In any organisation, you need to make sure things are running as planned.

Operations need to be in order and operators need to be following the system and processes that are in place.

To ensure compliance within these operations, you need to technique to police them. This is were internal audits come in.

Think of an internal audit like a health check-up for a company.

A team (typically quality teams and business improvement personnel) reviews how things are being done. This will include checking regulations and procedures to spot where process inefficiencies, problems or operational risks may exist.

Proper documentation and communication will then allow these ‘auditors’ to inform relevant personnel on what’s working well and what needs fixing.

This helps an organisation stay compliant, efficient and on track, by following the processes and guidelines that allows it to work effectively.

Internal audits play a vital role when you roll out new processes or investigate recent failures.

By objectively reviewing how those processes were designed and executed, auditors can pinpoint weak spots, gaps in training, or control and contain breakdowns before small issues become big problems.

Internal audit insights help you fine‑tune new workflows for smoother launches and more effective initiation phases.

Additionally, you an quickly diagnose what went wrong in failed processes. With these internal investigations, you can transform defect and faulty processes, into sustainable and effective systems.

Let’s break down the key functions of Internal Audits, and why they are essential to any type of business.

Risk Management

Think of auditors as your business’s early-warning system.

They help you spot and keep an eye on anything that could go wrong. Whether it’s money, operations, rules, or big-picture strategy, risks need to be managed within your systems.

By checking how your risk controls are set up and actually working, you can catch potential issues before they become crises.

Reviewing Operational Efficiency

Auditors dive into your daily routines. For example, buying supplies, making products or supporting customers. These reviews priotise the identification of process inefficiencies.

From these finding, they can suggest improvements that can speed things up, cut out waste, and save money, so your team can work smarter, not harder.

Corporate Governance

Good governance is all about clear roles and honest decision‑making.

Internal audit takes a step back and checks if leaders are following making decisions that align with the standards and policies that infrastructure of the company is build upon.

This transparency makes sure everyone’s on the same page.

Testing Internal‑Control Effectiveness

Controls are your safety nets—think approval chains, account checks, or locked‑down systems. They prevent mistakes and fraud.

Auditors actually test these nets to see if they hold up. If they find holes, they’ll point them out so you can patch things up. It is important that internal auditors integrate these systems with an outside eye, with a non-bias perspective.

Ensuring Compliance

Rules matter—whether they’re laws, industry standards, or your own company policies. Internal audit reviews your licenses, reports, and procedures to make sure you’re playing by the book.

If something’s off, they’ll flag it and help you fix it before it snowballs into fines or bad press. Within any industry, making sure you are legally compliant is a necessity that can only be ensured by continuous monitoring.

Though each organization tailors its audit program to its size, industry and specific objectives, most internal audits consist of the following core phases.

Planning & Risk Assessment

First, an auditors will work with management and other relevant parties, to nail down exactly what’s being audited and what they hope to achieve. Whether that’s spotting compliance issues, uncovering inefficiencies, or something else.

Then they dive into the business: studying strategies, structures, policies, systems, and past audit reports to get the full picture.

Next comes risk assessments, think heat maps and risk matrices, techniques that will help identify and rank the most critical financial, operational, regulatory, and reputational risks.

With all that in hand, they draw up a detailed audit plan, laying out the who, what, when, and how.

Fieldwork & Evidence Gathering

Out in the field, auditors roll up their sleeves. They walk through processes with the people in charge, asking questions and mapping every step.

They test controls to make sure they’re both present and working as intended. This can include techniques like sampling invoices, querying system data, observing processes in action, or re-doing reconciliations themselves.

On top of that, they run analytical checks analysing trends within this data, to sniff out anything that doesn’t add up.

Evaluation & Analysis

Now it’s time to connect the dots. Auditors look at how well existing controls tackle the risks they uncovered, and estimate what could go wrong if those controls fail. This will include variables such as financial losses, regulatory penalties, or reputational harm.

From there, they craft recommendations with straightforward, prioritized fixes like tightening approvals, automating key checks, or refreshing policies to plug the gaps.

An effective auditor will do this by collaborating with relevant and specialist personnel depending on the improvements required.

Reporting

Auditors then put everything into a draft report: scope, methods, observations, risk ratings, causes, and suggested fixes.

They sit down with management to review it—capturing their feedback, agreed-upon action plans, and timelines.

Finally, they polish the report, add an executive summary, and hand it over to the audit committee or board so leadership can see what’s going on.

Follow‑Up & Monitoring

The job isn’t done once the report is out. Auditors track each issue in a findings log, keeping an eye on management’s progress against their action plans.

For high-risk items, they’ll circle back and re-test controls to ensure changes have actually been made. Once everything checks out, they formally close the findings and update the audit status.

Continuous Improvement

After wrapping up, the audit team reflects on how they did—looking at fieldwork efficiency, report clarity, and stakeholder feedback—to sharpen their approach next time.

Meanwhile, they keep the organization’s risk register up to date, factoring in new regulations, business shifts, or emerging tech, so the next year’s audit plan tackles the most relevant challenges.

Summary

When conducting Internal Audits you should focus on:

• Scope: Defining which areas, processes, systems or activities will be examined.

• Risk: Identifying and assessing the principal risks (financial, operational, compliance, reputational) within that scope.

• Procedure: Establishing and following a structured work program—tests of controls, transaction sampling, walkthroughs, re‑performance, data analysis to gather evidence.

• Testing: Verifying both the design and operating effectiveness of controls through sampling, observation, system queries and analytic reviews.

• Interview: Conducting discussions with process owners and staff to understand workflows, controls and potential gaps.

• Record: Examining documentation including policies, reconciliations, approvals and logs. In order to substantiate that controls are in place and operating.

• System: Leveraging or reviewing IT applications and reporting tools that support or enforce key controls.

• Communication: Keeping stakeholders informed throughout, by sharing plans, preliminary findings and final reports with management and other relevant personnel.

Together, these elements form a comprehensive internal audit cycle: from defining what to audit, through gathering and testing evidence, to reporting findings and staying connected with the organization’s people and systems.

By utilising these elements your organisation will thrive with great operational efficiency via exceptional internal process control, in a risk averse and compliant environment.
