ACTIVITY 6 1. Write down a list of the main functions needed to be handled by the new system. 2. What are the roles that will be interacting with the system? 3. Write down a list of additional features which in principle could be included in the new system but are more likely to be held back for now and considered in the future if and when the resulting information system is subject to later review and enhancement(s). Include the list with appropriate descriptions in your report. 4. Using all the information that you know about the business so far, create a use-case diagram (with all actors/users and use cases) for the new system and include it in your report. You need to provide enough explanation about the use case diagram. 5. Select four use cases and write a brief use-case description for them. 6. Pick one of these use-cases and write a full use-case description for it. Draw and use an activity diagram in the full description. 7. You need to have the following in your report: • use case list and descriptions • the use-case diagram and its explanation • brief use-case descriptions for 4 use-cases • a full use-case description • an activity diagram
