1. Quotation-to-PO pipeline (BOM → award → PO)
Sourcing electronic components for a complex PCBA is not merely an administrative task of matching Manufacturer Part Numbers (MPNs) on a spreadsheet. The quotation and procurement pipeline is a rigorous engineering and commercial process. It must systematically validate component lifecycles, proactively identify sole-source risks, and secure appropriate, volume-based pricing.
We define the structured workflow from the initial ingestion of a customer’s raw Bill of Materials (BOM) to the final issuance of a Purchase Order (PO) to the supplier. This chapter establishes the protocols for managing Approved Vendor Lists (AVL), navigating global allocation constraints, and locking in reliable lead times to guarantee material availability before the production line starts.
