Analysis: Requirements, Risks, Constraints

UML support for Analysis to be discussed include:

• Use cases and actors are used in use-case diagrams to visualise, capture and describe functional requirements at the requirements analysis phase of the software development life-cycle. Use case diagrams provide means to communicate with domain experts to refine the conceptual model of the system being designed. They provide ``snapshots'' of different aspects of the system required.
• Domain analysis using static domain class diagrams ( encapsulating software structure), as well as state transition diagrams (of changes in an object), sequence diagrams (event sequence corresponding to a functionality) and activity diagrams (of work-flows) and parallel processes capture static and dynamic behaviour of the system and its constraints.
