  10. Traceability Matters

  11. Analyzing results • SMEs are assigned a story • Extract requirements • No differentiation between functional and non-functional • Enter into EA • Trace to User Story Sentence

  12. The Big Stuff • Use Case • UI Mock Up • Robustness Diagram

  13. Use Cases • Describes a given piece of functionality • Detailed list of the actions performed by each actor • Named by a verb phrase

  14. Use Case Diagram • The big picture

  15. Use Case Text Name: SR.M.MD.MTMR.1 Access Material to Material Relationship Date modified: 3/31/2010 11:58:23 AM Preconditions: System has applied security (Contract Authority). Material Selected. Associated Material tab selected.

  16. Basic Paths Basic path: View Associated Material  The system displays the Associated Material list with standard search facility.  The technician enters search criteria.  The system displays the Associated Material Summary component with associated material records that match the search criteria.

  17. Alternate Paths Alternate path: Create Associated Material The technician clicks Select Associated Materials from the Associated Material list. The system displays the Material List modal component with standard search facility. The technician selects material(s) and clicks Add to Associated Material. The system adds the selected material(s) to the Associated Material list. The technician enters associated material data, invoking Access Applicable Record with Active/Inactive Data SR.G.UA.MEIO.2, and clicks Save from the Associated Material component. The system validates and saves associated material data.

  18. Alternate Paths for Errors Associated Material Data Validation Fails The system displays the associated material component with error message.

  19. Rules for Use Cases • ITI has a methodology standard document • "One very busy person" • Your text book has some nice lists on pages 137 and 139

  20. UI Mock Ups • Done along with use cases • Big debate over level of resolution • White board? • Screen grabs? • Tool?
