10 Principles for the successful Reorganization of the TSI ITC Landscape• 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 GmbH.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.
