Improving an existing CIS by examining customer decisions development and planing to increase the effectiveness for ISC and ISM

Inhaltsangabe:Abstract: More and more companies apply electronic information systems in all their business areas. In the past many of these systems pertained to one specific user group. However due to high efforts and investments for maintaining these information flows companies tend to increase the amount of attracted user groups. Thereby the users must deal with more and more information every day. In addition they must select the relevant information which serves as a basis for their decisions on their own. This procedure and the included irrelevant information generate high efforts due to re-work requirements. Therefore users reject more and more information. All these conditions combined with a two-user group-oriented customer information system require output adjustments to the user-specific needs. Consequently it is necessary to identify the users their needs and the potential effectiveness of specific information provided by a specific system. This thesis refers to theoretical analysis models for generating an optimal concept. Thereby it considers methods analyzing the original information system aim user groups their needs and the way the provided information flow can meet all these requests. These considerations represent actual conditions of Varta Gerätebatterie GmbH. Afterwards this research compares the optimal with the actual situation in order to deduct appropriate improvement steps. Finally this thesis suggests possible integrations and constitutes the related advantages and disadvantages based on cost accounting and information management theory. The information flow analysis demonstrates the importance of finding appropriate methods and the key role of defining all users. Moreover it emphasizes the significance of adjusting this flow to user needs in regular intervals due to the rapidly changing environment. The analysis of the information preparation and output indicates that communication plays a key role in exchanging informa
