An audit is a systematic, independent, and documented process used to determine, through objective evidence, whether an organization complies with the criteria established by a standard, management system, or certification scheme.
Beyond verifying requirements, audits help identify strengths, detect nonconformities, and drive continuous improvement.
A business audit provides insight into the implementation and effectiveness of a management system. It goes beyond document reviews by examining how procedures are applied, analyzing records, interviewing relevant personnel, and verifying that actual practices align with applicable requirements.
Once the scope of the assessment has been defined, AENOR assigns the audit team and coordinates with the organization on the dates, sites, processes, and people who will participate. The audit plan sets out the agenda and applicable criteria, and allows the necessary documentation to be requested in advance.
Good preparation helps ensure that the assessment is organized, efficient, and proportionate to the complexity of the organization.
The audit begins with an opening meeting during which the team, objectives, scope, and methodology are presented. The auditors then collect and verify evidence through interviews, the review of documents and records, observation of activities, and sampling.
The evidence must be sufficient and verifiable to support the conclusions, regardless of whether the assessment is conducted on-site or entirely or partially remotely.
During the assessment, strengths, opportunities for improvement, and deviations or nonconformities against the audit criteria may be identified.
The audit team communicates the findings clearly and discusses them with the organization, avoiding ambiguous interpretations. Each conclusion must be supported by the evidence analyzed.
At the end of the assessment, the audit team holds a closing meeting to present the main conclusions. Subsequently, the organization receives an audit report outlining the scope, relevant evidence, and findings identified.
This document provides a clear basis for understanding the outcome of the assessment and defining the necessary actions.
If deviations are identified, the organization must analyze their causes and submit a corrective action plan within the established timeframe. The audit team reviews whether the proposed measures and the evidence provided are appropriate.
In certification processes, the final decision is made independently based on the audit information. This ensures that assessment and decision-making are kept as separate functions.
It assesses the implementation of the management system and its compliance with the reference standard before granting certification. In ISO 9001 audits, for example, it is analysed whether the quality management system is in place and effective within the requested scope.
Once the certificate has been granted, AENOR carries out annual follow-up audits to check that the system is properly maintained. Generally, a renewal audit is carried out every three years, with a more in-depth evaluation that allows the continuation of the certification to be decided.
In certain cases, it may be necessary to carry out an extraordinary audit to review specific aspects before making a decision. Its necessity and scope depend on the circumstances of the process and the applicable requirements.
Technology enables evidence gathering through remote methods while maintaining the same evaluation requirements. Remote audits use information and communication technologies to review documentation, conduct interviews, and observe activities and facilities.
Organizations should review the scope and applicable criteria, confirm the availability of responsible personnel and records, and ensure documentation accurately reflects actual operations.
An audit should not be viewed solely as an inspection. It is an opportunity to assess process robustness, recognize strengths, and identify improvements before issues have a greater impact.
Certification creates value when it is supported by a rigorous, transparent, and impartial audit process. AENOR's technical expertise and the traceability of every phase help ensure that conclusions are based on objective evidence.
