PublicationAdapting the Data Warehouse Concept for the Management of Decentralized Heterogeneous Corporations( 2000-01-01)One of the major current business trends is gaining market power by mergers and acquisitions and by selling off those business units which are considered inefficient or which no longer represent core competencies. The goal of our paper is to conceptualize an IS architecture which on the one hand enables a speedy integration of decentralized and heterogeneous business units and on the other hand facilitates their selling off. Such a Management Middleware is developed basing on the data warehouse concept. The core of the Management Middleware is an information pool in which specific decision relevant information of the entire corporation are stored. In contrast to a data warehouse, the information pool is not a read-only data store, but a read-write information junction which allows for information input by decentralized units and, at the same time, allows the access to information stored by headquarters or other units. Only a two way information center supports the creation of management in-formation and at the same time enables a decentralized, but integrated decision-making and corporate management. The decentralized business units own data marts which contain specific decision relevant information adapted to their individual decision problems.Type: journal articleJournal: Journal of Data WarehousingVolume: Vol. 5Issue: 1

PublicationBeyond Enterprise Architecture Modeling - What are the Essentials to Support Enterprise Transformations?(Köllen, 2013-09-05)Reichert, ManfredIn recent years, many different modeling techniques and languages were developed in order to allow for an efficient and appropriate enterprise architecture management (EAM). Recently, EAM is no longer only seen as a means to ensure business/IT aligment but further as a means to support fundamental changes of the organization, often called enterprise transformation (ET). In a joint project with a group of practitioners we aim at developing a framework that provides guidance on how EAM can support such ETs and thus leverage the benefit of modeling. Our design results after more than one year of research reveal different types of EAM, areas of action in ETs and ET activities that can be supported by EAM. The findings show that modeling techniques or languages should focus on constructs like transitions, benefits or risks in order to increase their value for ET support.Type: conference paper

PublicationJustification of Data Warehousing ProjectsProject justification is regarded as one of the major methodological deficits in Data Warehousing practice. As reasons for applying inappropriate methods, performing incomplete evaluations, or even entirely omitting justifications, the special nature of Data Warehousing benefits and the large portion of infrastructure-related activities are stated. In this paper, the economic justification of Data Warehousing projects is analyzed, and first results from a large academia-industry collaboration project in the field of non-technical issues of Data Warehousing are presented. As conceptual foundations, the role of the Data Warehouse system in corporate application architectures is analyzed, and the specific properties of Data Warehousing projects are discussed. Based on an applicability analysis of traditional approaches to economic IT project justification, basic steps and responsibilities for the justification of Data Warehousing projects are derived.Type: conference paper

PublicationManagement Middleware for Integrating Decentralized Heterogeneous CorporationsOne of the major current business trends is gaining market power by mergers and acquisitions and by selling of those business limits which are considered inefficient or which no longer represent core competencies. The goal of our paper is to conceptualize an IS architecture which on the one hand enables a speedy integration of decentralized and heterogeneous business units and on the other hand facilitates their selling off. Such a "Management Middleware" is developed basing on the dataware house concept. The core of the Management Middleware is an information pool in which specific decision relevant information of the entire corporation are stored. In contrast to a data warehouse, the information pool is not a read-only data store, but a read-write information junction which allows for information input by decentralized units and, at the same time, allows the access to information stored by headquarters or other limits. Only a two way information center supports the creation of management information and at the same time enables a decentralized, but integrated decision-making and corporate management. The decentralized business units own data marts which contain specific decision relevant information adapted to their individual decision problems.Type: conference paper
