Currently we review non-conformance's raised for Out of Spec Product etc, however should there be more to this section.
In order to review process performances you need to establish KPIs (Key Performance Indicators) for processes, meaning that you need to determine some indicator that can tell you weather your process is working in desired way and if it delivers intended results. For example for warehousing or storage process the number of nonconforming products in storage can be the indicator of storage process performance.
The same is for product conformance, you need to inspect the product against the product requirements and if there are nonconformities, to resolve them with corrective actions. Records of such nonconformities should be reviewed during the management review and the management should make decisions to remove those nonconformities in the future.
Beside nonconformances related to Out of Spec Product you should keep track of all nonconformities in your company in order to have more data to review and make decisions to prevent them from happening in the future. In this way you will truly improve your QMS and your company.
