... Once all the additional information feedback had been incorporated, the final version was reviewed and discussed several times on the phone with the main contacts at BT and Deutsche Telekom. The final versions, which are available as working reports Schmidt et al., 2010], were also reviewed by the companies' communication departments. ...
... Deutsche Telekom expected to reduce the overall IT budget by 0.2 percent in the first year after introducing a standardized data model, by 0.67 percent in the second year, and (leveraging learning curve effects) by 1.46 percent in the third year, resulting in an average annual saving potential of approx. 0.8 percent of the IT budget [see Schmidt et al., 2010]. With an estimated average proportion of the IT budget amounting to 5.3 percent of a telecommunications company's turnover [Smith and Potter, 2008], Deutsche Telekom's cost-saving potential in 2009 equaled EUR 27 million. ...

Many companies see Data Governance as a promising approach to ensuring data quality and maintaining its value as a company asset. While the practitioners’ community has been vigorously discussing the topic for quite some time, Data Governance as a field of scientific study is still in its infancy. This article reports on the findings of a case study on the organization of Data Governance in two large telecommunications companies, namely BT and Deutsche Telekom. The article proposes that large, service-providing companies in general have a number of options when designing Data Governance and that the individual organizational design is context-contingent. Despite their many similarities, BT and Deutsche Telekom differ with regard to their Data Governance organization. BT has followed a more project-driven, bottom-up philosophy; Deutsche Telekom, on the other hand, favors a rather constitutive, top-down approach. The article also proposes a research agenda for further studies in the field of Data Governance organization.

The enterprise-wide management of master data is a prerequisite for companies to meet strategic business requirements such as compliance to regulatory requirements, integrated customer management, and global business process integration. Among others, this demands systematic design of the enterprise master data architecture. The current state-of-the-art, however, does not provide sufficient guidance for practitioners as it does not specify concrete design decisions they have to make and to the design options of which they can choose with regard to the master data architecture. This paper aims at contributing to this gap. It reports on the findings of three case studies and uses morphological analysis to structure design decisions and options for the management of an enterprise master data architecture.

The enterprise-wide management of master data is a key prerequisite for companies to respond to strategic business drivers such as compliance to regulatory requirements, integrated customer management, and global business process integration. Among others, this demands systematic design of the enterprise master data architecture. The current state-of-the-art, however, falls short of guiding practitioners with regard to the design decisions they have to make and to the design options of which they can choose. This paper aims at contributing to this gap. It reports on the findings of three case studies and uses morphological analysis to structure design decisions and options for the management of an enterprise master data architecture.
