The supply manager should use E-RFx in this instance. E-RFx refers to electronic Request for Information (RFI), Request for Proposal (RFP), and Request for Quotation (RFQ). This process allows the supply manager to gather detailed information about the suppliers' capabilities, ensuring that they have the technology and capacity to recreate the obsolete custom component before moving forward with bidding. E-RFx helps in evaluating suppliers based on various criteria, including technical capabilities, financial stability, and past performance, providing a comprehensive understanding of each potential supplier.
