Concepts

Facts that every requirement analyst, developer, and project manager knows :

• No requirement is complete
• No requirement is precise
• No requirement is even testable

Analyzing requirements written in narrative text might uncover some problems, but most requirements remain ambiguous, incomplete, and missing details; even after development starts. The end result is always a release that does not meet customer needs.

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

The course uses a mix of a lecture and workshop format

Participants will learn:

• The different types of requirements
• How to evaluate requirements for correctness, completeness, consistency, precision, and testability.
• How to use models to define requirements more precisely
• How to effectively participate in a Use Case development and analysis sessions
• How to master the process of using Use Cases to find system requirements that would otherwise be missed
• How to identify scenarios that must be handled by the system and tested by the test team
