10 SAP Ariba experts
SAP Ariba work here is seen from inside operating companies: administrators, application leads and program managers at companies such as Entegris, Georgia-Pacific LLC, The AES Corporation and INA Grupa, whose titles and work name buying and invoicing, sourcing and contracts, SLP and Ariba Network enablement. A procurement or IT leader deciding who should own Ariba after go-live, or how to get suppliers onto the network, hears from people who did that work in-house.
