Use Case Modeling is a structured method for identifying and modeling functional requirements from the user's perspective. It captures actors, goals and stepwise interactions in concrete scenarios and links business expectations to technical tests. The approach supports shared understanding, prioritization and derivation of implementation tasks.
Use this profile to understand the building block briefly, place it in the model, and switch to the 360° assessment when needed.
Executable approach: can be applied and produces an outcome.
What organizes, connects, or makes decisions possible.
Use case modeling describes the goals actors pursue with a system and the services the system provides for those goals.
Use cases were shaped by Ivar Jacobson in the late 1980s and early 1990s and later standardized in the Object Management Group’s UML.
Name actors and their goals, set the system boundary, describe relevant interactions, and review the scenarios with stakeholders.
A role outside the system that interacts with it.
A goal or result an actor expects from an interaction with the system.
The boundary between described system services and their environment.
Use case models expose user goals and system scope early and give requirements a form stakeholders can review together.
