In this example, Agency X has set the criticality of the Ombudsman Issue Tracking System to be the same as the criticality of the Ombudsman Function. (In this case 73-96 hours.) The criticality of the application could be less than the function if there is a documented, tested manual process in place. Agency X has not tested their manual process for over a year so they chose to match the criticality of the application to the function.
The length of time the business application can be unavailable or non-operational without significant adverse affect.
