Akteur / Actor Stick Figure - Diagram Symbol for Use Case Modeling #3302231 (License: Personal Use)

This black-and-white stick figure illustrates the standard UML notation for an “Actor,” denoting any entity-human or automated-that interacts with a system. The label “Akteur / Actor” reflects bilingual usage, especially in German-speaking technical contexts. Its simplicity ensures clarity across documentation, presentations, and modeling tools.

Used in UML use case diagrams to represent roles interacting with a system; common in software requirements documentation, academic materials, and developer guides where visual consistency and internationalization matter.
