UseCaseKonzept

UseCaseKonzept is a structured approach used in requirements engineering to describe the expected interactions between users or external systems (actors) and a software system in order to achieve specific goals. The concept centers on capturing how the system should behave from the user’s perspective and defining the scope of the system under study. A UseCaseKonzept typically organizes information around a set of use cases, each representing a goal the actor wants to accomplish and the sequence of steps that achieve that goal.

A typical UseCaseKonzept includes core elements such as the system boundary, identified actors, and individual use cases. For each use case, essential details are documented: the trigger or initiating event, the main (happy path) flow, alternative and exceptional flows, preconditions that must be true before execution, postconditions or outcomes after completion, and any business rules, data requirements, or non-functional constraints relevant to the scenario. Diagrams (such as use case diagrams) and textual descriptions are commonly used to convey the information, with considerations for interfaces and dependencies between use cases.

The purpose of a UseCaseKonzept is to guide design and validation by providing a clear, testable contract between stakeholders and the development team. It supports traceability to requirements and test cases, and it is frequently integrated with iterative or agile workflows, where use cases are refined into user stories or backlog items. While closely related to UML’s use case concepts, the term “UseCaseKonzept” is commonly used in German-speaking contexts to emphasize a comprehensive, scenario-based understanding of system behavior.
