VDA Maturity level assurance for new parts. Methods, measurement criteria, documentation. 3rd, revised edition, June 2022

Anotácia textu normy:

This VDA publication focuses on a comprehensive and consistent presentation of maturity levels within the framework of progress in a project covering new parts, combined with an assessment of the maturity of the product and manufacturing process at agreed times within the product creation process. The maturity level assurance method can be applied both in internal customer-supplier relationships (within an organization, e.g. groups of companies) and in external customer-supplier relationships (between an organization and its customer or between the organization and its supplier). A significant element is therefore the rules covering cooperation at all stages in the supply chain, with the integration of all those involved in the project. To this end, important customer-supplier relationships are defined within the framework of milestone assessments in projects (new projects, face-lifts or other modification projects initiated by the customer), a concrete cooperation model in the project is described and thus the early, cross-functional integration of all those involved is assured.
