides practical, actionable recommendations.

For example, the audit may reveal unnecessary steps in a process, weaknesses in the distribution of authorities, delays in transaction processing, or a lack of certain controls. By providing appropriate recommendations, management can improve the process, reduce risks, and raise efficiency.
