Concepts

This course is essential for test and quality professionals, requirement engineers, business and system analysts, project managers, product managers, developers, and everyone who is involved in writing, validating and testing requirements.  It covers details on how to document different types of requirements in a form that is testable. The course adopts a model-driven requirement process.  It is based on the instructor’s experience of using models to assure completeness, correctness, testability, and precession of requirements.  The course will also discuss the elements of requirement management process.  The course will cover several requirement-based test design techniques to discover and test requirements.  The course uses a systematic scenario-based test design methodology to create test scenarios and test cases.

Participants will learn:

• Different types of requirements and how to document them
• How to evaluate requirements for completeness, precision, and testability
• Defining quality requirements as well as functional requirements
• Requirement Traceability as means of making requirements more testable
• How models can tremendously improve the testability of requirements
• How to identify test scenarios for model-based requirements
• What are the  elements of a requirement management process and learn how to build your own process
• Learn how to use requirement-based test design techniques to discover missing requirements
• Follow a systematic test design methodology to create test scenarios and test cases
• How to use Use Cases to discover and test requirements
