Customer-specific requirement (CSR) is very important for the IATF 16949: 2016 standard. The standard requires customer-specific requirements (CSR) to be evaluated and adapted to the quality management system.
1. CSRs should be read, and additional expectations should be indicated in a table. The table can be in any format you want. The table should show a match with the special requirement and documents in your quality management system.
2. Special requirements contained in CSRs should be mentioned in Quality management documentation such as the relevant process, procedure, instruction, and/or quality manual.
3. Of course, the relevant process owners should be knowledgeable and trained about these special requests. For example, one special requirement of VW is to make a process according to VDA 6.3. In summary, this requirement should be shown in the table, it should be matched with your QMS document, this requirement should be input into the relevant document. You should use the VDA 6.3 format for internal audit reports and your internal auditors should be VDA 6.3 certified.
After reviewing the CSRs, it is also important to document an action plan about the issues you cannot comply with. This means that the CSR has been reviewed by the organization and there is awareness. Open actions should be completed as soon as possible.
