As part of the tire maker's broader strategic initiative to improve global procurement operations, increase visibility into company spend, and drive contract compliance, Goodyear has selected Ariba(R) Contracts(TM) to more efficiently track enterprise-wide spend against contract.

The transformation of our global contracts process will allow us to increase the efficiency of Goodyear's spend management process and achieve our cost savings goals."
