Questions tagged [use-case]

  • Documenting use-cases in textual or tabular form
  • Modeling use-cases in UML. In this case add .

You may also use this tag for questions related to the implementation of use-cases (e.g. with )

Do not use this tag for for questions about:

  • suitability of programming techniques or features to solve implementation issues. The remaining tags should be sufficient for people to find your question.
  • exclusively UML use-case diagramming syntax. Prefer the tag combination in this case.
