Published on: April 24, 2023

As a Management System Internal Auditor, starting out can be both exciting and daunting. You may find yourself faced with new challenges and responsibilities as you navigate the world of auditing. But fear not! In this blog, we’ve got you covered with 7 essential tips to help you kickstart your career as a Management System Internal Auditor with confidence.

Have you completed training to become a Management System Internal Auditor, but are yet to actually conduct an Internal Audit on your own? If you answered yes, you’re not alone, as many new auditors struggle to initiate the process.

After speaking with some of our students, we found that the main struggle with getting started is due to a lack of confidence, feeling the need to gain more experience, or uncertainty about where to begin. To assist you in starting, we have 7 straightforward tips that can assist you in breaking down what appears to be a challenging task, into more manageable steps.

Let’s get into it:

1. Know the ISO Management System Standards you’re auditing against

Before conducting Internal Audits, it’s important to familiarise yourself with the relevant ISO Management System Standard(s). This includes reading and interpreting the standard’s requirements, understanding the scope and purpose of the standard’s clauses, and familiarising yourself with the key terms and definitions used in the standard. Knowing the ISO Standards you are auditing against is crucial for ensuring conformance, enhancing credibility, maintaining consistency, delivering value-added audits, and promoting your knowledge and professionalism.

Listed below are the four main ISO Management System Standards:

2. Develop an Audit Plan

An audit plan is essential to ensure that the audit is focused, efficient, and effective. Start by identifying the scope, objectives, and criteria for the audit. Identify the resources required, define a timeframe, and communicate the audit plan to relevant stakeholders. Make sure to consider the organisation’s operational requirements when planning the audit.
3. Take a Process Approach

The ISO Management System Standards require that audits are conducted against the organisation’s own processes, as well as against the requirements of the relevant ISO Standard(s). It’s vital to use a structured process to conduct the Internal Audit, and auditing via the organisation’s processes (with references back to the related clauses of the standard(s)) ensures a meaningful process which facilitates continual improvement. This approach ensures that the audit is comprehensive and that all relevant areas are covered.

4. Communicate effectively

As an Internal Auditor, effective communication is key. You need to communicate with auditees, sometimes other auditors, and other stakeholders throughout the audit process. Be clear, concise, and objective in your communication. Ask open-ended questions to gather relevant information, listen actively to understand the auditee’s perspective, and provide feedback in a professional and constructive manner.

5. Be Objective and Unbiased

Internal Audits should be objective and thorough, and not just a box-ticking exercise. To maintain objectivity, it’s best to audit an area of the organisation in which you are not directly involved. As an auditor, you should be rigorous in your assessment and provide evidence-based analysis and feedback. Be sure to document all findings, including any non-conformances, observations, and opportunities for improvement.

6. Use effective audit techniques

Utilise appropriate audit techniques during your audits. Conduct interviews, and document reviews and observations to gather evidence. Use sampling techniques to efficiently assess the conformance of processes and practices with the organisation’s own requirements and the ISO Standards. Take comprehensive notes during audits, and ensure that your findings are well-documented.
7. Continually improve your skills

Internal Auditing is a continual learning process. Seek feedback from auditees and colleagues to improve your auditing skills. Stay updated with the latest changes in the ISO Management System Standards and best practices in Internal Auditing. It’s important to strive to enhance your knowledge, skills, and competence as an Internal Auditor.
