This course provides you with a systematic and disciplined approach to understanding business systems and the elicitation, analysis, documenting, and validating of business system requirements. There is a particular emphasis on identifying the need for information systems within the business, and ensuring that the resulting engineered systems provide benefit to the business in meeting defined goals and objectives. The business system requirements are represented using UML notation and progress from business requirements represented as process models, use cases, and class diagrams through to sequence diagrams, communication diagrams, and state machines. The laboratory element of the course includes the construction of a wireframe prototype (i.e., the look and feel of the business application rather than the programming and database development) to demonstrate and validate the business requirements.
