1. Develop a list of use cases for the ECSS (please do not include multiple tables). Present your list in a table that includes the participating actors, use case name and a brief use case description. For those identified via Event Decomposition technique, you need to include the event and type of event. (Note that some use cases are already identified below. Include these in your lists.) (8 points) Hint: You NEED to use CRUD to identify at least two use cases (Please add a note at the bottom of the table to explicitly state which use case(s) are identified via CRUD).
2. Create a domain model class diagram for the ECSS, including all classes, attributes, associations, and multiplicity. Show association classes and generalization hierarchies where appropriate. 
3. Create a fully-developed use case description for the use case Find caterer. Follow the template provided at the end of this handout. 
4. Draw an activity diagram to represent the flow of activities for the use case Generate credit payments report. 
5. Draw a system sequence diagram for the use case Provide feedback. 
6. Draw a state machine diagram to show the possible states and transitions for a Catering Job object. Label each state with the state name. Label each transition with the appropriate transition name, guard condition (if appropriate) and action expression (if appropriate).
