BA28 – Requirements Analysis and Use Cases
This course provides a strong foundation in the mechanics of use case diagramming and writing textual descriptions of use cases. In this highly interactive workshop, you will learn how to enhance and refine your use case skills, how to involve your stakeholders in the use case process, and how to develop use cases that provide valuable information to the designers and testers. Use cases that meet the needs of designers can be too technical and too detailed for other stakeholders. Use cases that satisfy business users are usually not very helpful to designers and testers. How do you satisfy these two disparate interests? And how do you handle the details like business rules, data validations and user interface specifications?
Course Objectives
Employ use cases to elicit requirements, at a business, system or subsystem level Employ use cases to document the scope of a project Write use cases in a clear and unambiguous way. Model use cases with workflow diagrams Plan and divide up the project work based on your use cases Manage a use case as it evolves over time and goes through many changes
