An audit is a thorough examination of financial records, operations, or processes conducted independently to verify accuracy, balance, and compliance with enacted legislation, standards, and internal policies. It seeks transparency, accountability, and general confidence between stakeholders like investors, regulators, and management. An audit may take the form of an internal or external process, each for different purposes: Internal auditing aims at enhancing internal control and managing risks, while external auditing is normally focused on obtaining an independent appraisal of the truth and fairness of financial statements.
Auditing serves to identify errors, fraud, and inefficiencies within an organisation. Audit serves as a decision-making tool, providing stakeholders with reliable financial information. Audits have gone beyond the financial matters to operations, compliance, and environmental matters owing to increased regulatory pressures and the complexity of business matters.
Generally, these phases include planning, collecting evidence, assessing internal control, and reporting. Auditors are bound by ethics and should always apply professional skepticism and the reasonable use of professional judgment. Through this, they provide credibility and viability to organisations and institutions. Auditing is, in the end, a cornerstone of good governance and prudent fiscal management, which instills confidence in organisations.
What is an ISO Audit?
ISO audit is an organised and unbiased assessment that gauges the level at which activities of an organisation align with the requirements of a particular ISO (International Organisation for Standardisation) standard. ISO audits are crucial for organisations going for certification or conformity validation with standards such as ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 27001 (Information Security Management).
The primary aim of an ISO audit is to measure the effectiveness of a management system, track continuous improvement, and determine compliance with set procedures. ISO audits are traditionally classified into three types: first party (internal), second party (customer), and third party (performed by external certifying bodies).
During the course of auditing, the auditor reviews documents, conducts interviews with employees, and carries out walk-throughs to ensure that they are complying with ISO standards. Findings are presented in an audit report, which gives details of areas of compliance, noncompliance, and opportunities for improvement.
ISO auditing allows businesses to become more operationally efficient, reduce risk, meet customer needs, and have a better global reputation. An effective ISO audit is evidence of commitment to quality, conformity, and continuous improvement.
Types of ISO Audit
ISO audits are grouped based on their purpose and the organisation conducting them. All ISO audits play a vital role in enhancing quality, compliance, and building trust in organisational systems.
1. Internal Audit (First Party Audit)
This type of audit is done in-house by the organisation or by trained internal auditors. The primary reason is to evaluate the organisation’s internal management systems and check for continuous compliance with ISO standards. It assists in determining areas that should be improved, in readiness for external audits, and in the maintenance of ongoing conformity to set standards.
- Purpose: self-assessment and preparation.
- Conducted by internal auditors.
- Outcome: A report to the internal organization with suggestions for improvement.
2. Second Party Audit (Supplier Audit)
Second-party audit refers to an audit carried out by an organisation against its suppliers or contractors to ensure that the products or services comply with specified requirements. These audits determine if the supplier is following certain ISO standards or contractual terms.
- Purpose: To evaluate vendors or suppliers.
- Conducted by the client or customer organisation.
- Outcome: Approval of supplier, monitoring, or contract decisions.
3. Third-Party Audit (Certification Audit)
Third-party audits, performed by a selfless external certifying organization, are required for official ISO certification. These audits ensure that an organization’s management system adheres to all requirements of a particular ISO standard.
- Purpose: Certification or recertification.
- Conducted by accredited certifying bodies.
- Outcome: Certification decision and public acknowledgment.
How is an ISO Audit Conducted?
ISO audit applies a systematic and methodical process to identify whether an enterprise is conforming to the standards of a specific ISO standard. The methodical process leads to full examination, ongoing improvement, and compliance with international standards.
1. Audit Planning
Audit planning is the first step in the audit process, defining the scope, objective, and audit criteria. Auditor reviews documents relevant to the audit, such as manuals, procedures, and past audit reports. An audit plan is formulated, indicating the time period, places of audits, and which members of the team will be engaged.
2. Opening Meeting
The audit procedure starts with a meeting of introduction between the auditor(s) and the organization’s management. The meeting is meant to confirm the audit plan, explain the audit procedure, and open communication channels.
3. Audit Conduct (On-Site or Remote)
The auditor begins conducting the examination of processes, records, and systems of the organisation to check for their compliance with ISO standards. The process involves examining documentation (e.g., policies, procedures, and training records), interviewing employees from different levels, and witnessing operations and processes in real time.
The auditor collects objective facts to determine whether the system is implemented and maintained effectively.
4. Identification of findings
Auditors report areas of compliance, non-compliance, and areas of improvement. Non-compliances are classified according to severity (major or minor) and must have corrective actions implemented.
5. Closing Meeting
There is a closing meeting where the findings are presented to the management. The organisation is given an opportunity to rectify any findings and set out subsequent action.
6. Audit Report and Follow-Up
An extensive audit report is issued that summarises the findings. In case any non-compliances are found, corrective actions must be taken by the organisation and supporting evidence of the resolution submitted. Successful certification audits result in ISO certification or continued certification status.
ISO Audit Checklist
An ISO audit checklist is a detailed tool utilised by auditors to enhance and document their assessment of an organisation’s conformity with a particular ISO standard. It provides for a standardised, orderly, and thorough auditing process. The checklist typically includes questions, requirements, and evidence based on the related provisions of the applicable ISO standard (e.g., ISO 9001, ISO 14001, ISO 27001). A proper ISO audit checklist is required to determine a total, equitable, and unbiased analysis of a management system.
1. Context of the Organisation
- Are internal and external issues related to the purpose of the organization identified?
- Are the expectations and needs of interested parties recorded?
- Is the extent of the management system defined?
2. Leadership
- Is there evidence of top management commitment to the management system?
- Are duties, tasks, and authority well defined and communicated?
- Is a quality/environmental/information security policy established, communicated, and implemented?
3. Planning
- Are opportunities and risks identified and controlled?
- Are there clear objectives in accordance with the policy?
- Is there a plan that has been established for these objectives, including resources and responsibilities assigned to them?
4. Support
- Are appropriate resources available for the system?
- Is personnel competence defined, kept up to date, and evidenced?
- Is organisational communication effective?
- Are the recorded information and controls adequately maintained and up to date?
5. Operation
- Are operational procedures designed, implemented, and controlled?
- Are product/service requirements defined and periodically reviewed?
- Is there monitoring of outsourced processes and suppliers?
- Do operational changes follow a systematic process?
6. Performance Evaluation
- Are monitoring and measurement activities defined and implemented?
- Is regular and effective internal auditing conducted?
- Are management reviews held, and do they consider the performance of the system?
7. Improvement
- Are non-conformities detected and corrective measures implemented?
- Is continuous improvement of the system being sought?
Tips To Prepare For An ISO Audit
Preparation for an ISO audit calls for a sound strategy so that your company is compliant with the requirements of the standard and prepared to demonstrate compliance. Following these suggestions will allow your company to approach an ISO audit with confidence, reduce disruption, and demonstrate high-quality compliance and continuous improvement.
- Get familiar with the requirements of the under review ISO standard (e.g., ISO 9001, ISO 14001, ISO 27001). Ensure that essential staff are informed of their roles to meet the needs of the standard.
- Conduct a gap analysis to assess existing practice against the standard. Determine areas of improvement or corrective actions before the formal audit.
- Read the documentation carefully. Ensure all documentation required is current, accurate, and easily accessible. Typical documents are information security policies, environmental and quality policies, procedures, work instructions, risk analysis, and mitigation controls. Internal audits and documented management reviews.
- Perform internal audits on a regular basis to identify and correct non-conformities. Have the findings discussed with corrective actions and documented properly.
- Prepare and train employees. Inform employees of the ISO standard and auditing process. Make sure employees understand procedures to be followed and can explain their roles to auditors.
- Perform a Mock Audit, a trial audit, or a dry run to replicate the real audit. Expose weak points in a low-pressure setting and build confidence.
- Process Non-Conformities. Check implementation and validation of corrective actions on the basis of previous audit outcomes.
- Ensure clear and organised documents. Ensure that every document and evidence is properly organised and trackable. Auditors will expect to see documented evidence of ISO conformity.
- Prepare for opening and closing Meetings. Prepare to talk about your management system, goals, and performance. Designate roles for leading the discussion and answering audit questions.
- Encourage employees to look at audits as an improvement process with a positive intent, as opposed to a punitive action. Foster transparency, honesty, and professionalism during the auditing process.
Conclusion
An ISO audit checklist is a valuable tool to ensure proper and consistent evaluation of compliance with ISO. It helps auditors review vital processes, detect non-conformities, and encourage continued improvement, thus strengthening an organisation’s commitment to quality, effectiveness, and regulatory compliance.
