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 constit...
