The System Administrator (SA) is responsible for the effective provisioning, installation/configuration, operation, and maintenance of systems hardware and software and related infrastructure. Typically assigned to team, the system administrator is a qualified subject matter expert, and participates in technical research and development to enable continuing innovation within the existing network systems infrastructure of an organization. This individual ensures that system hardware, operating systems, software systems, and related procedures adhere to organizational values.

Interfacing with the project manager and relevant personnel, the system administrator assists project teams with technical issues in the initiation and infrastructure planning phases. These activities typically include the definition of needs, benefits, and technical strategy; research & development within the project life-cycle; technical analysis and design; and support of operations staff in executing, testing and rolling-out the solutions. System administrator participation on specific projects is focused on smoothing the project transition from development to implementation by performing operations activities within the project life-cycle.

System administrators are accountable for systems including, but not limited to the following: Linux and Windows workstations and servers in support of the existing Information Technology (IT) infrastructure, and application systems that support asset management and accountability. In order to provide sustained operations, the responsibilities on these types of systems also involves SA interface with the general and upper level users in order to guarantee sustained support.

Whatever their area of specialization, these administrators become the “go to” guys in regards to everything system and network related. They are the first line of defense in a networking high and low profile IT environments. Network administrators manage the network, assign IP addresses to systems, servers and peripherals and ensure that the network runs picture perfect.

Network administrators actively work with project managers, system administrators, configuration managers and others during the planning, designing and upgrading of networks. Security administrators make sure the organization’s systems are secure. They may also keep a watch over employees for inappropriate network usage.
