our procurement approach Our objective is to procure all materials, supplies and services, including those for which contracts and subcontracts are awarded or renewed, through the CSX Competitive Bid process. This process for supplier selection uses a team-oriented and cross-functional approach designed to maximize savings on a total cost basis. The CSX team will establish the goals and timeline of the project, conduct research and benchmarking, invite supplier input, accept supplier requests for Quotation (rFQs), conduct negotiations, and award the contract. The process also provides for periodic measurement and follow-up analysis. 4
