    Requirements elicitation is software development teams' toughest problem today, reveals a TechTarget survey. Most teams rely on use cases and requirements management tools to get requirements right. Agile and lean development practices are also helpi... 

  • From use case diagrams to context diagrams

    It's tempting to consider use case diagrams as context diagrams because they do show context. But having one diagram for both will result in an unreadable cloud of bubbles.

About Gathering Software Requirements Use Cases

Use cases and misuse cases are modeling tools used to document software requirements. Use cases are structured in a way in which a user story or scenario is described as a user, defined by the role he plays, performs a scenario. The story would describe what should happen when the software product is used. A misuse case, in contrast, names something that should not happen, which may lead to additional requirements that can be expressed as use cases. Misuse cases help in identifying security risks to the system.
