DIAGNOSIS:

  • Second most important point to be noted that, there are total five (5) “shall” word are used.
Understanding meaning of Rework I always preferred to refer ISO9000:2015 to understand any definition or explanation of word w.r.t ISO. Here to know about “rework” we will see clause 3.12.8 in ISO9000:2015. Rework: Action on a nonconforming (3.6.9) product (3.7.6) or service (3.7.7) to make it conform to the requirements (3.6.4). Processing the product, in such a way, that assures compliance of the product with requirement of stated technical delivery condition (TDC), drawings and / or specifications. Example of Rework: Some parts after machining found that thickness is more than what is required, so to make parts as per requirement, again machined and required thickness achieve. Meaning of clause 8.7.1.4 line by line: 1) The organization shall utilize risk analysis (such as FMEA) methodology to assess risk in the rework process prior to a decision to rework the product.
