An auditor can ask about monitoring resources by inquiring how the organization determines and provides the necessary resources to ensure valid and reliable results to verify the conformity of products and services. They may also ask how the organization ensures that the monitoring and measuring resources provided are maintained, what records are retained to evidence that the resources are properly maintained, which standards are followed for the calibration or verification of measuring equipment, how the organization safeguards its measuring equipment, and what actions are taken when measuring equipment is found unfit for its intended purpose.
