10 Principles for the successful Reorganization of the TSI ITC Landscape Idea Draft Commit last update 9. 10. 02 • The ITC strategy derives from the TSI company strategy and conforms to the corporate ITC strategy, which is examined from the perspective of profitability. • The ITC architecture is based on the process model of T-Systems International Gmb. H. Central TSI and BL processes are mapped to a TSI core system. • The standard application platforms in the core system network are SAP R/3 and Siebel; within the system network, an SAP R/3 HR system provides support for human resource management. • ITC users gain access to the ITC systems via a personalized portal which is divided into three function blocks; Information, Communication and Application Services. • The TSI system network is integrated into the corporate group via the Key Information Object architecture (KIO); responsibility for content and quality is established through the business processes. • A T-Systems template, which is universal throughout the network, provides strong support for standardization. • The system network is based on a harmonized ITC system and communications platform, thus optimizing forms of operation. • The degree of internal ITC development depends on the importance of a given process for competitive strength and the availability of customizable standard solutions. • ITC projects are controlled by the roadmap, which is standard throughout the company. • Use what you sell. ======!"§==Systems= Dr. Jürgen Kratz Member of the Managing Board 20.
