For an ATM use case diagram, which of the following would be the actors? Select all that apply.
Correct Answer
(1) ATM Customer (bank card holder)
(2) Bank Back-end System (account management system)
(3) Bank Administrator or Maintenance Technician
Explanation
Actors are people or systems that interact with the ATM system: The customer interacts directly, the bank's back-end system is an external system actor (for account verification and transaction processing), and the administrator/technician interacts for maintenance. The ATM hardware is part of the system itself, and the development team does not interact with the operational system.
