Since December 2007 Reinhard Clemens has been the CEO. Before that, he had been president of EDS (now HP Enterprise Services) Germany since 2003. Since January 2018 Adel Al-Saleh is the CEO of T-Systems.
T Systems has announced will cut totally 10,000 jobs in 3 years, 6,000 job cuts in Germany itself. The aim of this action is to change company loss to profit.
T-Systems was founded in 2000, when Deutsche Telekom acquired a 50.1% stake of debis Systemhaus, one of the largest IT services companies in Germany at the time. Most of Deutsche Telekom's existing service and IT businesses were then merged and incorporated under the control of one single company, the newly founded T-Systems. In 2001 T-System's headquarters were moved from Bonn to Frankfurt. In 2002 the remaining 49.9% share of debis Systemhaus was acquired and fully incorporated into T-Systems.
However, the company underwent a leadership crisis during the first years after its creation, due to different agendas of the former debis management and the leadership of the former Telekom subsidiaries. Since then, T-Systems made a number of acquisitions, most notably the purchase of gedas, the IT subsidiary of Volkswagen Group in December 2005. Since 2007, Reinhard Clemens is T-Systems' new CEO. T-Systems also supported the creation of Silicon Saxony, a major IT cluster in Germany.
In 2008 T-Systems and global IT services provider, Cognizant, have entered into a global alliance. T-Systems' India operations were taken over by Cognizant following this alliance in late March, 2008. T-Systems is also working for the German government and a market leader in Germany.
In 2009, T-Systems came with another wing in India (T-Systems ICT India Pvt. Ltd.) to support its global partners. T-Systems ICT India has its head office in Pune and have set up another 'Point of Production' in Bangalore in April 2016 and is expanding to provide its ICT services also to global customers of T-Systems International. Since Sept. 2016, Laszlo Posset is the Managing Director of T-Systems ICT India. Before that, Vivek Krishnatray managed the company's Indian operations.
