This 2-day course is an exercise-driven course to guide students in developing well-written and effective use cases following the concepts and guidelines of the IBM/Rational Unified Process version 7. Students learn the basic concepts of RUP 7 regarding requirements specification, with emphasis on writing use cases to capture the user requirements of a software system. The course focuses on distinguishing business use cases and system use cases, properly structuring a RUP use case, incrementally writing the use case from Basic Flow to Alternate Flows, and the proper grammar and sentence structure for the use cases descriptions. Both business use cases and system use cases are studied, with multiple examples of each. Students write two complete use cases for their selected project domain.
Audience:
Business or system analysts, technical managers, and software developers who wish to learn the use case techniques of the IBM/Rational Unified Process for capturing user requirements for software system development.
Prerequisites
Experience in requirements gathering, or systems analysis is desirable, but not mandatory.
