Overview

Kommunale Informationsverarbeitung Reutlingen-Ulm (KIRU) was a municipal regional data processing centre (kommunales Gebietsrechenzentrum) organised as a Zweckverband — a special-purpose association of municipalities — with its seat in Ulm, Germany. It was formed on 1 January 2002 through the merger of two predecessor Zweckverbände: the Interkommunales Rechenzentrum Ulm (founded 1969) and the Regionales Rechenzentrum Alb-Schwarzwald (founded 1972). KIRU's core territory was South-East Baden-Württemberg. Its members included 349 cities and municipalities, one urban district (Stadtkreis) and 13 rural districts (Landkreise). It cooperated with the two partner data centres in Baden-Württemberg, the Zweckverband Kommunale Datenverarbeitung Region Stuttgart (KDRS) and the Zweckverband Kommunale Informationsverarbeitung Baden-Franken (KIVBF). It primarily served members in the regional associations of Neckar-Alb, Schwarzwald-Baar-Heuberg, Donau-Iller, Bodensee-Oberschwaben and Ostwürttemberg. KIRU operated from two locations, Ulm and Reutlingen, and employed more than 400 people across both. Its subsidiary was Interkommunale Informationsverarbeitung Reutlingen-Ulm GmbH (IIRU GmbH), based in Reutlingen. Beyond data processing, KIRU qualified specialists and managers from municipal administrations for work in the municipal IT environment, offering on-site training, seminars at its Reutlingen and Ulm seminar houses, and courses in social competence and work methodology. Following an amendment to the ADV-Zusammenarbeitsgesetz in February 2018, the data centres KIVBF, KIRU, KDRS and the Datenzentrale Baden-Württemberg merged on 1 July 2018 into a joint municipal IT service provider named ITEOS, a legally capable public-law institution (Anstalt des öffentlichen Rechts) based in Stuttgart. The supporting bodies (Träger) of ITEOS were the Zweckverbände of the municipal data processing association and the State of Baden-Württemberg. After a trademark dispute with International Telecom Operation Services GmbH (I.T.E.N.O.S.), a subsidiary of T-Systems, further use of the ITEOS brand and company identifier was prohibited. As a result, ITEOS was renamed Komm.ONE effective 1 July 2020. KIRU therefore no longer exists as an independent entity; its functions continue within Komm.ONE.

History

KIRU's roots lie in two municipal data processing associations founded in the late 1960s and early 1970s. The Interkommunales Rechenzentrum Ulm was founded in 1969, and the Regionales Rechenzentrum Alb-Schwarzwald was founded in 1972. On 1 January 2002 these two Zweckverbände merged to form the Kommunale Informationsverarbeitung Reutlingen-Ulm (KIRU), a municipal regional data processing centre with its seat in Ulm. As a Zweckverband, KIRU was owned by its member municipalities rather than by private shareholders. Its core territory was South-East Baden-Württemberg, and its members comprised 349 cities and municipalities, one urban district and 13 rural districts. It cooperated with the partner data centres KDRS (Stuttgart region) and KIVBF (Baden-Franken), and primarily served members in the regional associations of Neckar-Alb, Schwarzwald-Baar-Heuberg, Donau-Iller, Bodensee-Oberschwaben and Ostwürttemberg. KIRU operated two sites, in Ulm and Reutlingen, with more than 400 employees in total. Its subsidiary, Interkommunale Informationsverarbeitung Reutlingen-Ulm GmbH (IIRU GmbH), was based in Reutlingen. In addition to data processing, KIRU ran a training programme for specialists and managers from municipal administrations, combining on-site training, seminars at its Reutlingen and Ulm seminar houses, general and specialised IT courses with practical PC exercises, and courses on social competence and work methodology. In February 2018 the ADV-Zusammenarbeitsgesetz was amended, enabling the merger of the municipal data centres. On 1 July 2018, KIVBF, KIRU, KDRS and the Datenzentrale Baden-Württemberg merged into a single municipal IT service provider named ITEOS, a legally capable public-law institution (Anstalt des öffentlichen Rechts) headquartered in Stuttgart. ITEOS was supported by the Zweckverbände of the municipal data processing association and by the State of Baden-Württemberg. The ITEOS name proved legally contested. A trademark dispute with International Telecom Operation Services GmbH (I.T.E.N.O.S.), a subsidiary of T-Systems, resulted in a prohibition on further use of the ITEOS brand and company identifier. Consequently, effective 1 July 2020, ITEOS was renamed Komm.ONE. KIRU thus ceased to exist as an independent organisation in 2018, and its successor continues to operate under the Komm.ONE name.
