DESCRIPTION
Organizations today often face similar challenges and concerns when developing and implementing an automation framework in an SAP environment. These include: timely regression testing to address SAP support packs, lack of expertise, aggressive target dates, technical challenges unique to SAP, decentralized IT resources and assets, and a poor (or non-existent) baseline test library. T-Mobile faced these challenges as well. With a goal of getting IT associates throughout the organization to utilize the services of their QA department and to leverage the HP solutions for their daily testing activities, T-Mobile addressed these challenges head-on and overcame them. This presentation provides an overview of how T-Mobile has achieved success using HP Quality Center and SAP Test Acceleration and Optimization, and shows how the organization will ensure on-going success with this solution set moving forward.
