Three Major IT Functions
Governance refers to the implementation of operational parameters for working units and individuals' use of IT systems, architecture, and networks. The governance of the master data is based on workflow processes that integrate business rules and subject matter domain expertise. This is part of the conventional IT security as well as the data assurance for which the IT department is also responsible.
Infrastructure refers to the hardware components, the network, the circuitry, and all other equipment necessary to make an IT system function according to the established needs and system "size" of the City.
Functionality is perhaps the most apparent task performed by the IT department. It refers to creating and maintaining operational applications; developing, securing, and storing electronic data that belongs to the organization; and assisting in the use of software and data management to all functional areas of the City.
IT Network Responsibilities
The IT department oversees the installation and maintenance of computer network systems within the City. Its primary function is to ensure that the network runs smoothly.
The IT department must evaluate and install the proper hardware and software necessary to keep the network functioning properly. This includes working within a budget that allocates the amount of money the City can afford on network devices and software. The IT department must make sure that the equipment it invests is both optimally serving the needs of the company and not going over budget.
Most people are aware that the IT department focuses on the success of computer operations and other information technologies needs within the City. However, with many new forms of electronic communication replacing older technology, communication is being redefined and is now referred to as "telephony." This includes point to point phone calls as well as conference calls. Video and web conference also fall under this category and include other forms of technology necessary to facilitate communication: network drives, electronic mail (email), and secure servers.
The IT department must fully understand how these systems work and interact with each other. The department must also ensure that these systems remain operational at all times.
