Questions tagged [use-case]

Use-cases capture and specify requirements of a system and stakeholder expectations with a view to the objectives of its users. Do not use this tag for for questions about suitability of the use of techniques/features to solve implementation issues.

Purpose

Use-cases capture and specify requirements of a system and stakeholder expectations with a view to the objectives of its users and the added value.

Tag usage

Use this tag for questions relating to the problems that a system is supposed to solve, and to use-case analysis and design:

  • Identifying and scoping use-cases in narratives and requirements
  • Analyzing the actors and their interactions with a system
  • Abstracting use-cases from specific scenario and user-interfaces
  • 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.
