Concepts

Use cases have proven to be a very powerful technique for deriving a lot of details about requirements. Specifically, Use Cases help derive details on interactions between the system and all types of users and all systems interacting with it. These details are equally important for the development team and the test team in order to deliver a high quality system. Although many projects have used some form of Use Cases, very few projects I am aware of have actually reaped the full benefits of this powerful technique. In this course, attendees learn how to effectively develop, analyze, and validate Use Cases. In addition, test teams and development teams learn how to derive tests based on Use Cases.

Participants will learn:

Attendees will achieve the following objectives:

• Learn how to effectively participate in a Use Case development and analysis sessions
• Master the process of using Use Cases to find system requirements that would otherwise be missed
• Learn how to identify scenarios that must be handled by the system and tested by the test team
• Learn how to systematically derive test cases and test procedures from use cases
