  2. Use case diagram - Wikipedia

    en.wikipedia.org/wiki/Use_case_diagram

    A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...

  3. Use-case analysis - Wikipedia

    en.wikipedia.org/wiki/Use-case_analysis

    Use case analysis is a technique used to identify the requirements of a system (normally associated with software/process design) and the information used to both define processes used and classes (which are a collection of actors and processes) which will be used both in the use case diagram and the overall use case in the development or redesign of a software system or program.

  4. Use case - Wikipedia

    en.wikipedia.org/wiki/Use_case

    In software and systems engineering, a use case is a potential scenario in which a system receives an external request (such as user input) and responds to it. A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal.

  5. Software requirements specification - Wikipedia

    A software requirements specification (SRS) is a description of a software system to be developed.It is modeled after the business requirements specification.The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.

  6. Use case survey - Wikipedia

    en.wikipedia.org/wiki/Use_case_survey

    A use case survey is a list of names and perhaps brief descriptions of use cases associated with a system, component, or other logical or physical entity.

  9. User story - Wikipedia

    en.wikipedia.org/wiki/User_story

    Use case flows describe sequences of interactions, and may be worded in terms of a formal model. A use case is intended to provide sufficient detail for it to be understood on its own. Template As a <type of user>, I can <some goal> so that <some reason>. [20] Title: "goal the use case is trying to satisfy" Main Success Scenario: numbered list ...
