Use Cases
Use cases have become the de facto standard for capturing and communicating detailed, functional requirements from the business community to the information technology group. Use cases provide a structured, industry-standard way of eliciting and documenting functional interaction requirements. As a fundamental component to identifying requirements for a new system, business analysts must be able to illustrate how "actors", such as end users, stakeholders, or related systems, will be affected once the new system is implemented. This process, also known as Use Case Modeling.
