Elements of organizations describing mission areas, common/shared business services, and organization-wide services. Mission/business segments can be identified with one or more information systems…

A mission/business segment refers to a distinct area or grouping within an organization that defines specific mission areas, common/shared business services, and enterprise-wide services. Information systems are typically identified and managed within these segments to collectively support their associated mission or business processes.

A mission/business process is a sequence of activities or tasks, which is supported by systems within a segment, but it is not the overarching segment itself.

Common/Shared Business refers to a *type* of service that might exist within a segment, but it is not the segment itself.

Operation/Maintenance is a phase in the system lifecycle focused on keeping systems running, not an organizational structure or segment definition.
