Why use an internal audit checklist?

The purpose of internal audit checklist is to help monitor and evaluate the conformance of an organization’s quality management system and the effectiveness of its processes. By using the internal audit checklist to compare business activities to broad system requirements, you can ensure that each clause or requirement has been assessed.

  • Use the audit checklists to capture management system conformance;
  • Manage your audit findings in real-time;
  • Filter the audit checklist to select specific clauses to assist with process auditing;
  • Generate charts to summarize, communicate and report your internal audit findings.

How do I audit a process?

Effective process auditing requires the auditor to identify and record audit trails that will make a difference to the business. Once your management system has matured, businesses should develop a process approach to their internal auditing programme in order to verify that individual management system processes are performing and producing outputs in accordance with the planned outcomes.

Use the process audit template, which replicates the turtle diagram from the internal audit procedure, to encourage the auditors to review the inputs, outputs, risks, controls, activities, equipment, materials, personnel and methods of measurement for all processes, activities and shifts.

The process audit does not assess all aspects of the management system at once. It instead relies on sampling the applicable requirements and reviewing operating procedures, work instructions, contracts, policies, plans, organization charts, flow charts, etc., including the linkages among these documents to determine effectiveness.

How do you conduct an ISO 9001 audit?

Use the fully editable internal audit checklists to help ensure that each clause is assessed, and that your processes are delivering the expected outputs. Completing the audit checklists and questionnaires encourages involvement and auditee participation whilst ensuring transparent conduct.

ISO 9001 internal audit checklist

System audits are commonly referred to as a ‘first-party audit’ and are conducted by businesses to determine conformance to a set of audit criteria arising from standards like ISO 9001:2015, often in preparation for certification.

The Internal Audit Checklist focuses on the quality management system requirements to ensure that each clause has been implemented. The internal audit checklist may be used for requirement audits initially and then filtered for ongoing process auditing.

Process audit checklist

The adoption of the ‘process approach’ is mandated by ISO 9001:2015 and is one of the most important concepts relating to your quality management system. You can use the Process Audit Checklist Template for conducting an in-depth analysis to to review and verify the inputs, outputs, risks, controls, activities, equipment, materials, personnel and methods of measurement for each process.

Supplier audit checklist

When evaluating and selecting suppliers, supplier audits are often conducted to verify that the potential supplier has an adequate management system that can ensure consistent performance in delivering conforming products, parts or services.

Use the off-site supplier self-evaluation questionnaire to initially gather this information. Based on risk and other priorities, use the on-site supplier Audit Checklist to undertake a more detailed, 2nd party; follow-up audit.
