Quality Manual
Section 8.5 — Production and service provision
The organization carries out production and service provision under controlled conditions. Controlled conditions include the availability of documented information defining the characteristics of the products and the results to be achieved, suitable monitoring and measuring resources, and the use of competent people.
Identification and traceability
Outputs are identified by suitable means throughout production and service provision, and their status with respect to monitoring and measurement requirements is identified. Where traceability is a requirement, the organization controls the unique identification of outputs and retains the documented information needed to maintain traceability.
Release of products and services
Planned arrangements are completed satisfactorily before release, and the release of products and services to the customer does not proceed until then, unless otherwise approved by a relevant authority. Documented information provides traceability to the person authorizing release.

What is an Internal Audit Checklist?
An internal audit checklist is a structured tool that auditors use during management system audits to systematically verify whether an organisation complies with the requirements of an ISO standard. Rather than relying on memory or ad-hoc questioning, a well-designed checklist guides the auditor through every relevant clause, ensuring a thorough and repeatable assessment each time.
Using a checklist during internal audits delivers three key benefits: it ensures nothing is missed by providing a complete list of requirements to verify, it creates a consistent audit approach so that different auditors achieve comparable results, and it produces a documented evidence trail that satisfies both management review and external certification body expectations.
What's Included in Our Checklist
- Clause-by-clause audit questions aligned to ISO 9001:2015
- Compliance, non-compliance, and observation rating columns for each question
- Dedicated space for recording objective evidence notes alongside each finding
- Nonconformity classification fields covering major, minor, and observation categories
- Corrective action tracking section with responsibility assignment and target dates
- Auditor and auditee signature fields for formal sign-off of audit results
How to Use an Internal Audit Checklist
- Plan the audit scope — define which processes, departments, and clauses will be assessed during this particular audit
- Review previous findings — check earlier audit reports and open corrective actions so you can verify whether issues have been resolved
- Work through each clause systematically — follow the checklist from start to finish, asking questions and gathering evidence at each step
- Record objective evidence — note the documents reviewed, records inspected, and observations made as proof of conformity or nonconformity
- Classify findings — determine whether each result is a major nonconformity, minor nonconformity, observation, or opportunity for improvement
- Agree corrective actions — discuss findings with the auditee, agree on root cause analysis, and set deadlines for resolution
- Follow up — verify that corrective actions have been implemented effectively and close out findings once evidence is satisfactory
