The 1 st study edition is based on the 2nd hardcover edition of "Business Process Engineering". Several inconsistencies and minor modifications have been carried out. This study edition is a response to many requests for a budget-priced edition for students. This edition pursues a holistic descriptive approach that is based on the Architecture of Integrated Information Systems (ARIS) developed by the author. In addition to the data view, this approach also comprises the function, organization and control views, and encompasses all phases of the information system lifecyde – from analysis, requirements definition and design specification to implementation. The reference models develo- ped here can thus serve as initial models for concrete applications. The illustrations are oriented strongly toward standard software in order to ref Iect their significance in terms of real-world representations. In par- ticular, the discussion applies examples from the R/3 system from SAP AG and from the systems from IDS Prof. Scheer Gmb H, build on concepts developed by the author. No "user description" of concrete systems is pro- vided; instead, general foundations are laid in order to facilitate a deeper understanding of the application logic that is ref Iected in standard soft- ware. An attempt is made to dose the gap between business administra- tion theory and the "operating instructions’/ of standard software.
