The general system analysis is presented in this book in the form of considerations, components, activities, and results. This particularly includes the two components of current analysis and target concept, but also all other phases of system development. The processes accompanying system analysis are presented in a condensed manner. Furthermore, the textbook also includes the most important specific procedural models for software development. Each chapter concludes with exercises. A large part of these exercises relates to a case study that runs like a common thread throughout the entire book, encompassing all processes and results from the establishment of a project assignment in the project justification phase to the creation of the specifications document as the conclusion of the system analysis. Detailed solutions are provided for all tasks.
