The Technology Radar - an Instrument of Technology Intelligence and Innovation Strategy

This paper analyzes the establishment of a technology intelligence tool of the Deutsche Telekom Laboratories - the technology radar. Goals and method are contrasted to approaches discussed in literature. After the presentation of exemplary findings of the technology radar, the role of the technology radar within the innovation and technology management of the Deutsche Telekom is being discussed. The paper closes with lessons learned, key success factors are being highlighted and recommendations for the introduction of technology intelligence systems are given

ISA – Towards an Integrative Service Architecture for Telcos

Abstract Both increasing competition from established web companies and over-the-top players, and business opportunities from new Web 2.0 related services give reason to telcos to open up their service delivery platforms for integrative offerings in the frame of the Web 2.0 service ecosystem. While the web community provides innovative and hyped services that are open and can enrich telco service offerings, telcos help the user to manage digital assets across networks and devices with superior user experience. To benefit from both sides, users desire maximum flexibility and ease of use in deliberately combining components from Web and telco players to integrated services. From telcoss point of view, new models of co-creation need to be implemented to meet this demand, and to extend their reach beyond the traditional network customer basis. This paper investigates and discusses major design principles needed for a telco SDP architecture bringing together the best of telco and Web worlds: establishing the enabler sphere, opening up to bidirectional service integration and supporting user centricity as a fundamental concept of the Web 2.0.

A Role-Based Architecture for Seamless Identity Management and Effective Task Separation

Today’s on-line end user experience is compromised by the need for managing multiple redundant identities for access to various services — such as email accounts, in order to ensure a clear separation of tasks that users perform in different capacities. Approaches based on Single Sign On (SSO) have focused on the provision of interoperability and trust management solutions required to allow users to log in once and use multiple on-line services. In this paper, we argue that Single Sign On provides neither adequate privacy preservation nor sufficient fine-grained separation of tasks, as it requires that a user performs all tasks — whether e.g. personal or professional — using the same identity. We propose Identity and Role Management (IRM), a new approach to identity management, combining the benefits of SSO and user-centric frameworks: it allows a user to be authenticated as conveniently as with SSO, to still achieve an effective separation of tasks she performs in different capacities through the use of different roles, and to retain full control of her private and sensitive data. Additionally, it facilitates fine-grained service customisation, supporting a personalised on-line experience. Our experiments with real users demonstrate the effectiveness, transparency, and user acceptance of our solution.
