Computer operations whose execution would increase usage costs may require use of authorization and notification plug-ins to prevent unauthorized execution. The command may be designed to only execute properly if the authorization and notification plug-ins are properly registered. The computer system customer designs the authorization and notification plug-ins based on standard application programming interfaces to suit the customer's business practices and links them to the computer operation. The computer operation executes the authorization plug-in to determine if the proper authorization plug-in parameters have been specified and verify that the command is authorized. If authorization is granted, the computer operation checks to see that the notification plug-in is given the correct parameters, executes the computer operation, and then executes the notification module to notify the necessary personnel. Both authorization and notification plug-ins return errors that are passed to the user through the computer operation.
