Steps
Detail use cases and scenarios
Some use cases and scenarios might need to be described in more detail to validate the understanding of the requirements and to permit software development to begin. This does not imply that all use cases and scenarios will be detailed prior to commencing implementation on them. The level of detail captured will vary depending upon the needs of the project and the complexity of the use case. Capture the use case and scenarios details in the use case specification.
Update Use-Case Model
Based on your work detailing use cases and scenarios, update the Use-Case Model. Add, remove or update Actors and Use Cases as required. For more information on creating and structuring your use case model see Guideline: Use-Case Model. For assistance in assessing the quality of your use-case model see Checklist: Use-Case Model.
Detail glossary terms
Review the flow of the use case or scenario. If information is exchanged, be specific about what is passed back and forth. Collaborate with stakeholders to ensure that you define newly discovered domain terms, or ambiguous terms properly in the glossary. If your understanding of the domain has improved, refine existing glossary terms.
Use storyboards to visualize and validate the scenario (as appropriate)
Achieve concurrence
Review the detailed use case and scenarios with relevant stakeholders and the development team to ensure consistency with the agreed vision. Assess quality and identify any required changes.
