BA28 - Requirements Analysis and Use Cases
E-Learning
Description
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?

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
This course has been expressly designed for the Business Analyst, Business System Analyst, System Analyst, and/or Requirements Engineer. The Designer, Developer and Tester who are actively involved in utilizing use cases may also benefit from this workshop.
