The following article presents an approach on the extension of WorkDesigner—a simulation-based software tool for the strain-based staffing in industrial manufacturing—for the prospective design of IT work places. After a short introduction of WorkDesigner, the common economical and technical need for the individual design of IT work places is described in the following chapters. Here the current mega trend Digital Transformation takes center stage. Chapter 4 presents additional parameters for the adaption of WorkDesigner to the drafted “digital” needs. Finally, the results and the future developments are discussed. © Springer International Publishing Switzerland 2017.

Information Systems play an important role in achieving sustainable solutions for the global economy. In particular, Information Systems are inevitable when it comes to the transition from the "current" to the "smart" power grid. This enables an improved balancing of both electricity supply and demand, by shifting load - based on the projected supply gap and electricity prices - on the demand side smartly. As this requires a specific Information System, namely a Demand Response system, we address the challenge of designing such a system by utilizing the design science approach: determining general requirements, deducing the corresponding information requirements, analyzing the information flow, designing a suitable Information System, demonstrating its capability, and, finally, evaluating the design. The design process is reiterated fully until a viable solution, i.e. an IS artifact, has been developed. This paper describes both the design process as such and the final IS artifact. Moreover, we summarize our lessons learnt from using and adopting the design science approach within this practical, bottom-up case study. © 2013 Springer-Verlag.

In this paper we present a novel approach to assess the impact of new and existing services on traffic volume in current and future backbone networks. Several proposals to model traffic load in access and backbone networks exist in the literature. These proposals consider current Internet traffic like http, smtp, ftp and Peer-to-Peer (P2P). We expect, however, that there will be a change in traffic load for future networks caused by services like IP Television (IPTV), Video on Demand (VoD) and Virtual Private Networks (VPN). Additionally, population-based models may no longer be applicable due to the widespread use of service-providers and hierarchical routing through network peering points. Therefore, it is important to reassess future traffic volumes and traffic patterns and to identify those services that have the most impact on the networks. We model today's traffic volume of each of the described services and estimate future traffic volumes taking peering points into account. To illustrate the different traffic flows and to characterise the traffic distribution we apply our results to a Germany reference network. © 2010 John Wiley & Sons, Ltd.

This article proposes a dynamic migration planning methodology for communication networks. Aimed at providing optimal technical performance, the approach takes into account dimensioning of network infrastructure and services, as well as evaluation of revenues and costs. As a result, the migration planning method provides a cost-effective network deployment plan based on an optimal stepwise upgrade strategy. Market information, existing infrastructure, costs, and demand forecasting are then considered in order to determine this strategy by solving a combinatorial optimization problem. It is described theoretically, and a techno-economic evaluation framework is introduced to assess its financial feasibility. The model is a suitable guideline to tackle migration problems commonly solved by using anticipated, single- ,and multi-period planning techniques. Considering a particular example, a study on migration toward fiber to the home is analyzed. Fiber to the cabinet/building architectures are then proposed as possible intermediate steps in the migration path to fiber to the home. Finally, a case study for an existing access network is analyzed. © 1979-2012 IEEE.

This paper develops an investment/pricing model for the deployment of basic broadband networks which, along with other applications, is applicable to publicprivate partnership projects. In particular, a new investment model is suggested to be used for finance deployment over a longer term by enabling both private and public investors to participate in the roll-out of next generation access (NGA) infrastructure. This so-called "long-term risk sharing concept" has several notable benefits compared with the traditional regulatory approach. Above all, the model enables both private operators and public authorities to share the risk of investing in NGA infrastructure. Thus the model offers a way for public authorities to achieve a timely and countrywide roll-out of NGA networks, including in areas where NGA investment would otherwise not occur. © 2010 Elsevier Ltd.

Products in the telecommunications industry consist of several modules that in sum create the customer benefit (e.g., Multi-Play products). Each module embodies its own lifecycle, which implies an additional product complexity in terms of module design, module management and module removal from the product. The authors provide reasons why the holistic view on the product lifecycle management is critical for an efficient PLM, and present a new approach for PLM-Processs Management in a multi-lifecycle environment The paper closes with the presentation of a short case study validating the proposed process design for a company in the telecommunications industry.

Network operators are increasingly competing with triple play offers from cable providers for both broadcast customers and telecommunications customers. In recent years they have invested in IPTV platforms and launched their own IPTV services. This has brought a new question on the regulatory agenda: shall network operators be obliged to offer wholesale access to their IPTV platform? And if yes, should the new wholesale IPTV product be regulated in the same way as traditional wholesale access? Or should traditional regulation be modified? While the majority of countries have so far no regulatory rules in place, some national regulators have started to become active in this market segment. In order for alternative network operators to realise multiple play offers including IPTV they must be able to match the offers of the incumbent operators. Such replicability with respect to telecoms infrastructure is in principle no problem as long as regulatory rules on local loop unbundling and related facilities are in place. But what if incumbent operators are neither required to offer unbundled access to their FTTH local loops nor do alternative network operators have access to sub-loop unbundling? It is for this reason that many argue some form of direct access to the incumbent multicast equipment needs to be provided. Otherwise the provision of IPTV services will be restricted to large network operators. The paper demonstrates that the regulation of wholesale access to IPTV depends above all on country specific conditions. Ex-ante regulation of access to wholesale broadband services over any DSL technology and any transport technology (ATM and Ethernet) in the sense that the SMP operator is obliged to offer a multicast functionality that allows competitors to offer TV services should be bound to a number of requirements: (1) the demand characteristics such as demand for bundled products. A precondition for determining regulatory obligations with respect to the provision of wholesale access to IPTV platforms should be that multiple play offers are the dominant form of providing telecom services. (2) The lack of cable TV operators exerting competitive pressure at the retail level for triple play products. (3) A lack of LLU in the country, so that alternative operators need a multicast WBA access to offer multiple play services. The paper is organised as follows. The first section of the paper briefly describes the technical and market characteristics of wholesale IPTV access. The second section considers the impact of IPTV wholesale access regulation on competition, investment and broadband diffusion. The third section examines regulatory issues concerning access to wholesale IPTV in more detail. The final section gives key recommendations for a regulatory strategy on wholesale broadband access to IPTV. © 2013 Elsevier Ltd.

The hidden paradigm behind modelling the enterprise capabilities is based on Ford's and Taylor's idea of sequencing activities and taking the best in class approaches. It has once proven to be suitable for mass production of goods. While the paradigm is still the basic modelling assumption for shaping enterprise capabilities, the environmental and social basis for enterprises have changed. The business has moved from mass good production to massive individualized services around goods, where customers can place unpredicted change requests almost at any time. The fact that such events occur unpredicted does not mean they occur rarely. The exception to the lucky path is basically the routine. How the reaction to such unpredicted events look like is shown by the inflationary usage of e-mails, instant messages, phones, and meetings. It seems that communication is about to become the new paradigm. Putting massively personalized services on top of complex products asks for fitting architectural structures. Ford's hidden paradigm fails to master the resulting architectural complexity due to the lack of the concept of "communication". What enterprises need to master is an enterprise architecture driven by communication. The proposed paper discusses a methodology to create an enterprise architecture that promotes the communication-centric paradigm using the TOGAF framework. We describe how the role of individuals within an enterprise and the communication paths between them are used to create an enterprise architecture that is easily understood and accepted by end-users. We also show how architecture planning on business, application, and data is performed using the concepts of subject-oriented business process management (S-BPM) in rapid architecture cycles, creating greater agility. © Springer International Publishing Switzerland 2014.

Market changes have forced telecommunication companies to transform their business. Increased competition, short innovation cycles, changed usage patterns, increased customer expectations and cost reduction are the main drivers. Our objective is to analyze to what extend transformation projects have improved the orientation towards the end-customers. Therefore, we selected 38 real-life case studies that are dealing with customer orientation. Our analysis is based on a telecommunication-specific framework that aligns strategy, business processes and information systems. The result of our analysis shows the following: Transformation projects that aim to improve the customer orientation are combined with clear goals on costs and revenue of the enterprise. These projects are usually directly linked to the customer touch points, but also to the development and provisioning of products. Furthermore, the analysis shows that customer orientation is not the sole trigger for transformation. There is no one-fits-All solution; rather, improved customer orientation needs aligned changes of business processes as well as information systems related to different parts of the company. © Springer Science+Business Media, LLC 2011.

The telecommunication market is experiencing substantial changes. New business models, innovative services, and technologies require reengineering, transformation, and process standardization. Enterprise Architecture Frameworks support the transformation by specifying methods, procedures, and reference models. With the Enhanced Telecom Operation Map (eTOM), the TM Forum offers an international de facto reference process framework, based on specific features and requirements of the telecommunication industry. However, this reference framework only offers a hierarchical collection of processes on different levels of abstraction; a control view in terms of a sequential ordering of tasks and hence a real process flow as well as an end-to-end view on the customer are missing. In this paper, we extend the eTOM reference model by reference process flows, in which we abstract and generalize the knowledge about processes in telecommunication companies. With reference process flows, we aim to assist companies in achieving a structured and transparent re-structuring and re-design of their processes. We demonstrate the applicability and usefulness of our reference process flows in two case studies, and evaluate them by means of criteria for reference model evaluation. Our reference process flows have been accepted as a standard by the TM Forum and published as part of eTOM version 9. We further elaborate on those components of our approach which can be applied outside the telecommunication industry. © 2013 Springer Fachmedien Wiesbaden.
