1) Draw system and name it
2) Add the users as temporary actors
3) Add systems
4) Add devices:
Interview Questions: Are there any devices that will interact with the system? For example, a security system might interact with door and windows sensors. A manufacturing control system will communicate with automated machinery.
Responses: 1) List the devices and their purpose, 2) Determine whether or not they should be included in the discussion: that is, apply the Criteria for Inclusion, 3) For each device you choose to keep, create a 'draft' actor ( we are not done)
5) Convert users, systems, and devices to actors
6) Add the use cases
7) Merge actor #2 with actor #1
8) Merge use case #4 and #5. Use the name for use case #4
9) Add the associations
9.1) Eliminate the user case #2 because it is not visible to any actors outside the system.
10) Finished use case diagram
