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.
Identify actors and their interactions with the system
Define primary use case goals and triggers
Map main success flows and alternative paths
Validate scenarios against business rules and constraints
Facilitate sessions to gather requirements and validate use case definitions with end users.
Create detailed specifications including actor lists, triggers, and expected system responses.
Coordinate testing strategies based on defined scenarios to verify functional accuracy.
