The purpose of an internal audit is not to catch employees doing something wrong or to find fault with existing processes. Instead, it is a constructive process aimed at identifying areas for improvement and ensuring the organization is running efficiently and effectively, while also meeting compliance standards.

1. Define the Scope and Objectives

The first step is to clearly define the scope and objectives of the audit. This involves identifying the specific areas of your organization that will be under review. Is it a specific department, function, or process? Are there particular regulations or standards you need to adhere to?

For example, the scope could be defined as “evaluating the effectiveness of financial controls in the accounts payable department to ensure compliance with industry regulations.” Having a well-defined scope helps focus the audit and ensures all stakeholders understand the objectives.

Preparing for an internal audit is a collaborative effort, and you will need to assemble a diverse team with the right skills and knowledge. This team should include representatives from the areas being audited, as well as individuals with a thorough understanding of your organization’s processes and goals.

The team should be led by a qualified internal auditor or a senior member of staff with experience in audit preparation. This leader will be responsible for coordinating the efforts of the team and ensuring that the audit runs smoothly. It is essential that all team members understand their roles and responsibilities, and clear communication channels are established from the outset.

3. Create a Comprehensive Plan

Once the team is in place, develop a detailed plan of action. Start by reviewing the audit objectives and break them down into manageable tasks. Identify the specific documents, data, and information that will be required, and assign team members to gather and organize this material.

  • Week 1: Define scope and assemble team
  • Week 2: Develop and finalize the audit plan
  • Week 3: Gather and review relevant documents and data
  • Week 4: Identify and address any gaps or issues
  • Week 5: Finalize preparations and conduct a trial run
  • Week 6: Audit commencement

By setting clear milestones, you can ensure that the preparation process stays on track and that no important tasks are overlooked.

  • Be thorough: Ensure you provide a complete set of documents that cover all aspects of the audit scope.
  • Ensure accuracy: Verify the accuracy of the information provided. Outdated or incorrect data can lead to misleading conclusions.
  • Organize logically: Develop a filing system that makes sense to the audit team. Group documents by topic or function to aid understanding and speed up the review process.

5. Identify and Address Gaps or Issues

As you review your documentation and data, you may uncover gaps or areas of non-compliance. It is important to be proactive in addressing these issues before the audit commences. Identify any weaknesses in your processes and take steps to rectify them, implementing new controls or updating policies where necessary.

For example, if the audit scope includes reviewing health and safety procedures, and you discover that employee training records are not up to date, take immediate action to address this. Arrange for the necessary training to be conducted and ensure that records are accurately maintained going forward.

By identifying and resolving issues ahead of time, you demonstrate a commitment to continuous improvement and reduce the likelihood of unfavorable findings during the audit.

6. Finalize Preparations and Conduct a Trial Run

In the lead-up to the audit, it is beneficial to conduct a trial run or dry test. This involves walking through the audit process as if it were the real thing. It helps to identify any last-minute issues or oversights and ensures that your team is fully prepared for the actual audit.

During the trial run, pay attention to the following:

  • Are all the necessary documents readily accessible?
  • Are there any gaps in the information provided?
  • Are your team members familiar with the audit process and their roles?
  • Are there any logistical issues, such as room bookings or IT requirements, that need addressing?

By conducting this trial run, you can fine-tune your preparations and ensure that everything runs smoothly on the day of the audit.

7. Collaborate with the Auditors

Throughout the preparation process, maintain open lines of communication with the internal audit team. Collaborating with the auditors helps to ensure that your efforts are aligned with their expectations. They can provide valuable insights and guidance, ensuring that your preparations are on the right track.

Discuss the audit plan with them and seek clarification on any aspects that are unclear. Provide updates on your progress and highlight any concerns or challenges you have encountered. By fostering a collaborative relationship, you can avoid surprises during the audit and increase the likelihood of a positive outcome.

8. Learn from the Audit and Implement Improvements

The internal audit process does not end once the auditors have completed their assessment. It is important to view the audit as an opportunity for continuous improvement. Once you receive the audit report, carefully review the findings and recommendations.

Identify the areas where improvements can be made and develop an action plan to address them. Implement corrective measures and ensure that they are sustained over the long term. By doing so, you demonstrate the value of the audit process and contribute to the overall effectiveness of your organization.


Preparing for an internal audit is a detailed and complex process that requires careful planning and execution. By following the steps outlined in this article, you can approach the audit with confidence, knowing that you have taken the necessary steps to ensure a successful outcome.
