Scenarios
Scenarios are so useful that we have devoted the whole of Chapter 6 to them. Scenarios show the functionality of a business process by breaking it into a series of easily recognizable steps, written in English (or whatever language you use at work) so that they are accessible to all stakeholders. The IceBreaker analysts used scenarios to describe the business processes and present their understanding of the needed functionality. These scenarios were then revised as needed—different stakeholders took an interest in different parts of the scenario, and after a short time, the business analysts were able to have everyone understand and come to a consensus on what the work was to be.
Once they are agreed, the scenarios become the foundation for the requirements.
