Task 1: Use Visual Paradigm to create an activity diagram for each of the three use cases below.

Task 2: Use PlantUML to create a system sequence diagram (SSD) for each of the three use cases below.

Use Case 1 Agent Determines Priority Primary Actor Agent ITSD Scope Sub-function Level Description Numeric values for urgency and impact are used to calculate priority, which is then mapped to a word for understandability. Because priority calculation is required for different types of tickets, this use case is intended to be called or executed by other use cases. The infomation for a ticket is being added. Precondition(s) Minimal Guarantee(s) Priority is not determined. Success Guarantee(s) Priority is determined. Main Success l. Calculation of ticket priority is initiated by System Scenario/Flow 2.
