The debate around the “Part Proxy” concept, introduced by Prof. Dr. Jörg W. Fischer, highlights challenges in managing interchangeable parts across different plants in manufacturing. It emphasizes the need for proper identification and interchangeability criteria, advocating for distinct part numbers when constructions differ, while maintaining a system for equivalent items to ensure clarity in manufacturing processes and documentation.
Prof. Dr. Jörg W. Fischer sparked a debate on the relevance of Form-Fit-Function (FFF), suggesting it is gradually losing significance. FFF’s misuse and complexity in modern systems necessitate a cross-functional approach for effective impact assessments. While FFF remains valuable, its application must adapt to evolving requirements and increased complexity in product design.
Changing a part’s traceability level, like transitioning from non-serialized to serialized, may necessitate a new part number. This depends on the physical label’s requirements, which might alter the part’s form but generally not its fit. However, the transition impacts the part’s functionality, ensuring better traceability throughout its lifecycle.
