The focus of this paper is on the modeling of application and business process in Cooperative Information Systems. Such processes use several resources and services to achieve a common, global system goal. We integrate the proposed concepts into the framework of a formal object-oriented specification language (TROLL). The goals of our approach are to provide additional modeling support for business and application processes, to explain these processes in the underlying framework and to couple tightly the modeling of global processes and the modeling of structural aspects of the system.

There is every indication that an object-oriented view of an information system is a solid foundation for understanding its legacy organization, for relating it to the environment in which it is embedded and for guiding its reengineering. In this paper we present a framework based upon the formal object-oriented specification language TROLL, which provides an object-oriented view of legacy information systems. The aim is to combine existing methods and keep results in a common and suitable description base which provides the appropriate form for deriving object specifications from the legacy IS. We usethe language TROLL not only as description language, but also as a framework to support the maintenance engineers in their reverse engineering tasks by giving hints about what to do next to complete the object specifications. The result of the approach is a formal object-oriented specification of the legacy IS that is suitable both for developing a new IS or for reengineering the legacy system.

Abstract. Digitalization, enhanced storage capacities, and the Internet of Things increase the volume of data in modern organizations. To process and make use of these data and to avoid information overload, management information systems (MIS) are introduced that collect, process, and analyze relevant data. However, a precondition for the application of MIS is that users trust them. Extending accounts of trust in automation and trust in technology, we introduce a new model of trust in MIS that addresses the conceptual ambiguities of existing conceptualizations of trust and integrates initial empirical work in this field. In doing so, we differentiate between perceived trustworthiness of an MIS, experienced trust in an MIS, intentions to use an MIS, and actual use of an MIS. Moreover, we consider users’ perceived risks and contextual factors (e. g., autonomy at work) as moderators. The introduced model offers guidelines for future research and initial suggestions to foster trust-based MIS use.
