Execution Context

Use Case Modeling is a core requirement engineering function where Business Analysts define system use cases and scenarios. This process captures functional requirements by mapping actor interactions with the system to achieve specific business goals. It establishes clear boundaries, preconditions, postconditions, and flow of events, ensuring stakeholders understand expected behavior before design or coding begins.

The Business Analyst identifies key actors and their intended actions within the system scope.

Specific use cases are defined by describing the goal, main flow, and alternative flows for each scenario.

Validation ensures all requirements align with business objectives and technical constraints.
