Once the system is launched, staff are required to choose their department, than which school they belong to, then log in with a valid username and password to enter the main screen before they can execute any task.

The system will identify admin users automatically once they log in successfully. For staff users, their roles can be left, applicant, or approver. The followings outlined the main functions/tasks that could be performed by users in the system.
