Managing Automotive Electronics Suppliers: Connecting Drawings, BOMs, and Design Changes with PLM
For electronics and automotive electronics manufacturers to work with suppliers from the same product baseline, this guide outlines the information and change procedures to manage in PLM.
Supplier management does not end with sending the latest files
If the customer and supplier work from different drawings or BOMs, missed changes and rework may occur. You must manage together which revision applies to which product and from when, who approved it, and whether the supplier has confirmed it.
PLM connects product lifecycle information
PLM (Product Lifecycle Management) is an approach to managing information across the product lifecycle, including planning, design, and changes. It is designed to connect drawing and document versions, part and BOM relationships, and review and approval histories so that product baselines can be shared. The scope of management is defined by connecting related operations, such as SCM, for supplier purchasing, delivery, and inventory areas.
Flows to Review in the Automotive Electronics Supply Chain
Review the sequence: design change request → identify affected parts, products, and suppliers → review and approval → confirm the effective date → distribute to suppliers and confirm receipt → reflect in purchasing and production baselines. The actual approval stages and responsible parties are determined according to the customer's operating procedures.
Define Disclosure Scope and Operational Responsibilities First
Separate the drawings and documents each supplier may access, and distinguish pre-approval materials from final distribution materials. Also define how to handle remaining inventory and work in progress after a change. The mere adoption of PLM does not automatically guarantee compliance with customer requirements or quality specifications.
Scope to Review with CMC TECH
CMC-PLM application scope is reviewed based on your current drawing and BOM management methods, the number and roles of suppliers, the design change approval process, and the master data criteria to connect with ERP and MES. For an initial consultation, you may explain using an anonymized workflow and requirements instead of actual confidential drawings.
