4 AT&T SCM: Architecture highlights Oracle E-Business Suite Centric Scale-up with cluster database on very large infrastructure High availability with Oracle Data Guard, Oracle GoldenGate, and site level redundancy Central inventory/financial management; utilizes product hub, planning/forecast with ASCP/Demantra Order orchestration and brokering with in-house developed Oracle based application system Internet deployment for interaction with external suppliers Management reporting/profitability analysis; procurement and spend analytics Industry leading warehouse/distribution management systems

5 AT&T SCM Platform: Financial Integration Both Network and Retail SCM - financial counterparts are integrated in the same platform: Shared AP, AR, PA, FA, and GL Supply Chain transactions leverage same referential data and accounting rules Financial integration of supply chain transactions are seamless and are recorded real-time in the general ledger No need for reconciliation between sub ledgers Ability to forecast financial implications based on SCM forecasts Online financial budgeting validation on purchasing and requisitions Analytical GL Cube and Inventory Cube

6 Results AT&T has saved more than $500 million and has improved its purchasing power by combining accounts with its vendors.
