| Résumé : |
The coatings industry at all levels is becoming increasingly subject tu auditing by a variety of entities. The American Society for Quality (ASQ) defines an audit as a “systematic, independent and documented process for obtaining audit evidence (records, statements of fact or other information which are relevant and verifiable) and evaluating it objectively to determine the extent to which the audit criteria (set of policies, procedures or requirements) are fulfilled."
Audits are performed by certification organizations such as SSPC Qualification Procedures(QP),the NACE International Institute Contractor Accreditation Program (NIICAP), ASIC Sophisticated Endorsement for Fabrication or Painting (AISC SPE 420) or against various International Standards Organization (ISO) programs for laboratory analysis, calibration and quality. Work related to nuclear work generally involves auditing against 40 CFR 50, Appendix B or ASME NQA-I standard, "Quality Assurance Requirements for Nuclear Facility Applications." Many large manufacturing or construction projects also perform supplier audits on current and potential vendors or contractors.
Audits should also be internal and ongoing. These internal audits are generally performed on processes, employees, procedures and other functions used to control quality. SSPC's QP programs require an annual internal audit.
So, you got audited, or performed an internal audit of your own company. Obviously, there were some findings. Now what ?
Requests for correcting nonconformities or findings commonly result from any type of audit. Corrective action is action taken to eliminate the causes of the nonconformity, defect or other situation in order to prevent recurrence. Corrective action is reactive and is about eliminating the cause of a current problem. Preventive action is action taken to eliminate the causes of future issues— a proactive approach.
Most corrective actions fait because they treat the symptoms or perceived symptoms, but never address the cause. Addressing the symptoms instead of the cause leads to a temporaty or partial fix. For example, if you have high dry-film thickness (DFT) readings and only correct if by reducing the applied DFT to resolve that single problem, you may not learn why the DFT readings were high in the first place. Maybe the Bauges weren't calibrated properly, leading to inaccurate readings, or perhaps the applicators did not receive adequate training in the equipment and methods they were using. This is where root cause analysis comes in handy. |
