Developing Requirements with Use Cases

This (2days public, 3 days online)course will allow you to refine and enhance your use case discovery and writing skills. Working in small groups, you and your peers will identify and discuss strategies &tactics that your organization should be using...

Course Outline

Master use cases to develop requirements, improve quality and solidify the link between requirements and other aspects of development.It's well documented that the most common source of delays, cancellations and defects in systems development projects is our failure to understand the project requirements. We also know that the top two causes of requirements errors are lack of input from the users and missing or incomplete requirements. As you'll see in Developing Requirements with Use Cases, identifying and writing high-quality use cases is significantly enhanced with active user input and participation. In turn, that user involvement helps to ensure that all desired system functionality and behavior is explored and understood early on. This both drastically reduces the number of missed and misunderstood requirements and also provides a sound way to manage requirements on very complex systems.

Course Outline.
