Before suppliers are specified, an assessment of the QM system (certification / auditing) must be obtained.
Evidence must be provided of the timely planning for selecting and assessing new suppliers, based on selection criteria meeting the customer's project plan.
For serial production it must be ensured that only suitable suppliers are used.
If there are deviations from the organisation's own selection criteria, the further procedure must be decided on. Experience from evaluations of quality performance assessments must be taken into account for existing suppliers.
Risks in the supply chain must be determined and assessed and must be reduced by appropriate action (strategy for emergencies)
Process audits or comparable methods must be planned and executed in all phases for the suppliers selected (depending on the risk classification of the product).
It must be ensured that the suppliers have sufficient capacities – this also applies to changes in quantities.
